Bushings for transformers and reactor cable boxes not exceeding 36 kV

This document is applicable to insulated bushings, excluding those plug-in bushings specified by EN 50180 series, for use in air insulated, shroud insulated and fully insulated cable boxes for liquid filled transformers and reactors for rated voltages up to 36 kV, and rated currents up to 4 000 A at frequencies from 15 Hz to 60 Hz.

Durchführungen für Kabelanschlusskästen von Transformatoren und Drosselspulen bis 36 kV

Traversées pour boîtes à câbles de transformateurs et bobines d'inductance ne dépassant pas 36 kV

Le présent document s'applique aux traversées isolées à l'exception des traversées de type embrochable spécifiées dans la série EN 50180, destinées à être utilisées dans les boîtes à câbles à isolement dans l'air, à isolement renforcé et totalement isolées des transformateurs remplis de liquide et des bobines d'inductance de tension assignée jusqu'à 36 kV et d'intensité assignée jusqu'à 4 000 A à des fréquences comprises entre 15 Hz et 60 Hz.

Skoznjiki za transformatorje in reaktorska kabelska ohišja do vključno 36 kV

Ta dokument se uporablja za izolirane skoznjike (razen vtičnih skoznjikov, opredeljenih v skupini standardov EN 50180), ki se uporabljajo v zračno izoliranih kabelskih omaricah, kabelskih omaricah, izoliranih z oplaščenjem, in popolnoma izoliranih kabelskih omaricah za tekočinske transformatorje in reaktorje z nazivno napetostjo do 36 kV ter nazivnim tokom do 4000 A pri frekvencah od 15 Hz do 60 Hz.
