КВВГ (NYY)

General information

Control cables of these brands are used in stationary electric and alternate current devices with a nominal voltage of 660V or in direct current electric distribution devices with a nominal voltage up to 1000V, in closed areas, channels and tunnels, aggressive climatic conditions and in places that are not exposed to external mechanical influence.

Control cables of these brands are used in stationary 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. 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.

Construction design:

  1. The power core made of copper and aluminum wire
  2. PVC insulation or flame retardant PVC with low smoke and gas emission
  3. Belt insulation from PET tape
  4. PVC jacket or flame retardant PVC with low smoke and gas emission
