EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. The objective is to provide a method of testing the suitability of accessories when used under normal operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626. There is variation between the different ABC specifications provided by HD 626, and tests carried out on one of the ABC types may not be completely applicable to ABC of a different specification. Therefore, the purchasers of accessories tested to this European Standard, must ensure that all their requirements are met.
Prüfanforderungen für Bauteile für isolierte Niederspannungsfreileitungen – Teil 1: Allgemeines
EN 50483 (Reihe) gilt für oberirdisch zu verwendende Bauteile zum Abspannen, Aufhängen und Verbinden von iso¬lierten Freileitungen (en.: Aerial Bundled Cables, ABC) für eine Nennspannung von U0/U (Um): 0,6/1 (1,2) kV. Der mit dieser Norm verbundene Zweck besteht darin, ein Verfahren zur Verfügung zu stellen, mit dem die Eignung der Bauteile zur Verwendung mit isolierten Niederspannungsfreileitungen (ABC) nach HD 626 unter normalen Betriebsbedingungen geprüft werden kann. Es gibt Abweichungen zwischen den unterschiedlichen nach HD 626 erstellten ABC-Spezifikationen, und Prü¬fungen, die an einer der unterschiedlichen ABC-Bauarten durchgeführt wurden, sind möglicherweise nicht in vollem Umfang auf ABC einer anderen Spezifikation anwendbar. Daher müssen Auftraggeber von nach dieser Europäischen Norm geprüften Bauteilen sicherstellen, dass alle ihre Anforderungen erfüllt werden. ANMERKUNG Durch diese Europäische Norm verlieren bestehende Zulassungen nicht ihre Gültigkeit, die auf der Basis nationaler Normen und Spezifikationen und/oder anhand des Nachweises zufriedenstellender Ergebnisse im Einsatz erfolgte. Jedoch gelten nach früheren Normen oder Spezifikationen zugelassene Produkte nicht als nach dieser Europäischen Norm zugelassen. Es ist möglich, basierend auf einer Vereinbarung zwischen Lieferanten und Auftraggeber und/oder der zuständigen Stelle für Konformitätsbewertungen, nachzuweisen, dass die Konformität mit der früheren Norm für den Anspruch auf Konformität mit dieser Norm verwendet werden kann, vorausgesetzt, eine Bewertung aller zusätzlichen Typprüfungen, deren Durchführung erforderlich sein könnte, ist erfolgt. Alle zusätzlichen Prüfungen, die Teil einer Prüffolge sind, dürfen nicht separat durchgeführt werden. Die klimatischen Bedingungen variieren in Europa in erheblichem Maße, und um diesen unterschiedlichen geografischen Klimabedingungen gerecht werden zu können, ist eine entsprechende Reihe von Prüfungen erforderlich. An dieser Stelle wird eine Reihe zusätzlicher freiwilliger Prüfungen festgelegt, die den verschie-denen klimatischen Anforderungen entsprechen und zwischen Kunden und Lieferanten vereinbart werden sollten (siehe Anhang C in EN 50483-6). Zweck des vorliegenden Teil 1 dieser Norm ist es, die allgemeinen Aspekte der in den obigen Anwendungs-bereich fallenden Produkte festzulegen.
Prescriptions relatives aux essais des accessoires pour réseaux aériens basse tension torsadés -- Partie 1: Généralités
La série EN 50483 s’applique aux équipements de lignes aériennes pour ancrage, suspension et raccordement des câbles torsadés aériens de tension assignée U0/U (Um): 0,6/1 (1,2) kV. L’objectif est de fournir une méthode pour tester l’aptitude des accessoires lorsqu’ils sont utilisés dans des conditions normales de service sur les câbles torsadés aériens basse tension définis dans le HD 626. Il y a des écarts entre les différentes spécifications des torsades décrites dans le HD 626 et les essais effectués sur un des types de torsade peuvent ne pas être complètement applicables à une torsade d’une autre spécification. En conséquence, les acheteurs d’accessoires testés selon cette Norme Européenne doivent s’assurer que toutes leurs exigences sont satisfaites. NOTE La présente Norme Européenne n’annule pas les approbations existantes des produits obtenues sur la base de normes ou spécifications nationales et/ou obtenues par la démonstration de performance satisfaisante en service. Cependant, des produits approuvés selon de telles normes ou spécifications nationales ne peuvent directement réclamer l’approbation à la présente Norme Européenne. Il peut être possible, sous réserve d’un accord entre le fournisseur et l’acheteur et/ou l’organisme compétent d’évaluation de conformité, de démontrer que l’ancienne conformité peut être utilisée pour se réclamer de la conformité à la présente norme, pourvu qu’une évaluation soit faite à partir de tout essai additionnel de type qui pourrait être nécessaire. Un tel essai additionnel faisant partie d’une séquence d’essais ne peut être réalisé séparément. Le climat diffère à travers l’Europe et pour s’adapter aux différentes conditions climatiques, il est nécessaire de proposer une gamme d’essais pour y répondre. Une gamme des essais optionnels et additionnels est fournie pour satisfaire les besoins climatiques variables et ces essais devraient être réalisés selon accord entre client et fournisseur (voir l’Annexe C dans la EN 50483-6). Le but de cette Partie 1 est de définir les aspects communs des produits inclus dans le domaine d’application ci-dessus

1 Scope
EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial
bundled cables (ABC) of rated voltage U /U (U ): 0,6/1 (1,2) kV.
0 m
The objective is to provide a method of testing the suitability of accessories when used under normal
operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626.
There is variation between the different ABC specifications provided by HD 626, and tests carried out
on one of the ABC types may not be completely applicable to ABC of a different specification.
Therefore, the purchasers of accessories tested to this European Standard, must ensure that all their
requirements are met.
NOTE This European Standard does not invalidate existing approvals of products achieved on the basis of national standards
and specifications and/or the demonstration of satisfactory service performance. However, products approved according to such
national standards or specifications cannot directly claim approval to this European Standard. It may be possible, subject to
agreement between supplier and purchaser, and/or the relevant conformity assessment body, to demonstrate that conformity to
the earlier standard can be used to claim conformity to this standard, provided an assessment is made of any additional type
testing that may need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done
separately.
Climate differs across Europe and in order to meet the differing geographic climatic conditions it is
necessary to provide a range of tests to meet these variations. A range of optional, additional tests is
provided to meet the varying climatic needs and these should be agreed between the customer and
the supplier (see Annex C in EN 50483-6).
The purpose of this Part 1 is to define the common aspects of the products included in the above
scope.
