Features of the installation of snowmobile systems

The modern building materials market offers thermal cables both in the form of sections collected and ready to install (the section is a segment of the cable, which have a fixed length and clutch with the conductors with which it is connected to the power grid) and the form of bays). The finished sections are best mounted on the roofs of standard performance, but the cables in the bays are best used if the roof of the house has complex and non -standard architecture.

The power of the resistive thermal cable is 20-30 W/m, self -regulating an order of magnitude higher – from 25 to 60 W/m. You can connect such a system as to the KVGE cable, since any other, suitable for the method of use and power. If the snowmobile system is planned to be installed on the roof of the house, which is made of soft coating (roofing material or gont), then the power of the cable must be limited to 20 W/m, in order to avoid its thermal damage. Often, in order to provide the necessary power in gutters and yndovs, two cables are laid at the same time. If the pipes of the drainage system have a large diameter, the number of parallel thermal cables may increase.

All thermal cables that go on the sunny side should have an increased level of resistance to ultraviolet rays. Power cables that are used to connect to the mains, must be placed in an atmospheric metal sleeve. It protects the cable from various mechanical damage, which are possible during installation and regular inspection and repair of the roof. Additionally, to protect the inhabitants of the house from current damage, the snowmobile system must be equipped with protective shutdown devices that will turn off the snowmobile system in case of insulation and the occurrence of electricity leakage.
