Introduction to Gas Insulated Substations / Switchgears (GIS) 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. Thereafter, they are taken to site for final assembly.
