IEC 60317-71:2020 pdf free download 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 (IEC 60317-71:2020)
scope
This part of lEC 60317 specifies the requirements of polyester glass-fibre wound resinlvarnishimpregnated, 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 lEC 60317-0-10:2017,Clause 4.

3.2.1 Methods of test
Subclause 3.2.1 of IEC 60317-0-10:2017 applies. ln case of inconsistencies betweenlEC 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 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 6031 7-0-1 0;
– 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).
