  • SF6 compressor - gas recovery: HAUG Sauer Kompressoren AG

    The greenhouse effect for SF6 is 23'900 times as large as for the same quantity of CO2. In the 1997 Kyoto protocol, SF6 was listed as one of the six greenhouse gases which are prohibited from freely escaping into the atmosphere. Despite its harmfulness, SF6 is an essential gas and is used, for example, as an insulating gas in high voltage switches.

  • N2/SF6 gas Mixtures — Large Scale Application in Gas

    The application of N 2 /SF 6 gas mixtures with SF 6 -contents between 10 % and 20 % reduces the costs for the insulating gas remarkably. This is of great importance when GIL is to be used for long distance bulk power transmission. By this, also the acceptance for long distance applications of this technique is improved on the user side.
