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.

Advantages
Simple structure
Adapt ultra low resistance type vacuum interrupter
Adapt optimization and modular spring operating mechanism
Suitable for occasions with frequent operation
Free maintenance and long service lif
