Product Description

1.  ZW7 40.5kv 33kv 35kv 40.5kv outdoor high voltage vacuum circuit breaker vcb


ZW7-40.5 series outdoor high voltage vacuum circuit breaker is three phase AC 50Hz, rated voltage is 40.5kV outdoor high-voltage electrical equipment , attached the spring operator or electromagnetic actuator can be well controlled electric opening and closing can also be Manual storage, manually open and close. Design performance meet GB1984-89<<AC high voltage circuit breakers>>; national standards, and meet the IEC-56<<high-voltage AC circuit breakers>>; International Electro-technical Commission standards. ZW7-40.5 Type vacuum circuit breaker is mainly used for outdoor 35kV power transmission system control and protection also applies to urban and rural power distribution networks and industrial and mining enterprises in the normal operation and short circuit protection purposes. The overall structure of the insulator pillar product type; built vacuum interrupter type on the vase, porcelain vase for the next pillar vase. For frequent operation place. And has good sealing, anti-aging, high pressure, no burning, no explosion, long life, convenient installation and maintenance features.
