Medium-Voltage Switchgear up to 24 kV, SF6-insulated, Modular Design, Type GAE, Series GAE1250 General Information/Description The HV compartment This is a gas-tight welded tank made from stainless steel, which houses all the live parts including the busbars. The incoming and outgoing power feeders, as well as the connection of the fuses is made through cast-resin bushings that are individually tested for maintenance of the maximally admissible partial discharge values (TE ï 2 pC). Each HV compartment is equipped with a stainless steel bursting membrane that is specifically designed for the...

Medium-Voltage Switchgear up to 24 kV, SF6-insulated, Modular Design, Type GAE, Series GAE1250 SF6 the insulating and arc quenching medium SF6 the insulating and arc quenching medium Sulphur hexafluoride (SF6) gas has in recent years increasingly found its way also into medium-voltage load switching systems, having been previously successfully used mainly in circuitbreakers up to highest voltage levels. The high operational safety of the system (external influences such as humidity, conductive dust, etc. have no effect) virtually excludes arc-faults. Should such a fault nevertheless occur,...
