This International Standard specifies the general requirements of paper covered rectangular copper winding wires. This covering consists of two or more lappings of paper tape. The range of nominal conductor dimensions covered by this standard is: - width: min. 2,0 mm max. 16,0 mm; - thickness: min. 0,80 mm max. 5,60 mm. When reference is made to a winding wire according to the present standard, the following information is given in the description: - reference to IEC specification; - nominal conductor dimensions in millimetres (width x thickness); - nominal increase in dimensions due to paper. EXAMPLE: IEC 60317-27 - 4,00 x 1,00 0,20
