  • High voltage gas insulated switchgear: an overview | IET

    Abstract: In 1967 the first gas insulated metal-enclosed switchgear went into service in the German 110 kV network. Today GIS technology is successfully used for voltages up to 800 kV. GIS is an attractive alternative to conventional air insulated substations (AIS) because of the increased availability, reliability and the reduced

  • Gas insulated transmission lines for high power

    1998-1-11.. Experiences with gas insulated transmission lines (GIL)Back in the 1960s, with the introduction of sulphur-hexafluoride (SF 6) as an insulating and a switching gas, the basis was found for the development of metalclad high voltage substations.. On the basis of these developments and good experience of the SF 6 insulated metalclad high voltage switchgear, the idea to use highCited by: 28
