Aluminum Alloy Conductor Steel Reinforced (AACSR) Cable – High Strength Overhead Conductor – IEC, ASTM, DIN, NF

Overhead Line
Description

Product Overview

The AACSR with high strength are used in river crossing conductors, transmission of power through overhead ground wires on long span installations against any given resistance of conductor. It can be used as large span conductor, heavy ice wire or overhead communications wire, ground wire. Temperature for continuous use can be up to 90 °C. Temperature of heat‑resistant AACSR can be up to 150 °C and above. It has high current carrying capacity.

Standards: ASTM, AS, BS, CSA, DIN, IEC, NFC, SS – etc.

Conductor Type Aluminum Alloy Conductor Steel Reinforced (AACSR)
Operating Temperature (standard) Up to 90°C
Operating Temperature (heat‑resistant) Up to 150°C and above
Applications River crossing, long span, heavy ice, ground wire

Construction

  1. Steel part: Zinc‑coated steel wires, one or multi‑wires concentric stranded. Core wire available with Class A, B or C galvanized; “aluminized” (AZ); or aluminum clad (AW). Additional corrosion protection via grease to core or complete cable infusion.

  2. Aluminium alloy part: Aluminium alloy wires (6201‑T81), concentric stranded.

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.
