Application and Advantages of Aluminum Alloy High Voltage Cables

China [CN]

Description: Application: Automotive aluminum alloy charging cables play an important role in modern electric vehicles, mainly due to their lightness and cost-effectiveness. With the rapid development of the new energy vehicle market, the demand for automotive cables is also increasing, especially those cable solutions that can provide better energy efficiency and reduce vehicle weight. In this case, aluminum alloy cables have become an ideal choice. The details are as follows:

Introduction: Aluminum alloy power cables are new material power cables with AA8030 series aluminum alloy materials as conductors, special roll-formed wire stranding production processes and annealing treatment and other advanced technologies. Alloy power cables make up for the shortcomings of pure aluminum cables in the past. Although the electrical conductivity of the cable has not been improved, the bending performance, creep resistance and corrosion resistance have been greatly improved, which can ensure that the cable maintains continuous performance stability when overloaded and overheated for a long time. The use of AA-8030 series aluminum alloy conductors can greatly improve the conductivity and high temperature resistance of aluminum alloy cables, while solving the problems of pure aluminum conductors and creep. The conductivity of aluminum alloy is 61.8% of the most commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, which is better than the pure aluminum standard. However, at the same volume, the actual weight of aluminum alloy is about one-third of copper. Therefore, the weight of aluminum alloy cable is about half of copper cable at the same current carrying capacity. Using aluminum alloy cable to replace copper cable can reduce the weight of cable, reduce installation costs, reduce wear of equipment and cables, and make installation easier.

Features: Aluminum alloy cable adds alloy elements such as copper, iron, magnesium, silicon, zinc, and boron 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 cable systems. In addition, the electrical properties of aluminum alloy are kept at the same level as electrical aluminum conductors, above 61% IACS.

Conductivity:

The conductivity of aluminum alloy is 61.8% of the most commonly used reference material copper IACS, and the current carrying capacity is 79% of copper, which is better than the pure aluminum standard. However, at the same volume, the actual weight of aluminum alloy is about one-third of copper. [3]. Therefore, the weight of aluminum alloy cable is about half of that of copper cable for the same current carrying capacity. Using aluminum alloy cable instead of copper cable can reduce the weight of cable, reduce installation cost, reduce wear of equipment and cable, and make installation easier.

Weight:

Under the premise of meeting the same electrical performance, the weight of aluminum alloy cable is half of that of copper core cable, its cross-section is 1.1~1.25 times that of traditional copper core cable, and its price is 15~30% lower than that of traditional copper core cable.

In summary, in the complex and rigorous modern automobile engineering, aluminum alloy charging cable has become an important material choice due to its unique advantages. From the energy efficiency improvement and environmental benefits brought by its lightweight, to its significant economic efficiency; from its electrical performance comparable to that of copper cable, to its unique advantages in mechanical performance; to its production and manufacturing process that complies with domestic and international standards and specifications, aluminum alloy cable has shown great potential in practical applications.
