AAC (All-Aluminium Conductor) remains one of the most widely used overhead conductors for low- to medium-voltage distribution lines, especially in urban and coastal regions where corrosion resistance and lightweight performance are essential. As utilities expand grids and industries demand higher reliability, choosing a technically optimized AAC conductor becomes critical. HNBF Power, a global manufacturer of overhead conductors, delivers engineered AAC solutions that meet international standards and ensure long-term system performance.

What Is an AAC Conductor?

AAC conductor is made entirely of hard-drawn, high-purity aluminium strands. Its all-aluminium structure provides excellent conductivity, low weight, and strong resistance to environmental degradation. Because it contains no steel reinforcement, AAC is best suited for shorter spans, densely populated areas, and regions requiring maximum corrosion protection—such as coastal zones.

Key Technical Features of AAC Conductors

1. High Electrical Conductivity

AAC offers superior conductivity due to its 99.5%+ pure aluminium composition. This makes it ideal for distribution lines where efficient current flow and minimal power loss are required.

2. Lightweight Construction

Its low mass simplifies installation, reduces tower loading, and enables the use of lighter support structures—benefits particularly appreciated in urban power network upgrades.

3. Excellent Corrosion Resistance

With no steel core, AAC is naturally resistant to corrosion caused by moisture or salt. This extends service life and reduces maintenance costs for coastal and tropical regions.

4. Flexible Stranding Options

HNBF Power manufactures AAC conductors in various strand configurations (7, 19, 37, 61, etc.), enabling precise selection based on mechanical strength, sag performance, and system requirements.

Applications of AAC Conductors

  • Urban distribution networks where short spans and high conductivity are needed

  • Coastal and marine environments requiring enhanced corrosion resistance

  • Industrial and commercial power distribution

  • Reinforcement or upgrading of existing overhead lines

  • Areas with lightweight support structures or restricted tower height

FAQs About AAC Conductors

1. Is AAC suitable for long-span transmission lines?

AAC is typically used for short spans. For long spans requiring higher tensile strength, AAAC or ACSR is preferred.

2. How does AAC differ from AAAC?

AAC is made of pure aluminium, while AAAC uses aluminium alloy. AAAC has better mechanical strength but slightly lower conductivity.

3. Can AAC be used in heavily polluted industrial areas?

Yes. Its corrosion resistance makes it suitable for both coastal and polluted industrial atmospheres.

4. Does AAC require regular maintenance?

AAC has low maintenance requirements due to its simple structure and resistance to corrosion.

5. What standards does HNBF Power follow for AAC?

HNBF Power manufactures AAC conductors according to IEC, ASTM, BS, and customer-specified standards.
