Alcan's ACSR/TW cable is a concentric lay-stranded conductor consisting of a stranded steel central core with one or more layers of trapezoidal shaped 1350 aluminum wires.  Steel core wires are protected from corrosion by galvanizing, aluminizing, aluminum-clad alloy or zince - 5% aluminum misch metal alloy coating.  Standard, Extra, High and Ultra High strength steel are also available in a non-specular finish.

Alcan's ACSR/TW cable meets or exceeds industry requirements per ASTM specification B779.

Alcan's ACSR/TW bare conductors are available in two designs.  The first design is an ACSR/TW conductor having the same area as the standard ACSR round wire conductor.  This gives a conductor with a smaller overall conductor diameter and results in lower wind and ice loads, while maintaining the same ampacity.  The second design is an ACSR/TW bare conductor with an overall diameter equal to the standard ACSR conductor.  This design provides up to a 20% increase in aluminum area which results in higher current carrying capacity.
