AAC (All-Aluminum Conductor) cables remain one of the most widely used overhead conductors in low- and medium-voltage distribution lines. Their lightweight structure, excellent conductivity, and corrosion resistance make them a preferred choice for utilities, EPC contractors, and industrial power developers. As a global manufacturer of overhead conductors, HNBF Power provides high-performance AAC cable solutions engineered for long-term reliability in diverse climates and terrains.
What Is AAC Cable?
AAC cable is made entirely of high-purity aluminum strands, concentrically stranded to deliver high electrical conductivity and reduced line losses. Its all-aluminum design makes it lighter than steel-reinforced conductors while still offering excellent performance for short-span overhead lines.
AAC cable is commonly used in:
-
Urban and suburban distribution networks
-
Power transmission in coastal and high-corrosion areas
-
Overhead service drops
-
Electrical infrastructure requiring high conductivity with minimal mechanical load
Technical Characteristics of AAC Cable
High Conductivity
Aluminum’s superior conductivity-to-weight ratio enables efficient power transfer with minimal energy loss. AAC cables typically provide conductivity levels around 61% IACS, making them ideal for distribution networks with shorter span lengths.
Low Weight & Easy Installation
Because AAC cables have no steel core, they are significantly lighter than ACSR and other composite conductors. This reduces tower loading requirements and simplifies installation for contractors.
Corrosion Resistance
The all-aluminum structure offers exceptional corrosion resistance, especially in marine and industrial environments. This makes AAC cable a long-lasting solution for harsh terrains.
Flexible Stranding Options
AAC cables are available in multiple stranding configurations based on required ampacity, sag performance, and mechanical strength. HNBF Power produces AAC cables according to IEC, ASTM, BS, and other international standards.

Renewable energy power evacuation lines
AAC cable remains a reliable and cost-effective choice for short-distance power transmission, especially where high conductivity is more critical than mechanical strength.
Frequently Asked Questions (FAQs)
1. What is the main difference between AAC and ACSR cable?
AAC is made entirely of aluminum, while ACSR includes a steel core for higher mechanical strength. AAC is preferred for short spans, while ACSR suits long-distance transmission.
2. Is AAC cable suitable for coastal environments?
Yes. Its all-aluminum design offers excellent corrosion resistance, making it ideal for marine and industrial areas.
3. Does AAC cable support high-voltage applications?
AAC is mainly used for low- and medium-voltage distribution lines. For high-voltage or long-span installations, ACSR or AAAC is often the better option.
4. Can HNBF Power manufacture AAC cables in customized sizes?
Yes. HNBF Power provides fully customized conductor sizes, stranding structures, and packaging options for utility and industrial projects.
5. What standards do HNBF Power AAC cables follow?
Our cables meet IEC, ASTM, BS, and other international standards required in global power projects.
