    • FZW28-12 Outdoor AC high voltage boundar y vacuum load switch

    FZW28-12 Outdoor AC high voltage boundar y vacuum load switch

    FZW28-12 series outdoor AC high voltage boundary vacuum load switch is suitable for outdoor three-phase AC power distribution system with rated voltage of 12kV and rated frequency of 50Hz. It is used for opening and closing load current and closing short circuit current. Applicable to substations, industrial and mining enterprises and cities, agricultural networks for protection cities, agricultural network automation distribution network and frequent operations. The boundary load switch consists of two parts, the FZW28-12 vacuum load switch and the controller, which are electrically connected through an air socket and an outdoor sealed control cable. It can reliably judge the zero-sequence current and phase-to-phase short-circuit current of the milliampere inside and outside the detection circle, which can be suitable for the distribution system with different neutral grounding methods.
