The wire is intended for electrical installations for stationary installation in lighting and power networks, as well as for the installation of electrical equipment, machinery, machines and machines for a nominal voltage of up to 450 V (for networks up to 450/750 V) with a frequency of up to 400 Hz or a constant voltage of up to 1000 V It is laid in steel pipes, hollow channels of building structures, on trays, etc., for the installation of electrical circuits. For inflexible mounting.

Typical design

Wire structure

1. Conducting vein - copper single-wire section from 1.0 to 6.0 mm 2 . The number of cores: 2 or 3. The cores are laid in parallel, in the same plane, insulated with a dividing tape base
2. The insulation of the cores is polyvinyl chloride plastic compound (PVC).
Insulation colors: white, natural or gray - B, yellow or orange - F, red or pink - K, blue or blue - C, green - Z, brown - Cz, black or purple - H.
