ZW32-12GG 12kV Outdoor Intelligent Dual Power Switchgear

Smart Switching for Overhead Power Distribution

The ZW32-12GG is an intelligent outdoor vacuum circuit breaker designed to automatically detect and switch between two power sources in 12kV distribution networks. Integrated with a smart controller and dual-sensor logic, it ensures uninterrupted power flow during faults or line maintenance—ideal for rural grids, industrial feeders, and mining zones.

Unlike traditional outdoor breakers, the ZW32-12GG excels in real-time fault detection, auto reclosing, and remote communication, supporting SCADA integration via RS485 or wireless modules.
