Answer: The widespread use of aluminum conductors like ACSR is due to a combination of their physical and economic advantages. Aluminum is lightweight and highly conductive, making it an efficient material for carrying electrical current. When combined with a galvanized steel core in an ACSR conductor, the product offers exceptional tensile strength, which allows for longer spans between support towers. This reduces the number of towers needed for a project, significantly lowering both material and installation costs. Additionally, the larger diameter of ACSR conductors helps to reduce electrical losses from the corona effect on high-voltage lines.
