Aluminium Alloy Conductor Steel Reinforced Conductors (AACSR) is a concentrically stranded conductor composed of one or more layers of 6201-T81 Aluminium Alloy (Aluminium-Magnesium-Silicon) wire stranded with a high-strength coated steel core. The core may be single wire or stranded depending on the size.The proportions of aluminium 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 aluminium clad (AW) coating to provide protection from corrosion.Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
AACSR Conductors have approx. 40% to 60% more strength than comparable standard ACSR with only 8 to 10% decrease in conductivity.
Aluminium Conductors, Aluminium-Clad Steel Reinforced (ACSR/AW) is designed and tested to meet or exceed the following specifications:
- BS EN 50182
- ASTM B-711
- IEC 61089
