EN 61952:2008

Insulators for overhead lines - Composite line post insulators for A.C. systems with a nominal voltage greater than 1 000 V - Definitions, test methods and acceptance criteria

IEC 61952:2008 applies to composite line post insulators consisting of a load-bearing, cylindrical, insulating solid core made up of fibres - usually glass - in a resin-based matrix, a housing (outside the insulating core) made of elastomer material (e.g. silicone or ethylene-propylene) and end fittings permanently attached to the insulating core. The object of this standard is to - define the terms used, - prescribe test methods, - prescribe acceptance or failure criteria. This standard does not include requirements dealing with the choice of insulators for specific operating conditions. This edition includes the following significant technical changes with respect to the previous edition: - removal of tests procedures now given in IEC 62217; - inclusion of clauses on tolerances, environmental conditions, transport, storage and installation; - changes in the parameters determining the need to repeat design and type tests; and - modification of the specification of load application in bending tests to simplify testing.

Isolateurs pour lignes aériennes - Isolateurs composites rigides à socle pour systèmes à courant alternatif de tension nominale supérieure à 1 000 V - Définitions, méthodes d'essai et critères d'acceptation

La CEI 61952:2008 est applicable aux isolateurs composites rigides à socle constitués d'un noyau isolant cylindrique supportant la charge, composé de fibres - habituellement en verre - dans une matrice à base de résine, d'un revêtement (extérieur au noyau isolant) en matériau élastomère (par exemple silicone ou éthylène-propylène) et d'armatures d'extrémité reliées de façon permanente au noyau isolant. La présente norme a pour objet: - de définir les termes employés, - de fixer les méthodes d'essai, - de fixer les critères d'acceptation ou de rejet d'une fourniture. Cette norme n'inclut pas d'exigences relatives au choix des isolateurs pour des conditions de service spécifiques. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - suppression des procédures d'essai qui sont maintenant données dans la CEI 62217; - ajout d'articles concernant les tolérances, les conditions environnementales, le transport, le stockage et l'installation; - modification des paramètres déterminant la nécessité de répéter les essais de conception et de type et modification des exigences d'application des charges dans les essais de flexion pour faciliter les essais.
