Sulfr hexafluoride properties, and use in MV and HV switchgear

At high temperatures, the thermal conductivity curve of SF 6 (see fig. 4 ) reveals one of the exceptional qualities of the gas, which allows it to be used for extinguishing arcs by thermal transport. The peak of the thermal conductivity corresponds to the dissociation temperature of the SF 6 molecule at 2100 to 2500 K. The dissociation process absorbs a considerable amount of heat which is released when the molecules reform at the periphery of the arc, facilitating a rapid exchange of heatGet price
