Overview

      ZW32-12 outdoor high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is outdoor distribution equipment with rated voltage of 12kV and three-phase AC of 50Hz. It is mainly used to open and close load current, overload current and short circuit current in power system. It is suitable for the protection and control in the power distribution system of substation and industrial and mining enterprises, as well as the places where the rural power grid is frequently operated. The circuit breaker has the characteristics of small volume,  lightweight, anti-condensation, free maintenance and so on. It can adapt to the harsh weather conditions and a dirty environments.WHY CHOOSE US

    Each vacuum tube will have a factory number. After thevacuum tube is produced and stored for 8-12 months, it willbe tested whether there is air leakage and whether thepressure resistance passes the market. Most manufacturerssell it now and will not carry out secondary testing


     The vacuum tube used in zhegui vacuum circuit breakerhas been tested for the second time, and the third time willbe tested after installing the vacuum circuit breaker, so youcan buy it at ease

Vacuum Tuoe Details

    All transformers of this product are made of pure red copper, while ordinaryones are made of copper-clad aluminum. Direct use of copper-cladaluminum is easy to cause great potential safety hazards

Copper isolating knife

    The components used in the vacuum circuit breaker are made of real materials. The thickness of the isolation knife is as high as 2.8mm.The ordinary isolation knife is only 2.0mm. Even various operating handles are made of high-quality materials
