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 50588-2 "Transformatoren mit Kabelanschlusskästen" für Seitenwandanordnung oder Deckelanordnung definiert sind. Die Kabelanschlusskästen sind für den Innenraum- und Freilufteinsatz unter den in EN 50588-1 festgelegten Umweltbedingungen geeignet. Wichtige Anforderungen für Konstruktion und Bauweise von Kabelanschlusskästen werden angegeben.

Transformateurs 50 Hz de moyenne puissance, de tension la plus élevée pour le matériel ne dépassant pas 36 kV - Partie 3: Transformateurs raccordés par boîtes à câble côté haute tension et/ou côté basse tension - Boîtes à câbles de type 1 pour utilisation pour transformateurs conformes aux exigences de la EN 50588-2

La présente Norme européenne spécifie les exigences relatives aux boîtes à câbles de Type 1, dans lesquelles se terminent les âmes de câble. Les boîtes à câbles sont adaptées à une utilisation sur les transformateurs définis dans l'EN 50588-2, "Transformateurs avec boîtes à câbles", à montage latéral ou sur le couvercle. Les boîtes à câbles sont adaptées à une utilisation intérieure et extérieure dans les conditions d'environnement spécifiées dans l'EN 50588-1. Des exigences importantes en matière de conception et de construction des boîtes à câbles sont données.

Močnostni transformatorji srednje moči 50 Hz z najvišjo napetostjo naprave do 36 kV - 3. del: Transformatorji s kabelskimi ohišji na visokonapetostni oziroma nizkonapetostni strani - Kabelska ohišja tipa 1 za transformatorje, ki izpolnjujejo zahteve standarda EN 50588-2

Ta evropski standard določa zahteve za kabelske omarice tipa 1, v katerih se kabelske žile končajo. Kabelske omarice so primerne za uporabo v transformatorjih, določenih v EN 50588-2, »Transformatorji s kabelskimi omaricami«, za namestitev ob strani ali na pokrov. Kabelske omarice so primerne za uporabo znotraj in zunaj pod okoljskimi pogoji, določenimi v standardu EN 50588-1.
Navedene so pomembne zahteve za projektiranje in konstrukcijo kabelskih omaric.
