КВБбШвнг(А)-FRХЛ (KVBbShvng(A)-FRKhL) Russian analogue of NYBY Super Cold Resistance Flame Retardant
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 are used at group installation of cable lines in cable structures, outdoor (open-air) electric units (cable racks and galleries) and they are designed for operation at ambient low temperature from minus 600C to plus 500C.
For manufacturing of the cables the materials which provide resistance of the cables to the impact of ambient low temperature are used, with the possibility of laying of the cable without preheat at temperature up to minus 300C.
The cables are fire resistant. They save capacity for work under the influence of fire for 180 minutes.
The armored cables are used in case of danger of mechanic damage in process of operation, if the cable is not exposed to significant tensile force.
The class of fire hazard of the cables according to GOST 31565 П1б.220.127.116.11.
Copper, single-wire, of the 1 class according to GOST 22483, with the cross-section from 0.75 to 6 mm2.
Lapping with fiber-glass mica tapes.
PVC-compound of low flammability.
From 4 to 127 insulated conductors.
The insulated conductors are twisted; there is a marker pair in each layer.
It is allowed digital and color coded marking of the conductors.
In the waterproof cables the insulated conductors are twisted with the water blocking elements.
It is laid helically with two steel, galvanized tapes.
Cable sheath or jacket
PVC-compound of low flammability
