IEC 60317-62:2020 pdf free download 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
1 Scope
This part of IEC 6031 7 specifies the requirements of polyester glass-fibre wound, silicone resin or varnish impregnated bare, grade 1 or grade 2 enamelled rectangular copper winding wires, temperature index 200. The impregnating agent is a silicone containing resin or varnish.
The range of nominal conductor dimensions covered by this document is:
– width: min. 2,0 mm max. 1 6,0 mm;
– thickness: min. 0,80 mm max. 5,60 mm.
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.

3.2 General notes
3.2.1 Methods of test
Subclause 3.2.1 of IEC 6031 7-0-8:201 2201 9 applies. In case of inconsistencies between IEC 6031 7-0-8 and this document, the latter shall prevail.
3.2.2 Winding wire
The fibre covering shall consist of a combination of polyester and glass fibres. The glass fibres shall be electrical-grade continuous-filament glass yarn. The polyester fibre shall be a high-grade yarn resulting from the linear polymerization of ethylene glycol and terephthalic acid. 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 agreed between purchaser and supplier.
– 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 7-0-8;
– 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/thickness ratio are in accordance with IEC 6031 7-0-8.
