ACSS/AW is a composite concentric-lay-stranded conductor. Aluminum-clad steel strands, either AW2 (normal strength) or AW3 (high strength), form the central core of the conductor with one or more layers of aluminum 1350-0 wire stranded around it. The aluminum-clad steel core carries most or all of the mechanical load of the conductor due to the "0" (fully annealed or soft) temper aluminum. The steel core wires are protected from corrosion by an aluminum coating.
