Background technology
Electric wire is a kind of in order to transmit electricity (magnetic) energy, information and the wire product of realizing electromagnetic energy conversion.Electric wire, as the main carriers of electric power transfer, is widely used in the aspects such as appliance equipment, illuminating line, household electrical appliance, and the quality of its quality directly has influence on project quality and consumer's the security of the lives and property.Although wires and cables industry is a supporting industry just, in occupation of the output value of Chinese electrician trade 1/4.Its product category is numerous, and range of application is very extensive, relates to the industries such as electric power, building, communication, manufacture, all closely related with each department of national economy.Electric wire is also called as national economy " artery " and " nerve ", the various motors of transmission of electric energy, transmission of information and manufacture, instrument, instrument, realizing the indispensable basic equipment of electromagnetic energy conversion, is necessary basic product in following electrification, informationized society.
Current wires and cables industry is in the face of the continuous derivative product making new advances of special occasions demand, as fire-resistant cable, flame-retardant cable, low smoke and zero halogen/low-smoke low-halogen cable, termite-proof, anti-mouse cable, oil resistant/cold-resistant/heatproof/wear-resisting cable, medical/agricultural/mining cable, thin-walled electric wire etc.
Along with the raising of people's awareness of safety, people are more and more higher to performance requirements such as the anti-flammability of electric wire, fire resistances, and high flame-retardant electric wire and cable is the emphasis that current people relatively pay close attention to.
In many large-scale public arena breaking out of fire accidents, because sucking, electric wire (high polymer) discharges the reason of most of personnel's death when burning, corrosive and poisonous dense smoke gas suffocates.Wire cable material is carried out to fire-retardant and low cigarette processing, and oneself fundamentally prevents from and reduces fire occurring through being acknowledged as, and reduces the Important Action of people's life and property loss.
