ACSR conductors consist of a solid or stranded steel core surrounded by strands of aluminum (E.C. GRADE). ACSR conductors are available in a wide range of steel, containing carbon from 0.5% to 0.85 %. The higher strength ACSR conductors 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 the 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 conductors a much higher corona limit can be obtained causing big advantages on high as well as extra high voltage overhead lines.
