Aluminium Conductor Steel Reinforced

Construction

The mixed construction of ACSR makes it a very flexible medium from a desigh point of view. By varying the relative proportins 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 .

When a conductor with a high current carrying capacity and comparatrively low strengh is required , special constructions are available with a high aluminium content.

Protection against Corrosion

A coating of non-oxidizing grease is normally applied to the steel cores of all conductors , in addition to the protection offered by the galvanizing of the steel wires. One or more layers of the aluminium wires can , if required , be supplied partially or fully greased.
