ACSS/AW Conductor

ACSS/AW
-------------- BARE OVERHEAD ALUMINUM CONDUCTOR ALUMINUMCLAD STEEL-SUPPORTED, CONCENTRIC-LAY-STRANDED

1. GENERALITIES:
ACSS/AW is a composite concentric-lay-stranded cable. Aluminum-clad steel strands form the central core of the cable around which is stranded one or more layers of aluminum 1350-O wires. ACSS/AW conductors are manufactured in accordance with the latest applicable issue of ASTM B856.

The "O" temper of the aluminum, a fully annealed or soft temper, causes most or all of the mechanical load of ACSS/AW to be carried by the steel. The Aluminum-Clad steel core may consist of 7, 19, 37 or more wires. Numerous combinations of aluminum and steel strand and layers are possible.

The sizes and strandings listed on the following pages are those most frequently used for overhead lines.

2. FEATURES AND BENEFITS:
The AW core, which consists of a thick layer of aluminum (approx. 10% of the nominal wire \ radius) over steel, gives ACSS/AW conductors the advantages of standard ACSS along with light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. The crosssections above illustrate some common stranding.

3. APPLICATIONS:
Aluminum Conductor, Steel-Supported with aluminum-clad steel wire (ACSS/AW) are used for overhead distribution and transmission lines where a high degree of corrosion resistance is required.

4. OPTIONS:
High-Strength aluminum-clad steel core (/HSAW).
Extra-High-Strength aluminum-clad steel core (/EHSAW).
Ultra-High-Strength aluminum-clad steel core (/UHSAW).
Trapezoidal-shaped aluminum strands (/TW).
