General
HXGN□-10Z ring net vacuum 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. It can connect and break the rated load current and the no-load current of the transformer, and it 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 it used to protect, receive and control the power in the distribution equipments. It is mainly equipped with FN5, FN7 switches, FN12 variable pressure differential switch, FZN121, FZN25 vacuum switch.
