  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    sensors for gas-insulated switchgears (GIS) The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables. Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900).
