AACSR Aluminium Wires | Aluminium Conductors - STEP INDUSTRIES

All Alloy Aluminum Conductor Steel Reinforced/ Aluminium Wires (AACSR/ AW)

The AACSR conductors are also suitable for use in all practical transmission towers, and other structures. Application ranges from extra high voltage (EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises as like as ACSR.


AACSR (Aluminum Alloy Conductor Steel Reinforced) has also a long service record because of its economy, dependability, and strength to weight ratio. The combined light weight and high conductivity of aluminum with strength of the steel cores enable higher tensions, less sag, and longer spans than any alternative as like as ACSR.

Compared with ACSR, the tensile strength of aluminum conductor is stronger.

  1. offers optimal strength for line design.
  2. improved strength to weight ratio
  3. ideal for extra-long span with heavy load
  4. excellent resistance to corrosion.

AACSR/AW - Aluminum Alloy Conductor, Steel Reinforced*


Used as bare overhead transmission cable and as primary and secondary distribution cable. AACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing Ampacity.


JSK's bare AACSR conductor can meet any International Standard including ASTM, BS, DIN, IEC, NFC etc


AACSR is a concentrically stranded conductor composed of one or more layers of 6201 -T81 aluminum alloy wire stranded with a high-strength coated steel core. The core may be single wire or stranded depending on the size.

The proportions of aluminum alloy and steel can be varied to obtain the relation between current carrying capacity and mechanical strength best suited to each application.

Core wire for AACSR is available with Class A, B or C-galvanized; "aluminized" (AZ): or aluminum clad (AW).

Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
