POLE-MOUNTED SWITCH

Common-Box Type Pole-Mounted Switch

The HZW□-12 intelligent pole-mounted switch is an integrated smart distribution device designed for overhead lines in power distribution networks. It combines the switch body, current/voltage transformers or sensors, Feeder Terminal Unit (FTU), and primary/secondary connection cables into a single unit. Primarily used to break and close load current, overload current, and short-circuit current in power systems, it provides control and protection functions. This switch enables data acquisition, fault processing, communication, time synchronization and location, waveform recording, and feeder automation capabilities.
