IEC 60317-0-6:2020 specifies the general requirements of glass-fibre wound resin or varnish impregnated, bare or enamelled, round copper winding wires. The range of nominal conductor diameters is given in the relevant specification sheet. This second edition cancels and replaces the first edition published in 2001 and Amendment 1:2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- revision to 3.3, Appearance;
- revision to Table 1, maximum overall diameter of grade 1 wire over single-glass fibre covering for nominal conductor diameters 1,600 mm - 5,000 mm;
- revision to Table 2, maximum overall diameter of grade 1 wire over double-glass fibre covering for nominal conductor diameters 1,600 mm - 5,000 mm;
clarification in Table 3 measurement of elongation as “minimum elongation %”.
