ACSR, acsr conductor, overhead conductor,Aluminum 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.  When a conductor with a high current carrying capacity and comparatively low strength 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.
