The SF 6 gas which has high dielectric property acts as an insulating medium to the High Voltage or Extra High Voltage substation equipment. Generally, Gas Insulated Substations

Sep 03, 2018Sulphur hexafluoride (SF 6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF 6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and

The SF6 Gas Insulated Substation (GIS) is an urban, low-profile substation that feeds the downtown Orlando load. The GIS operates at 115 kV in a 5-position ring bus configuration. It is made up of three transmission lines and two transformer bays. The first two 115-kV lines are high pressure fluid-filled (HPFF), and the third is XLPE.
