Bare all aluminum alloy conductors (AAAC) are concentric-lay-stranded consisting of aluminum alloy 6201 wires wrapped helically around a central wire. The aluminum is heat-treated to a T81 temper to provide superior strength.
Features and Benefits
AAAC conductors provide a higher strength to weight ratio than traditional AAC conductors, and better corrosion resistance than ACSR conductors.
Applications
Stranded bare AAAC may be used for overhead line installations where the higher strength or temperature ratings of ACSR, ACCR or other types of conductors is not required, but improved sag performance to AAC is desired.
