Three-phase oil-immersed distribution transformers 50 Hz, from 50 kVA to 2 500 kVA with highest voltage for equipment not exceeding 36 kV - Part 2-2: Distribution transformers with cable boxes on the high-voltage and/or low-voltage side - Cable boxes type 1 for use on distribution transformers meeting the requirements of EN 50464-2-1

This European Standard specifies the requirements for cable boxes, Type 1, in which the cable cores are terminated. The cable boxes are suitable for use on transformers defined in EN 50464-2-1, "Distribution Transformers with Cable Boxes", for side mounted or cover mounted use. The cable boxes are suitable for operation indoors and outdoors under environmental conditions specified in EN 50464-1. Important design and construction requirements of the cable boxes are given.

Ölgefüllte Drehstrom-Verteilungstransformatoren 50 Hz, 50 kVA bis 2 500 kVA, mit einer höchsten Spannung für Betriebsmittel bis 36 kV - Teil 2-2: Verteilungstransformatoren mit Kabelanschlusskästen auf der Ober- und/oder Unterspannungsseite - Kabelanschlusskästen Typ 1 für Verteilungstransformatoren nach EN 50464-2-1

Diese Norm legt die Anforderungen für Kabelanschlusskästen des Typs 1 fest, in denen die Kabeladern abgeschlossen sind. Die Kabelanschlusskästen sind für den Einsatz an Transformatoren geeignet, wie sie in EN 50464-2-1 für Seitenwandanordnung oder Deckelanordnung definiert sind. Die Kabelanschlusskästen sind für den Innenraum- und Freilufteinsatz unter den in EN 50464-1 festgelegten Umweltbedingungen ge¬eignet. Wichtige Anforderungen für Konstruktion und Bauweise von Kabelanschlusskästen werden angegeben.

Transformateurs triphasés de distribution immergés dans l'huile, 50 Hz, de 50 kVA à 2 500 kVA, de tension la plus élevée pour le matériel ne dépassant pas 36 kV - Partie 2-2: Transformateurs de distribution raccordés par boîtes à câble côté haute tension et/ou côté basse tension - Boîtes à câbles de type 1 pour utilisation sur transformateurs de distribution conformes aux exigences de la EN 50464-2-1

Le présent projet de Norme Européenne spécifie les caractéristiques des boîtes à câbles de Type 1 dans lesquelles les conducteurs des câbles viennent se raccorder. Ces boîtes à câbles sont utilisables sur des transformateurs définis par la EN 50464-2-1, Transformateurs de distribution avec boîtes à câbles, et elles peuvent être disposées sur le côté ou sur le couvercle. Les boîtes à câbles conviennent pour un fonctionnement en intérieur et en extérieur sous les conditions d'environnement spécifiées dans la EN 50464-1.

Trifazni oljni distribucijski transformatorji 50 Hz, od 50 kVA do 2 500 kVA z najvišjo napetostjo naprave do 36 kV – 2-2. del: Distribucijski transformatorji s kabelskimi ohišji na visokonapetostni oziroma nizkonapetostni strani – Kabelska ohišja tip 1 za distribucijske transformatorje, ki izpolnjujejo zahteve standarda EN 50464-2-1

Ta Evropski standard označuje zahteve za kabelske omarice Tipa 1, v katerem so kabelske žile zaključene. Kabelske omarice so primerne za uporabo na transformatorjih, omenjenih v EN 50464-2-1, “Distribucijski Transformatorji s kabelskimi omaricami”, za stransko montažo ali na pokrovu. Kabelske omarice so primerne za delovanje znotraj in zunaj pod okoliškimi pogoji omenjenimi v EN 50464-1. Navedene so pomembne zahteve za sestavo in konstrukcijo kabelskih omaric.
