This document specifies the properties of wires in the diameter range of, but not limited to, 1,25 mm to 5,50 mm. This standard is applicable to coated or cladded metallic wires before stranding used either as concentric lay overhead stranded conductors, or in the manufacture of cores for concentric lay overhead stranded conductors, for power transmission purposes. The various wire types and their designations are listed in Table A.1. For calculation purposes the values listed in Table B.1 shall be used.
