Aluminium Alloy Conductor (AAC) plays a pivotal role in modern overhead power transmission systems. Known for its excellent conductivity, lightweight design, and corrosion resistance, AAC conductors are widely preferred in urban and rural power distribution networks. HNBF Power, a global leader in overhead conductor manufacturing, offers high-quality AAC conductors engineered to meet international standards, ensuring optimal performance for engineers, procurement professionals, and utility companies.
What is an AAC Conductor?
AAC (All Aluminium Conductor) is a type of overhead electrical conductor composed entirely of pure aluminium strands. Unlike ACSR or AAAC, AAC conductors do not have a steel core, making them lighter while maintaining excellent electrical conductivity. These properties make AAC conductors ideal for low and medium-voltage distribution lines, where mechanical strength requirements are moderate, and lightweight conductors are preferred.
Key Technical Features:
Material: 1350-H19 or equivalent high-purity aluminium
High Conductivity: Up to 61% IACS (International Annealed Copper Standard)
Lightweight Design: Reduces the mechanical load on towers and poles
Corrosion Resistance: Aluminium naturally forms a protective oxide layer
Standard Compliance: ASTM B231 / IEC 61089
Advantages of AAC Conductors
1. Lightweight and Easy to Handle
The absence of a steel core significantly reduces weight, making installation faster and safer for line engineers.
2. Superior Electrical Performance
AAC conductors offer excellent conductivity with minimal line losses, ensuring efficient power transmission across long distances.
3. Corrosion Resistance
Ideal for environments with moderate exposure to atmospheric pollutants, AAC conductors resist corrosion, extending operational life.
4. Cost-Effective Solution
Due to their lightweight nature and low maintenance requirements, AAC conductors are a cost-efficient option for power utilities and contractors.
Applications of AAC Conductors
Urban and rural low-voltage distribution networks
Overhead lines in residential and commercial areas
Temporary and permanent utility networks where weight reduction is crucial
