Acss Aluminum Conductor Steel Supported Acss/Aw Conductors

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.
 
This catalogue shows the most common sizes of conductor but other sizes, to any recognized standards or customer specification can also be supplied. ACSS/AW insulated with XLPE or PVC can also be supplied as per customer’s requirements.
 
Construction
ACSS/AW is a composite concentric-lay-stranded conductor. Steel strands form the central core of the conductor with one or more layers of aluminum 1350-O wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the "O" (fully annealed or soft) temper aluminum. Steel core wires are protected from corrosion by an aluminum coating. 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.

Specifications
ACSS/AW bare conductor meets or exceeds the following ASTM specifications:
l     B-609 Aluminum 1350 Round Wire, Annealed and Intermediate Tempers, for Electrical Purposes.
l     B-502 Aluminum-Clad Steel Core Wire for Aluminum conductors, Aluminum-Clad Steel Reinforced.
l     B-856 Concentric-Lay-Stranded Aluminum Conductors Coated Steel Supported (ACSS).
The stranding available are identical to those listed in ASTM specification B-232.
