All Aluminum Alloy Conductor (AAAC)

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 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 standings listed are common examples used in overhead lines. Metric (mm) sizes are also available.

Features and Benefits:

• Aluminum alloy conductors have a number of advantages over the use of the ACSR or all- aluminum conductors.
• Lower power losses than for equivalent single- aluminum-layer ACSR conductors. (The inductive effect of the steel core in the ACSR is eliminated).
• Simpler fittings than those required for ACSR.
• Excellent corrosion resistance in environments conducive to galvanic corrosion in ACSR.
• Strength and sag approximately the same as for equivalent 6/1 and 26/7 ACSR conductors.
• Outside diameters are the same as for standard ACSR conductors, permitting interchangeability of fittings.
• Greater resistance to abrasion than that for 1350 wires in all-aluminum or ACSR conductors.
