sf 6 leakage and quality for HV MV

Fluoroketone, carbon dioxide and oxygen for high-voltage (HV) GIS. Fluoroketone, nitrogen and oxygen for medium-voltage (MV) GIS. This fluorinated molecule rapidly decomposes under ultraviolet light in the lower atmosphere. Therefore, the molecule's atmospheric lifetime is short (around 15 days, versus 3200 years for sf 6).

  • SF6-alternative gases HV MV Equipment for railroad

    SF6-alternative gases HV MV Equipment for railroad. Gas leakage IEC specifies an annual maximum sf 6 leakage rate of 0.5 % or 1 %. Experience from several high and low temperature tests and decades of operational experience show that the leakage rate of Siemens circuit breakers is below 0.1 % per year.
