Laying cables in the ground in pipes: the basic rules of work

Furnished summer cottage, the owners should solve many of the operational aspects associated with new construction. To comfortably live in a country house, you will need to consider the quality of the system water, sewer, and electricity. Laying cables in the ground in pipes necessary for the supply of lighting fixtures, heaters and other household appliances. To self-perform this work, it is necessary to study the technology of its implementation. This will allow you to create high-quality and durable system.

General requirements:

Not every owner is satisfied with the air carrying system cables to the house. Increasingly gaining momentum underground option of laying power supply lines. They enter the house through the basement. So such a type of work performed at the stage of laying the Foundation.

The Plan of such electrification is developed before the start of construction. Thinking through all the ramifications of the cable. At this stage takes into account the state of soil, type of climate zone and other aspects of safety of operation of the system.

Laying cables in the ground in pipes must account for existing requirements and regulations. When carrying out these works it is necessary to take into account the norms SNiP and PUE as well as GOST. Performing all necessary installation operation, be sure to follow the rules of safety.

Types of materials

Laying cables in the ground in pipes (PUE, SNiP clearly reglamentary this process) requires selection of the correct materials. First and foremost, they must be safe. But the cost of them should be acceptable. Today, there are communications that do not need to hold them on the pipes. This armored cables. However, their cost is very high. So the trench method of installation involves the use of a cheaper cable in special tubes.

The Cable, which runs underground, shall be marked m & as. This variety allows to apply all existing regulations. However, it is definitely mounted trenching in the pipe. The route can be metal or plastic.

Pipe PVC/HDPE made of plastic. They are quite durable and have smooth surface. Gofrotruba type DKC is allowed to use only for the interior, for communication under a layer of plaster.

Advantages

The Laying of cables in ground in HDPE pipes, metal or plastic varieties, has several advantages. This is to protect the wire from weather, mechanical damage.

If you need one to replace the Explorer, it's easy to get the old cable and existing track to put the new. This technique allows you to comply with fire safety regulations. This is especially important in wooden houses. Pipe for trench installation, prevents the occurrence of sparks and overheating of surrounding materials.

The Advantage of this system is the additional protection of the cable. Thanks to the tube it will not harm rodents, microorganisms. If the conductor is laid in the ground without such protection, the moles can be cut.

Construction of the trench

Laying cables in the ground in pipes (photo provided below) must meet certain mandatory requirements. The depth of the conduit in the ground shall be not less than 70 cm, This figure varies depending on the climate zone.

It is Impossible to conduct the course under the Foundation. From him the cable should go no closer than 60 cm Width of gutter is selected in accordance with the number of conductors passing on the highway. They should be located not closer than 10 cm from each other.

The Trench is filled with sand and compacted to the level of 15 cm Before the arrangement of the track you should consider the site plan. Not allowed to tube with electrical conductors held closer than 1 m from a gas or 2 m from water supply systems.

If to strengthen the transmission lines used brick (with a significant subsidence of the ground), it should not be hollow. On top of the track you want to build a ribbon with the inscription on the passage of the power cable. Then again poured a layer of sand and land with a slide.

Features of tabs in plastic tubes

The Laying of cables in ground in HDPE pipe has a number of features. They need to learn before working. Initially it is necessary to perform the drawing of the track. Fastening the pipe to produce intervals of 60-80 cm To do this, use a special bracket or clip.

To push the cable through the pipe, using a special broach or a metal wire. All elements of the course connect with a special soldering iron. Cable inside to connect to be using special couplings.

If this track has a vertical layout, it is done with bias. So it won't gather condensation.

Features of tabs in metal pipe

Pulling conduit is required in wooden building bath, it is better to give preference to a metal tube. It is a strong product. It can begalvanized or iron.

It Should be noted that the laying of cables in ground in pipes DKC invalid. They are used purely for cable laying inside premises. To connect the metal elements of the track, you can use weld or threaded fittings.

When building a system, you must perform the grounding. The bias should run in the direction of the junction box. Tubes and joints is required to be painted to avoid corrosion. For the interior, such design is better not to use. You fill the floor with concrete painted surfaces will not mate.

Connection Rules

Laying cables in pipes in the ground rules which reglamentary, SAE and GOST should be carried out responsibly. Do not make connections in the pipes. Do it only in the most extreme cases, and it uses a special clutch. It is Better that such wiring connections in the junction boxes. This is required by safety rules.

The Track can not be curved at an angle more than 90 degrees. Otherwise, replace the old conductor will be impossible to meet. The connection of the pipes must be additionally sealed. Enter should be sealed.

Conductor cross-Section must be selected in accordance with the load of the system. It is better to give preference to cable made of copper. Aluminum conductors are only applicable for internal works.

Expert advice

Correct routing of the cables in the ground in pipes to do on your own is quite simple. However, it is necessary to take into account the expert advice. They recommend the use of the track, the width of which is more 3 times than the conductor.

If the winter in this climate zone is very severe, the ground can freeze more than 70 cm Below the tubes are not deformed, they should be carefully attached. But it is better if the track will be even deeper.

In developing the plan it is necessary to avoid laying a trench under areas of the car Park, a Playground or garden paths.

Familiarized with this technology as laying cables in the ground in pipes, it is possible to do this yourself. Observing all requirements of building codes and safety rules, you can create high-quality, durable track. Its operation is safe.
