  • GIS Advantage - Power Line Magazine

    May 07, 2016GIS is an effective, although costly, form of switchgear, in which all the equipment is contained in a sealed metal enclosure with sulphur hexafluoride gas (SF6) as the insulating medium. Other common types of switchgear are air-insulated switchgear (AIS), oil-insulated switchgear (OIS) and vacuum-insulated switchgear.

  • Introduction to Gas Insulated Substations / Switchgears (GIS)

    The SF6 gas provides the phase to ground insulation. Gas insulated switchgear parts. As the dielectric strength of SF6 gas is higher than air, the clearances required are smaller. Hence the overall size of each equipment and the complete sub-station is reduced. The various modules are factory assembled and are filled with SF6 gas.

  • Alternative insulation gas for medium-voltage switchgear

    Jun 16, 2016Abstract: Although the contribution of SF6 (sulfur hexafluoride) emissions from gas insulated medium-voltage switchgear to man-made global warming is very small, an eco-efficient insulation gas will contribute to a reduction in the carbon footprint of the electricity grid. Based on fluoroketone molecules an alternative to SF6 gas insulation has been developed for medium-voltage switchgear
