AAAC (All Aluminium Alloy Conductors) Product
AAAC (All Aluminium Alloy Conductors)
Product Overview
As an experiencedbare conductor supplier,Hebei Yingshang Aluminum Industrymanufactures high-qualityaaac conductor(all aluminium alloy conductor)for modern overhead transmission and distribution systems. AAAC conductors are widely applied in medium to high-voltage power lines, regional distribution networks, and renewable energy grid-connection projects where corrosion resistance, mechanical strength, and long-term reliability are critical.
Produced from heat-treated aluminium alloy (commonly 6201 or equivalent), AAAC conductor offers a well-balanced combination of strength, conductivity, and lightweight design. Compared with traditional AAC and steel-reinforced conductors, AAAC provides improved tensile performance and superior resistance to environmental corrosion, making it a proven solution for utilities, EPC contractors, and power grid operators worldwide.
Core Characteristics of
High Mechanical Strength
AAAC conductor is manufactured using high-strength aluminium alloy wire, providing significantly higher tensile strength than pure aluminium conductors. This allows the conductor to withstand greater mechanical tension and supports longer spans, making it suitable for complex terrain, urban networks, and demanding installation environments.
Reliable Electrical Conductivity
Although aluminium alloy has slightly lower conductivity than pure aluminium,all aluminium alloy conductorstill delivers excellent electrical performance that fully meets overhead power transmission requirements. Its optimized strength-to-conductivity ratio ensures efficient and stable power delivery.
Excellent Corrosion Resistance
Aluminium alloy naturally resists atmospheric corrosion and does not rust. AAAC conductor is particularly suitable forcoastal areas,industrial pollution zones, andhigh-humidity environments, where steel-cored conductors may suffer from accelerated degradation.
Electrical Performance
For circular aluminium alloy wires with the same nominal cross-sectional area, DC resistance at20 °Cvaries according to conductor size—larger cross-sections result in lower DC resistance.
EachAAAC conductoris designed with a defined current-carrying capacity based on alloy composition and conductor cross-section.For example, a25 mm² aluminium alloy conductortypically supports a current of approximately110 Aunder standard operating conditions.
These electrical characteristics ensure consistent transmission performance across different voltage classes and load conditions.
