Abstract

The invention discloses an automobile cable. Special compounded rubber TPV insulation layers are arranged outside tinned copper-core flexible conductors to form insulated wire cores. After being twisted, the two insulated wire cores wrap polyurethane wrapping tape layers to form unit sets in a winding mode. After being twisted, the five unit sets wrap low-smoke halogen-free flame-retardant wrapping tape layers in a winding mode, shielding layers formed by braiding silvered copper wires are arranged outside the wrapping tape layers, and sheath layers made of 125 DEG C low-smoke halogen-free flame-retardant elastomer TPU materials are arranged outside the shielding layers. Five torsion-resistant nylon wire cores are arranged among the five unit sets. An auxiliary wire core is arranged in the center of the cable and is formed by wrapping three insulated wire cores in a polyurethane wrapping tape layer I and a metal shielding layer in a winding mode. The automobile cable is good in flame resistance, resistant to high temperature and low temperature, resistant to an acid, a base and oily water, resistant to tearing, flexible and friendly to environment.

Description

A kind of cable for car

Technical field

The invention belongs to electric wire field, relate to a kind of cable for car.

Background technology

Along with people's living standard is more and more higher, the enhancing just gradually of the consciousness of the earth environment protection that people live for self, the product of non-environmental protection is eliminated one after another, and novel environment-friendly product goes out not poor.Environmental protection more and more becomes one of significant problem concerning social development and people's life, equally also become gradually and guide and determine one of key factor of our wires and cables industry developing direction, the research of the environmental-protecting performance to cable is the grand strategy that cable enterprise realizes long term growth.Living standards of the people have improved now in addition, people have stepped into well-off society, car has also entered every household, car is motor vehicles, need electric energy normally to work, and electric energy is relevant with electric wire again, need to support the use with electric wire, in some exhibitions, see that some associated companies have released electric automobile, this also requires to provide corresponding environment-friendly type electric wire product simultaneously.

Summary of the invention

For overcoming above-mentioned deficiency, the object of the present invention is to provide a kind of cable for car with fire-retardant, high-low temperature resistant, acid and alkali-resistance, oil resistant water, tear-proof, softness and environmental-protecting performance.

The solution of the present invention is as follows: a kind of cable for car, extraordinary compounded rubber TPV insulating barrier is set in the outside of tin-coated copper core flexible conductor and forms insulated wire cores, wrapped polyurethane belting layer Component units group after two insulated wire cores pair twists, the stranded rear wrapped low-smoke non-halogen flame-retardant belting layer of five root unit groups, described belting layer arranges the screen of silver-gilt copper wire braiding outward, and described screen arranges outward and adopts 125 DEG C of restrictive coatings that low-smoke non-halogen flame-retardant elastomer material is made; Five antitorque nylon cores that draw are also set between five described root unit groups; Cable center also arranges a point of core, and described point core is made up of the outer wrapped polyurethane belting layer I of three insulated wire cores, metal screen layer.

Further, eight insulated wire cores are also set in described belting layer.

The conductor of cable adopts the special flexible conductor of tin-coated copper core, and its object is to increase the fire resistant anticorrosive performance of cable conductor, can have the conductor oxidation situation that effectively prevents that cable from occurring in the time that hot environment is used after the while is zinc-plated.

Insulating material adopts the extraordinary compounded rubber TPV of high-quality material, this material has following characteristics: (1) has good electrical property, there is good elasticity and compression resistant morphotropism, resistance to environment, resistance to ag(e)ing are equivalent to ethylene propylene diene rubber, its oil resistant solvent resistance is equally matched with polychloroprene rubber for general purpose simultaneously, and this has just ensured flexibility and the oil resistant water-based energy of cable; (2) 60-135 DEG C of the wide (– of temperature limit), in the situation that not bearing load, high temperature resistantly can reach 150 DEG C, this has just ensured the high and low temperature resistance of cable, soft durometer applied range (25A-70A), chromatophilous advantage has improved the degree of freedom of Products Design greatly; (3) good processing characteristics: available injection, the processing method processing of the thermoplastics such as extruding, efficient, simple, without increasing equipment, mobility is high, shrinkage is little; (4) environmental protection, recyclable, and six performances of Reusability are without obvious decline, and this has embodied the environmental-protecting performance of this cable; (5) light specific gravity (0.90-0.97), presentation quality is even, and surperficial class is high, good hand touch; (6) sense of touch of rubber, the processing method of plastics; (7) remarkable anti-dynamic fatigue property; (8) extremely excellent resistance to ozone and weather resisteant.

3, sheath material adopts 125 DEG C of low-smoke non-halogen flame-retardant elastomer materials of high-quality, this material has following characteristics: (1) has good electrical property, have good elasticity, resistance to ag(e)ing and oil resistance, this has just ensured flexibility and the oil resistant water-based energy of cable; (2) temperature limit wide (70-125 DEG C of –), this has just ensured the high and low temperature resistance of cable, soft durometer applied range (30A-80A) has ensured anti-wear performance and the warping strength performance of cable; (3) good processing characteristics: available general thermoplastic plastics shaping machine work, such as injection moulding, extrusion molding, blow molding, compression forming, pass mold forming etc.; (4) environmental protection, recyclable, reduce environmental pollution, expand resource regeneration source, this has ensured the environmental-protecting performance of cable; (5) light specific gravity (1.10-1.25); (6) show at normal temperatures caoutchouc elasticity, macromolecular material that again can plasticizing forming under high temperature, has mechanical property and the serviceability of rubber like, can process by thermoplastics again, and this has ensured the softness of cable; (8) extremely excellent ageing-resistant performance.
