Abstract

The invention discloses an automobile wire, comprising an intertwisted conductor and an insulation layer wrapping the intertwisted conductor; the intertwisted conductor is obtained through intertwisting 156-190 and or 612-786 identical conductive monofilaments; the diameter of the conductive monofilaments is 0.21mm-0.41mm; the total area of the intertwisted conductor is 20mm2-25mm2; the material of the insulation layer is a deposition method silicon rubber or a vapor phase method silicon rubber, the temperature resistance level of which is 200 DEF temperature resistance; the thickness of the insulation layer is 0.5mm-1.0 mm; the insulation layer thickness is 0.5mm-1.0mm; and the density of the insulation layer is 1.2g.cm-3-2.0g.cm. The automobile wire is high in temperature resistance and the aging resistance; the wire coil is not cracked after the aging test for 3000 hours under 200 DEG; the wire is applicable to the automobile; the wire scratching and wearing resistance are stable, and the scratching and wearing resistance number is 1500 times to 1700 times.

Description

technical field [0001] The invention relates to an automobile electric wire, in particular to an automobile electric wire. Background technique [0002] Cars are ubiquitous in our lives. With the improvement of people's safety awareness, the performance requirements for automotive wires are also gradually increasing. Different from ordinary cables, automotive cables have many properties and requirements different from ordinary cables, such as high temperature aging resistance, wire structure, and wear resistance. [0003] Due to the relatively narrow use environment of automobiles, a thin-walled structure is required for the insulating layer of electric wires. However, most of the existing thin-walled electric wires have poor mechanical strength performance, especially poor scratch resistance. Generally, their scratch resistance can only reach 1350-1400 times, or even less, and their scratch resistance is very poor. unstable. Contents of the invention [0004] The techn...
