  • Gases and Gas Mixtures for Insulation Purposes | SF6 Gas

    In summary, it may be said that there is an urgent need to significantly reduce the use of SF 6 gas and its leakage from power apparatus. Use of gas mixtures appears to be feasible, but it has to be ensured that there is no loss in the performance of the equipment. Therefore, further research has to be carried out to identify a suitable gas mixture, its pressure and its arc interruption capability to be used in the
