AACSR Conductor is also called All Aluminum Alloy Conductors Steel Reinforced a concentrically stranded conductor composed of one or more layers of Aluminium-Magnesium-Silicon alloy wire stranded over a high-strength zinc coated (galvanized) steel core. The steel core provides support and mechanical strength for the conductor, while the outer strand of aluminum alloy carries the current. Therefore, AACSR has high tensile strength and good conductivity. It also has good corrosion resistance, light weight, and a long service life.
