ACSR - Aluminium Conductor Steel Reinforced Construction
The mixed construction of ACSR makes it a very flexible medium from a design point of view. By varying the relative proportions of aluminium and steel the ideal conductor for any particular application can be produced. Generally, ACSR consists of a galvanized steel core of 1 wire, 7 wires or 19 wires surrounded by concentric layers of aluminium wire.
The higher strength ACSR Conductor is used for river crossings, overhead ground wires, installations involving extra-long spans. 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 is high tensile strength so that they are used for longer spans with less supports.
