Lapwing/ACSS/AW

STANDARDS

ACSS/AW conductor meets or exceeds the following ASTM standards:                                      

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.

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.
