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 where mechanical loading is moderate and long-term corrosion performance is critical.
Pure aluminum construction provides the highest conductivity among standard bare overhead conductors (approximately 61% IACS), delivering maximum current-carrying capacity with minimal line losses.
Key Advantages
- Highest Conductivity — Pure 1350-H19 aluminum delivers maximum current-carrying capacity and lowest line losses of any standard bare overhead conductor.
- Lightweight Design — Significantly lighter than ACSR or AAAC, reducing tower/pole loading, foundation costs, and installation effort.
- Excellent Corrosion Resistance — Absence of a steel core eliminates galvanic corrosion risks, making AAC ideal for coastal, industrial, and high-pollution environments.
- Optimized Sag Performance — Favorable thermal expansion characteristics ensure reliable operation under varying temperatures and loads.
- Cost-Effective Solution — Economical choice for medium to large-span distribution and transmission lines where high tensile strength is not the primary requirement.
- Superior Electrical Efficiency — Highest conductivity-to-weight ratio, improving overall system efficiency and reducing energy losses.
Construction
AAC conductors consist of bare, concentrically stranded 1350-H19 aluminum wires. The design features a straight central wire surrounded by one or more layers of helically laid wires. This construction ensures excellent flexibility, mechanical stability during installation, and uniform electrical properties along the entire length.
Main Applications
All Aluminum Conductors are widely used in:
- Medium-voltage and high-voltage overhead distribution networks in urban and rural areas
- Coastal and high-corrosion environments where steel-core conductors would be vulnerable
- Long-span crossings where weight reduction provides significant structural and economic benefits
- Urban transmission and sub-transmission lines with moderate mechanical loading
- Grid modernization projects prioritizing high conductivity and long-term corrosion performance
These characteristics make AAC particularly suitable for distribution and selected transmission projects in the Saudi Kingdom and GCC region, including coastal networks and urban grid upgrades under Vision 2030.
