CB-10KV 200A-1500A Indoor Copper Conductor Wall Bushing

The CB-10kV Indoor Copper Conductor Wall Bushing is designed for power stations, substations, switchgear, and electrical distribution systems operating at rated voltages up to 10kV.

It provides reliable insulation and mechanical support for copper conductors passing through walls, partitions, and metal enclosures while maintaining electrical isolation from grounded structures.

Indoor copper conductor wall bushings are commonly used in medium-voltage power distribution equipment and switchgear installations.
