15、ON _ SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 68: Polyvinyl acetal enamelled rectangular aluminium wire, class 120 FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC
16、 National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
17、Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- g
18、overnmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of I
19、EC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are acc
20、epted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote internati
21、onal uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the l
22、atter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users sh
23、ould ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other da
24、mage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use o
25、f the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rig
26、hts. International Standard IEC 60317-68 has been prepared by IEC technical committee 55: Winding wires. The text of this standard is based on the following documents: CDV Report on voting 55/1570/CDV 55/1591/RVC Full information on the voting for the approval of this International Standard can be f
27、ound in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. This International Standard is to be read in conjunction with IEC 60317-0-9:2015. 4 IEC 60317-68:2017 IEC 2017 A list of all parts in the IEC 60317, published
28、under the general title Specifications for particular types of winding wires, can be found on the IEC website. The numbering of clauses in this standard is not continuous from Clauses 21 through 30 in order to reserve space for possible future wire requirements prior to those for wire packaging. The
29、 committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition,
30、or amended. A bilingual version of this publication may be issued at a later date. IEC 60317-68:2017 IEC 2017 5 INTRODUCTION This part of IEC 60317 forms an element of a series of standards which deals with insulated wires used for windings in electrical equipment. The series has three groups descri
31、bing: 1) Winding wires Test methods (IEC 60851 series); 2) Specifications for particular types of winding wires (IEC 60317 series); 3) Packaging of winding wires (IEC 60264 series). 6 IEC 60317-68:2017 IEC 2017 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 68: Polyvinyl acetal enamelled
32、rectangular aluminium wire, class 120 1 Scope This part of IEC 60317 specifies the requirements of enamelled rectangular aluminium winding wire of class 120 with a sole coating based on polyvinyl acetal resin, which may be modified providing it retains the chemical identity of the original resin and
33、 meets all specified wire requirements. NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance of application characteristics. The range of nominal conductor dimensions covered by this standard is Minimum Maximum Width
34、2,0 mm 16,0 mm Thickness 0,80 mm 5,60 mm Wires of grade 1 and grade 2 are included in this part of IEC 60317 and apply to the complete range of conductors. The specified combinations of width and thickness as well as the specific ratio width/thickness are given in IEC 60317-0-9. 2 Normative referenc
35、es The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
