EN IEC 60471:2020

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
