Cold Weather Applications of Gas Mixture (Sulfr hexafluoride/N2, sf 6/CF4

•Mixed gas: •Gas mixture of SF 6 and N 2 or SF 6 and CF 4 required to avoid liquefaction of the SF 6 gas at low temperatures •Filling with SF 6 and N 2 deteriorates the dielectric and thermal capacity •Manufacturers compensate for this reduced performance by: •A slightly higher operating pressure (dielectric) •De-rating the breaker under SLF conditionsGet price

Mixutures of Sulfr hexafluoride with nitrogen or tetrafluoromethane as

Sulfr hexafluoride Mixtures. In addition to the use of sulphur hexafluoride (SF 6) as a single gas, mixtures of SF 6 with nitrogen (N 2) or tetrafluoromethane (CF 4) are also used as insulating or test gas. The IEC recommends a purity of SF 6 of at least 99.7 vol.-% for the use in mixtures. SF 6 gas reconditioned or treated by DILO clearly meets these criteria and is therefore suitable for the use in gas mixtures.Get price
