Technical HDPE polyethylene pipes for cable laying. HDPE technical pipe for cable

During the installation of communication networks, HDPE cable pipe is very often used as a protective sheath. It is often used when laying power lines. HDPE pipe very reliably protects the cable from the influence of stray currents, aggressive soil influence and mechanical damage. Cable installation technology depends on the location and purpose of utility networks.

Application of HDPE pipes for installation of communications

For laying power lines and other engineering communications apply different types HDPE pipes. They differ design features and technical parameters:

  1. When laying an electrical cable in brick wall or floor screed use a smooth black HDPE pipe.
  2. Products with corrugated outside used for hidden, semi-hidden and open method for telephone, electrical, computer and television networks operating from DC or alternating current, the value of which is less than 1000 Volts. Electrical equipment This type can function indoors and outdoors.
  3. To lay cables in the ground, HDPE pipes with a corrugated surface are used, which are characterized by high strength and elasticity, as well as ease of installation and the ability to restore the lost shape.

Depending on the product specification, it may be equipped with a probe. The probe is special design, designed for pulling cables inside the pipe. Using it, you can reduce the time for laying communications and power networks.

In the absence of a probe, the cable is pulled using special reusable equipment. In this case, the complexity of the process increases slightly, and there is also a need to purchase technical devices. In this case, HDPE pipes for cables that do not have a pull can be used several times. This is especially true with frequent repairs of communication systems.

Among the companies producing HDPE pipes for laying cables, DKS is now the most popular. This manufacturer produces Octopus corrugated pipes, which are used for installation hidden wiring inside the building. In addition, DKS produces various boxes and accessories that allow the installation of communications in full compliance with established rules.

Advantages of HDPE pipes

Compared to metal protective casings, HDPE cable pipe will cost the owner much less. This is evidenced by the fact that for laying power lines and other communications it is not necessary to use products manufactured in accordance with the requirements state standard. For these purposes, production from recycled materials is quite acceptable. Technical HDPE pipe is made from industrial waste mixed with various polyethylene additives. It changes a little performance and color of the product, but makes it possible to significantly reduce manufacturing costs, thereby reducing the cost.

Besides, communication pipes made of polyethylene low pressure have the following advantages:

  • Individual sections of the structure can be connected without the use of welding equipment;
  • The service life of the product under normal conditions exceeds 50 years;
  • Pipes are lightweight compared to metal protective casings;
  • They have a high electrical insulation rate, so they do not require grounding;
  • Do not lose their quality due to aggressive environments and corrosion;
  • They retain their characteristics even in aggressive operating conditions and can withstand temperature changes from -25 to +70 degrees Celsius;
  • They do not release condensation onto the surface and do not produce toxic substances.

The cable inside the HDPE pipe can be laid along any desired path without the use of connecting elements, because the polymer bends very well. It is especially easy to change the design of small diameter products. At the same time, you should not bend the HDPE pipes very much, because this may cause a crease and it will not be possible to stretch the cable.

Electrical cable laying technologies

The technical features of installing HDPE pipes depend on the conditions of its use and the location of the cable. These characteristics influence the list of equipment used and required design elements.

  • Installation in fencing structures

Indoor electrical cable, closed by pipe HDPE is laid using the following technology:

  1. The location of the cable is outlined;
  2. The pipe is fixed, and it can be attached to the floor using metal brackets, and to the walls and ceiling with special fastening elements with a latch;
  3. The cable is pulled so that it is positioned freely, without tension;
  4. The structure on the floor is filled with concrete screed, and in the ceiling or wall it is sealed with plaster or other materials, depending on the size protective casing.

Using HDPE pipe you can reduce the length electrical wiring and re-stretch the cable and renovation work without the possibility of damage to the surface of walls and ceilings.

When installing communications inside a building, you can use various types of connecting parts to attach individual elements of the protective case: couplings, bends and other components. However, elements with a corrugated surface are most in demand for turning in places where the structure passes through the floor slab or transition between different planes. In this case, a polyethylene pipe can be bent even at a right angle, which cannot be done without using additional elements designs. According to current installation instructions hidden electrical wiring, which is located inside walls or floors made of non-combustible materials, the use of corrugated and smooth HDPE pipes is allowed.

  • Laying HDPE pipes in the ground

This technology is in great demand when laying communications in private homes and country houses. Before starting work, you need to carefully inspect the cable and check the integrity of the protective casing. If the shell is damaged protective function polyethylene pipes will lose its meaning.

