17、inc-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 a

18、re 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. 2. Values for zinc-coated steel wires For calculation purposes the following

19、 values for zinc-coated steel wires shall be used: Density at 20 of both Class 1 and Class 2 7.78 kg/dm3Coefficient of linear expansion 11.510 6per 3. Material The steel wires shall have the properties specified hereinafter. The slab zinc shall be of 99.85 % minimum zinc content. The coating on the

20、wires may be applied by the hot dip or the electrolytic process. 4. Freedom from defects The uncoated wires shall be smooth and free from all imperfections not consistent with good commercial practice. The zinc-coated wires shall be reasonably smooth and free from all imperfections not consistent wi

21、th good commercial practice. 5. Diameter and tolerance on diameter The diameter of the zinc-coated steel wire shall be taken as the mean of two measurements taken at 90 at the same cross-section. The zinc-coated steel wires shall not depart from the nominal diameter, when measured over the coating,

22、by more than the amounts given in Tables III, IV and V. It is recognized that the surface of zinc-coatings, particularly those produced by hot dip galvanizing, are not perfectly smooth and free from irregularities. It is therefore intended that these tolerances be used in gauging the diameters withi

23、n the uniform areas of zinc-coated wire. 6. Length and tolerance on length Unless otherwise agreed between the purchaser and manufacturer, steel wires shall be supplied with a minimum length specified by the purchaser with a permitted variation of % Random lengths shorter or longer than this requirement are only acceptable if prior agreement between the purchaser and manufacturer is made. 4 0 C IEC 60888： 2006
