Description/ Specification of ACSR Conductor

ACSR, or Aluminium Conductor Steel Reinforced, is one of the conductors employed for high-capacity transmission lines of high voltage to transmit bulk power from generation stations/large sub-stations. The name itself indicates that these conductors have an aluminium strand as an outer layer while the core consists of a single or multiple strands of steel conductor based on the conductor capacity and size. Steel wires are galvanised to avoid corrosion. As steel possesses greater tensile strength compared to aluminium, it supports the centre, the principal current-carrying aluminium conductors. This avoids sagging of the conductor. This characteristic makes ACSR conductors suitable for application where a river crossing or long run with least support is required. At times the amount of required conductor is greater than can be provided in one reel. Under such circumstances, splicing or jointing is necessary. Owing to the skin effect, the majority of the current tends to concentrate and flow close to the surface of the conductor. This provides the advantage that aluminium at outer layers, being a much superior conductor than steel, conducts the bulk current, while steel at the centre provides it with the mechanical properties. ACSR conductors have lower total AC resistance and thus are effective in operation. Different compositions of aluminium and steel strands can be achieved based on the need for tensile strength and conduction capacity.
