26、014 INTRODUCTION This part of IEC 60317 is one of a series which deals with insulated wires used for windings in electrical equipment. The series has three groups describing: 1) Winding wires Test methods (IEC 60851); 2) Specifications for particular types of winding wires (IEC 60317); 3) Packaging
27、of winding wires (IEC 60264). BS EN 60317-52:2014IEC 60317-52:2014 IEC 2014 7 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 52: Aromatic polyamide (aramid) tape wrapped round copper wire, temperature index 220 1 Scope This part of IEC 60317 specifies requirements for tape wrapped round c
28、opper winding wire of temperature index 220. The insulation consists of one or more wrappings of aromatic polyamide (aramid) tape of various thicknesses. NOTE The heat shock test is inappropriate for this type of wire. Therefore a heat shock temperature cannot be established. Consequently, a class b
29、ased on the requirements for temperature index and heat shock temperature cannot be specified. The range of nominal conductor diameters covered by this standard is: 1,600 mm up to and including 5,000 mm; the nominal conductor diameters are given in Table 1. 2 Normative references The following docum
30、ents, 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 60172, Test procedure

32、3, Preferred numbers Series of preferred numbers 3 Terms, definitions, general notes and appearance 3.1 Terms and definitions For the purposes 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
33、temperature 3.1.2 conductor bare metal after removal of the insulation BS EN 60317-52:2014 8 IEC 60317-52:2014 IEC 2014 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
34、withstanding voltage 3.1.5 winding wire wire used for winding a coil to provide a magnetic field 3.1.6 wire conductor 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 thi
35、s standard are identical to the corresponding test numbers in the IEC 60851 series of standards. In case of inconsistencies between the publication on methods of test and this standard, IEC 60317-52 shall prevail. Where no specific range of nominal conductor diameters is given for a test, the test a
36、pplies to all nominal conductor diameters covered by the specification sheet. Unless otherwise specified, all tests 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 atmos
37、pheric conditions for a time sufficient to allow the specimens to reach stability. The wire to be tested shall be removed 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 dam
38、aged wire is not included in the test specimens. 3.2.2 Winding wire The temperature in degrees Celsius corresponding to the temperature 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. When
39、reference is made to winding wire according to this standard, the following information should be given: reference to IEC 60317-52; diameter of the conductor; reference should also be made to the number and thickness of the tapes used and to the degree of overlap, as agreed between the purchaser and
40、 supplier. 3.3 Appearance Before wrapping, the conductor shall be completely free from copper dust and other extraneous matter. BS EN 60317-52:2014IEC 60317-52:2014 IEC 2014 9 The tape covering shall be essentially smooth and continuous, wrapped around the conductor tightly, evenly and free from cre
41、ases, wrinkles and foreign material when examined with normal vision, as wound on the original spool or reel. 4 Dimensions 4.1 Conductor diameter The series of preferred nominal conductor diameters shall correspond to series R20 according to ISO 3. The actual values and their tolerances are given in
42、 Table 1. The series of intermediate diameters from which the user may select intermediate nominal conductor diameters, when required for technical reasons, shall correspond to series R40 according to ISO 3. The actual values and their tolerances are given in Annex A. The conductor diameter shall no
43、t differ from the nominal diameter by more than the limits given in Table 1. Table 1 Conductor diameters Nominal conductor diameter Tolerance Nominal conductor diameter Tolerance mm mm mm mm 1,600 0,016 3,150 0,032 1,800 0,018 3,550 0,036 2,000 0,020 4,000 0,040 2,240 0,022 4,500 0,045 2,500 0,025 5
44、,000 0,050 2,800 0,028 NOTE The dimensions of intermediate nominal conductor diameters for R40 series are given in Annex A. 4.2 Out of roundness of conductor The difference between the minimum and maximum diameter, at any one point, shall not be more than the figure given in columns 2 and 4 of Table
45、 1. 4.3 Minimum increase in diameter due to insulation The minimum increase in diameter due to the insulation shall not be less than the values calculated using the following formula: 2 Tmin.iniwhere Tmin.i is the minimum thickness of the tape in layer number i and niis determined by the degree of o
46、verlap in that layer: for overlaps of 0 % up to, but not including 50 % n = 1; for overlaps of 50 % up to, but not including 66 % n = 2; for overlaps of 66 % up to, and including 75 % n = 3. Minimum thickness shall be calculated from the values given in Table 1 of IEC 60819-3-3:2011 where the permis
47、sible deviation of the central thickness value is: BS EN 60317-52:2014 10 IEC 60317-52:2014 IEC 2014 for nominal thickness 0,05 mm 20 % for nominal thicknesses 0,08 mm and greater 15 %. EXAMPLE 1 For a construction using two layers of 0,05 mm tape with 50 % overlap: Tmin.1 = 0,04 mm, n1= 2 Tmin.2= 0
48、,04 mm, n2= 2 Therefore, the minimum increase due to the insulation equals: 2 (0,04 2 + 0,04 2) mm = 0,320 mm EXAMPLE 2 For a construction using one layer of 0,05 mm tape with an overlap of 55 % followed by two layers of 0,08 mm tape with no overlap: Tmin.1= 0,04 mm, n1= 2 Tmin.2= 0,068 mm, n2= 1 Tm
49、in.3= 0,068 mm, n3= 1 Therefore, the minimum increase due to the insulation equals: 2 (0,04 2 + 0,068 1 + 0,068 1) mm = 0,432 mm As there are many varied constructions of this type of wire, the dimensions due to the insulation are subject to agreement between purchaser and supplier and shall be clearly stated in the purchase order. 4.4 Maximum overall diameter The overall diameter shall not exceed the sum of the maximum conductor diameter given in T
