AAAC – All Aluminum Alloy Conductor is used for primarily and secondary overhead transmission and distributionservices. AAAC conductor is designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio and better sag characteristic. AAAC conductor has a higher resistance to corrosion than ACSR.
AAAC conductor is a concentric lay stranded conductor consisting of Aluminum Alloy 6201-T81 wires, similar in appearance to a 1350 grade aluminum conductor.
DC resistance at 20°C of the 6201-T81 alloy has a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
