Describe Display

ZW32-36.2kV is a three-phase AC outdoor vacuum circuit breaker with automatic recloser function, designed for 10–35kV power distribution networks. It adopts vacuum arc interruption and solid insulation technology, integrating vacuum interrupter, voltage/current sensors, and control modules. It is suitable for breaking and making load, overload, and short-circuit currents.

 

This recloser supports smart grid applications. It can identify transient and permanent faults, isolate faulty sections, and restore power to healthy areas, enabling automated fault handling and minimizing outage areas. It can communicate with the central master station via GPRS, fiber optic, and other protocols.
