Product Detail

1. Factory made ZW32-12KV 11KV 630A 1000A 1250A Outdoor Vacuum Interrupter


ZW32-12 type outdoor high voltage vacuum circuit breaker is three-phase AC,50(60) Hz outdoor power distributio equipmentwith the rated voltage of 12kV.It is mainly used to break and close the load current,and short circuit current in the electric power system.It fits to be used to protect and control the circuit in substation,mining and industrial enterprises.

It can be used in the frequently operation places such as the rural power network. The product is accordance with GB1984-2003 standard.
