This standard applies to zinc-coated steel wires used in the construction and/or reinforcement of conductors for overhead power transmission purposes.
It is intended to cover all wires used in constructions where the individual wire diameters, including coating, are in the range of 1.25 mm to 5.50 mm.
Three grades of steel are included to reflect the needs of conductor users: regular steel, high strength steel and extra high strength steel.
Two classes of coating represented by minimum zinc mass per unit area are included: Class 1 and Class 2.
