The AC high voltage sulfur hexafluoride ring network switchgear in HXGN15-12 is a complete set of distribution equipment for 12kv three-phase AC 50Hz power supply system. It uses sulfur hexafluoride load switch as the main switch and the whole cabinet adopts air insulation, which is suitable for distribution automation. Compact and extensible complete set of distribution devices. It can be widely used in the construction of urban power grid, and can be applied to the distribution system of industrial and mining enterprises, high-rise buildings, residential areas, hospitals, schools, parks and so on, for the purpose of receiving and distributing electric energy. Mainly used for ring power supply and terminal power supply, but also suitable for loading pre-installed substation.
