ACSR conductor consists of a solid or stranded steel core surrounded by  strands of aluminum (E.C. GRADE). ACSR Conductor is available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR Conductor are used for river  crossings, overhead ground wires, installations involving extra long spans etc. Against any given resistance of conductor, ACSR may be manufactured for having a wide range of  tensile strength as per requirement. The principal advantage of these conductors are high tensile strength  so that they are used for longer spans with less supports.  Due to the greater diameter of ACSR  Conductor a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage Overhead lines.
