External high-voltage cable distribution box. The control switch adopts sulfur hexafluoride load switch or vacuum circuit breaker. Touchable shielded silicone rubber cable joint has strong short-circuit current closing ability and breaking ability of active load and no-load cable current.

ZW32-12 outdoor high-voltage vacuum circuit breaker is a three-phase AC 50 Hz, outdoor high-voltage switching device with a rated voltage of 12 kV. It is mainly used to open and close the load current, overload current and short-circuit current in the power system in the distribution power grid.

ZW20-12 vacuum circuit breaker uses vacuum arc extinguishing and SF6 gas as the insulating medium, and is filled with slightly positive pressure SF6 gas inside. It has zero leakage and is not affected by the outside world. It belongs to a new generation of external household vacuum circuit breaker with maintenance-free, excellent performance and high reliability.
