Aluminum conductor steel reinforced (ACSR) cable is a specific type of high-capacity, high-strength stranded cable typically used in overhead power lines. Their outer strands are aluminum, chosen for its excellent conductivity, low weight and low cost. The center strand is of steel for the strength required to support the weight without stretching the aluminum due to its ductility. This gives the cable an overall high tensile strength. This ACSR is widely used in power transmission lines with various voltage levels. They are highly acknowledged for their good characteristics such as simple structure, convenient installation and maintenance, low cost for the line, etc.
