KyVVng(A)-LS

Low fire hazard cables for electric units at voltage up to 300/500 V.

CONSTRUCTION: 

1. Electric conductor: - copper single or multiwire 1 or 2 grade acc. to GOST 22483 for cable KyVVng(A)-LS - copper multiwire 5 grade acc. to GOST 22483 for cable KyGVVng(A)-LS 

2. Insulation – from low fire hazard PVC compound. Core conductor – insulated conductors twisted between each other. Insulated conductors of multiwire cables have distinct colouring. Neutral conductor insulation has blue colour. Ground insulation conductor has two colouring (green-yellow). Inner core conductor space from insulated conductors filled with harness, pressed from low fire hazard PVC compound. 

3. Outer sheath – from low fire hazard PVC compound.

Cables with copper conductors with insulation and sheath from low fire hazard PVC compound KyGVVng(A)-LS and KyVVng(A)-LS used for electric units at stationary laying in lightning and power networks, as well as for assembly of electric equipment, machinery, rigs, inner electric units at nominal alternating voltage up to 300/500 V inclusive, nominal frequency up to 400 Hz. 

Wires used for general purpose application at deliveries to the internal market and export. 

Wires used for bunched laying cable lines in buildings of inner (closed) electric units, for electric wiring in apartments and public places.
