Aluminium Conductors, Aluminium Clad Steel Reinforced (ACSR/AS or ACSR/AW) are concentrically stranded conductors with one or more layers of hard drawn 1350-H14 aluminium wires on Aluminium Clad steel wire core. The core can be single wire or stranded depending on the size.

The mechanical properties of ACSR/AS conductors are similar to ACSR conductors but offers improved ampacity and resistance to corrosion because of the presence of aluminium clad steel wires in the core. These conductors are better replacement for ACSR conductors where corrosive conditions are severe.


  • good mechanical properties
  • improved electrical characteristics
  • excellent corrosion resistance
  • better Sag properties


ACSR/AS manufactured by SIM ROD SAMA meets or exceeds the requirements of all international standards like ASTM, AS, BS, CSA, DIN, IEC, NFC, SS -etc .

Complete Conductor

AW is a composite concentric lay stranded conductor. ACSR/AW conductors are manufactured in  ccordance stranded c onductor of 7,19,37 or more wires. Numerous combinations of aluminum and steel strands and layers are possible. The sizes and stranding listed on the following pages are those most frequently used for overhead lines with the requirements of the latest appl icable ASTM specification B549 issues. Aluminum clad steel strands form the central core of the conductor, around which is stranded one or more layers of aluminum 1350 H1 4 wires. The aluminum clad steel core may consist of a single strand or a concentric.


The AW core, which consists of a thick layer of aluminum (approx. 10 percent of the nominal wire radius) over steel, gives ACSR/AW conductors the advantage of the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. The cross sections above illustrate some common standings.


Aluminum conductors reinforced with aluminum clad steel wire (ACSR/AW) are used for overhead distribution and transmission lines where a high degree of corrosion resistance is needed. It should also be considered for use in locations where air pollution exists, such as along the coast or in highly industrialized are as.
SIM ROD SAMA can manufacture and supply ACSR/AS on wooden / steel reels depending on customer requirement.
