High voltage 12kV Vacuum circuit breaker

Indoor vacuum circuit breaker with nylon tube
Indoor switchgear type VS1 vacuum circuit breaker is applicable to 12kv power system, as a protection and control unit of power equipment, industrial and mining enterprises, it can be used for switching loads of various kinds and frequent operation, repeatedly breaking short-circuit current situation. The product adopts new type of circuit breaker, a VS1 part can adopt the international brand of embedded pole, the vacuum interrupter and the main circuit part is fixedly sealed into a whole, protect the interrupter from collision, dust and gel image, strong ability to adapt to the environment, greatly reduces the cost of operation and maintenance. The real implementation of the product part of a maintenance free, low maintenance operation mechanism; operating mechanism and circuit breaker body design, after type test, E2 level, M2 level of mechanical electrical life.

Product Standard:
VS1 type vacuum circuit breaker conforms to national standard GB1984-2003 HV Vacuum Circuit Breaker, JB3855-1996<3.6-40.5kV indoor AC high voltage vacuum circuit breaker>, DL/T403-2000<12kv-40.5kv HV vacuum circuit breaker ordering technical conditions>, and IEC62271-100:2001 high voltage AC circuit breaker relevant regulations.
