China Wholesale Medium Voltage Load Switch Manufacturers – VSG/C-24KV-200/280 Indoor High Voltage Side Mounted Vacuum Circuit Breaker – Timetric Detail:
VSG/C-24KV indoor high voltage vacuum circuit breaker for switchgear 24kV
Indoor switchgear type VSG vacuum circuit breaker is applicable to 24kv 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 VSG 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.
