Insulators for overhead lines with a nominal voltage above 1000 V - Ceramic insulators for AC systems - Characteristics of insulator units of the long rod type

IEC 60433:2021 is applicable to string insulator units of the long rod type with insulating parts of ceramic material intended for use in AC overhead power lines with a nominal voltage greater than 1000 V and a frequency not greater than 100 Hz. It is also applicable to insulators of similar design, used in substations. This document is applicable to ceramic string insulator units of the long rod type, either with a clevis end fitting at both ends for coupling with a tongue, or with a socket end fitting at both ends for coupling with a pin ball. The object of this document is to prescribe specified values for electrical and mechanical characteristics, and for the principal dimensions of ceramic string insulator units of the long rod type. This fourth edition cancels and replaces the third edition published in 1998. This edition includes the following significant technical changes with respect to the previous edition: - wording in Scope changed from "should" to "are intended to"; - new normative references added; - title of Clause 4 amended, new Note 4 added; - Table 1 expanded to include more specified mechanical failing loads.

Isolateurs pour lignes aériennes de tension nominale supérieure à 1 000 V - Isolateurs en céramique pour réseaux à tension alternative - caractéristiques d'isolateurs du type à long fût

L'IEC 60433:2021 s'applique aux éléments de chaînes d'isolateurs du type à long fût ayant des parties isolantes en matière céramique destinés aux lignes aériennes fonctionnant en courant alternatif à une tension nominale supérieure à 1 000 V et à une fréquence au plus égale à 100 Hz. Elle s'applique également aux isolateurs du même type utilisés dans les postes. Le présent document s'applique aux éléments de chaînes d’isolateurs en céramique du type à long fût ayant à chaque extrémité soit une chape destinée à recevoir un tenon, soit un logement de rotule pour assemblage avec une tige à rotule. Le présent document a pour objet de prescrire des valeurs spécifiées pour les caractéristiques électriques et mécaniques et pour les principales dimensions des éléments de chaînes d'isolateurs en céramique du type à long fût. Cette quatrième édition annule et remplace la troisième édition parue en 1998. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - reformulation du domaine d'application: "il convient d’utiliser les caractéristiques mécaniques ainsi que les longueurs L (voir Article 4) de la présente norme " remplacé par "les caractéristiques mécaniques ainsi que les longueurs L (voir Article 4) de la présente norme sont prévues pour être utilisées"; - ajout de nouvelles références normatives; - modification du titre de l'Article 4, ajout d'une nouvelle Note 4; - Le Tableau 1 a été étoffé pour intégrer un plus grand nombre de charges de rupture mécanique spécifiées.

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 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 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 held responsible for identifying any or all such patent rights.

International Standard IEC 60433 has been prepared by IEC technical committee 36:

Insulators.
