SF6-alternatives vacuum Quantitative

Dec 12, 2016For 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 with lower environmental impact but with […]

  • Alternatives to SF6 for Magnesium Melt Protection

    SF6. Using alternative fluorine-based blended melt protection in place of an SF6- based cover gas process can reduce metal loss (% dross) due to oxidation and pro- vide associated cost savings, as shown in the hypothetical example in the graph on page 5. This example also shows that as the incoming Mg raw material price

  • The Impact of Carrier Gas Selection on SO2 and SF6 Melt

    IMA Program for SF6 Alternatives 1999 - IMA initiated a development program seeking alternatives to SF 6 due to environmental impact. 2000 – 2003 The program at SINTEF, a Norwegian Research Institute, evaluated other fluorine containing compounds. SO2 was not considered due to historical issues associated with poor usage practices.
