Application
IEC 61089 covers round wire concentric lay overhead electrical stranded conductors—specifically AAC, AAAC, ACSR, and ACAR,ACS used for overhead power transmission and distribution lines.
Due to its excellent characteristics, this product is used extensively in the cable industry for the manufacturing of Optical Ground Wire (OPGW), conventional stranded earth wired and steel reinforced cores for phases conductors, all to be used in overheads lines. Also, it can be used in alternative applications an helical hardware for overhead lines or those where the resistance to the corrosion is an important factor.
Standard
Construction
Bare concentric-lay-stranded conductors made from bare, hard-drawn, round, aluminum clad steel wires for general use of electrical purposes. Conductors are classified as follows: 14 % conductivity, 20.3 % conductivity, 27 % conductivity, 35 % conductivity, 40 % conductivity.

FAQ
ACS stands for Aluminium Clad Steel conductor. It is a bare overhead conductor made of steel wire coated with a layer of aluminium, featuring both high mechanical strength and electrical conductivity.
ACS combines ultra-high tensile strength, good corrosion resistance and stable electrical performance. It is lightweight and suitable for harsh mechanical load conditions.
ACS is single aluminium-clad steel wire, while ACSR is aluminium strands with a steel core. ACS has much higher strength but lower conductivity, mainly used for ground wires rather than main power lines.
