Overview
For epoxy poles, Main technical data are as following: rated voltage ranging from 12KV to 40.5KV; rated current ranging from 630A to 4000A; rated short time breaking current ranging from 16KA to 50KA.
Product Details
Product description
The Embedded pole is to embed the vacuum interruptor and circuit-breaker related conductive parts into the easy-curing solid insulating material such as epoxy resin or thermoplastic material to form the pole at the same time. The circuit breaker pole becomes an integral part.
