Outdoor Pole-Mounted Switchgear
ZW32-12, ZW20-12 and ZW68-12 series 10kV outdoor pole-mounted switches are applicable to urban and rural overhead distribution networks, serving as sectioning, tie and boundary switches. Adopting mature vacuum arc-extinguishing technology, they can reliably switch load and short-circuit currents and support local and remote operation. Equipped with intelligent controllers, they realize distribution automation functions including fault identification, isolation and remote monitoring.
