The Low Temperature Liquefaction Characteristic Test of

The results show that Sulfr hexafluoride gas is easier to liquefy in cold area, and the liquefaction temperature of insulating gas 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 gaz sf6 gas from liquefaction.
