3 Phase AC High Voltage 12KV Outdoor Vacuum Load Break Switch

FZW -40.5 outdoor vacuum disconnecting load switch (short for load switch) is outdoor HV switchgear with three-phase AC 50Hz, rated voltage12/40.5kV. It is used for switching on/off load current in city or country distribution systems or breaking transfer currentof fuses. Matching with motor mechanism and contoller, it can be used as a section switch or sectionalize. It uses new insulation structure design and vacuum explosion chamber. After switching off, the load switch has an obvious visible fracture. It also has functions of disconnecting switch. Addinally, with big switching capacity and no oil, long electricity life and non maintenance, it will not pollute environment and explode.
