Introduction: There are two main types of metal wires in automotive cable harnesses: copper and aluminum. The use of these metal wires in automotive cable harnesses involves many aspects such as current transmission, signal transmission and protection.

Description: First of all, copper wire is one of the most commonly used metal wires in automotive cable harnesses. Copper wire has very good conductivity and can withstand high current, so it is often used in electric vehicles to connect high-power circuits such as motors, battery packs and charging systems. In addition, copper wire also has good corrosion resistance and reliability, and can operate stably for a long time in harsh environments.

Secondly, aluminum wire is another commonly used metal wire for automotive cable harnesses. Compared with copper wire, aluminum wire has slightly worse conductivity, so aluminum wire is often used to connect low-power circuits, such as lights, horns, air conditioners, etc. In addition, aluminum wire is lighter than copper wire and relatively cheaper, which can reduce the cost of automotive cable harnesses to a certain extent.

In addition, metal wires also play an important role in the protection of automotive cable harnesses. For example, vehicles are subject to various external interferences and damages during driving, such as friction, vibration, collision, etc., which can cause damage and failure of cable harnesses. In order to protect the automotive cable harness, metal materials such as metal braided layers or aluminum foil layers need to be added to the cable harness to provide additional strength and shielding effect to prevent the cable harness from external interference.

In summary, metal wires are one of the indispensable components in automotive cable harnesses. Their quality and use have an important impact on the performance and safety of the entire vehicle.
