Insulating gas Gas Insulated Switchgear cart

Gas insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings. Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons.

  • 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
