ZW32-12 outdoor high voltage vacuum circuit breaker

ZW32-12 type outdoor H.V. vacuum circuit breaker is the outdoor distribution equipment with rated voltage 12KV, three phase AC 50Hz. It is used in substation and industrial and mining enterprises distribution system for protecting and controlling use. It is also used in rural power grid places with frequent operation for breaking and closing the load current and over load current and short circuit current of power system.

The out insulation of the vacuum interrupter adopt silicone rubber casing, with longer life, higher reliability, good weather resistance, convenient for transportation, good rating. The operating mechanism adopt miniaturization, high reliable spring operation mechanism, has the advantages of simple structure, mechanical life up to 10000 times.This circuit breaker and controller can form a complete set as recloser, realize remote control, telemetry, remote communication, remote adjustment four remote function. Product features: no combustion and explosion hazards, maintenance free, small size, light weight (less than 100kg), long service life (million), safety and reliability, simple operation, convenient maintenance and installation.
