Aluminum alloy cables add copper, iron, magnesium, silicon, zinc, boron and other alloy elements to electrical aluminum. At the same time, through process adjustment, the mechanical properties of aluminum alloy conductors are greatly improved, avoiding the problems of low elongation, poor creep resistance and poor flexibility of pure aluminum conductors, and increasing the connection reliability of the cable system. In addition, keep the electrical performance of aluminum alloy equal to that of electrical aluminum conductor, which is above 61% IACS.
