SF6 decomposition leakage and quality for 220kv

SF6 decomposition leakage and quality for 220kv

SF6 can be heated without decomposition to 500&C in the absence of catalytic metals. SF6 is non-flammable and hydrogen, chlorine, and oxygen have no action on it. SF6 is insoluble in water and is not attacked by acids. Toxicity of arc products. Toxic decomposition products are formed when SF6 gas is subjected to an
