A scratch-resistant and bending-resistant motor connecting cable for a new energy automobile comprises a wire core, an inner protective layer, a braided layer, an aluminum foil layer and a sheath layer. The wire core comprises a central conductor and an insulating layer. The insulating layer is made of first low-halogen cross-linked polyolefin and comprises the following raw materials in parts byweight: 40-45 parts of polyethylene; 5-7 parts of POE; 6-9 parts of ethylene propylene rubber; 15-18 parts of EVA; 22-26 parts of decabromodiphenyl ethane; 9-12 parts of antimony trioxide; and 2-3 parts of an antioxidant. The sheath layer is made of second low-halogen cross-linked polyolefin, and comprises the following raw materials: 32-36 parts of polyethylene; 5-7 parts of POE; 6-9 parts of ethylene propylene rubber; 15-18 parts of EVA; 24-30 parts of decabromodiphenyl ethane; 9-12 parts of antimony trioxide; and 2-3 parts of an antioxidant. The insulating layer can greatly improve the adhesive force of the insulating layer, strengthens the stress protection of the central conductor, facilitates the cutting and processing of a wire, and improves the reliability of electrical performances. The sheath layer solves the problem that the appearance of a traditional material becomes white after stress is applied to the surface of the wire, the scratch resistance of the cable can be improved, and wire extrusion and wire harness processing and wiring are facilitated.

    一种新能源汽车用耐刮擦耐弯折电机连接电缆,包括线芯、内护层、编织层、铝箔层及护套层;线芯包括中心导体及绝缘层;绝缘层由第一低卤型交联聚烯烃制成,原料包括:聚乙烯40~45份;POE 5~7份;乙丙橡胶6~9份;EVA 15~18份;十溴二苯乙烷22~26份;三氧化二锑9~12份;抗氧剂2~3份;护套层由第二低卤型交联聚烯烃制成,原料包括:聚乙烯32~36份;POE 5~7份;乙丙橡胶6~9份;EVA 15~18份;十溴二苯乙烷24~30份;三氧化二锑9~12份;抗氧剂2~3份。本发明绝缘层能够大幅度提升绝缘层的附着力,加强了对中心导体的受力保护,易于导线裁剪加工并加强了电气性能可靠性。护套层解决了传统材料在线材表面受到应力后表观变白问题,可提升电缆耐刮性能,便于导线挤出过程和线束加工布线。
