ZW32-12 outdoor high-voltage vacuum circuit breaker is an outdoor power distribution equipment with a rated voltage of 12kV and three-phase AC 50Hz. It is suitable for protection and control in power distribution systems of substations and industrial and mining enterprises, as well as places where rural power grids are frequently operated. It can also be used as power distribution,control of ring network power supply units and terminal equipment, and protection of electrical equipment. When the circuit breaker is combined with the disconnector, it can also be used as a section switch. It is mainly used to break and close the load current, overload current and short-circuit current in the power system.
Product features: no combustion and explosion hazard, maintenance-free, small size, lightweight (less than 100kg), long service life (10000 times), safe and reliable, simple operation, convenient maintenance and installation.
