advantages of Gas Insulated Switchgear detection systems

Gas insulated switchgear parts As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas.
