It can replace part of aluminum conductors or ACSR for overhead distribution lines. Temperature for continuous use is up to 90 ºC. Temperature of heat-resistant aluminum alloy strands is up to 150 ºC and above. It has high current carrying capacity and good corrosion perfor-mance.
Aluminum Electrical Conductor AAAC Cable 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.
