EN 50180-2:2015

Bushings above 1 kV up to 52 kV and from 250 A to 3,15 kA for liquid filled transformers - Part 2: Requirement for bushing components

This European Standard should be considered in factual context with EN 50180 only. The dimensional supplements are related to figures and tables of EN 50180. To enable a better understanding of additional information some tables from EN 50180 are used and extended. This European Standard may now be used also for bushings with a highest voltage of 52 kV. Figures for the details of the components and the related tables are added according to the extended range of voltage.

Durchführungen über 1 kV bis 52 kV und von 250 A bis 3,15 kA für flüssigkeitsgefüllte Transformatoren - Teil 2: Anforderungen an Einzelteile der Durchführungen

Diese Europäische Nom ist nur im Zusammenhang mit EN 50180 zu betrachten. Die Ergänzungen zu den Abmessungen nehmen Bezug auf die Bilder und Tabellen in EN 50180. Zum besseren Verständnis der zusätzlichen Informationen werden einige Tabellen aus DIN EN 50180 wiederholt und entsprechend ergänzt. Dieser Standard kann jetzt auch auf Durchführungen mit einer höchsten Spannung von 52kV angewendet werden. Die Abbildungen der Einzelheiten und die zugehörigen Tabellen wurden ergänzt gemäß dem erweiterten Spannungsbereich.

Traversées de tensions supérieures à 1 kV jusqu'à 52 kV et de 250 A à 3,15 kA pour transformateurs immergés dans un liquide - Partie 2: Exigences relatives aux composants de traversée

Il convient de ne considérer la présente norme européenne que dans le cadre du contexte factuel avec l'EN 50180. Les dimensions complémentaires spécifiées se rapportent aux figures et aux tableaux de l'EN 50180. Afin de mieux comprendre les informations complémentaires spécifiées, certains tableaux de l'EN 50180 sont utilisés et étendus. La présente norme européenne peut désormais être également utilisée pour les traversées présentant une tension plus élevée de 52 kV. Les figures relatives aux détails des composants et les tableaux associés sont ajoutés selon la plage étendue des tensions correspondantes.

Ta evropski standard se upošteva samo v dejanskem okviru standarda EN 50180-1. Dodatki
glede mer so povezani s slikami in preglednicami iz standarda EN 50180-1. Za boljše razumevanje dodatnih informacij so uporabljene in razširjene nekatere preglednice iz standarda EN 50180-1.
Ta evropski standard se lahko zdaj uporablja tudi za skoznjike z najvišjo napetostjo 52 kV. Slike za podrobnosti o komponentah in povezane preglednice so dodane v skladu z razširjenim razponom napetosti.

to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2018-08-10
standards conflicting with this
document have to be withdrawn
This document supplements EN 50180-1:2015 by design details for components, described in the withdrawn
standards DIN 42531, DIN 42532 and DIN 42533 and it is important for utilities to manage interchangeability.
This document should document major additional information of the withdrawn standards.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such patent rights.

EN 50180 "Bushings above 1 kV up to 52 kV and from 250 A to 3,15 kA for liquid filled transformers" consists
of the following parts:
– Part 1: General requirements for bushings;

– Part 2: Requirement for bushing components;

– Part 3: Requirements for bushing fixations.

1 Scope
This European Standard should be considered in factual context with EN 50180-1 only. The dimensional
supplements are related to figures and tables of EN 50180-1. To enable a better understanding of additional
information some tables from EN 50180-1 are used and extended.
This European Standard may now be used also for bushings with a highest voltage of 52 kV. Figures for the
details of the components and the related tables are added according to the extended range of voltage.
