IEC 60317-31-2015 pdf Specifications for particular types of winding wires – Part 31: Glass fibre wound, resin or varnish impregnated, bare or enamelled rectangular copper wire, temperature index 180

1 Scope This part of IEC 6031 7 specifies the requirements of glass fibre wound, resin or varnish impregnated, bare or enamelled rectangular copper winding wire, temperature index 1 80. 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. The range of nominal conductor dimensions covered by this standard is: – width: min. 2,0 mm max. 1 6,0 mm; – thickness: min. 0,80 mm max. 5,60 mm. The specified combinations of width and thickness as well as the specified width/thickness ratio are according to IEC 6031 7-0-4. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 6031 7-0-4:201 5, Specifications for particular types of winding wires – Part 0: General requirements – Section 4: Glass fibre wound, resin or varnish impregnated, bare or enamelled rectangular copper wire 3 Terms, definitions, general notes and appearance 3.1 Terms and definitions For the purposes of this document, the terms and definitions given in 3.1 of IEC 6031 7-0- 4:201 5 apply. 3.2 General notes 3.2.1 Methods of test Subclause 3.2 of IEC 6031 7-0-4:201 5 applies. In case of inconsistency between IEC 6031 7-0-4 and this standard, IEC 6031 7-31 shall prevail. 3.2.2 Winding wire The enamelled wire shall have a temperature index of at least 1 80 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 glass fibres shall have a minimum temperature index of 1 80. The covering shall have one of the following grades of thickness: – GL1 : one glass fibre covering over a bare conductor; – GL2: two glass fibre coverings over a bare conductor: – grade 1 GL1 : one glass fibre covering (GL1 ) over grade 1 enamelled conductor (grade 1 ) – grade 1 GL2: two glass fibre coverings (GL2) over grade 1 enamelled conductor (grade 1 ) – grade 2 GL1 : one glass fibre covering (GL1 ) over grade 2 enamelled conductor (grade 2) – grade 2 GL2: two glass fibre coverings (GL2) over grade 2 enamelled conductor (grade 2) 3.3 Appearance Subclause 3.3 of IEC 6031 7-0-4:201 5 applies. 4 Dimensions Clause 4 of IEC 6031 7-0-4:201 5 applies.
