IEC 60317-62:2020 pdf download.Specifications for particular types of winding wires – Part 62: Polyester glass-fibre wound
1 Scope
This part of IEC 60317 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 mm max. 16,0 mm; mm. – thickness: min. 0,80 max. 5,60 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 Terms, definitions, general notes and appearance
3.1 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60317-0-8 apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • • IEC Electropedia: available at http://www.electropedia.org/ ISO Online browsing platform: available at http://www.iso.org/obp. 3.2 General notes 3.2.1 Methods of test Subclause 3.2.1 of IEC 60317-0-8:2019 applies. In case of inconsistencies between IEC 60317-0-8 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. 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 a minimum 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/thickness ratio are in accordance with IEC 60317-0-8. 3.3 Appearance Subclause 3.3 of IEC 60317-0-8:2019 applies.
