The Aluminum Alloy Cable is added with alloying elements such as copper, iron, magnesium, silicon, zinc and boron in the electrical aluminum. At the same time, the mechanical properties of the aluminum alloy conductor are greatly improved by the process adjustment, and the elongation of the pure aluminum conductor is avoided, and the creep resistance is avoided. The problem of poor performance and poor flexibility increases the connection reliability of the cable system. In addition, the electrical properties of the aluminum alloy are kept flat with the electrical aluminum conductor, above 61% IACS.
The alloy power cable compensates for the shortcomings of the previous pure aluminum cable. Although the electrical conductivity of the cable is not improved, the bending performance, creep resistance and corrosion resistance are greatly improved, and the cable can be kept continuous during long-term overload and overheating. Stable performance, using AA-8030 series aluminum alloy conductor, can greatly improve the electrical conductivity and high temperature resistance of aluminum alloy cable, and solve the problems of electrochemical corrosion and creep of pure Aluminum Conductor.
The electrical conductivity of High Quality Aluminum Alloy Cable is 61.8% of the copper IACS, the most commonly used reference material, and the current carrying capacity is 79% of copper, which is superior to the pure aluminum standard. But at the same volume, the actual weight of the aluminum alloy is about one-third that of copper . Therefore, the weight of the aluminum alloy cable at the same current carrying capacity is about half that of the copper cable. The replacement of copper cables with aluminum alloy cables can reduce cable weight, reduce installation costs, reduce equipment and cable wear, and make installation easier.
