Product Description

Epoxy Resin Insulation Bushing of Outdoor Circuit Breaker

Product description

EP series epoxy pole, is essential part for medium and high voltage breakers. With vacuum as media, it can response in time to extinguish arc when high voltage circuit is cut off. It can be applied to indoor and outdoor vacuum circuit breakers, medium voltage switchgears, and other power transmission and distribution system. The current of vacuum interrupters can be 400A, 630A, 1250A, 2000A, 2500A, 3150a, and even 4000A. It can be applied to rated voltage of 12kv, 24kv or 36kv.

The following is some models for examples. If the dimension is not the same, pls ask for more information by contact Volcano Electrical.
