Strand Conductor Composite Overhead Ground Wire for High Pressure Voltage Cable

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.

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, superior to the pure aluminum standard. But in the same volume, the actual weight of aluminum alloy is about one-third of that of copper. Therefore, the weight of aluminum alloy cable is about half that of copper cable at the same current carrying capacity. Replacing copper cable with aluminum alloy cable can reduce cable weight, installation cost, wear of equipment and cable, and make installation easier.
