The product is small in size, light in weight and beautiful in appearance. Compact design of vacuum interrupter and insulating support sleeve, silicone rubber injected outside the conductive rod, which can adapt to the harsh climate conditions and dirty environment.
The overall structure of this product adopts three-phase common box type, casing in and out of the line, the box for the dry coal air, electric spring actuator is arranged in the side of the box, can be used reliably in the more severe environmental conditions.
This product vacuum interrupter adopts ceramic shell, cup-shaped longitudinal magnetic field contact structure, copper chrome contact material, with excellent opening and closing short-circuit current ability.
ZW8-12/630-25 outdoor high-voltage vacuum circuit breaker system AC 50Hz three-phase power system, mainly used to open and close the city downtown 10kV power grid load current, no-load current and short-circuit current, but also can be done in rural power grids and small power systems sub-switching, is the city network, the farm network oil-free modernization products.
