Clevis and tongue couplings of string insulator units - Dimensions

IEC 60471:2020 applies to string insulator units of the cap and pin type and also of the long rod type as well as the fittings used with such insulators. The object of this document is to define the dimensions of a series of clevis and tongue couplings to permit the assembly of insulators or fittings supplied by different manufacturers. This third edition cancels and replaces the second edition published in 1977. This edition includes the following significant technical changes with respect to the previous edition: - there are no new clevis and tongue couplings; - For the dimensions of the existing designated size of couplings that characterize the same location, the effective number of the size is unified.

Assemblages à chape et tenon des éléments de chaînes d'isolateurs - Dimensions

IEC 60471:2020 s’applique aux éléments de chaînes d’isolateurs de type à capot, à tige et également à long fût ainsi qu’aux accessoires métalliques qui leur sont associés. L’objet du présent document est de définir les dimensions d’une série d’assemblages à chape et tenon afin de permettre l’assemblage d’isolateurs ou d’accessoires métalliques fournis par différents fabricants. Cette troisième édition annule et remplace la deuxième édition parue en 1977. La présente édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: - Selon les résultats du questionnaire (36/424/Q), il est confirmé qu’il n’existe pas de nouveaux assemblages à chape et tenon; - Concernant les dimensions de tailles d’assemblage normalisées existantes qui caractérisent le même emplacement, le nombre de la taille en vigueur est unifié.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a 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 other 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 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 conditions 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 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 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 Publication 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 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 technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or in

19 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

20 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

21 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

22 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

23 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

24 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

25 in the subject dealt with may participate in this preparatory work. International, governmental and non-

26 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

27 with the International Organization for Standardization (ISO) in accordance with conditions determined by

28 agreement between the two organizations.

29 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

30 consensus of opinion on the relevant subjects since each technical committee has representation from all

31 interested IEC National Committees.

32 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

33 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

34 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

35 misinterpretation by any end user.

36 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

37 transparently to the maximum extent possible in their national and regional publications. Any divergence

38 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

39 the latter.

40 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

41 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

42 services carried out by independent certification bodies.

43 6) All users should ensure that they have the latest edition of this publication.

44 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

45 members of its technical committees and IEC National Committees for any personal injury, property damage or

46 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

47 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

48 Publications.

49 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

50 indispensable for the correct application of this publication.

51 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

52 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

53 International Standard IEC 60471 has been prepared by IEC technical committee 36: Insulator.

54 This 3rd edition cancels and replaces the 2nd edition published in 1977. This edition

55 constitutes a technical revision.

56 This edition includes the following significant technical changes with respect to the previous

57 edition:

58 a) According to the results of the questionnaire(36/424/Q), it is confirmed that there is no

59 new clevis and tongue couplings;

60 b) For the dimensions of the existing designated size of couplings that characterize the same

61 location, the effective number of the size is unified.
62 The text of this International Standard is based on the following documents:
