ZN85-40.5 35kv 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.
