VD4 (S) -12 intelligent sealed vacuum circuit breaker with intelligent online monitoring function, can be real-time monitoring of the circuit breaker in the running state, give out the alarm signal and to the remote transmission when the fault comes. At the same time, the product is equipped with perfect mechanical and electrical interlock to ensure the safety in the process of operation and inspection. Product design, manufacturing, installation, service systems strictly implement ISO9001, 2000
VD4 (P) -12 type sealed high-voltage vacuum circuit breaker independently developed by our company is the leading domestic level of a new generation of 12kV vacuum circuit breaker .Its main feature is that the main circuit adopts the solid insulation solid sealed pole, which uses a special embedded technology, to pour the epoxy resin into vacuum interrupter with ultra low resistance and conductive parts, so as to realize the solid insulation of main circuit. The operating mechanism is new-type s
