AAC Conductor:
AAC Conductor is the abbreviation for All Aluminum Conductor, It is a type of overhead transmission line conductor widely used in the field of power transmission. It is made up of high-purity aluminum wires stranded together, without steel core or other metal materials. Due to its light weight and corrosion-resistant characteristics, it has become the preferred solution for urban distribution networks and special environmental power transmission.
Core Features and Structure of AAC Conductor:
High purity aluminum wire: using electrolytic aluminum with purity of ≥ 99.7% (usually 1350-H19 hard aluminum alloy), which has good conductivity and mechanical strength.
Stranded structure: strands of aluminum wire stranded form in a conductor through concentric opposite lay. Common include 7 strands, 19 strands, 37 strands, etc. The cross sectional area can be customized according to current requirements (such as 50mm ², 120mm ²)
Light weight: With a density only 1/3 of steel, it significantly reduces the load-bearing pressure on towers, it is suitable for urban narrow spaces or short span distribution lines.
Excellent corrosion resistance: The naturally formed oxide film on the surface of aluminum can resist acid rain and salt spray, especially suitable for high corrosion environments such as coastal areas and industrial zones.
High conductivity efficiency: The conductivity is about 61% IACS (International Annealed Copper Standard)
Limitation of AAC Conductor:
Low tensile strength: no steel core, span shall not exceed 200 meters, not suitable for long-distance high-voltage transmission.
Easy to creep and relax: Long term stress may cause slight elongation of the wire, and regular monitoring of sag changes is required.
Main Application of AAC Conductor
1
Urban power distribution network:
2
Coastal and industrial areas
3
High-voltage transmission network
Comparison with other conductor such as AAAC ACSR
Summary
AAC Conductor occupies an important position in the field of medium voltage distribution due to its light weight, corrosion-resistant, and low-cost advantages, especially suitable for the power transmission needs of densely populated urban areas and special environments. When making a selection, it is necessary to consider the span, corrosion level, and budget comprehensively. If necessary, it can be combined with metal fittings such as shock absorbers and spacers to enhance stability.
