ZW32-40.5
ZW32-40.5kV、35kV、33kV Outdoor Vacuum Circuit Breaker （ZW32-40.5F、ZW32-40.5、ZW32-40.5G） adopts a uniquely designed one-piece solid-sealed pole and a highly reliable operating machine structure. The device is mainly used in medium-voltage overhead line power grids for dividing and combining load current, overload current and short-circuit current.
The upper vacuum circuit breaker is a new 35KV outdoor high-voltage vacuum circuit breaker that replaces the ZW7 vacuum circuit breaker. ZW32 is the miniaturization of ZW7, which is safer and more stable. ZW32-40.5 can also use permanent magnet operating mechanism, cooperate with automation equipment, GPRS, GSM and other remote communication functions to achieve four remote functions such as remote signaling, remote measurement, remote adjustment, and remote control.
