NDIR SF6 room leak rate for cables

NDIR SF6 room leak rate for cables

The density of sulfur hexafluoride is relatively high at room temperature and pressure due to the gas's large molar mass. Unlike helium, which has a molar mass of about 4 g/mol and pitches the voice up, SF 6 has a molar mass of about 146 g/mol, and the speed of sound through the gas is about 134 m/s at room temperature, pitching the voice down ...

  • SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS

    The loss rate of sulphur hexafluoride is generally about 0.5 percent by volume of SF 6 per year. These leaks must be eliminated immediately, since sulphur hexafluoride is extremely harmful to the environment. Depending on the operating duration SF 6 must therefore be checked and replaced regularly.
