IEC 60317-62 pdf – Specifications for particular types of winding wires – Part 62: Polyester glass-fibre wound, silicone resin or varnish impregnated, bare or enamelled rectangular copper wire, temperature index 200
This part of IEC 60317 specifies the requirements of polyester glass-fibre wound,siliconeresin or vamish impregnated bare，grade 1 or grade 2 enamelled rectangular copper windingwires,temperatureindex 200. The impregnating agent is a silicone containing resin orvarnish.
The range of nominal conductor dimensions covered by this document is:- width:min. 2,0mm max.16,0mm;
– thickness: min. 0,80mmmax.5,60mm.
NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot beestablished. Consequenly，a class based on the requirements for temperature index and heat shock temperaturecannot be specified.
The following documents are referred to in the text in such a way that some or all of theircontent constitutes requirements of this document. For dated references，only the editioncited applies. For undated references, the latest edition of the referenced document (inciuding
any amendments) applies.

3.2.1 Methods of test
Subclause 3.2.1 of IEC 60317-0-8:2019applies. In case ofinconsistencies betweenIEC60317-0-8 and this document, the latter shall prevail.
The fibre covering shall consist of a combination of polyester and glass fibres. The glassfibres shall be electrical-grade continuous-flament glass yarn. The polyester fibre shall be ahigh-grade yam 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 200 and shall be agreedbetween purchaser and supplier.
The temperature index of the wire is dependent upon the type of impregnating agent used.The silicone-containing impregnating agent applied to the polyester glass fibres shall have aminimum temperature index of 200.
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 60317-0-8;
– 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)
The specified combinations of width and thickness as well as the specified width/thicknessratio are in accordance with lEC 60317-0-8.
Subclause 3.3 of IEC 60317-0-8:2019 applies.
Clause 4 of lEC 60317-0-8:2019 applies.
5 Electrical resistance
Clause 5 of lEC 60317-O-8:2019 applies.
