The Low Temperature Liquefaction Characteristic Test of

The results show that sf 6 gas is easier to liquefy in cold area, and the liquefaction temperature of Sulfr hexafluoride 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.

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 (insulating gas has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

Compressed to liquid form, larger amounts of SF 6 can be stored in smaller volume storage containers. For example, a typical 1.6 ft3 (44 liter) type-b cylinder is capable of storing approximately 115 lbs. (52 kg.) of SF 6 in liquid form. In gaseous form, the same cylinder will store only approximately 25 lbs. (11 kg.).
