APPLICATION
AAAC (All Aluminum Alloy Conductor) are designed for reliable overhead power transmission and distribution in low & medium voltage electrical networks, with an exceptional strength-to-weight ratio and superior corrosion resistance. They are widely used in:
- Urban and rural power grid renovation and overhead line expansion projects
- Coastal and high-corrosion industrial area power distribution networks
- Long-span overhead transmission lines for solar & wind farm grid connection
- Rural electrification projects and secondary distribution lines
- Hilly, mountainous and high-tension overhead line installations
These conductors can be installed on overhead transmission towers, utility poles, and long-span structures, with outstanding resistance to atmospheric corrosion, mechanical fatigue, and environmental aging, delivering a longer service life than traditional AAC conductors in harsh operating environments.
CONSTRUCTION
- Conductor: High-strength heat-treated aluminum-magnesium-silicon alloy (Al-Mg-Si 6201-T81), Class 2 concentric stranded per IEC standards
- Stranding Structure: Concentric lay stranded construction, uniform lay length for consistent mechanical and electrical performance
- Surface Finish: Smooth, oxide-free surface for optimal electrical contact and enhanced corrosion resistance
- Permanent Marking: Continuous length marking, alloy grade, size and standard compliance printed along the conductor length
CHARACTERISTICS
- Voltage Rating: Suitable for LV/MV overhead lines up to 36 kV (customizable for higher voltage transmission networks)
- Temperature Rating:
- Continuous operating: 90°C
- Emergency overload: 120°C (short duration)
- Mechanical Performance: High tensile strength (min. 295 MPa for standard grade), excellent sag control for long-span installations
- Corrosion Resistance: Superior atmospheric corrosion resistance, ideal for coastal, industrial pollution, and high-humidity environments
- Electrical Performance: Stable DC resistance per international standards, excellent current-carrying capacity for efficient power distribution
- Weight Advantage: Lower density than steel-reinforced conductors, reduced tower load and lower installation cost for long-span projects
STANDARDS
- ASTM B399: Standard Specification for Concentric-Lay-Stranded Aluminum-Alloy 6201-T81 Conductors for Overhead Electrical Transmission
- IEC 61089: Round wire concentric lay overhead electrical stranded conductors
