  • Panel discussion: The pros and cons of using SF6 gas in

    Sulphur hexaflouride (SF6) gas has been used in MV and HV switchgear for many years. It is said to be highly toxic and a potent greenhouse gas. It is used because of its excellent electrical insulation properties, but recently some switchgear companies have suggested other solutions. In our virtual panel discussion we asked some

    SF6 gas was at first used in switchgear because of its highly superior dielectric properties with respect to air. Its impor tant arc interruption properties were dis covered later and can be summarized as: • its higher capacity for evacuating the heat created during arcing, • its decomposition is a perfectly rever
