SF6-alternatives Insulated Equipment for high voltages

2017-3-16Abstract. Since the 1970s, transmission and distribution network relies on SF 6 technology because of its remarkable arc quenching properties and dielectric insulation. However, with its high GWP of 23,500 and an atmospheric lifetime of 3200 years, the SF 6 insulating gas has significant environmental impacts if it leaks intoCited by: 5

2020-8-12In the high voltage power industry sulphur hexafluoride (SF6) is currently used to insulate high voltage equipment worldwide such as gas insulated transmission lines (GIL) and gas insulated switchgear (GIS). SF6 is a man-made gas and has a global warming potential 23,500 times [1] that of

2016-12-12For decades, the unique properties of sulfur hexafluoride (SF6) have made it popular as an insulation and switching medium for electrical switchgear. However, SF6 is a greenhouse gas and there are life-cycle management costs associated with its use. For some years, ABB has been conducting research into alternatives
