HXGN-12 ring net vacuum circuit breaker medium voltage switchgear  

           the 12kv medium voltage switchgear  is suitable for the distribution system of mining and industrial enterprises, residential quarters, high-rise buildings, school and park as the power supply unit and terminal distribution equipments of the indoor 10KV, 50Hz AC three-phase.  12kv  medium voltage switchgear  can connect and break the rated load current and the no-load current of the transformer, and  12kv  medium voltage switchgear can also connect or break the capacitor current of the overhead lines, cable lines or the capacitor bank.         

          Load switch-fuse combination cabinets can break the rated short-circuit current at one time. And 12kv  medium voltage switchgear  used to protect, receive and control the power in the distribution equipments.  12kv switchgear is mainly equipped with FN5, FN7 switches, FN12 variable pressure differential switch, FZN121, FZN25 vacuum switch.
