ACAR
All Aluminium Conductors Alloy Reinforced (ACAR) is formed by concentrically stranded wires of aluminium on a high strength Aluminium-Magnesium-Silicon (AlMgSi) alloy core. ACAR has better mechanical and electrical properties compared to equivalent conductors of ACSR, AAC or AAAC. These conductors are extensively used in overhead transmission and distribution lines.
