Overview:
FZN25-12 series vacuum load switches and combined electrical appliances are suitable for 10-12kV, 50Hz three-phase AC power distribution systems. They have the advantages of no pollution, no fire hazard, no explosion hazard, and can be operated frequently. It can be used as the main component of ring main unit, box-type substation or other types of switch cabinets for the control and protection of inverters, cables, overhead lines and other power equipment. It is widely used in power distribution systems in factories, communities, high-rise buildings, schools, parks and other places.
