GAE1250 / GAE1250kMAX Fully gas insulated modular system MV Switchgear for Substation Solutions Design characteristics Key components Vacuum circuit breaker (VCB) All LSV type modular cubicles under GAE1250 and GAE1250kMAX systems incorporate a compact three pole circuit breaker with vacuum breaking technology thanks to the axial magnetic field type vacuum interrupter (VI). Two massive copper contacts, one fixed and the other moving, inside the VI's ceramic body form the main connection parts of the VCB circuit. During the switching off, an arc occurs in the vacuum contact chamber from the...

GAE1250 / GAE1250kMAX Fully gas insulated modular system MV Switchgear for Substation Solutions Main compartments The GAE1250 and GAE1250kMAX systems present a structure divided into independent compartments: Driving mechanism 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 < 2pC). Each MV compartment is...
