What is the Main Difference Between AAC Conductor and ACSR Conductor?

ACSR Conductor vs AA Conductor Difference

The efficiency and reliability of electrical transmission systems heavily depend on the type of conductors used. Among the various types of conductors, All Aluminium Conductor (AAC) and Aluminium Conductor Steel Reinforced (ACSR) are widely utilized in power distribution networks. Understanding the differences between these two types of conductors is essential for selecting the appropriate conductor for specific applications. This article provides a detailed comparison between AAC and ACSR conductors, focusing on their composition, strength, conductivity, applications, and other critical factors.

What is ACSR Conductor: Advantages, Applications and More

Feature	AA Conductor (All Aluminium Conductor)	ACSR (Aluminium Conductor Steel Reinforced)
Composition	Made entirely of Aluminium	Made of Aluminium and Steel
Weight	The weight of All Aluminium Conductor is lighter than ACSR Conductor.	ACSR Conductor is heavier than the AA Conductor.
Strength	Lower tensile strength.	The strength of Aluminium Conductor Steel Reinforced.
Corrosion Resistance	Good corrosion resistance.	High corrosion resistance.
Applications	All Aluminium bare conductors are used for aerial distribution lines with short spans, aerial feeders, and substation bus bars.	ACSR conductors are ideal for long overhead power lines and are widely used for electrical transmission over long distances due to their strength and durability.
Installation	Easier to install due to its lightweight nature.	ACSR conductors require more effort and resources to install because of their increased weight.
Cost	Generally more cost-effective due to its all-aluminum composition.	ACSR Conductors are costly.
