Insulators for overhead lines with a nominal voltage above 1000 V - Ceramic or glass insulator units for AC systems - Characteristics of insulator units of the cap and pin type

IEC 60305:2021 applies to string insulator units of the cap and pin type with insulating parts of ceramic material or glass, intended for AC overhead lines with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It also applies to insulators of similar design used in substations. This document applies to string insulator units of the cap and pin type either with ball and socket couplings or with clevis and tongue couplings. This document applies to string insulator units for use on overhead lines in clean areas and polluted areas. For use in areas characterized by very heavy pollution levels and for other particular or extreme environmental conditions, it may be necessary for certain dimensions to be changed and insulator units having different creepage distances, spacing and forms may be preferred (for example, flat profile, hemispherical etc.). Insulators for use on DC systems may also need different dimensions. In any case, it is applicable that the standardized mechanical characteristics of this document and coupling sizes are retained. This fifth edition cancels and replaces the fourth edition published in 1995. This edition includes the following significant technical changes with respect to the previous edition: - wording in Scope changed from "it is recommended" to "it is applicable"; - new normative references added; - electromechanical or mechanical failing load in Clause 4 specified; - new figures added showing profiles.

Isolateurs pour lignes aériennes de tension nominale supérieure a 1 000 V - Éléments d’isolateurs en céramique ou en verre pour réseaux à tension alternative - Caractéristiques des éléments d'isolateurs du type capot et tige

L'IEC 60305:2021 s'applique aux éléments de chaînes d'isolateurs du type à capot et tige ayant des parties isolantes en matière céramique ou en verre et 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 du type à capot et tige soit avec assemblage à rotule, soit avec assemblage à chape et tenon. Le présent document s'applique aux éléments de chaînes d'isolateurs destinés aux lignes aériennes situées dans des régions polluées et non polluées. Pour les isolateurs destinés à être utilisés dans des régions très fortement polluées et dans d'autres conditions environnementales particulières ou extrêmes, il peut être nécessaire de modifier certaines dimensions et il peut être préférable d'utiliser des éléments d'isolateurs ayant des lignes de fuite, des pas et des formes différentes (par exemple, profil plat, hémisphérique, etc.). Les isolateurs destinés à être utilisés sur les réseaux à tension continue peuvent également nécessiter des dimensions différentes. Dans tous les cas, il est possible de retenir les caractéristiques mécaniques normalisées du présent document et les dimensions d'assemblage. Cette cinquième édition annule et remplace la quatrième édition parue en 1995. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - reformulation du domaine d'application: "il est recommandé d’utiliser" a été remplacé par "il est possible de retenir"; - ajout de nouvelles références normatives; - spécification à l'Article 4 de la charge de rupture électromécanique ou mécanique; - ajout de nouvelles figures représentant des profils.

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 dam
