SF6 gasplant QUALITY for high voltages

SF6 gasplant QUALITY for high voltages

The main area of application for the non-flammable gas sulphur hexafluoride (sf6-gas) 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).
