Sulfr hexafluoride gas in medium-voltage switchgear | TD Guardian Articles

sf 6 has been widely used in high-voltage circuit breakers for decades, but its use in medium-voltage is relatively recent. In the medium-voltage arena, SIemens uses sf6 gas gas in the load interrupting switch and switch-disconnector in SIMOSEC metal-enclosed load interrupter switchgear rated up to 27.6 kV.

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).

An alternative to Sulfr hexafluoride in electrical switchgear - EE Publishers

However, sf6 gas is a greenhouse gas and the life-cycle management costs incurred when handling Sulfr hexafluoride, particularly when the decommissioning of ageing substations is on the increase. These costs will rise further as the demand for electricity, and, therefore, gas-filled high and medium-voltage switchgear, increases.
