2. Overview of AAAC and ACSR

2.1 Historical Background

Aluminum Alloy Conductors (AAAC) and Aluminum Conductor Steel Reinforced (ACSR) are widely used in power distribution and transmission. ACSR has been a traditional choice for many years due to its high tensile strength, achieved by combining aluminum with a steel core. However, the development of high-strength aluminum alloys has led to the increasing adoption of AAAC, which offers several advantages over ACSR.

2.2 Composition and Properties

AAAC is composed of an aluminum-magnesium-silicon alloy, providing a uniform structure with excellent mechanical and electrical properties. In contrast, ACSR consists of an aluminum outer layer surrounding a steel core, which can lead to issues related to differential expansion and corrosion.
