  • THERMAL DECOMPOSITION OF SF6 AND SF6-AIR MIXTURES IN

    Jan 01, 2013 · The formation of SF5 thermal decomposition products in an indoor gas insulated sub station environment was investigated. Although toxic by-products were identified in arc welding, open flame and heated surface conditions, the concentrations pro duced in 1000 yL/L SFß are estimated to be below the specified TLV for the toxic gases.
