ACSR - Aluminium Conductor Steel Reinforced

Construction

The mixed construction of ACSR makes it a very flexible medium from a design point of view. By varyingthe relative proportions of aluminium and steel the ideal conductor for any particular application can beproduced. Generally, ACSR consists of a galvanized steel core of 1 wire, 7 wires or 19 wires surroundedby concentric layers of aluminium wire.
When a conductor with a high current carrying capacity and comparatively low strength is required, special onstructions 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 wirescan, if required, be supplied partially or fully greased.OCI ensures complete freedom from contamination by other metals during the entire manufacture ofACSR conductors.
