  • A review on SF6 substitute gases and research status of

    Nov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.
