This part of IEC 60317 specifies the requirements of polyester glass-fibre wound, resin or varnish impregnated bare, grade 1 or grade 2 enamelled rectangular copper winding wires,temperature index 180. The impregnating agent can be, for instance, epoxy, polyester, or polyesterimide resin based.
NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified.
The range of nominal conductor dimensions covered by this document is:
– width:  min. 2,0 mm  max. 16,0 mm;
– thickness: min. 0,80 mm  max. 5,60 mm.
The specified combinations of width and thickness as well as the specified width/thickness ratio are according to IEC 60317-0-8.dition 2.0 2020-05 INTERNATIONAL STANDARD NORME INTERNATIONALE Specifications for particular types of winding wires – Part 61: Polyester glass-fibre wound, resin or varnish impregnated, bare or enamelled rectangular copper wire, temperature index 180 Spécifications pour types particuliers de fils de bobinage – Partie 61: Fil de section rectangulaire en cuivre nu ou émaillé, guipé de fibres de verre polyester imprégnées de résine ou de vernis, d'indice de température 180 I
