[0002] The car wire is a kind of connecting wire inside the car, which is mainly used to transmit current. According to its use, the car wire can be divided into two types: high-voltage wire and low-voltage wire. High-voltage wire is mainly used for the car's starting, charging and ignition systems, while low-voltage wire is mainly used for the car's lighting, air conditioning, audio, navigation and other equipment. The power line is a thick wire that carries large currents, while the signal line is a thin wire that does not carry electricity. For example, the cross-sectional area of the wire used in the signal circuit is 0.3 and 0.5mm2. The cross-sectional area of the wire used in the motor and actuator is 0.85 and 1.25mm2, while the cross-sectional area of the wire used in the power circuit is 2, 3, and 5mm2; and special circuits (starter, alternator, engine ground wire, etc.) have different specifications of 8, 10, 15, and 20mm2. The larger the cross-sectional area of the wire, the greater the current capacity. In addition to considering the electrical performance, the selection of wires is also subject to the constraints of the physical performance when mounted on the vehicle, so the selection range is very wide.
