Recommendations for laying electrical wiring in pipes

metal Advantage of this version of

The advantage of conducting wiring on metal and PVC pipes is as follows:

1. Wiring is reliably protected against mechanical damage and unfavorable weather conditions( if the electricity network is installed outdoors).
2. If necessary, you can easily replace the wiring in the apartment, carefully pulling out the cable and passing the new conductor along the already finished track. In addition, in this case, it will not be necessary to damage the finish of the walls for replacement.
3. All electrical safety standards will be observed in wooden houses. Immediately it should be noted that according to the rules of the electrical installation when installing the cable through a wooden wall, it is necessary to protect the conductor with a metal pipe or a sleeve.
4. When carrying out the electric network underground, the wiring will be protected from rodents - in particular moles, which very often bite the insulation and damage the line.
5. In humid rooms, when installing wiring in pipes, the line will be reliably protected from moisture, and in dusty rooms that are too dust-free.

As you can see, this method of wiring is necessary only if you have non-standard conditions. All this is done only for reasons of electrical and fire safety.

How to make wiring?

In fact, most conduct wiring in the pipes is not difficult, you just need to make the appropriate trunk and run the cable into it. The technology of installation, in fact, as well as the conditions for the use of plastic or iron pipes has its own characteristics, which we will now talk about in more detail.

In plastic

Plastic pipes are recommended to be used for electrical work on surfaces with an open method, as well as in a concrete floor screed( as in the photo at the beginning of the article).

Cable laying technology consists of the following steps:

• According to the electrical scheme, the walls or the floor are marked with a marker.
• After every 50 - 90 cm the main line is fixed to the surface with clips or staples.
• The cable is pulled in by means of special broaches - nylon or steel( wire).
• Pipes are connected to junction boxes( connection points of wires) and to each other with a special soldering iron.
• If the installation is in the floor, a concrete screed is poured over the finished track. By the way, immediately it should be noted that with a horizontal laying of the trunk, you need to arrange a slight bias towards the distribution boxes to drain the condensate.

The requirements for electrical work are as follows:

1. It is strictly forbidden to connect electrical wires in pipes. All connections must be exclusively in junction boxes, which does not violate the rules of TB.
2. Do not bend the track more than 90 degrees. Otherwise, you will not be able to change the cable;he will be caught in a corner.
3. When installing wiring in damp and flammable rooms, it is necessary to seal the connection place of the elements, the junction with the junction box, and also to make a hermetic entry.
4. In the floor and brick walls it is better to use smooth HDPE tubes.
5. The minimum cross-section of the wire that will be held inside must be at least 1 mm.kv according to the rules of GOST.

In this case, you can use PVC / HDPE pipes, as well as corrugated - DSC, which are often used for wiring installation under plasterboard.

In metal

An alternative solution is the use of metal( both galvanized and iron) pipes for the installation of concealed wiring. This option is preferable if the cable should be laid in the ground or a wooden surface, for example, when installing electrical wiring in a bath.

The instruction for laying the line with your own hands looks like this:

• As in the previous case, the pipes are laid according to the created drawing.
• To connect the elements, a welding machine or a thread on both sides is used.
• Grounding of metal structures, as well as organization of incline towards the junction box, is to be made.
• The surface of the protective elements is painted to prevent corrosion.
• The cable is pulled in by a nylon pull or metal wire.
• The mains are fixed every 50-90 cm using metal staples.

1. If you decide to conduct a hidden wiring in the floor, then do not paint the metal parts, becausethis will worsen the adhesion of the concrete solution to the metal.
2. As for the bend, the connection of the wires, the sealing of the joints and the minimum cross-section of the wires, everything remains the same here as in the previous version.
3. In order not to damage the insulation of the wiring at the point of its exit to the surface, the ends of the steel tubes need to be terminated with bushings.
4. For fast disassembly of the main line, it is recommended to avoid welding joints, replacing them with threaded connections.
5. If the room is dry and free of dust, you can do without additional sealing at the junction of the sections.

That's the whole technology of laying electrical wiring in the pipes with your own hands. As you can see, there is nothing complicated, it is important to take into account all the advice and act strictly on the basis of the provided editing technology. By the way, pipes can also be used to make a retrofit in the house. This option proved itself very original, which you can see by looking at the picture showing the open wiring in old pipes:
