28、24 IEC:2013 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ RAILWAY APPLICATIONS FIXED INSTALLATIONS ELECTRIC TRACTION INSULATING SYNTHETIC ROPE ASSEMBLIES FOR SUPPORT OF OVERHEAD CONTACT LINES FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizatio
29、n 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 activities, IEC publishes Internationa
30、l 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 subject dealt with may participate in thi
31、s 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 determined by agreement between the two
32、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 Committees. 3) IEC Publications have the
33、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 which they are used or for any misinterpr
34、etation 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 Publication and the corresponding national or
35、 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 not responsible for any services carried
36、 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 technical committees and IEC National Commit
37、tees 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 Publications. 8) Attention is drawn to
38、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 subject of patent rights. IEC shall not be he
39、ld responsible for identifying any or all such patent rights. International Standard IEC 62724 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is derived from EN 50345. The text of this standard is based on the following documents: FDIS Re
40、port on voting 9/1853/FDIS 9/1870/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. 62724 IEC:2013 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided th
41、at 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 a revised edition, or amended. IMP
42、ORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 62724 IEC:2013 INTRODUCTION This International
43、standard has been prepared to provide general guidance and to define special requirements for the design and testing of insulating synthetic ropes, their sheaths and their terminations for use in electric traction overhead contact lines. Special preferences will include such requirements as to compl
44、y with local procurement policies, working practices, compatibility with existing systems, to combat environmental pollution and to provide a supporting assembly with insulation which will give reliable service over its target life span. These insulating synthetic ropes offer an alternative to the u
45、se of metallic cables associated with conventional insulators. 62724 IEC:2013 7 RAILWAY APPLICATIONS FIXED INSTALLATIONS ELECTRIC TRACTION INSULATING SYNTHETIC ROPE ASSEMBLIES FOR SUPPORT OF OVERHEAD CONTACT LINES 1 Scope This International standard applies to the insulating synthetic ropes used in
46、overhead contact lines. This International standard specifies the requirements of insulating synthetic rope assemblies and is applicable to electric traction overhead contact lines for railways, light railways, tramways, trolleybuses and other systems. These insulating synthetic ropes are utilised t
47、o provide mechanical support and electrical insulation for overhead contact lines. They are generally used in the following application fields: delta suspension of contact wires; catenary cable; mid-point anchors; tie; dropper; headspan; noise and vibration damper; bridle- and pulley suspensions; ca
48、ntilevers made of glass reinforced polymer (GRP). This standard establishes requirements and characteristics of the rope, test methods and checking procedures to be used with the insulating synthetic ropes, together with the ordering and delivery requirements. The synthetic ropes only for mechanical
49、 applications are not part of this international standard. Anyway the mechanical requirements and tests stated in this standard can be used for this kind of ropes. The object of this standard is to stipulate provisions for the design and to allow provision of the service indicated by the supplier to the purchaser or informed buyer. 2 Normative references The following documents, in whole or
