Description
Aluminium Conductor Steel Reinforced(ACSR)
Used as bare overhead transmission conductor and as primary and secondary distribution conductor and messenger support.
ACSR conductors combine the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag and longer span lengths than obtainable with most other types of overhead conductors. The steel strands are added as mechanical reinforcement.
ACSR is a composite concentric-lay-stranded conductor. The steel strand or strands form the central core of the conductor, around which is stranded one or more layers of aluminum wires.
