    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.
