  • Economics Between Conventional and Gas Insulated

    Switchgear and its components are a vital link in the transmission and distribution chain. Gas insulated switchgear (GIS) using Sulphur hexafluoride (SF6) has been in use since the 1960s, at high voltage (HV) application first and medium voltage (MV) much later. Air is also used for insulation but SF6 has significant property advantages,
