  • SF6 GAS - DILO

    DILO’s path in SF6 gas handling started in 1967, when we supplied a complete piping system for installation of the first SF6 gas insulated switchgear. Since then, our product portfolio has successively been developed to the widest product range of emission-free gas handling equipment worldwide.

  • News Room : GE Grid Solutions

    It was just two years ago that GE announced a breakthrough in developing a substitute for SF6 in gas-insulated equipment. Such a substitute had become necessary because SF6, despite its undeniable qualities—its arc-quenching and dielectric capabilities—has a global warming potential (GWP) 23,500 times that of CO2, with a lifetime in the atmosphere of over 3,000 years.

  • Gases and Gas Mixtures for Insulation Purposes | SF6 Gas

    SF 6 /N 2 mixture is the one that has been found to be a good replacement for SF 6. SF 6 /N 2 mixtures have been used in Gas Insulated Transmission System and were found to perform well. Also, the work done so far has shown that the ability of SF 6 /N 2 mixtures to quench high current arcs is promising. The cost of such mixtures is low and are less sensitive to field non-uniformities present inside the

    Abstract: Investigations of the dielectric properties of SF/sub 6/, N/sub 2/ and mixtures have been carried out using a full scale model of a gas-insulated busbar (GIB). The breakdown characteristics under clean conditions are similar to those in a uniform field gas gap. The breakdown voltage is the maximum in SF/sub 6/ and the minimum in N/sub 2/, and shows positive synergism in gas mixtures.
