All Aluminum Conductor (AAC) is a high-conductivity, bare overhead conductor manufactured entirely from concentrically stranded 1350-H19 grade aluminum wires. With no steel core, AAC offers excellent electrical performance, lightweight construction, and superior corrosion resistance, making it the preferred choice for overhead transmission and distribution lines in environments where mechanical loading is moderate and corrosion resistance is a priority.
Key Advantages
- Highest Conductivity: Pure aluminum construction delivers maximum current-carrying capacity with minimal line losses.
- Lightweight Design: Significantly lighter than ACSR or AAAC conductors, reducing tower loading and installation costs.
- Excellent Corrosion Resistance: No steel core eliminates galvanic corrosion concerns, ideal for coastal, industrial, and polluted areas.
- Low Sag Performance: Optimized thermal expansion characteristics for reliable operation under varying temperatures.
- Cost-Effective: Economical solution for medium-span distribution and transmission lines.
Construction
AAC conductors consist of bare, concentrically stranded aluminum wires. The design features a straight central wire surrounded by one or more layers of helically laid wires, ensuring excellent flexibility, stability, and uniform electrical properties.
Main Applications
All Aluminum Conductors are widely used in:
- Medium-voltage and high-voltage overhead distribution networks
- Urban and rural power transmission lines
- Coastal and high-corrosion environments
- Long-span crossings where weight reduction is beneficial
Manufacturing Standard
Produced in full compliance with ASTM B231 / B231M-04, ensuring consistent quality, dimensional accuracy, and electrical performance.
Technical Specifications (ASTM B231 – Representative Sizes)
(A full range from small distribution sizes to large transmission conductors is available.)
Packaging
AAC conductors are supplied on high-quality wooden drums أو plywood drums for safe transportation, storage, and on-site handling. Custom drum sizes and packaging options are available upon request.
All Aluminum Conductor (AAC) provides an optimal combination of high conductivity, light weight, and corrosion resistance, making it the ideal choice for cost-effective and reliable overhead power lines.
