Abstract

The invention discloses an LSZH flame-retardant high-elasticity cable. The cable comprises a jacket with an annular cross section, a woven layer and a taped covering which are arranged from outside to inside, wherein two power lines are arranged inside the taped covering, each power line is formed by an outer insulating layer and an inner conductor, a plurality of propene polymer (PP) ropes are arranged between the taped covering and the insulating layers of the power lines, the insulating layers of the power lines are produced by flame retardant LSZH elastic materials, the PP ropes are made of flame-retardant zero-halogen PP materials, and the jacket is produced by LSZH flame-retardant thermoplastic polyurethane elastomer (TPE) materials. Therefore, the cable has the advantages of being high in flame retardance, good in low smoke effect and elastic property, low temperature resistance, suitable for outside and good in high temperature resistance.

Description

technical field [0001] The invention relates to a cable, in particular to a low-smoke, halogen-free, flame-retardant and highly elastic cable. Background technique [0002] Due to the improvement of modern people's living standards, some large shopping malls, supermarkets, and high-end hotels have followed. Unfavorable consequences, this leads to a long time, the aging of the wire rod leads to a fire, and billowing thick smoke is generated, people cannot escape from the scene, and eventually lead to death. Many fires show that people were not killed by fire, but by smoke. Contents of the invention [0003] In order to solve the above problems, the present invention provides a low-smoke, halogen-free, flame-retardant and highly elastic cable. The low-smoke, halogen-free, flame-retardant and highly elastic cable of the present invention has high flame retardancy, good low-smoke effect, good elasticity, and low temperature resistance. It is suitable for outdoor use and high...
