IEC 60317-71 pdf – Specifications for particular types of winding wires – Part 71: Polyester glass-fibre wound and resin or varnish impregnated, bare or enamelled round copper wire, temperature index 180
1 Scope
This part of lEC 60317 specifies the requirements of polyester glass-fibre wound resin/varnish
impregnated,bare，grade 1 or grade 2 enamelled round copper winding wire,temperatureindex 180.
NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot beestablished. Consequently，a class based on the requirements for temperature index and heat shock temperaturecannot be specified.
The nominal conductor diameters are specified in IEC 60317-O-10:2017,Clause 4.

3.2.1Methods of test
Subclause 3.2.1 of IEC 60317-0-10:2017applies. In case of inconsistencies betweenIEC 60317-0-10 and this document, the latter shall prevail.
3.2.2Winding wire
The fibre covering shall consist of a combination of polyester and glass fibres. The glassfibres shall be electrical-grade continuous-filament glass yarn. The polyester fibre shall be ahigh-grade yarn resulting from the linear polymerization of ethylene glycol and terephthalicacid.The maximum content by weight of polyester fibre in the yarn shall not exceed 50 %.
The enamelled wire shall have a temperature index of at least 180 and shall be agreed between purchaser and supplier.
The temperature index of the wire is dependent upon the type of impregnating agent used.
The impregnating agent applied to the polyester glass fibre shall have a minimum temperature index of 180.
The covering shall have one of the following grades of thickness:
– PG1: bare conductor with 1 layer of polyester glass fibre or 2 layers of finer polyester glass fibres that together, comply with the dimensional requirements in IEC 60317-0-10;
– PG2: bare conductor with 2 layers of polyester glass fibre;
– grade 1 PG1: enamelled grade 1 (grade 1) with 1 layer of polyester glass fibre (PG1);
– grade 1 PG2: enamelled grade 1 (grade 1) with 2 layers of polyester glass fibre (PG2);
– grade 2 PG1: enamelled grade 2 (grade 2) with 1 layer of polyester glass fibre (PG1);
– grade 2 PG2: enamelled grade 2 (grade 2) with 2 layers of polyester glass fibre (PG2).
