AAC–ASTM-B All Aluminium Conductor
AAC (All Aluminum Conductor)** is made of high-purity aluminum (at least 99.7%), which has the advantages of light weight, good electrical conductivity, and strong corrosion resistance, but has low strength and is suitable for short-distance transmission lines and cities distribution network.
AAAC-ASTM-B All Aluminium Alloy Conductor
AAAC (Aluminum Alloy Conductor)** is made of aluminum alloy and has higher strength than pure aluminum (AAC). It has a good balance of strength, weight, conductivity and corrosion resistance, and is suitable for medium-distance transmission lines and rural power grid construction.
ACSR-ASTM-B Aluminium Conductor Steel Reinforced
ACSR (Steel Core Aluminum Alloy Stranded Wire)** is composed of steel core and aluminum alloy stranded wire. It has the highest strength and is suitable for special environments such as long-distance transmission lines, high-voltage transmission lines and crossing rivers.
ACAR-ASTM-B Aluminum Conductor, Alloy Reinforced
ACAR conductor is formed by wrapping strands of high purity aluminum (aluminum 1350) on high strength Aluminum-Magnesium-Silicon alloy (6201 aluminum alloy) core. ACAR has better electrical as well as mechanical properties than equivalent ACSR conductors. ACAR conductors may be used in overhead transmission as well as distribution lines.
When selecting a conductor type, factors such as line length, voltage level, environmental conditions, and cost should be considered.Quick Quote
- AAC: Lightweight, economical, used for short distances.
- AAAC: Good strength, light weight, suitable for medium distance routes.
- ACSR: Strongest, used for long distance and high voltage lines.
- ACAR: Balanced Strength & Weight, Ideal for Long Spans with Moderate Tension.

Aluminum vs. Copper in Overhead Power Cables
Copeer and aluminum are two common types of electricity conductors in electrical cables. Power transmission lines span for hundreds of meters between the towers, so overhead cables have to be cost-efficient. Copper wires can be used in overhead wires to a satisfactory outcome. However, aluminum power cables are two times lighter compared to their copper counterparts and six times cheaper while maintaining the same resistance rate.
These properties make aluminum the best material for high-voltage transmission lines on the market, as overhead power cable has to be light and flexible in addition to being durable. Aluminum is a malleable material that is less prompt to compression stress compared to copper. This is a clear benefit as overhead cables are subjected to such stress. Utility companies have used aluminum since the beginning of the 20th century.
Today, about 13 percent of the aluminum produced is utilized in the energy sector. Aluminum wires have the perfect strength to weight ratio and are cost-efficient because they are not labor-intensive and save construction time.
