Railway applications - Rolling stock - Rules for installation of cabling
This document specifies requirements for the installation of cabling on railway vehicles and within electrical enclosures on railway vehicles, including magnetic levitation trains and trolley buses.
NOTE With respect to trolley buses, this document applies to the whole electric traction system, including current collecting circuits, power converters and the respective control circuits. The installation of other circuits is covered by street vehicle standards for example those for combustion driven buses.
This document covers cabling for making electrical connections between items of electrical equipment, including cables, busbars, terminals and plug/socket devices. It does not cover special effect conductors like fibre optic cables or hollow conductors (waveguides).
The material selection criteria given here are applicable to cables with copper conductors.
This document is not applicable to the following:
- special purpose vehicles, such as track-laying machines, ballast cleaners and personnel carriers;
- vehicles used for entertainment on fairgrounds;
- vehicles used in mining;
- electric cars;
- funicular railways.
As the field of cabling in rolling stock is also dealt with in the cable makers’ standard, references are made to EN 50264 series, EN 50306 series, EN 50382 series and EN 50355.
This document applies in conjunction with the relevant product and installation standards. Stricter requirements than those given in this document may be necessary.
Bahnanwendungen - Fahrzeuge - Regeln für die Installation von elektrischen Leitungen
Applications ferroviaires - Matériel roulant - Règles d'installation du câblage
Le présent document définit les exigences relatives à l’installation du câblage sur les véhicules ferroviaires et dans les compartiments électriques sur les véhicules ferroviaires, y compris les trains à lévitation magnétique et les trolleybus.
NOTE En ce qui concerne les trolleybus, le présent document s'applique à l'ensemble du système de traction électrique, y compris les circuits de captage du courant, les convertisseurs de puissance et leurs circuits de commande respectifs. L’installation des autres circuits est traitée par les normes consacrées aux véhicules routiers, par exemple, celles traitant des autobus à moteur à combustion.
Le présent document traite du câblage utilisé pour établir des liaisons électriques entre les divers équipements électriques, y compris les câbles, jeux de barres, bornes et connecteurs mobiles/fixes. Il ne prend pas en compte les conducteurs reposant sur des effets spéciaux, tels que les câbles à fibres optiques ou les conducteurs creux (guides d'ondes).
Les critères de sélection des matériaux, énoncés ci-après, sont applicables aux câbles dotés de conducteurs en cuivre.
Le présent document ne s'applique pas à ce qui suit :
– véhicules à usage spécial, tels que machines de pose de voie, de nettoyage de ballast et de transport du personnel ;
– véhicules utilisés à des fins de loisirs sur les champs de foire ;
– véhicules de mines ;
– véhicules électriques ;
– funiculaires.
Comme le domaine du câblage dans le matériel roulant est aussi traité dans les normes des câbliers, référence est faite aux normes des séries EN 50264, EN 50306, EN 50382 et à la norme EN 50355.
Le présent document s'applique en association avec les normes de produit et d'installation appropriées. Des exigences plus strictes que celles édictées dans le présent document, peuvent s'avérer nécessaires.
