AACSR Aluminum Alloy Conductor Steel Reinforced
AACSR, also known as steel cored aluminum alloy stranded wire, is a concentric twisted composite conductor used for overhead transmission lines. The outer layer is made of aluminum magnesium silicon alloy (6201-T81), and the inner layer is made of high-strength galvanized/aluminum clad steel core, which combines high conductivity, high strength, and low sag characteristics.

Application
AACSR is used for high voltage/ultra-high voltage transmission; Heavy ice/strong wind areas; Coastal/corrosive environment; Overhead communication/ground wire
Applicable Standards
International: IEC 61089
United States: ASTM B711 (latest B711-22)
China: GB/T 1179
Common Specifications
Section: 16-1000 mm ²
Structure: such as 45/3.83+7/2.55 (45 aluminum alloy wires+7 steel wires)
Steel ratio: about 15% -25% (by section)
Construction
- Steel core: single or multiple stranded, made of galvanized steel (A/B/C grade), aluminum clad steel (AW) or Zn-5Al rare earth alloy coated steel, providing high tensile strength.
- Aluminum alloy layer: The outer layer is 6201-T81 aluminum magnesium silicon alloy wire (solution heat treatment+cold processing+artificial aging), with a conductivity of about 61% IACS and higher strength than pure aluminum.
- Twisting method: concentric layer twisting, steel core centered, aluminum alloy wire twisted layer by layer; Can be coated with anti-corrosion grease to enhance corrosion resistance.
- *We can design and produce according to client's requirement.
