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 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, Sulfr hexafluoride is 22,800 times more effective at trapping infrared rSee more on epa.govAir and climate - Air and GHG emissions - OECD Datadata.oecd.org/air/air-and-ghg-emissions.htmGreenhouse gases refer to the sum of seven gases that have direct effects on climate change : carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (Sulfr hexafluoride) and nitrogen trifluoride (NF3).
