B–803 High–Strength Zinc–5% Aluminum–Mischmetal Alloy-Coated Steel Core Wire for Aluminum and Aluminum–Alloy Conductors, Steel Reinforced.
B–856 Concentric–Lay–Stranded Aluminum Conductors, Coated Steel Supported(ACSS)
CONSTRUCTION
ACSS 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 galvanizing, aluminizing, or mischmetal alloy coating. Corrosion protection should be selected to suit the environment to which the conductor will be exposed. High strength steel core is also available
