Aluminium Conductors, Steel-Reinforced (ACSR) is a concentric-lay-stranded conductor consisting of galvanized steel central core with one or more layers of hard drawn stranded Aluminium wires laid helically over the steel core. Steel core wires are protected from corrosion by galvanization. The core can be single wire or stranded depending on the size of the conductors.ACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.
The ACSR conductor can, against any given resistance, be manufactured to different tensile strengths, so a high tensile strength combined with its lightweight properties means it can cover longer distances with fewer supports. Due to the greater diameter of the ACSR conductor, a much higher corona limit can be obtained which is advantageous on high and extra high voltage overhead lines.
Aluminium Conductors, Steel-Reinforced (ACSR) can be supplied to meet various International Standards as follows:
- IS 398 Part 2
- BS 215 / 2
- IEC 61089
- DIN 48204
- ASTM B 232
However, We can also supply a range of alternative designs to meet customer-specified requirements.
