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.
Application: Overhead T&D lines-MV, HV & EHV (11 kV to 800 kV Lines).
● high Tensile strength
● better sag properties
● economic design
● best suited for transmission lines with long spans
At a temperature of 20°C (68°F), the density of hard-drawn aluminium has been taken as 2.703 g/cm3 (168.74 lb/cf) and for steel wire 7.78 g/cm3 (485.69 lb/cf).
Standard: IEC, BS, ASTM, CAN-CSA, DIN, IS, AS and relevant national and international standards.