  1. Make markings and dig a trench of the required depth;
  2. A polyethylene pipe of the required size will be placed in the pit with or without broaching;
  3. The cable is pulled and laid in such a way that it is positioned freely;
  4. The pipe is covered with a layer of sand about 10 centimeters thick, and then with earth to a depth of 15 centimeters.

To quickly find the location of the cable, you can lay a special signal tape over it.

When using HDPE pipes to lay power networks underground, it is advisable not to use couplings and other connecting elements, because this may worsen the sealing of the system. Do not forget that the use of fittings when leading cables into a building is mandatory. To lay a cable on a straight section, it is best to use solid parts with a cross-sectional diameter of more than 4 millimeters. If the section is too long, then to tighten the electrical cable you need to use an elastic metal wire or a special nylon broach. Initially, they are launched into the pipe, and then the tied cable is tightened.

  • Cable laying without trench

To lay electrical cables located in places with difficult accessibility, trenchless installation technology is used. Most often it is used by utility services, because it is carried out with the assistance of special equipment and complex technology. The essence this method Cable laying involves horizontal drilling, which makes it possible to lay communications underground without disturbing the surface layer of the soil. Initially, the composition of the soil is studied, after which it is necessary to obtain permission to carry out such work. Afterwards, the installation of the cable in the HDPE pipe begins, which includes the following steps:

  1. Drilling a pilot well. The soil is punctured using a drill head that has built-in radiation and a bevel in the front part. As it enters the ground, a mixture is supplied through special holes to fill the well. It reduces the likelihood of collapse and cools hot equipment.
  2. The well is expanded using a rimmer, which replaces the drill head.
  3. Laying HDPE pipes with cable inside. The structure is pulled into the well using a drilling rig.

The main disadvantage of horizontal directional drilling technology is the complexity of the process, therefore, when carrying out such work, it is necessary to enter into an agreement with specialized organizations that have staff and necessary equipment for carrying out such work.

Cable laying with protection of low pressure polyethylene pipes ensures reliable protection communication systems for a long time, but do not forget about the installation instructions, because even a little negligence can ruin all the work.

HDPE pipe for laying cables in the ground

When choosing a product, you must pay attention to two characteristics of the pipe: the diameter of the pipe and its type.

Diameter internal section pipes must be at least one and a half times the outer diameter for cables with stranded conductors and twice the outer diameter for cables with single-wire conductors.

In each of these cases, for cables up to 10 kV, pipes with an internal diameter of less than 50 millimeters for a length of up to 5 meters and less than 100 millimeters for a longer structure cannot be used. For example, if you need to lay a cable with a small cross-section over a distance of 6 meters, then you need to use pipes with a diameter of more than 100 millimeters. When designing networks of particular importance, it is recommended to use double-walled HDPE pipes with a diameter of 110 millimeters, even in cases where some sections are less than 5 meters in length. Even though this leads to unnecessary costs, since pipes with smaller diameter and their installation is cheaper, this gives confidence in the reliability and durability of the system.

Cable routes of any size need protection from external factors and accidental mechanical damage, which can lead to a violation of the integrity of the shell of current-carrying conductors. Previously used metal pipes, concrete, brick protection are quite expensive protection methods to manufacture. The amount of work involved in constructing a shell from them is very large. Accordingly, the cost of arranging such communications is prohibitively high. An alternative is HDPE pipe for laying cables, which has high strength and a long service life.

HDPE pipe for cable laying. Low price, high quality.

HDPE pipes are designed to protect the power cable from external negative factors (mechanical, organic and chemical), as well as the effects of stray currents. Depending on the purpose of communication networks, the technology for laying them is different.

To install power lines in the ground, protective cases are used that have high strength, elasticity and the ability to self-heal to their original dimensions - corrugated HDPE pipes.

Contents of the article

Types and characteristics

Thanks to , power communication (engineering) lines can be reliably and inexpensively laid underground in any corner of the city, as well as in a private house or holiday village.

In addition, laying the wire through a protective elastic pipe underground will protect it much better from mechanical, chemical or atmospheric influences, compared to ground laying. But first of all you need to choose the right one protective case, corrugation.



HDPE pipes that are suitable for protecting cables when installed in the ground:

  • flexible corrugated pipe;
  • double-sided corrugation (the outer side is made of low-density polyethylene, the inner (smooth) side is made of high-density polyethylene);
  • products made from recycled materials (technical insulating corrugation);
  • flexible corrugation, with reinforced coating;
  • hard and smooth pipe.

Properties of HDPE cases for installation in the ground

The corrugation used for pulling power wires along the ground should not have magnetizing properties. Therefore, for its manufacture, special ceramics, plastic or asbestos cement are most often used.

