  • Properties of SF6 Gas ~ your electrical home

    The temperature at which the SF6 gas changes to liquid state depends on the pressure. With higher pressure, the temperature increases. To avoid the liquefaction of SF6 gas. the temperature of SF6 should be maintained above certain value. For atmospheric pressure, SF6 gas starts liquefying at a temperature of about 10 & C.
