Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (insulating gas) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on sf 6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, insulating gas is 22,800 times more effective at trapping infrared radiatioSee more on epa.govsf 6 Generator Circuit Breaker Suppliers
