Interaction Mechanism between the C4F7N–CO2 Gas Mixture and

Sulfur hexafluoride (SF 6) has been widely used as gas insulating medium in all kinds of gas-insulated equipment (GIE) since the 1970s because of its excellent insulation and arc-quenching properties. (1−4) However, SF 6 is one of the greenhouse gases with a global warming potential (GWP) 23 500 times higher than that of CO 2 (over a time horizon of 100 years) and an atmospheric lifespan of 3200 years. (5−7) The power industry accounts for 80% of the worldwide sale of SF 6.Get price
