Copper, Aluminium are common conductors used for electricity transmission and distribution. Hard drawn copper has significantly higher tensile strength than soft annealed copper whereas the soft annealed copper is flexible and has somewhat improved conductivity over hard drawn copper conductor. AAC, AAAC, ACSR form part of the family of Overhead Conductors, Transmission Conductors and Power Distribution Conductors. These cables are formally known as All Aluminium Conductor (AAC), All Aluminium Alloy Conductor (AAAC) and Aluminium Conductor Steel Reinforced (ACSR). These overhead aluminium conductors are used as power transmission and distribution lines.
