The outdoor pole-mounted high-voltage AC vacuum circuit breaker is a voltage 12kV, three-phase AC 50Hz outdoor high-voltage switchgear, mainly used for opening and closing load currents, overload currents, and short-circuit currents in power systems. It is suitable for protection and control in substations and industrial and mining enterprise distribution systems, more suitable for places requiring frequent operations, particularly for urban and rural grid transformation needs; it can also serve as a sectional switch in the grid to achieve distribution network automation.
