ZW32-24 outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with a rated voltage of 24kV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current and short-circuit current in the power system. It is suitable for protection and control in substations and power distribution systems of industrial and mining enterprises, as well as places where rural power grids are frequently operated.

ZW7-40.5 outdoor vacuum automatic circuit breakers is outdoor HV switching devices on three-phase AC 50Hz.lt is used for controlling and protecting 24-40.5KV transmission and distribution systems . It can be controlled to switch-on/off remotely, also be used to control energy storage and switch -on/off manually. Annexing a current transformer inside, it provides measurement and protection.

LW36-40.5(W)/T2000-31.5 outdoor sulfur hexafluoride circuit breaker is an electrical device in AC 50Hz three-phase power system, suitable for control and protection in power system with rated voltage of 40.5kV. Internal or external current transformer can be used for measurement and protection.

ZW30-40.5 series outdoor high-voltage true-pressure circuit breaker is a three-phase AC 50Hz high-voltage switchgear, mainly used for the control and protection of 40.5KV transmission and transformation systems, and can also be used for normal operation and short-circuit protection of urban and rural power grids and industrial and mining enterprises, and can be used as a connecting circuit breaker and for opening and closing capacitor banks.
