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
IEC 61089
Construction
ACSR is a composite conductor consisting of seven or more aluminium and galvanized steel wires built up in concentric-lay-stranded layers.
Used as bare overhead transmission cable and as primary and secondary distribution cable. ACSR provides optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.

FAQ
What is bare ACSR conductor?
ACSR means Aluminium Conductor Steel Reinforced. It is a stranded bare overhead conductor composed of aluminium strands for electrical conduction and a central steel core for mechanical reinforcement.
What are the main applications of IEC 61089 compliant ACSR?
It is primarily used for overhead power transmission lines, long-span distribution lines, river-crossing lines and overhead lines in areas requiring high mechanical strength.
What routine tests are required for ACSR per IEC 61089?
Required tests include dimensional check, DC resistance test, tensile strength test, elongation test and visual inspection of surface and stranding structure.
