SF6 handling in industry | Sauer Compressors greenhouse potential of SF6 is estimated to be 23,000 times higher than that of carbon dioxide. SF6 can remain stable in the atmosphere for up to 3,200 years. As a result, it can only be used in closed circuits in industry. For maintenance purposes, SF6 must be evacuated from gas insulated switchgear.
SF6: Does its Impact Outweigh its Benefits? | T&D World gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.
