KSF6051 Series SF6 Gas Recovery Purifier

Ksf6051 series SF6 gas recovery and purification unit




As an insulating gas, SF6 gas has non-toxic, non combustible and good insulating properties. Its insulating strength is much higher than that of traditional insulating gas, and it has good arc extinguishing property. Therefore, SF6 gas is widely used in SF6 Electrical appliances. Because SF6 gas is expensive, and under the action of arc, electric spark and corona discharge, it will decompose and produce toxic components. Therefore, SF6 gas needs to be recovered when SF6 Electrical equipment is used. The device is a special equipment for recovering and filling SF6 gas when manufacturing and maintaining SF6 Electrical equipment.
