Cables control with plastic insulation screened

 

Applies to:

Cables of the brands KVVGe, AKVVGe, KVVGeng, AKVVGeng, KVVGeng-LS, AKVVGeng-LS are designed for laying in rooms, channels, tunnels in the absence of mechanical influences on the cable in an aggressive environment and the need to protect electrical circuits from the influence of electric fields.

Specifications:

1. The minimum bend radius of the cable during installation should correspond to at least 6 cable diameters.
2. The rated voltage is 0.66 kV with a frequency of up to 100 Hz or a constant voltage of up to 1000 V.
3. Resistance of cable insulation must be:
