sf6 gas insulated switchgear evacuation for KEPCO

sf6 gas insulated switchgear evacuation for KEPCO

Gas Insulated Lines have now been in operation in AC for many years, up to 420kV. They are under development tests in DC at 500kV. They will make it possible to transmit a large flow of power through a single cable system.

  • Introduction to Gas Insulated Substations / Switchgears

    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. Thereafter, they are taken to site for final assembly.
