Function and composition of cables for new energy vehicle parts

Product description: Automotive cables refer to wires and cables that connect various parts of a car. They are an important part of the automotive electrical system. The main function of automotive cables is to transmit electrical energy and signals to ensure the normal operation of various electronic devices.

Automotive cables are mainly composed of the following parts:

1. Conductor: The conductor is the core part of the automotive cable for transmitting electrical energy, and is mainly made of copper or aluminum. Copper conductors have good electrical conductivity and strong anti-oxidation properties, but are more expensive; aluminum conductors are relatively cheap, but have poor electrical conductivity.

2. Insulation layer: The insulation layer is a protective layer that protects the conductor and prevents current leakage. It is mainly made of materials such as polyvinyl chloride (PVC) and cross-linked polyethylene (XLPE). Insulation layers of different materials have different high temperature resistance, cold resistance, and corrosion resistance. Choosing different materials can adapt to different environmental conditions.

3. Sheath layer: The sheath layer is the outer layer that protects the cable, and is mainly made of materials such as polyvinyl chloride (PVC) and polypropylene (PP). The sheath layer can protect the cable from mechanical damage, chemical corrosion, ultraviolet rays and other factors.

4. Shielding layer: The shielding layer is located between the cable insulation layer and the sheath layer, and is mainly used to prevent electromagnetic interference and improve the quality of signal transmission. The materials of the shielding layer include aluminum foil, copper mesh, etc.

In summary, the composition and material selection of automotive cables directly affect the stability and safety of the automotive electrical system. Therefore, when designing and producing automotive cables, it is necessary to select appropriate materials and structures according to different application scenarios and requirements to ensure the normal operation and safety of the automotive electrical system.
