Development Sf6 Alternative Gases in Switchgears - Switchgear

Nov 23, 2019 · Development Sf6 Alternative Gases in Switchgears. Sf6 gas is widely used in electric power transmission and distribution systems, as for example in gas insulated switchgear (GIS), circuit breakers (CB) and load break switches. It combines unique electrical insulation and arc interruption capability. However, it is also a very strong greenhouse gas with a global warming potential (GWP) of about 23500 over a time horizon of 100 years and its use and release are regulated with further
