ACSS-Aluminium Conductor Steel Supported
is a composite concentric-lay stranded conductor with one or more layers of hard drawn and annealed 1350-0
aluminum wires on a central core of steel. In an ACSS, under normal operating conditions, the mechanical load is mainly
derived from the steel core as aluminum in fully annealed stage does not contribute much towards the mechanical strength.
Steel core wires are protected from corrosion by selecting an appropriate coating of the wire like galvanizing, mischmetal
alloy coating or aluminum clad. The type of coating is selected to suit the environment to which the conductor is exposed and operating temperature of the conductor.
ACSS with Galvanized steel, Zn-5Al mischmetal coated steel or Aluminum clad steel core (normal as well as high strength and Exhra high strength).