The diameter of the required protection directly depends on the length of the cable you want to install: a power cable of up to 5 meters can be placed in a 50 mm pipe; if its length is 5 meters and above, a product with a diameter of 100 mm is used.

There are several layers in a HDPE pipe:

  • outer layer – protective case, made of structural steel;
  • insulating layer over the screen (PVC);
  • the screen itself (Cu layer);
  • XLPE – insulating layer along the core;
  • core (material: Al or Cu).

The current will flow through the core, behind the screen and pipe (eddy currents). Regarding production of this product, high quality manufacturing takes place in special workshops, where visual designs (layouts) are used, taking into account the mechanism for further laying the power wire.


Advantages of corrugated HDPE pipe

Differs from metal products because it is much cheaper. Both products manufactured in accordance with GOST and pipes made from recycled materials can withstand long-term operation (the characteristics and color will differ slightly).

The main advantages of this product include:

  • the cable can be laid along a curved path without the use of auxiliary frames (but, despite the increased flexibility, if the corrugation is strongly bent, it will break, and you simply will not be able to stretch the power cable);
  • under normal conditions, the operating period reaches 50 years;
  • there is no need to use welding machines to connect individual sections;
  • a corrugated pipe is much lighter than a metal pipe;
  • has excellent electrical insulating properties and does not require grounding;
  • have excellent properties, therefore they are not destroyed under the influence of external negative factors;
  • resistance to temperature changes from -25 to +75 degrees;
  • do not accumulate condensate on the ground surface, do not oxidize and do not emit toxic substances.

Methods of laying in the ground

There are two ways to lay cables in the ground using corrugated cases: with digging a trench and trenchless laying. Which one is best depends on the installation location.


The method of laying cables through a protective corrugated pipe by digging a trench in the ground is ideal for private homes and summer cottages. The installation depth must be at least 70-80 cm. This type of installation does not require additional couplings or blocks, but only for bringing the wire out from under the ground and connecting with electrical system Houses.

Trenchless cable laying in HDPE pipes is carried out in hard-to-reach places and is most often used public utilities, since its implementation requires special equipment and devices.

Trenchless laying involves horizontal, directional drilling of soil without damaging its surface. A pipe with a wire inside is installed into the resulting well.

Preparatory stage

First of all, you need to decide in the best possible way installation of a corrugated case. For this purpose, all information about the work site and soil is collected (to avoid increased influence groundwater; alkalis, acids, etc.).

Underground installation is used in the case of a normal groundwater level, good soil conditions, and the absence of obstructing buildings or roadways. Also local conditions affect laying depth cable.

Before starting installation, it is also necessary to check the condition of the exits and connections of the corrugated cases - they must be clean, with a prepared (specially treated) surface.

For easy pulling, an oily substance is applied to the wire, which, moreover, acts as an alarm for the pressure level in the pipe. The wire must not be damaged or defective. The installation must be carried out as safely as possible, therefore, before starting work, all workers are additionally instructed, their tools and special clothing are checked.

The process of laying cables in a pipe

At the power line design stage, it is necessary to determine the exact length of the channel into which the pipe will be inserted. Draw a plan for laying the power rein.

Let's look at the installation process by digging a trench:

  • on prepared soil with sand cushion(10 cm of loosened sand) a pipe is laid (without tension, in small horizontal waves);
  • we stretch the wire (the pipes can be laid with the wire already stretched inside or, by tying it to copper wire, stretch it after laying the corrugation);
  • cover the pipes with a layer of sand so that they are not visible;
  • cover them with a 15 cm layer of soil and compact it;
  • We stretch the signal tape along its entire length;
  • completely fill the trench and compact the soil;
  • We make a test measurement of the insulation resistance of the power wire.

You can stretch the cable in the pipe and install it by digging a trench yourself, without complex devices or equipment. All installation steps must be carried out according to the instructions, All materials have been tested and prepared for use.

Before purchasing it in the ground, be sure to make sure that it is not damaged by inspecting it along its entire length. Choice of quality building material and strict adherence to the installation instructions for utility power wires is the key to their long-term operation without the threat of short circuits or other life-threatening incidents.

The use of pipes for laying cables in the ground allows additional protection of communications from external influences. The article will discuss the nuances of this process and the pipes used.

Pipes used, reasons for their popularity

One of the most popular options for laying wires is to place them in the ground. To implement this method, special pipes are used.

