Problems solved by technology

[0003] The structure of the traditional power transmission line, that is, the cable, is a copper conductor covered with PVC insulating material. Although it can meet the transmission requirements, it has the following defects: First, it has poor temperature resistance. The temperature can only reach 160°C; second, it is inconvenient to lay, and the conductors are usually twisted in the same direction, so that the bending performance of the finished cable is poor, and a large laying bending radius is required; third, single-layer insulation is used, which is safe and reliable Fourth, because there is no shielding layer, the electromagnetic waves generated when the power line transmits alternating current can easily interfere with the intelligent circuit system in the car, and even cause the car's intelligent system to malfunction or fail to work normally, causing safety accidents

Embodiment Construction

[0019] The following will further describe the present invention in conjunction with the accompanying drawings of the embodiments, which will help the understanding of the technical contents and effects of the present invention, but the embodiments do not constitute a limitation to the technical solutions of the present invention.

[0020] Referring to FIGS. 1 to 3 , there are 19 conductive units 11 . The 19 conductive units 11 are 12 times the pitch ratio and twisted in S direction to obtain the cable core 1 . As shown in Figure 2, it exhibits complex twisting in the S direction. The pitch ratio referred to here is the stranded wire pitch and pitch diameter ratio well known in the wire and cable industry, that is, the axial length of the single wire in the stranded wire turning around the stranded wire is called the stranded wire pitch; the pitch diameter ratio is The ratio of strand pitch length to strand diameter. For each conductive unit 11, the applicant exemplifies that...

Abstract

A cable for hybrid vehicle includes the cable core and the outer insulation layer, as well as shielding layer, isolation layer and protection layer out of the insulation layer in order. The cable core is composed by electric conducting units kinked together, each of the units is composed by kinked wires. The cable is capable of bearing 125oC for long term and 250oC for short term.

Description

technical field [0001] The invention belongs to the technical field of wires and cables, in particular to a cable for hybrid electric vehicles. Background technique [0002] With the development and popularization of the automobile industry, people pay more and more attention to the related energy, environmental protection and safety issues. Therefore, the development of high-efficiency, energy-saving, safe and environmentally friendly, comfortable and convenient hybrid vehicles has become the development direction of the automotive industry. Due to the advantages of low exhaust gas emission, low fuel consumption, low noise, and safety, hybrid electric vehicles have broad market prospects in today's increasingly scarce energy sources. Since the power system of a hybrid electric vehicle is mainly composed of a traditional internal combustion engine, a battery and a motor, and the kinetic energy and electric energy need to be converted frequently, it is required that a hybrid...
