• 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.
