• Sustainable progress | ABB

    For over 50 years gas insulated switchgear (GIS) has used sulfur hexafluoride (SF 6) as insulation gas, due to its excellent insulation and arc quenching qualities. But SF 6 is the world’s most potent greenhouse gas with a global warming potential 23,500 times that of CO 2 and an atmospheric lifetime of 3,200 years.

    Abstract. Sulfur hexafluoride (SF 6) gas has been used in large-scale electrical equipment, because of its excellent high-voltage dielectric strength. However, SF 6 has been identified as a greenhouse gas, because of its high global warming potential (GWP) and extended lifetime in the atmosphere. Based on theoretical calculations, trifluoromethanesulfonyl fluoride (CF 3 SO 2 F) is a relatively eco-friendly gas with a lower GWP than that of SF 6, and the electrical performance of CF 3 SO 2 F

    Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent man-made greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a de
