КВБбШв (KVBbShv) - Russian analogue of NYBY
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.
The cables of type KVBbShv are used for installation in the premises, conduits, tunnels, in conditions of aggressive environment and in areas exposed to stray currents, if the cable was not subjected to significant tensile force.
The class of fire hazard of the cables according to GOST 31565 01.8.2.5.4.
STRUCTURE
Conductor
Copper, single-wire, of the 1 class according to GOST 22483, with the cross-section from 0.75 to 6 mm2.
Insulation
PVC-compound.
Core arrangement
From 4 to 61 insulated conductors.
The insulated conductors are twisted, there is a marker pair in each layer.
Separating layer
PVC-compound or a layer with the PET tape.
Cable armoring
For cables of types KVBbShv is laid helically with two steel, galvanized tapes.
Over sheath or jacket
PVC-compound.
