All Aluminum Alloy Conductors Application
Used as bare overhead conductor for primary and secondary distribution. Designed for utilizing a high-strength aluminum-alloy to achieve a high strength-to-weight ratio; affords good sag characteristics.
(1)AAAC conductors are 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.
(2)The aluminum alloy conductors are used in replace of single-layer ACSR conductors to reduce power loss in overhead distribution and transmission lines,when replacing the aluminum conductor steel reinforced , the AAAC can save 5-8% of the construction cost.
(3)AAAC referred to have higher strength but lower conductivity than pure aluminum. Being lighter, alloy conductors can sometimes be used to replace the conventional ACSR.
Standards:

FEATURES
AAAC / All Aluminum Alloy Conductor Features
Aluminum alloy conductors have a number of advantages over the use of the ACSR or AAC(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.
• High tensile strength as compared to AAC conductor.
• Higher conductivity as compared to ACSR conductor.
