CAN/CSA C22.3 NO. 60826-2010

CAN/CSA-C22.3 NO. 60826-10 - Design criteria of overhead transmission lines (Adopted CEI/IEC 60826:2003, third edition, 2003-10, with Canadian deviations) | CritFres de conception des lignes aTriennes de transport (norme CEI/IEC 60826:2003 adoptTe, troisiFme Tdition, 2003-10, avec exigences propres au Canada)

Preface

This is the second edition of CAN/CSA-C22.3 No. 60826, Design criteria of overhead transmission lines, which is an adoption, with Canadian deviations, of the identically titled CEI/IEC (Commission ╔lectrotechnique Internationale/International Electrotechnical Commission) Standard 60826 (third edition, 2003-10). This Standard supersedes the previous edition published in 2006 as CAN/CSA-C22.3 No. 60826 (adopted CEI/IEC 60826:2003).

Scope

This International Standard specifies the loading and strength requirements of overhead lines derived from reliability based design principles. These requirements apply to lines 45 kV and above, but can also be applied to lines with a lower nominal voltage.

This standard also provides a framework for the preparation of national standards dealing with overhead transmission lines, using reliability concepts and employing probabilistic or semiprobabilistic methods. These national standards will need to establish the local climatic data for the use and application of this standard, in addition to other data that are country specific.

Although the design criteria in this standard apply to new lines, many concepts can be used to address the reliability requirements for refurbishment and uprating of existing lines.

This standard does not cover the detailed design of line components such as towers, foundations, conductors or insulators.

PrΘface

Ce document constitue la deuxiΦme Θdition de la CAN/CSA-C22.3 n║ 60826, CritΦres de conception des lignes aΘriennes de transport. Il s'agit de l'adoption, avec exigences propres au Canada, de la norme CEI/IEC (Commission ╔lectrotechnique Internationale/International Electrotechnical Commission) 60826 (troisiΦme Θdition, 2003-10), qui porte le mΩme titre. Cette norme remplace l'Θdition prΘcΘdente publiΘe en 2006 qui portait la dΘsignation CAN/CSA-C22.3 n║ 60826 (norme CEI/IEC 60826:2003 adoptΘe).

Domaine d'application

La prΘsente Norme internationale spΘcifie les critΦres de charge et de rΘsistance mΘcanique des lignes aΘriennes en s'inspirant de principes de conception fondΘs sur la fiabilitΘ. Ces critΦres sont valables pour les lignes prΘsentant une tension nominale supΘrieure ou Θgale α 45 kV, mais peuvent aussi s'appliquer aux lignes dont la tension nominale est plus faible.

La prΘsente norme sert Θgalement de cadre α l'Θlaboration de normes nationales traitant des lignes de transport α partir de notions de fiabilitΘ et au moyen de mΘthodes probabilistes ou semi-probabilistes. Il incombera α ces normes nationales de dΘterminer les donnΘes climatiques locales α prendre en compte pour l'utilisation et l'application de la prΘsente norme, en sus des autres donnΘes spΘcifiquement nationales.

Les critΦres de calcul ΘnoncΘs dans la prΘsente norme s'appliquent aux lignes nouvelles, mais un grand nombre des notions abordΘes peuvent Θgalement servir α rΘpondre aux exigences de fiabilitΘ des lignes existantes qui ont besoin d'Ωtre rΘnovΘes ou dont les performances sont α amΘliorer.

Cette norme ne porte pas sur les dΘtails de conception de composants de lignes tels que pyl⌠nes, fondations, conducteurs ou isolateurs.
