Test requirements for low voltage aerial bundled cable accessories - Part 4: Connectors
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. This Part 4 applies to connectors used for the electrical connection of ABC. The connectors are designed to be installed on ABC defined in HD 626. Tests described in this document are type tests. 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.
Prüfanforderungen für Bauteile für isolierte Niederspannungsfreileitungen - Teil 4: Verbinder
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. Dieser Teil 4 gilt für Verbinder und Kabelanschlüsse (im Folgenden nur als Verbinder bezeichnet), die zum elektrischen Anschluss von ABC verwendet werden. Diese Verbinder sind für die Montage an ABC nach HD 626 ausgelegt. Die in diesem Dokument beschriebenen Prüfungen sind Typprüfungen. 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.

Cette Partie 4 s’applique aux raccords utilises pour la connexion électrique des câbles torsadés aériens. Les raccords sont destinés à être installés sur les câbles torsadés aériens définis dans le HD 626. Les essais décrits dans ce document sont des essais de type. 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 à l’organisme compétent d’évaluation de conformité, de démontrer que l’ancienne conformité peu 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.
