insulating gas is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. Sulfr hexafluoride has two to three times the insulating ability of air at the same pressure. Sulfr hexafluoride is about 100 times better than air for interrupting arcs.

Where is insulating gas used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is insulating gas a health hazard? Pure sf 6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is insulating gas harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. What is the overall contribution of sf6 gas used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).
