AAAC-All Aluminum Alloy Conductors ASTM B 399

Our AAAC (All Aluminum Alloy Conductors) are engineered in accordance with IEC 61089 standards, offering an optimal balance of strength, lightweight design, and excellent electrical performance. Made from high-quality aluminum alloy strands, these conductors provide superior corrosion resistance and high tensile strength, making them ideal for overhead power transmission and distribution lines. The AAAC conductors deliver reliable performance in diverse environmental conditions, ensuring efficient and durable electrical infrastructure.

AAAC-All Aluminum Alloy Conductors ASTM B 399 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.
