Product Details

1.ZN39-40.5KV 36KV 33KV indoor Handcart Type Vacumm Circuit Breaker/ circuit recloser

ZN39-40.5 type indoor high voltage vacuum circuit breaker series, series of three-phase ac 50 hz, rated voltage 40.5 kV indoor high-voltage power distribution equipment. With JYN1-35, the GBC - 35 switchgear systems. 

The products comply with GB1984 "ac high voltage circuit breaker". 

 circuit breaker adopts the air circuit breaker under the condition of meet the normal operation of the air distance and the creepage distance requirements, 

Overall it is reasonable, the structure is stable, adjustment is convenient. Operators use electromagnetic mechanical machinery CT19N CD10 - III or spring. 

Circuit breaker has a set of interlocking device, with the switch cabinet, using force machinery atresia, satisfies the requirement of switchgear "five prevention" function.
