2020-3-12Sulfur Hexafluoride (SF6) Gas The insulating and arc quenching medium -SF6 SF6 gas, previously used mainly in circuit breaker of higher voltage level and with successful achievements, has now been found into medium voltage load switching system in recent years. This change happens to systems all over

2014-11-11are also likely to purchase 275kV / 400kV outdoor SF6 switchgear to specification 62271-1 which may have a design leakage rate of up to 1%. These IEC specifications define best practice. We are not aware of any 132kV, 275kV and 400kV SF6 switchgear that offers exceptionally low leakage rates. More explanation on this design leakage
