1. VS1 12KV 11KV Vacuum Circuit Breaker

修改后8.jpg

ZN63(VS1)-12 Series Embedded Poles Type Indoor HV Vacuum Circuit Breaker, adopt solid insulation structure, use of advanced solid epoxy sealing technology, the first time, the vacuum interrupter. A leading electrical circuit. insulation and other support to become an integrated combination of solid seal pole. Successfully from a fundamental solution of the vacuum breaker gas environment, tolerance issues, make it more broad. Integrated solid-pole closure of the fluent use of a self-ventilation technology, cleverly solved the structure of solid insulation caused by heat dissipation.
