Product Description

ZW8-12KV ZW8-12 VCB HV Intelligent Reclosing Remote Control Outdoor Vacuum Circuit Breaker



ZW8-12 adopts vacuum interrupter, air insulation and electric spring operating mechanism, which makes the product have strong arc extinguishing ability, high number of short circuit breaking, no fire and explosion hazard, convenient operation and excellent performance. A more practical product.

The overall structure of the product adopts three-phase common box type, the casing enters and exits the line, and the inside of the box is dry coal air. The electric spring operating mechanism is arranged on the side of the box body, which can be used reliably under harsh environmental conditions.

The vacuum interrupter of this product adopts ceramic shell, cup-shaped longitudinal magnetic field contact structure and copper-chromium contact material, which has excellent breaking and closing short-circuit current capability.

The product is small in size, light in weight and beautiful in appearance. The vacuum interrupter and the insulated support sleeve are compact in design, and the outgoing conductive rod is externally coated with silicone rubber to adapt to harsh weather conditions and dirty environments.



ZW8-12/630-20 outdoor high voltage vacuum circuit breaker is an AC 50Hz three-phase power system. It is mainly used to break and close the load current, no-load current and short-circuit current of 10Kv power grid in urban areas. It can also be used as rural power grid. And the sub-switch of the small power system is a replacement product of the city network and the agricultural network without oil.
