sf 6 storage for Substation

Powerplant and substation electrical staff are very familiar with sulfur hexafluoride or SF6 which is a common insulating gas used in electrical equipment like electrical switches and circuit breakers. For many decades, SF6 has been the go-to dielectric insulating material for high-voltage electrical systems installed in enclosed spaces.

  • SF6 Gas Use in Electrical Applications - SF6

    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

    implications of SF 6 are coming under scrutiny. ABB has now developed an alternative that in certain cases comes close to the performance of SF 6. Shown is high-voltage GIS. However, SF 6 is a greenhouse gas and the life-cycle management costs incurred when handling SF 6, particularly when decommissioning aging substations, are increasing.
