Get PriceGreenhouse 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 insulating gas 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.
