Our new generation ZW32 type recloser is developed by ourselves. It is a combination of advanced domestic and foreign technology. It embodies our ideas: intelligent, environt-friendly, energy-efficient and maitenance-free. It is a kind of outdoor three phase distribution equipment with 24kv rated voltage, 50/60 Hz frequency. It is mainly used to break, make the load current, overload current and short circuit current in power distribution system. It is used as protecting and controlling equipments in transformer substation, industrial and mining enterprises power distribution system. It is especially suitable for rural power network, places with frequent operation, city and rural power network renewal. ZW32 series outdoor automatic recloser combines the functions of control, protect, measurement, communication, reclosing and recording.