Reasons for popularity:

  • When placed above ground, the cable may be damaged by a gust of wind, and the method described above does not have such a drawback.
  • The underground wire is much more difficult to damage, and there is also protection from external weather conditions.
  • Even if the wire is short-circuited, there will be no fire due to the protection.


There are five types of pipes designed for laying cables:

  1. Polypropylene. This material It is characterized by plasticity and heat resistance. Such pipes are easy to give the desired shape.
  2. Steel. Such pipes are not used for laying power lines in the ground. As a rule, a steel pipe for cable is used indoors, using corrugation.
  3. Made from high and low pressure polyethylene. This type of pipe is lightweight, durable and has a long service life, and it also has corrosion protection.
  4. Asbestos-cement. These are heavy pipes and contain asbestos, which is harmful to the human body.
  5. PVC pipes.


The greatest demand at the moment is for pipes made of low-density polyethylene (abbreviated as HDPE). There are a huge number of varieties of such products: smooth-walled rigid, double-walled, corrugated pipes and so on.

Corrugated pipes for laying cables in the ground have high elasticity, as well as heavy weight due to the reinforcing mesh inside. In addition to corrugation, double-wall pipes contain a layer of HDPE.

One of the main advantages of laying the cable inside such a product is that it will be completely hidden from the environment. The pipes are durable; the manufacturer claims that they can last up to 50 years. In reality, this period turns out to be higher.

Features of HDPE pipes

Features of using HDPE pipes:

  • HDPE pipes have very simple installation;
  • Corrugated pipes are suitable for laying electrical network cables;
  • If the installation is done correctly, the pipes form a tight connection;
  • HDPE pipes eventually return to their original state linear size. The use of a probe allows you to simplify cable pulling.
  • HDPE pipes have a high elasticity index (more details: " "). Therefore, they can be used all year round; changes in soil temperature will not affect them.

For laying signal or power cables, double-walled ones are optimal. corrugated pipes. Their use allows you to protect the line from any external influences.


There are two various types pipes in the manufacture of which low-density polyethylene was used: products that comply with the GOST standard, and other products from the secondary market. The second option is different worst quality. You can choose it if your budget is limited.

Advantages of low pressure polyethylene pipes:

  • Long service life (manufacturers claim 50 years);
  • No welding is required to connect individual pipes;
  • Lightweight design;
  • Over time, the product does not lose its performance characteristics;
  • External factors do not have a negative impact on HDPE pipes;
  • To lay cables in such pipes, no additional grounding is required;
  • Wide range of operating temperatures - from -25 o C to +70 o C;
  • HDPE pipes do not provide negative impact on environment, since they do not emit toxic waste or condensate;
  • Pipes made of low-pressure polyethylene are easily deformed; there is no need to use additional fasteners and connecting parts to lay the pipeline. But you should understand that if the pipe is strongly bent, the cable will not fit into it.

Types of protective pipes

What are HDPE pipes used for? They are designed to protect the cable from various influences. The soil contains chemical compounds that can harm it. Also dangerous for the cable are mechanical damage or loads and stray current.

HDPE products are divided into electrical and purely technical according to their intended purpose. The first category includes reinforced corrugated or double pipes. They have a higher degree of protection. Purely technical pipes are simpler, they are single-layer, there is no additional protection. But their price will be lower.


Corrugated pipes for laying wires are used for protection telephone lines, electricity networks and so on. It doesn't matter if it's variable or D.C. goes along the cable. But the voltage should not exceed 1 kV.

Information about the technical characteristics of pipes indicates: colors, markings, dimensions, wall thickness, number of layers, compliance with GOST. Usually for this type of product the following pattern applies: the wall thickness directly depends on the diameter of the pipe. The larger the first parameter, the larger the second.


In pipes, wall thickness can vary greatly. The minimum value of this parameter is two millimeters. In this case, the pipe diameter is in the range from 15 to 50 mm. And the maximum value is up to 3 cm. Then the pipe diameter reaches 25 cm.

Classification of pipes according to maximum pressure:

  • Light (permissible pressure - 0.25 MPa);
  • Medium-light (permissible pressure - 0.4 MPa);
  • Medium (permissible pressure - 0.6 MPa);
  • Heavy (permissible pressure - 1 MPa).

The cable marking corresponds to its performance characteristics. You can find it on the “sleeve”. This indicates the weight of the product.

Pipe markings:

  • “L” - light;
  • "SL" - medium-light;
  • "C" - average;
  • "OS" - medium-light;
  • "ST" - medium-heavy;
  • "T" - heavy.

