The Performance Difference Between Aluminum Alloy Cable And Copper Aluminum Cable

Because of the stable function and reasonable price, aluminum alloy cables can meet the requirements of our lives. They are generous in appearance and have outstanding water resistance. It can ensure the normal operation of the production line, but compared with copper cables, the temperature resistance of this product is somewhat different. The coefficient of thermal expansion of aluminum is much higher than that of copper. The cable factory indicated that although the aluminum alloy has been improved, it is still in use. In this process, the coefficient of thermal expansion directly leads to a vicious circle of problems after this process. The power supply will definitely be affected. For normal applications, this will be a good test. Therefore, aluminum alloy cables are not suitable for use as fire-resistant cables, and should be used with caution in densely distributed lines to avoid accidents that directly cause the entire line to be directly affected by itself or the external environment.

The cable factory pointed out that after bending and releasing copper cables and aluminum alloy cables at room temperature, the rebound angle of aluminum alloy cables is 60° of the rebound angle of copper cables. Because the aluminum alloy cable has no memory, its rebound function is better than that of the copper core cable. During the installation process, the terminal connection joint is easy to compress, which increases its tightness and improves the stability of the connection. Copper has outstanding electrical conductivity. If the aluminum alloy cable is to achieve the same current carrying capacity as the copper cable, it is necessary to add the cross-sectional area of the aluminum alloy and make it thicker. One thick and one thin, the direct result is the difference in cable bending radius. Elongation is an important target for the mechanical function of a conductor, as well as an important target for product quality and the ability to withstand external forces. The main test is to test the resistance of the metal wire. The better the patience, the greater the distortion it can withstand, and the laying will vary. Some people say that aluminum alloy is lightweight, which is also a major advantage of aluminum alloy, which saves labor.
