Myth About SF6 Gas In Electrical Equipment

2019-4-22 · 21. How much SF6 (quantified in kg) can escape due to “normal” leakage? This depends on the filling quantity, which depends on the rating and design of the equipment (volume and pressure). For HV switchgear the emission factor ranges from about 0.1% per year to 0,5% (0,5% per year is the maximum acceptable leakage rate according to IEC

SF6 Gas - [PDF Document]

For loose components however, SF6 technology is sharing the market with air for LBS Load Break Switches: but air market share is rapidly decreasing to the benefit of SF6, and with vacuum for CBs. Vacuum and SF6 CBs are modern solutions, and will continue to expand due to the decreasing influence of minimum oil technology.
