ACSR (Aluminum Conductor Steel Reinforced):

1). Standard: IEC61089, BS215 part2, ASTM B232, DIN48204, BS EN50182

2). Specification: ACSR is a concentrically stranded conductor composed of one or more layers of hard drawn electrical purposed aluminium wire stranded with a zinc-coated steel core. The core may be single wire or stranded depending on the size.

The proportions of aluminium and steel can be varied to obtain the relation between current-carrying capacity and mechanical strength best suited to each application.

3). Application: Aluminum conductor steel reinforced is used as bare overhead transmission conductor and as primary and secondary distribution conductor. ACSR offers optimal strength for line design. Variable steel core stranding enable desired strength to be achieved without sacrificing ampacity.
