HXGN-12 SF6 Gas Insulated Electrical Medium Voltage Ring Mian Unit

HXGN  - 12 box type fixed AC metal-enclosed ring network switchgear (hereinafter referred to as "ring network cabinet/switchgear") is suitable for power distribution systems in areas such as industrial and mining enterprises, residential areas, high-rise buildings, schools, and parks. It is used as an indoor AC three-phase 12kV, 50Hz ring network power supply unit and terminal power distribution equipment. It can disconnect or close the rated load current and transformer no-load current and can disconnect or close the overhead line, cable line, or capacitive current at a certain distance. The load switch fuse combination cabinet can disconnect the rated short-circuit current at one time. In the power system, as the protection of distribution equipment and the distribution and control of electric energy, it has a perfect "five prevention" locking function.
