The working principle of automotive cables is to transmit electrical energy through the conduction of current inside the conductor.
As an important part of the automotive electrical system, the basic principle of automotive cables is not complicated. Their main function is to transmit current from the power source to the various components in the electrical system, so as to ensure that these components can work properly. This transmission process relies on the conductors in the cable, which are usually made of highly conductive materials such as copper or aluminum, and they are responsible for carrying current. To prevent current leakage and external interference, these conductors are wrapped with insulating materials such as polyvinyl chloride (PVC) or polyethylene (PE). This structure not only ensures the effective transmission of current, but also provides the necessary protection to prevent current leakage and short circuit.
In addition, the insulation layer of automotive cables plays a key role in protecting the circuit. The insulation layer can prevent the loss of current and correctly transmit the current to the destination, thereby protecting the circuit from damage. This dual role - transmitting power and protecting the circuit - makes automotive cables an indispensable part of the automotive electrical system.
In new energy vehicles, cables are used in a wider range of fields. In addition to the traditional power transmission function, they also undertake tasks such as data transmission and signal transmission. The composition of these cables is more complex, including high-voltage cables, connectors, protective materials, etc., ensuring the high performance and safety of new energy vehicles12.
