Among the many cables, copper cable has undoubtedly become a better choice. There are three main reasons: 1. Copper has a high conductivity, about 1.57 times that of aluminum. Copper's excellent conductivity can make the cable is not easy to heat, to ensure the safety of the power supply and energy saving. 2. the same cross-section of copper cable and aluminum cable, copper cable has a greater current-carrying capacity, voltage loss and fault rate is lower, can meet the automobile manufacturers huge power supply, to ensure that the equipment uninterrupted operation of laying an important foundation. 3. copper has a strong antioxidant properties. Even if copper is oxidized, the copper oxide generated is still an excellent conductor, which ensures the electrical connection performance of joints and terminals. Aluminum oxidation generated by the aluminum oxide is an insulator, will affect the conductivity of the joints or terminals, exacerbated by the joints or terminals to heat up the cable failure, or even fire. In addition, copper cable also has superior high temperature performance. Aluminum melting temperature of 660 ° C, while the copper up to 1080 ° C, even in a high-temperature environment, copper cables can still maintain the function of the power, which for the automotive manufacturers to achieve the safety of electricity to provide another important guarantee.
