ZW32 series vacuum circuit breaker + recloser is outdoor distribution equipment with rated voltage 11kv up to 40.5kv, three phase 50HZ. It is mainly used to break and close the power system load current, overload current, shor-circuit current. It is widely used in urban power grid as a section or contact switch, or as a outdoor substation outgoing switch in rural electric power distribution system.
It consists of poles, CT, spring or permanent magnet mechanism and enclosure. Spring mechanism is sealed in the enclosure.
It has multi-protection and functions, such as overload, short circuit, quick break, earthing, reclosing, remote control and remote communication.
Operating mechanism: spring mechanism (manual/ motor ) / permanent magnet
Disconnecting switch: disconnecting at one side or both sides ( if needed)
Optional: CT, zero CT, PT, surge arrester
Control and protection: inrush current controller
Bell type FTU (optional)
Box type FTU (optional)
Installation: pole mounted
Standard
IEC 60056
