Aluminium conductors are widely used in transmission and distribution systems due to their unique properties, such as being lighter, cheaper, and having similar resistance to copper. Aluminium Conductor Steel Reinforced (ACSR) and All-Aluminium Alloy Conductors (AAAC) are famous conductors used in different applications. In this article, we will explore the difference between Aluminium Conductor Steel Reinforced (ACSR) Conductors and All-Aluminium Alloy (AAA) Conductors and Which one to choose between them.
ACSR, or Aluminium Conductor Steel Reinforced Conductor, is used for overhead power lines. From the outside, they contain a layer of aluminium wires wrapped around a strong steel core. This helps the conductor perform its job efficiently and keeps it light, making it easier to install and maintain. The steel core provides them strength from the inside, so they must be installed overhead. Apart from the inside and outside design, many advantages and applications of ACSR Conductors help you choose the best ACSR Conductors for the transmission lines.
All Aluminium Alloy (AAA) Conductors are made of a potent mix of Aluminium, Magnesium, and Silicon. They are light in weight yet just as strong and capable of carrying current as other options.
After briefly discussing both conductors, let's hop into the difference between the two.
Aspect | Aluminium Conductor Steel Reinforced (ACSR) Conductors | All-Aluminium Alloy (AAA) Conductors |
Construction | ACSR conductors are made from a combination of aluminium and steel. | AAAC conductors are made entirely of aluminium alloy. |
Weight | ACSR conductors are heavier compared to AAA conductors. | AAA conductors are much lighter than ACSR conductors. This feature makes them easier to transport and install. |
Price | ACSR conductors are expensive. | AAA conductors are less expensive. |
Corrosion Resistance | ACSR conductors have poor corrosion resistance due to the combination of aluminium and steel. | Due to their aluminium composition, AAA conductors have excellent corrosion resistance, especially in areas like the sea coast and polluted industrial areas due to the absence of steel core. |
Applications | ACSR conductors are preferred for electrical power transmission over long distances as they are the best choice for long overhead line spans. | AAA conductors are widely used for overhead transmission and distribution lines. |
Choosing the right conductor between them depends on your project requirements, needs, and applications. In electrical projects, a range of conductors are available in the market, but two commonly used ones are ACSR and AAAC conductors. Each has pros and cons, so picking the right type is crucial for your project. Always consult with a reputable and top conductor manufacturer who understands your specific project's requirements and can recommend the best solution.
