Description

Product Standard: VIB type vacuum circuit breaker conforms to national standard GB********3 <<HV Vacuum Circuit Breaker>>, DL/T*******0<<Order technical condition of *2kV~*0.5kV Vacuum Circuit Breaker>> and some stipulation of IEC********0:***1<<HV AC Vacuum Circuit Breaker>> Technical characteristics: The vacuum interrupters of VIB type vacuum circuit breaker are used embedded poles by advance APG technology; the primary conducting part is capsulated into an integrated unit by using epoxy resin which makes the insulation condition of primary conducting parts against from impact by exterior environment, it can effectively prevent moisture, filths and the damage to the insulation property due to condensed water. The vacuum interrupter is vertically installed in an insulation house which is made up of epoxy resin cast by advanced APG technology; this kind of structure can maximally reduce the dust accumulation on the surface of vacuum interrupters which ensure the high resistance state even if under the damp, hot and serious filthy environment. The VIB type vacuum circuit breaker uses specialized vacuum interrupter with advanced material and design for their contact, it is with strong breaking capability and high reliability and performed the type test for its electrical life under the condition of auto re-close at class E2 level (the breaking operations reaches **4 times for different short-circuit currents) as per national standard, it is more accordance with the actual usage requirement and realized free of maintenance for its primary part.
