Types of cable channels for electrical wiring: Instruction + Video Types of cable channels for wiring. Every normal office, home or industrial area has regular wiring. As a rule, such wires are laid during construction into the ceiling or furrow, which will then be sealed. But there is another way to lay a hidden wire, while everything will be done without noise and dust. For example, you decide to make repairs or lay an electrical wire from one room to another over the ceiling or wall, and so that old parents or a child who has just learned to walk do not stumble about it.

This will help various types of cable channels for electrical wiring.

If necessary, the wire can always be enough, supplement or completely replace the wiring ... By the way, the installation of cable channels is extremely simple, but everything is in order.

Typically, any modern building has a variety of cables and wires. If they were left lying along the wall or on the floor, then they would greatly interfere with the movement of people, or at least spoil the interior, and also pose a real threat of electric shock (in particular, if the wire is electric).

The cable channel solves this problem. Do not confuse them with metal boxes, which are not as flexible or as aesthetically pleasing. Plastic cable duct for electrical wiring is flexible and aesthetic, gives safety and does not spoil the interior.

The lid easily snaps onto the box, into which the wires will be placed. The wires that can be laid in the channel can be power electrical, telephone cables, information communication cables and others, that is, any wire that is used indoors.

General information


At the moment, there are the best manufacturers of products from the field of electrical engineering ( for example, IEK, Legrand or DKS), in the assortment of which there are such types of plastic boxes for electrical wiring:

  • Mini cable channels (minichannels). Most often they are used in order to lay television, computer and telephone wires.Due to their compact size, they practically do not spoil the interior in the room.

  • Floor-standing (differ in the oval shape of the box). They are the most comfortable of all, as they do not impede movement due to their oval shape.
  • Skirting boards. as a rule, they are used in apartments and houses, since they allow you to completely hide the cable in a special channel of an electrical type skirting board.
  • Trunk.

  • Types of cable channels for electrical wiring: Instruction + Video Halogen-free . In this case, there are no halogens in the box material - fluorine, bromine, astatine, chlorine and iodine. Such a product is considered environmentally friendly, and its use is extremely important in a closed room.
  • Perforated . Due to the design feature, such a box has less weight, and therefore the final cost.

    Of the advantages, it is worth noting the ease of fastening the cable channel.

  • Parapet . The most popular type, which is most often used for laying wires in offices, houses and administrative buildings.
  • Corner . This type of cable duct is recommended to use in order to lay electrical wiring under the ceiling.

  • Flexible . Due to the perforated shape, it can be used to fix the cable even on uneven surfaces. They are rectangular and round in shape.
  • Transparent . They were able to prove themselves well when creating LED strip backlighting.

    Due to its full transparency and compact size, using such a cable, you can effortlessly fix the LED tape on the ceiling, as well as on the wall or even the underside of the car.

  • Staircase . They are used for laying heavy cables, that is, they have a reinforced structure.
  • Wirewound . The cheapest option for a cable and at the same time the most convenient option for cleaning.

    On boxes made of wire made of steel, almost no dust settles, and this is very practical if you need to conduct wiring in technical rooms or warehouses. An additional advantage of the transparent tray is that it is well ventilated, due to which the cable line does not warm up much.

  • Special boxes for air conditioners .

These are the most popular types of cable ducts for electrical wiring, which can be used in administrative, industrial and residential premises.


PVC products are sold in standard cuts, each of them is 2 meters in length, but the dimensions are in plan sections are different - from 1.

2 * 1. 2 cm to 10 * 6 cm and various intermediate dimensions (7 * 2, 8 * 4, 4 * 4 and others). The shape will also be determined by the type of product, for example, the corner channels will have a triangular section. The size will be selected depending on how thick the wire is. With the dimensions, everything is quite simple, and the assortment can be viewed in the manufacturer's specialized table.

Note that some manufacturers have other sizes of cable ducts, for example, 8 * 4. 5 cm.The most popular size is 1.2 * 1. 2 cm (for laying the communication cable), as well as 4 * 4 and 10 * 6 cm.

For corner trays, the most practical section is 4 * 4 cm.To choose the right plastic product, you need to decide what size the box should have. Everything should be done so that the wires are laid loosely in its container and a small margin remains, which may be useful in the future. Consider also the fact that the main channel, which will stretch along the entire ceiling, is better to be made larger, and the box for vertical type branches to sockets and switches is smaller.

After that, it is required to make calculations and determine how much channel is required for installation.

The length should be calculated with a margin of 20%, since there is a possibility that some part of the box will be damaged during operation, and it will not be possible to buy exactly the same cable channel. You can choose a box for laying wires of any color, but remember that white products are the most common. To calculate the minimum size of the channel cable, you need to know the number of wires and the cross section, which will help a special table.

Selection of fittings

Many manufacturers of plastic boxes produce in addition various fittings, for example:

  • Types of cable channels for electrical wiring: Instruction + Video Plugs.
  • Joints.

  • Tees.
  • Internal and external corners.
  • Angle adapters.

Even if you save on the cost of the box, it is better not to waste time on trifles with various supplement elements and not to buy a cable channel without the required accessories. Believe me, installation work with it is much easier, and the finished product will look much prettier.


The most popular case material is PVC, and this material was not chosen by chance. The first is that it is inexpensive, the second is quite durable, and the third is that it is a dielectric, while the material does not care about rodents. During installation work, the channel can be easily cut with a conventional cutter to the required length, and it bends well if you need it. The size and type will be matched to any number of wires, and the color to the overall design of the room.

At the moment it is possible to make an order for any color of the box that suits the interior.

White is perfect for an office, and a wood-like box is perfect for a country house or apartment. There are more than a dozen color schemes for just one "tree", ranging from the most common (beech, oak, pine) to such as walnut, red cherry and northern oak.

It is necessary to calculate the volume of the cable channel for electrical wiring with a margin so that the wires have a little room, and also choose the appropriate color and length. Try to provide a headroom as there is a possibility that additional wires will be needed in the future. Fittings such as docking adapters, plugs and tees should be in the plan even before purchasing the material.

The very last step is to check how easily and firmly the channel snaps into place.

Installation work

Believe me, the installation of the channel cable will not be a hassle. If your walls, floor and ceilings are even, then there will be nothing easier than gluing the channel on top of the cladding, while cutting off a piece of the required length in advance using a grinder or a knife.

If desired, the box can be glued to liquid nails or other good quality glue. There is one more mounting option - with screws.

Dowels are suitable for concrete, and when the base of the channel is installed (if glue was used, then when it dries completely), all that remains is to lay the wires and close everything with a lid. Make sure the joints are almost invisible.
