Product Overview
ZW32SR-12 primary and secondary deep fusion complete sets of column circuit breaker adopts the principle of vacuum arc extinguishing, permanent magnet operating mechanism (elastic operation mechanism), and integrates microprocessing technology, modern network communication technology and switch manufacturing materials. Outdoor power distribution equipment with rated voltage of 12kV and 50Hz three-phase AC. The product is widely used as a disconnect or contact switch in the urban power grid, or in the rural power distribution system. The outgoing switch of outdoor substation can effectively complete the work of the traditional recloser, dividing and closing the load current and short-circuit current.
