Wire harnesses ensure power and signal connections are organized and streamlined into single bundled units in addition to keeping them insulated from heat, moisture, friction and vibration. For these attributes, they are widely used in industries, with the automotive sector and its electric vehicle segment being the most popular application in recent years.
Keeping up with the miniaturization trend, aluminum is increasingly being adopted over copper, especially in the automotive industry where achieving weight reduction and improved efficiency are the top goals. While not equal to copper in terms of conductivity and mechanical properties, manufacturers rely on advancements in technology to make aluminum comparably reliable.
In China, companies in the wire harness category are developing aluminum types for high-voltage applications. Specifically, they are aiming for 1,500V to fully meet the fast-charging and high-speed data transmission requirements in EVs.
Mainstream copper-based versions are still widely available and can be customized according to buyers’ preferences on materials, connector types, and cable length and color. Suppliers ensure product quality is up to UL, CE, CSA, SAA and other industry standards. Many have ISO 9001, 14001 and IATF 16949 certifications.
Metal materials such as copper, silver and gold come from domestic providers, while plastics such as PVC, PE and PTFE may be obtained from foreign companies when specified. As for connectors, the usual sources include TE, Molex, Delphi, JST, Sumitomo and Yazaki as well as homegrown counterparts.
Prices of wire harnesses remain dependent on the cost of copper, which has been fluctuating for many years now.
