  • Sulfur hexafluoride | F6S - PubChem

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

  • Cold Weather Operating Problems with SF6 Circuit Breakers

    Although the gas is nearly ideal, it does have one major disadvantage. The main disadvantage, from our perspective, is the relatively high liquefaction point of SF 6. Figure 3 The liquefaction occurs between -10&F and -30&F, depending on the density (70psig to 95psig ranges found in circuit breakers manufactured today 3) of the SF 6.
