Railway applications - Rolling Stock - Three-phase shore (external) supply system for rail vehicles and its connectors
This document specifies requirements for the shore supply system for auxiliaries and pre-conditioning and the related intermateable connector pairs. This standard specifies the characteristics of the connectors in order to achieve interoperability at the rolling-stock/shore power supply interface.
This document does not apply to shore supplies to move the rolling stock.
Bahnanwendungen - Fahrzeuge - Dreiphasiges Fremdeinspeisungssystem für Schienenfahrzeuge und zugehörige Steckverbinder
Applications ferroviaires - Matériel roulant - Système d'alimentation à quai (externe) triphasée des véhicules ferroviaires par connecteurs
L'objet du présent document est de spécifier les exigences relatives au système d'alimentation à quai pour les auxiliaires et le préconditionnement, ainsi que les paires de connecteurs accouplables associés. La présente norme spécifie les caractéristiques des connecteurs afin d'assurer l'interopérabilité du matériel roulant au niveau de l'interface matériel roulant/alimentation à quai.
Le présent document ne s'applique pas aux systèmes d'alimentation à quai destinés au déplacement du matériel roulant.
