Aluminum Conductor Aluminum-Clad Steel-Supported Concentric-Lay-Stranded (ACSS/AW)
Downloding ACSS/AW spicificattion Catalog
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. ACSS/AW offers strength characteristics similar to ACSS, along with slightly greater ampacity and resistance to corrosion due to aluminum-cladding of the steel core wires.
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.
Structure
ACSS/AW is a composite concentriclay-stranded cable. Aluminum-clad steel strands form the central core of the cable around which is stranded one or more layers of aluminum 1350-0 wires. 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.
