  • Reducing Sulfur Hexafluoride (SF6) Emissions from Gas

    Jan 01, 2015 · SF6 also lasts in the atmosphere for more than 3,000 years after it is released. As an excellent insulator, SF6 is often found in gas-insulated switchgear (GIS), equipment used in high-voltage electrical systems to control the flow of electrical current. SF6 routinely leaks into the atmosphere from closures and joints in GIS equipment.
