( Industry news] 【 Poly petrochemical learn encyclopedia 】 Fire accident analysis and countermeasure of wire and cable industry qybee P most modern high-rise building fire accident is due to the joint of the cable loose the name of the contact oxidation, and poor contact, causing resistance increases, have caused overheating or lighter. Especially in the modern intelligent building, its have tens of thousands of cables and cable junction, electrical and electronic equipment in the long time running, can make the wire, cable temperature increasing, lead to contact wires and insulation accelerated aging or damage, fire accident prone to overheating. Human factors caused another wire, cable fire accident causes. Hazard analysis in the high-rise building, because the wire and cable laying into beam erection online rack, once produce a fire in the wire, cable, its effect is envisaged. For wire, cable insulation layer is used by some flammable rubber, PVC macromolecule organic compound materials such as hydrogen, this kind of material produced during burning heat up to ~ kJ/kg. Wire, cable copper melting point about ℃, aluminum conductor in ℃, melting point and the melting point of wire, cable insulation layer is far lower than the values, such as PVC plastic melting point is only ℃. Electrical fire accident chain can also cause other accidents. Malformation, plastic wire, cable not only spread fast burning, but also produce a lot of poisonous and harmful gases, such as hydrogen chloride, carbon monoxide, make the person is in a state of asphyxia, poisoning, facing death risk of death. Incident prevention countermeasures of prevention countermeasure technology for high-rise building construction of wire and cable for disposal techniques. Building, between layer and layer, layer and wall, frame and layer, the elevator shaft and between frame and control room should be strict with fireproof plugging material, good sealing up, when the frequency that wire, cable fire will not string to the other direction. The selection of the design countermeasures of wire and cable design to develop. Because the ancient high-rise building wire and cable to the vertical and horizontal, confused now generally take the flame retardant wire. Flame retardant wire and cable is self-extinguishing with the performance of the secondary. Its production process is independently in does not affect the wire performance, under the premise of physical properties, mechanical properties, add high oxygen flame retardants in the insulation layer, can effectively form a protective layer.
