Bare AAAC conductors are intended for use as overhead primary or secondary distribution conductor. Since these conductors are manufactured with high strength aluminum, they are designed for longer spans and lower sag as compared to AAC (with 1350 aluminum). Abrasion resistance is also improved as compared to AAC since AAAC uses a harder aluminum alloy. This type of conductor is suitable for installation in saltwater environments due to the improved corrosion resistance. The DC resistance of an AAAC conductor is approximately the same as for an ACSR conductor of the same diameter.

Dimensions and weights are subject to standard manufacturing tolerances and are subject to change without notice.
Resistance is calculated using metal conductivity of 61.2% IACS for EC (1350) at 20ºC and 8% IACS for steel at 20ºC.
Ampacities are based on 75ºC conductor temperature, 25ºC ambient, 2 ft/s wind, full sun, an emissivity of 0.5 and a coefficient of solar absorption of 0.5, at sea level.
