All aluminum alloyConductor AAAC Tatara

Applications:

AAAC aluminum alloy conductorsare extensively used for overhead distribution and transmission lines adjacent to ocean coastlines where there can be a problem of corrosion in the steel of an ACSR construction. The aluminum alloy conductors are used in place of single-layer ACSR conductors (i.e., #6 to #4/0 AWG) to reduce power losses in overhead distribution and transmission lines. The inductive effect of the ACSR’s steel core is eliminated, hence increasing the operating efficiency of the line.

Product Construction:

Complete 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 conductoris manufactured in accordance with the requirements of the latest issue of ASTMB399. The AAAC conductor is manufactured from a heat-treated, magnesium-silicate high-strength 6201T81 aluminum alloy.

The aluminum strandsconsist of a concentric stranded cable of 7, 19, 37, 91, 127 wires. The single wires’ diameter ranges from 1.7mm to 4.77mm.
