  • SF6 properties, and use in MV and HV switchgear

    Cahier Technique Schneider Electric nO. 188 / p.7 Specific heat The volumetric specific heat of SF 6 is 3.7 times that of air. This has important consequences for reducing the effects of heating within electrical equipment. Thermal conductivity The thermal conductivity of SF 6 is below that of air but its overall heat transfer
