Abstract: The weight of fuel vehicle harness weight is about 30 kg and the purchasing cost is about 4 000 RMB, if use aluminum conducting wire instead of copper wire to make wiring harness, it will reduce the weight, improve fuel economy, improve emissions and reduce the cost of wiring harness. However, there are still some problems in the process of aluminum conducting wire crimping, welding, wiring assemble process and so on. In order to solve these problems and popularize the aluminum wire harness, some suppliers have also adopted new processes, new equipment and computer-aided design optimization, etc. These new technologies can effectively improve the existing problems of aluminum conducting wire, and create the conditions for the popularization of aluminum conducting wire. At the end of this paper, a simple prospect of the future use of aluminum conducting wire is made.
