The power cable of burning flammable gas due to external heating to achieve the purpose of the flame retardant, must contain three elements cause a fire, namely: the combustible gas, heat and oxygen. Therefore, the flame-retardant power cord cables are generally used in the insulation, sheathing and fill material, add a halogen-containing halide and metal oxides, from the perspective of flame-retardant to evaluate, which is excellent, but , because these materials contain halide, when burned, release a lot of smoke and halogenated hydrogen, so the poor visibility when the fire evacuation and fire, a great hindrance to the safety of personnel, and others for toxic gas suffocation.
