Annotation of standard text IEC 60305-ed.5.0 :
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. LIEC 60305:2021 sapplique aux elements de chaines disolateurs du type a capot et tige ayant des parties isolantes en matiere ceramique ou en verre et destines aux lignes aeriennes fonctionnant en courant alternatif a une tension nominale superieure a 1 000 V et a une frequence au plus egale a 100 Hz. Elle sapplique egalement aux isolateurs du meme type utilises dans les postes. Le present document sapplique aux elements de chaines disolateurs du type a capot et tige soit avec assemblage a rotule, soit avec assemblage a chape et tenon. Le present document sapplique aux elements de chaines disolateurs destines aux lignes aeriennes situees dans des regions polluees et non polluees. Pour les isolateurs destines a etre utilises dans des regions tres fortement polluees et dans dautres conditions environnementales particulieres ou extremes, il peut etre necessaire de modifier certaines dimensions et il peut etre preferable dutiliser des elements disolateurs ayant des lignes de fuite, des pas et des formes differentes (par exemple, profil plat, hemispherique, etc.). Les isolateurs destines a etre utilises sur les reseaux a tension continue peuvent egalement necessiter des dimensions differentes. Dans tous les cas, il est possible de retenir les caracteristiques mecaniques normalisees du present document et les dimensions dassemblage. Cette cinquieme edition annule et remplace la quatrieme edition parue en 1995. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - reformulation du domaine dapplication: "il est recommande d’utiliser" a ete remplace par "il est possible de retenir"; - ajout de nouvelles references normatives; - specification a lArticle 4 de la charge de rupture electromecanique ou mecanique; - ajout de nouvelles figures representant des profils.
