SF6-alternatives Grid Solutions for middle voltages

2021-2-24At the end of life, disposal of the used sf6 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.

    2020-9-30solutions exist, especially for voltages rated up to 24kV. In many cases the alternative medium is a gas blend that includes either fluoronitriles or fluoroketones. Some of these solutions use a moderately increased gas pressure to achieve the required insulation strength, comparable to early designs using SF 6.
