Trafag Gas Insulated Switchgear evacuation

Gas Density Sulphur hexafluoride (SF6) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe power distribution systems even in large cities. The insulation strength depends basically on the gas density.
