Aluminium Conductor Steel Reinforced (ACSR)

Aluminium Conductor Steel Reinforced (ACSR) is concentrically stranded conductor with one or more layers of hard drawn electrolytic grade aluminium wire on galvanized high tensile steel wire core. The core can be single wire or stranded depending on the size of the conductor. Steel core wire is galvanised for corrosion protection. The weight of zinc coating per unit length of steel core wire is dependent on the standard adopted. Additional corrosion protection is available through the application of grease to the core.

The proportion of steel and aluminium in an ACSR conductor can be selected based on the mechanical strength and current carrying capacity demanded by each application.

ACSR conductors are recognized for their record of economy, dependability and favourable strength / weight ratio. ACSR conductors combine the light weight and good conductivity of aluminium 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.

ACSR is manufactured and packed in non-returnable wooden reels as per the specification or customer requirement.


    • high Tensile strength

    • better sag properties

    • economic design

    • best suited for transmission lines with long spans


ACSR manufactured by Anam Electrical Manufacturing Company meets or exceeds the requirements of all international standards such as ASTM, AS, BS, BIS, CSA, DIN, IEC, NFC, SS, etc.
