26、CTROTECHNICAL COMMISSION _ SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 70: Polyester glass-fibre wound fused, unvarnished or resin or varnish impregnated, bare or enamelled round copper wire, temperature index 155 FOREWORD 1) The International Electrotechnical Commission (IEC) is a wor

27、ldwide organization for standardization comprising all national electrotechnical committees (IEC 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

28、activities, IEC publishes International Standards, Technical Specifications, Technical Reports, 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 sub

29、ject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions d

30、etermined by agreement between the two organizations. 2) The formal decisions or agreements of IEC 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 Co

31、mmittees. 3) IEC Publications have the form of recommendations for international use and are accepted 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 wh

32、ich they are used or for any misinterpretation by any end user. 4) In order to promote international 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 Public

33、ation and the corresponding national or regional publication shall be clearly indicated in the latter. 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 n

34、ot responsible for any services carried out by independent certification bodies. 6) All users should 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 techn

35、ical committees and IEC National Committees for any personal injury, property damage or other damage 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

36、Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of 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 subjec

37、t of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60317-70 has been prepared by IEC technical committee 55: Winding wires. The text of this standard is based on the following documents: FDIS Report on voting 55/1602/FDIS 5

38、5/1609/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC 60317-70:2017 IEC 2017 A list of all parts in the IEC 60317 series, p

39、ublished 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 packa

40、ging. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by

41、a revised edition, or amended. IEC 60317-70:2017 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 describing: 1) Winding wires Test methods (IEC 60851 serie

42、s); 2) Specifications for particular types of winding wires (IEC 60317 series); 3) Packaging of winding wires (IEC 60264 series). 6 IEC 60317-70:2017 IEC 2017 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 70: Polyester glass-fibre wound fused, unvarnished or resin or varnish impregnated,

43、 bare or enamelled round copper wire, temperature index 155 1 Scope This part of IEC 60317 specifies requirements of polyester glass-fibre wound fused, unvarnished or resin or varnish impregnated, bare or grade 1 or grade 2 enamelled round copper winding wires, temperature index 155. The impregnatin

44、g agent can be, for instance, epoxy, polyester, or polyesterimide resin based. 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 temperatu

45、re cannot be specified. 2 Normative references 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. For dated references, only the edition cited applies. For undated references, the latest edition of the refere

46、nced document (including any amendments) applies.
