How to properly stretch an electric cable between buildings

If you need to connect the building on your site to electricity (electricity is brought to the site), then there are two options. Laying of VBbShv underground armored cable in a trench. Or an overhead electric line. The first method is more expensive and not everyone agrees to it. Although convenient, no wires are visible.

To lay the cable through the air, in the villages, in the old fashioned way, they pulled a cable between buildings and hung a cable in a corrugation on it. But everything can be done in a modern way, as required by SNIPs.

You need to purchase a self-supporting insulated wire (self-supporting insulated wire), facade fastening, an anchor clip for the cable and "nuts" - fittings for self-supporting insulated wire (waterproof clips for self-supporting insulated wire and wires). It might look like this:

You can save money on the front fastening. But, you must admit, everything looks beautiful when from high-quality specially designed nodes and elements:

The cable from the building must come out in a metal hose or in a pipe. The outer part of the VVG cable should be in black corrugation (weather-resistant, as opposed to gray, which is intended for internal work).

It is not necessary to stretch the self-supporting insulated wire, there must be temperature compensation. It should sag.

The cable clamps look like this:

In general, the entire assortment will be selected for you in any electrical company. You just need to describe your task.

The types of clamps and their connection are shown in a short video:

Its cost is also low:

Of course, you can call an electrician and he will make all this installation faster. Just pay. But as you can see, the node for connecting and attaching the self-supporting insulated wire to the facade is not complicated and you can do everything yourself.
