Wires are used when laying in power networks, as well as for the installation of electrical equipment, machines, mechanisms and machines for a nominal voltage of up to 450 Volts at a frequency of 400 Hz or a constant voltage of up to 1,000 Volts. Wires are designed for use under a shed or in rooms (volumes), where temperature and humidity fluctuations do not differ significantly from those in the open air and there is relatively free access to outside air, for example, in tents, carts, trailers, metal rooms without thermal insulation.

Wires can be used as embedded elements inside complete products, the Construction of which excludes the possibility of moisture condensation on embedded elements (for example, inside electronic equipment).
