When it comes to reliable overhead power transmission, AAAC (All Aluminium Alloy Conductor) stands out for its durability, strength, and corrosion resistance. HNBFpower, a trusted name in the power transmission industry, provides premium-grade AAAC conductors designed for long-lasting performance in diverse environmental conditions.
What Is an AAAC Conductor?
An AAAC conductor is made entirely of aluminum alloy wires, typically an Al-Mg-Si (Aluminum-Magnesium-Silicon) alloy. Unlike traditional ACSR conductors, which have a steel core, AAAC uses the same material throughout — ensuring excellent conductivity and resistance to corrosion. It’s widely used for medium and high-voltage overhead lines and preferred in coastal or industrial areas where resistance to oxidation is crucial.
Specifications and Construction
AAAC conductors are constructed using multiple strands of hard-drawn aluminum alloy wires twisted together in concentric layers.
Key Specifications Include:
Material: Aluminum Alloy (6101-T81 or equivalent)
Conductivity: Approximately 52% IACS
Density: 2.7 g/cm³
Operating Temperature: Up to 90°C
Tensile Strength: High strength-to-weight ratio
Standard Compliance: ASTM B399, IEC 61089, BS EN 50182
The uniform construction ensures balanced mechanical properties and low sag, making it ideal for long-span transmission lines.
Characteristics of AAAC Conductors
High Corrosion Resistance:
The aluminum alloy provides exceptional resistance to rust, especially in coastal or polluted environments.Lightweight and Strong:
Compared to ACSR, AAAC offers a better strength-to-weight ratio, making it easier to handle and install.Excellent Conductivity:
Despite being slightly lower than pure aluminum, the conductivity of AAAC is sufficient for efficient power transmission.Low Sag Performance:
Due to its mechanical strength, AAAC maintains a consistent line profile under various temperature conditions.Thermal Stability:
It performs efficiently even at high temperatures, ensuring reliability during peak loads.
