    The results show that SF 6 gas is easier to liquefy in cold area, and the liquefaction temperature of SF 6 gas is in proportion to gas pressure. So the liquefaction temperature of electric equipments operated in cold area should not be higher than the lowest area temperature. Otherwise, measures must be taken to prevent SF 6 gas from liquefaction.

    As a hybrid of the high-pressure and refrigeration process, heat-exchanged systems rely on a series of forced-air coolers to extract heat from the compressed SF 6. As a benefit of reduced temperatures and pressures, this approach allows gas to be liquefied at a slightly faster rate than the direct high-pressure approach.
