КВБбШвзнг(А) (KVBbShvzng(A))

SCOPE AND PURPOSE

The cables are designed for fixed connection to electrical devices and equipment, to assemblies of clamps of electrical switch gear with the nominal alternating voltage up to 660V of frequency up to 100 Hz or direct voltage up to 1000V for installation in the premises, conduits, tunnels, in conditions of aggressive environment, in the absence of mechanical effects on cable.

It is possible to lay the cable in the ground (trenches) where the places of the exit of the cable from the ground to the surface are protected. The cables are used for installation in cable structures and spaces for providing of fire safety.

The class of fire hazard of the cables according to GOST 31565 01.8.2.5.4.
