Automotive Wire is a kind of connection wire inside the car, which can be used for current transmission of batteries, meters, lights, etc. The requirements of automotive wire tend to be cold-resistant and high-temperature resistant, so better rubber is needed to meet this requirement. Automobile wires are all copper multi-core soft wires. Several or even dozens of soft copper wires are wrapped in insulating tubes, which are soft and not easy to break. There are two types of automotive wires, high-voltage wires and low-voltage wires, both of which are processed with copper multi-core flexible wires. The cross-sectional area of the wire is mainly selected according to its working current.
