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:
In this article we will talk about how to fix the cable channel to the wall of concrete or drywall.
Before you attach the cable , cable, you need to carefully consider the layout of the route, taking into account possible descents, ascents and turns of the laid lines.
Properly 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.).
Fastening the cable channel The choice of fasteners used for mounting the base of the channel cable is usually determined by the base material (surface) on which it is fixed . Most often, cable channels are laid on the following surfaces:
For wood surfaces, self-tapping screws on wood will be the most suitable, while special dowels-nails with a diameter of about 6-8 mm are suitable for concrete and brick foundations.
For attaching 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 (it is allowed to alternate them with wood screws). A sufficiently secure attachment is presented in this situation and dowels of the type "screwed".
The choice of fasteners for 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".
When choosing a step that should to install fasteners, it should be assumed that the more often they are located - the better. But it is also not recommended too often. Note that installing them in increments of 40-50 cm will provide By gluing the backrest you will have sufficient reliability of fastening the base of the channel cable.
An increase in the density of fasteners (step reduction) 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 case of a significant increase in this distance, the possible load on each fastening element increases, which negatively affects the reliability of the whole structure as a whole.

It is also worth noting the following: the channel must be fastened with an eye to the aesthetic side process, it does not hurt to take advantage of the construction level, with the help of which you will be able to align the laying of the bases, thereby increasing the aesthetics of the installation.
