ZW32-12 12kV Outdoor High Voltage Vacuum Circuit Breaker VCB
General IntroductionZW32-12 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.Working ConditionThe

Outdoor high voltage vacuum circuit breaker is a outdoor
distribution equipment with AC 50Hz,rated voltage 12kV and
three-phase ac. It is mainly used for open circuit power
distribution network and close the load current, overload current,
short circuit current in power system.It is suitable for the
transformer substation and factory power distribution system for
protection and control use. Especially suitable for urban power
grid and rural power grids.Service conditions:1. Ambient
