Aluminium Conductors Steel Reinforced (ACSR), also known as Bare aluminium conductors, are one of the most widely used conductors for transmission. The conductor consists of one or more layers of aluminium wires stranded over a high strength steel core that can be single or multiple strands depending on the requirement. There can be various stranding combinations of Al and steel wires lending flexibility to obtain suitable current carrying capacity and mechanical strength for the application.
The current carrying capacity of ACSR conductor depends upon following;
• Cross-sectional area of the conductor
• Conductor Material
• Surrounding temperature (Ambient temp.) of conductor used in transmission line
• Age of the conductor
As below is the technical table of current carrying capacity of various types of ACSR conductor;
