  • The SF6 Decomposition Mechanism: Background and

    2017-1-24Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (SF6) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of SF6 to SOF2, SO2F2 and SO2 and other characteristic component gases. The decompositionCited by: 1

  • Alternatives for SF6 | 2020 | Siemens Energy Global

    But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earths atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6