In addition to information about the weight, which directly depends on the strength of the product, they also indicate the diameter of the pipe and the wall thickness. This necessary information for cable laying. For example, if you plan to lay a cable underground with a cross-section of up to 2 square meters. mm, then the radius of the pipe should be in the range from 8 to 12 mm.


Several cables can be laid simultaneously inside the pipe (maximum 4 pieces). If its cross section is from 6 to 8 square meters. mm, then you need to buy a pipe with a diameter in the range from 20 to 40 mm.

You need to choose a pipe taking into account the number of wires in it. For example, if you plan to install three cables with a cross-sectional area of ​​10 square meters. mm, then a pipe of the same diameter as for two cables with a cross-section of 25 square meters is suitable. mm.

Let's move on to thicker wires. For cables with a cross-section from 35 to 70 sq. mm, the optimal pipe diameter will be from 40 to 50 millimeters. It is worth considering that as the lumen width increases, the sleeve size decreases.

One more significant characteristic pipe, which determines its quality is the SDR indicator. To calculate it you need to divide external diameter products for wall thickness. The higher the value of this indicator, the lower the reliability of the pipe. Therefore, you cannot choose products with a wall that is too thin relative to its diameter. After all, it will fail faster due to low strength.

Laying technical hoses according to general principle similar to laying electrical hoses. The only differences here are the purpose and the corresponding labeling. Technical pipes made of low-density polyethylene are intended for laying non-electrical communications in the ground. For example, they can be used for heating pipes or sewerage.

For the production of technical HDPE pipes, recycled raw materials from processing are used. For example, from products marked “PE 32”, “PE 64”, “PE 80” and “PE 100”. The diameter of such pipes ranges from 2 to 50 centimeters.

Such pipes can be used not only for draining technical liquids or sewage water. They are also suitable for the implementation of drainage and reclamation systems, installation of non-pressure water supply and similar communications.

Technical pipes for cables in the ground cannot be bent or deformed, unlike corrugated products. Therefore, to create turns, connecting fittings are used: couplings, fittings and adapters. For absolute sealing, butt welding or the use of compression fittings is possible.

You can find out detailed information about the HDPE pipe from the markings. It will be possible to determine specifications products.

The principle of laying cables underground

When laying plastic pipe To lay a cable in the ground, you must follow the following steps:

  1. The first step is to check the HDPE pipes. They must not be damaged in any way. The same applies to the pulled cable.
  2. Markings must be applied to the pipe laying areas.
  3. Now you can proceed to digging a hole required sizes for cable laying.
  4. Then comes the laying of the pipe itself.
  5. And now the cable is being pulled through the pipe. It should not be stretched inside.
  6. The entire structure must be buried with a layer of sand of 10 centimeters and a layer of soil of 15 centimeters.
  7. Signaling tape can be laid on top of the embankment. You can skip this step. The tape will act as a marking.

If it fits power cable, then it is best not to use adapters and couplings at all. When this is not possible, their number should be kept to a minimum. The fact is that adapters and couplings will violate the tightness of the pipeline, which is so necessary for the power cable.


In those places where pipes emerge from the soil and enter the building, special fittings should be installed. What about minimum cross-section cable for placement underground? It's best to take not the best ones thin wires. For example, a cable with a cross-section of 4 mm or more is suitable.

If the above method of laying pipes with cable is not possible, then apply horizontal laying. Its implementation requires drilling. Among the advantages of this method are the absence of the need for earthworks. There is no need to dig a trench for communications.

To begin with, perform engineering survey. This is the name of work to study the soil characteristics in the area where construction is planned. Drilling cannot be carried out until the relevant documents have been received.

When you have the permit in hand, you can move on to the main part. It all starts with drilling a pilot well. A special drill with a radiating head is used, which easily destroys the soil. When it encounters a void, it fills with liquid. It is designed to cool the drill, and also prevents the collapse of the earth.

At the next stage, the well is expanded. To do this, put an attachment called a rimmer on the drill. Then you can proceed to tightening the pipe and wire into the well. A drilling rig is also used for this. This is the most critical stage of the work, and it is also the final one.

Laying cable in a pipe under the road

In some situations, it is necessary to lay the cable under the road. This is a rather difficult method, which is used if it is impossible to dig a trench. A specialized organization that has the necessary equipment will be able to handle the drilling.

When choosing pipes, it is necessary to take into account the load that will be placed on them. If you plan to lay the cable under the road, near houses or industrial facilities, then it is best to choose the most durable products.


You must fully follow the installation rules. In this case, the cable will be maximally protected from influences external environment, and the HDPE pipe will not wear out ahead of time.
