The series has three groups describing:
25、1) Winding wires Test methods (IEC 60851); 2) Specifications for particular types of winding wires (IEC 60317); 3) Packaging of winding wires (IEC 60264).

26、apped rectangular copper wire, temperature index 220 1 Scope This part of IEC 60317 specifies requirements for tape wrapped rectangular copper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses. NOTE The
27、heat shock test is inappropriate for this type of wire, 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 standa
28、rd is: width: min. 2,00 mm max. 16,00 mm; thickness: min. 0,80 mm max. 5,60 mm. The specified combinations of width and thickness as well as the specified ratio width/thick-ness are given in Table 1. 2 Normative references The following documents, in whole or in part, are normatively referenced in t

31、finitions For the purpose of this document, the following terms and definitions apply. 3.1.1 class thermal performance of a wire expressed by the temperature index and the heat shock temperature BS EN 60317-53:2014 8 IEC 60317-53:2014 IEC 2014 3.1.2 conductor bare metal after removal of the insulati
32、on 3.1.3 covering material which is wound, wrapped or braided around a bare or insulated conductor 3.1.4 insulation coating or covering on the conductor with the specific function of withstanding voltage 3.1.5 winding wire wire used for winding a coil to provide a magnetic field 3.1.6 wire conductor
33、 coated or covered with an insulation 3.2 General notes 3.2.1 Methods of test All methods of test used in this part of IEC 60317 are given in IEC 60851. The clause numbers used in this standard are identical to the corresponding test numbers in the IEC 60851 series of standards. In case of inconsist
34、encies between the publication on methods of test and this standard, IEC 60317-53 shall prevail. Where no specific range of nominal conductor dimensions is given for a test, the test applies to all nominal conductor dimensions covered by the specification sheet. Unless otherwise specified, all tests
35、 shall be carried out at a temperature from 15 C to 35 C and a relative humidity from 45 % to 75 %. Before measurements are made, the specimens shall be preconditioned under these atmospheric conditions for a time sufficient to allow the specimens to reach stability. The wire to be tested shall be r
36、emoved from the packaging in such a way that the wire will not be subjected to tension or unnecessary bends. Before each test, sufficient wire should be discarded to ensure that any damaged wire is not included in the test specimens. 3.2.2 Winding wire One or more tape layers may be applied. Combina
37、tions of different types, different thickness and degree of overlap shall be agreed between the purchaser and the supplier. Where adhesive is used to secure the loose ends of the tape, it shall be compatible with the insulation system in use. The temperature in degrees Celsius corresponding to the t
38、emperature index is not necessarily that at which the wire is recommended to be operated and this will depend on many factors, including the types of equipment involved. BS EN 60317-53:2014IEC 60317-53:2014 IEC 2014 9 When reference is made to winding wire according to this standard, the following i
39、nformation should be given: reference to IEC 60317-53; dimensions of the conductor; reference should also be made to the number and thickness of the papers used and to the degree of overlap, as agreed between purchaser and supplier. 3.3 Appearance Before wrapping, the conductor shall be completely f
40、ree from copper dust and other extraneous matter. The tape covering shall be essentially smooth and continuous, wrapped around the conductor tightly, evenly and free from creases, wrinkles and foreign material when examined with normal vision, as wound on the original spool or reel. 4 Dimensions 4.1
41、 Conductor dimensions The dimensions for widths and thicknesses of conductors of winding wires with rectangular cross-section recommended in this standard are taken from the R 20 and R 40 series according to ISO 3. Preferred sizes are combinations of width and thickness both according to the R 20 se
42、ries. Intermediate sizes are combinations of width or thickness according to the R 20 series with the other dimension according to the R 40 series. This standard covers: widths from 2,00 mm up to and including 16,00 mm; thicknesses from 0,80 mm up to and including 5,60 mm.*The ratio width/thickness
43、shall be greater than or equal to 1,4:1 and shall not exceed 8:1. The actual values of dimensions are given in Table 1.*The nominal cross-sectional areas for preferred sizes are given in Table 1. _ *For thicknesses over 5,60 mm up to and including 10 mm and for widths over 16 mm up to and including
44、25 mm where, for technical reasons, additional sizes may be needed, the R 40 series shall be used. The ratio width/thickness shall be within the specified limits and combinations of R 40 and R 40 are not allowed in the case of additional sizes. *Dimensions according to R 20 series are printed in lar
45、ger type.

If there is no agreement, the minimum increase in width or thickness due to the tape covering shall not be less than the values calculated using the following formula: 2 Tmin.iniwhere Tmin.iis the minimum thickness of the paper in the layer number i and niis determined by the degree of overlap in th
