Substation and switchgear techs: GIS is seen everywhere ...· SF6 is thermally stable, has excellent thermal transfer characteristic, is non-flammable, has unmatched dielectric strength, and is self-healing. Those were just some of the few SF6 characteristics and why it is widely used nowadays. However, SF6 is a greenhouse gas necessitating SF6 filled equipment being closely monitored for leaks.[email protected]
