Aluminum Clad Composite Overhead Ground Wire for Electric Transmission

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. [3] 。 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.
