How to fix the cable channel

The so-called cable channels, widely used for laying various types of electrical wiring, are currently in great demand among wiring specialists. Cable channels reliably protect the laid lines from any mechanical effects and have the following advantages:

  • ease of installation, disassembly and maintenance of wiring laid in cable channels;
  • low cost of products, as well as ease of fastening;
  • high performance cable channels made on the basis of composite materials and possessing in this regard, increased resistance to fire.

In this article we will talk about how to fix the cable channel to the wall of concrete or drywall.

Preparation for installation

Before you attach the cable channel, it is necessary to carefully consider the layout of the route, taking into account possible descents, ascents and turns of the laid lines.

Competently carried out marking will allow you to choose the right size of the cable channel and decide on a set of all the necessary accessories (T-shaped joints, various angles, connectors, plugs, etc.).

The choice of fasteners used for mounting the base of the cable channel is usually determined by the base material (surface) on which it is fixed. Most often laying cable channels is carried out on the following surfaces:

  • wooden walls or walls;
  • plasterboard surfaces;
  • brick walls and partitions;
  • concrete foundations (walls or ceilings);
  • metal surfaces.

For wooden surfaces, of course, wood screws will be the most suitable screws, while special dowels-nails with a diameter of about 6-8 mm are suitable for concrete and brick foundations.

For mounting to plasterboard surfaces, you can use standard wood screws. In the case of a significant total weight of the wiring laid in the channels, it will be safer to use the butterfly dowels (in this case, it is allowed to alternate them with wood screws). A sufficiently secure attachment is presented in this situation and dowels of the type "vvirtishi".

The choice of fasteners on the metal depends on the thickness of the base; at the same time, standard self-tapping screws for metal profiles are suitable for mounting on coatings up to 2 mm thick. Very often used in this case and such a common type of attachment, as screws - "bugs".

Useful tips

When choosing a step with which fasteners should be installed, it should be assumed that the more often they are placed - the better. But it is also not recommended too often. Note that installing them in increments of 40-50 cm will provide you have sufficient reliability of fastening the base of the cable channel.

Increasing the density of fasteners (reducing pitch) is necessary in cases where the wall surfaces in the room have noticeable irregularities. In such situations (in order to avoid the formation of a large gap between the surface and the base of the channel) the gaps between fasteners should be reduced depending on the circumstances.

It goes without saying that in the case of a significant increase in this distance, the possible load on each fastening element increases, which negatively affects the reliability of the entire structure.

It is also worth noting the following: it is necessary to fasten a cable channel with an eye on the aesthetic side of the process;
