Overhead Transmission All Alloy Aluminum Bare Conductor AAAC Conductor
AAAC is a high strength aluminum alloy, concentric-lay-stranded conductor. It is similar in construction and appearance to the AAC all-aluminum conductor.
The AAAC conductor is manufactured in accordance with the requirements of the latest issue of ASTM B399. The AAAC conductor is manufactured from a heat-treated, magnesium-silicide high-strength 6201-T81 aluminum alloy.
The aluminum strands consist of a concentric stranded cable of 7, 19, 37 or more wires. The sizes and strands listed are common examples used in overhead lines. Metric (mm) sizes are also available.

5. Drawing:
The flexibility in using conductors with Al alloy 6201 allow optimized characteristics for transmission and distribution line projects wich require suitable mechanical strength and electrical conductivity. It is a very interesting option, which must be carefully evaluated in order to achieve the following benefits:
All benefits mentioned above contribute to reduce costs in a project.
Basically, the material is an Alloy with Magnesium/Silicon-added providing approximately twice of mechanical strength, compared to Al 1350, used in ACSR cables.
Its major difference in respect to other alternative alloys is the thermal treatment method, solubilization before drawing, which provides to material a significant increase of resistance to corrosion.
The higher surface hardness of the Al Alloy 6201, twice as much as Al 1350, gives to conductors a higher resistance to abrasion when compared to others alloys.
