Description

ZW30-40.5 series outdoor high-voltage vacuum circuit breaker is a three-phase ac 50Hz high-voltage switch equipment, mainly used for the control and protection of 40.5kV power transmission and transformation system, but also for the normal operation and short-circuit protection of urban and rural power grid and industrial and mining enterprises, and can be used for connection circuit breaker and open and close capacitor bank occasions. 

The product is equipped with CT17 type spring energy storage operating mechanism, which can be used for remote control of electric energy storage, electric separation and closing operation, or for on-site manual energy storage, manual separation and closing operation.
