23、 worldwide 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 ot
24、her 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
25、 subject 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 condition
26、s determined 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
27、 Committees. 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
28、 which 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 Pub
29、lication 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 i
30、s not 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 te
31、chnical 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 I
32、EC 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 sub
33、ject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62231-1 has been prepared by IEC technical committee 36: Insulators. The text of this standard is based on the following documents: FDIS Report on voting 36/372/FDIS 36/
34、373/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.

The committee has decided that the contents of this publication will remain unchanged until the stability date i
36、ndicated 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. BS EN 62231-1:2016IEC 62231-1:2015 IEC 2015 5 COMPOSITE STATION POST INSULATORS FOR SUB
37、STATIONS WITH AC VOLTAGES GREATER THAN 1 000 V UP TO 245 kV Part 1: Dimensional, mechanical and electrical characteristics 1 Scope This part of IEC 62231 is applicable to composite station post insulators for substations with a.c. voltages greater than 1 000 V up to 245 kV. It also applies to compos
38、ite station post insulators of similar design used in power stations of railway systems. This part of IEC 62231 specifies main dimensions and values for mechanical and electrical characteristics of composite station post insulators. NOTE The composite station post insulators covered by this standard
39、 are primarily intended for outdoor service, but can also be used indoor. 2 Normative references The following documents, 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 refe
