  • Climate Change SF6 Gas | Energy Central

    Nov 19, 2020At the end of life, disposal of the used SF 6 gas is either recycled, or disposed by incineration. Alternatives for SF 6 are commercially available for use in electrical switchgear at low-to-medium voltages. Solutions for use at higher-voltages are more challenging, although pilot installations do exist at 145kV.
