Application
IEC 61089 covers round wire concentric lay overhead electrical stranded conductors—specifically AAC, AAAC, ACSR, and ACAR,used for overhead power transmission and distribution lines.
Standard
Construction
Aluminium Conductor Alloy Reinforced (ACAR) is formed by concentrically stranded wires of Aluminium on high strength Aluminium alloy core.

FAQ
ACAR stands for Aluminium Conductor Alloy Reinforced. It is a stranded bare overhead conductor using aluminium alloy strands as the reinforcing core instead of steel, combined with conductive aluminium wires.
Yes. IEC 61089 applies to all round wire bare overhead conductors, including ACAR, AAC and ACSR. It sets unified requirements on dimensions, performances and test rules for ACAR.
Yes. Compared with conventional ACSR, ACAR has excellent anti-corrosion performance, making it a preferred choice for coastal, industrial and humid corrosive areas.
