КВБбШв (NYBY)
General information
Control cables of these brands are used for stationary laying in electric and alternate current devices with a nominal voltage of 660 V or in direct current electric distribution devices with a nominal voltage up to 1000 V, in closed areas, channels and tunnels, aggressive climatic conditions and in places that are not exposed to external mechanical influence, and also for the purpose of protection from the external electromagnetic field.

Control cables of these brands are used for stationary laying in electric and alternate current devices with a nominal voltage of 660 V or in direct current electric distribution devices with a nominal voltage up to 1000 V, in closed areas, channels and tunnels, aggressive climatic conditions and in places that are not exposed to external mechanical influence, and also for the purpose of protection from the external electromagnetic field.
The cores forming the cable get twisted in layers. Two cores in each layer should differ in color between themselves and other cores or must be numbered.
Structural design:
- The power core made of copper and aluminum wire
- PVC insulation or flame retardant PVC with low smoke and gas evolution
- Belt insulation from PVC emission
- Armor made of two galvanized steel tapes
- PVC jacket or flame retardant PVC with low smoke and gas emission
