What is the difference between AAC and ACSR?

The primary distinction between ACSR (Aluminum Conductor Steel Reinforced) and AAC (All Aluminum Conductor) is found in their composition and design:

1. Construction: While ACSR conductors are composed of several layers of aluminum wire encircling a central steel core, AAC conductors are merely composed of stranded aluminum wires.

2. Steel Core: The steel core of ACSR conductors gives the conductor stability and mechanical strength. The steel core strengthens the conductor’s total tensile strength and aids in its resistance to mechanical loads, drooping, and stretching.

3. Electrical Conductivity: The conducting elements in both AAC and ACSR conductors are made of aluminum. Because of its high electrical conductivity, aluminum can transmit power effectively. AAC and ACSR conductors are similar to one another in terms of electrical conductivity.

4. Mechanical Strength: Because ACSR conductors contain a steel core, they are much stronger mechanically than AAC conductors. Because of their higher tensile strength due to the steel core, ACSR conductors are better suited for applications with larger mechanical stresses and spans, including long-distance power transmission lines.

5. Load-Carrying Capacity: Compared to AAC conductors, ACSR conductors can carry more loads due to their steel core. The steel component gives the conductor more strength and load-bearing capacity, enabling it to carry heavier electrical loads over greater distances.

6. Applications: Because mechanical loads are reduced in short transmission distances and low voltage distribution lines, AAC conductors are frequently utilized in these situations. ACSR conductors are commonly utilized in scenarios requiring greater mechanical strength, such as long-distance power transmission, and high-voltage transmission lines.

When choosing between AAC and ACSR conductors, it’s critical to take into account the particular requirements of the power system, including voltage level, transmission distance, mechanical stress considerations, and cost considerations. AAC conductors have a lesser mechanical strength yet are more affordable and lightweight. Because of the steel core, ACSR conductors have a better mechanical strength but are usually more expensive.
