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

    Abstract 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.
