Railway applications - Railway rolling stock power and control cables having special fire performance - Part 3-1: Cables with crosslinked elastomeric insulation with reduced dimensions - Single core cables

EN 50264-3-1 specifies requirements for, and constructions and dimensions of, single core cables of the following types and voltage ratings: • 0,6/1 kV unscreened, unsheathed (1 mm2 to 400 mm2); • 1,8/3 kV unscreened, unsheathed (1,5 mm2 to 400 mm2); • 1,8/3 kV unscreened, sheathed (1,5 mm2 to 400 mm2); • 3,6/6 kV unscreened, sheathed (2,5 mm2 to 400 mm2). All cables have class 5 tinned copper conductors to EN 60228, halogen-free insulation and halogen-free sheath. They are for use in railway rolling stock as fixed wiring, or wiring where limited flexing in operation is encountered. The requirements provide for a continuous conductor temperature not exceeding 90° C and a maximum temperature for short circuit conditions of 200 °C based on a duration of 5 s. Under fire conditions the cables exhibit special performance characteristics in respect of maximum permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases. EN 50264-3-1 should be read in conjunction with Part 1 “General requirements”.

Bahnanwendungen - Starkstrom- und Steuerleitungen für Schienenfahrzeuge mit verbessertem Verhalten im Brandfall - Teil 3-1: Leitungen mit vernetzter elastomerer Isolierung mit reduzierten Abmessungen - Einadrige Leitungen

EN 50264-3-1 legt Anforderungen an und Aufbauten und Abmessungen von einadrigen Leitungen für folgende Bauarten und Nennspannungen fest: – 0,6/1 kV ohne Schirm, ohne Mantel (1 mm2 bis 400 mm2); – 1,8/3 kV ohne Schirm, ohne Mantel (1,5 mm2 bis 400 mm2); – 1,8/3 kV ohne Schirm, mit Mantel (1,5 mm2 bis 400 mm2); – 3,6/6 kV ohne Schirm, mit Mantel (2,5 mm2 bis 400 mm2). Alle Leitungen haben einen verzinnten Kupferleiter Klasse 5 nach EN 60228, eine halogenfreie Isolierung und gegebenenfalls einen halogenfreien Mantel. Sie sind für feste Verlegung im Schienenfahrzeug bestimmt oder für Verdrahtungen, bei denen im Betrieb begrenzt mit Bewegungen gerechnet werden muss. Die Anforderungen berücksichtigen eine dauernde Leitertemperatur von nicht mehr als 90 °C und eine maximale Kurzschlusstemperatur von 200 °C bei einer Dauer von 5 Sekunden. Unter Brandbedingungen zeigen die Leitungen besondere Leistungsmerkmale hinsichtlich der maximal zulässigen Weiterleitung der Flammen (Ausbreitung der Flammen) und der höchsten zulässigen Emission von Rauch und giftigen Gasen. EN 50264-3-1 sollte in Verbindung mit Teil 1 „Allgemeine Anforderungen“ gelesen werden.

Applications ferroviaires - Câbles de puissance et de contrôle à comportement au feu spécifié pour matériel roulant ferroviaire - Partie 3-1: Câbles à enveloppe isolante réticulée de faibles dimensions - Câbles monoconducteurs

La EN 50264-3-1 spécifie les prescriptions, les constructions et les dimensions des câbles monoconducteurs des types et tensions assignées suivants: - 0,6/1 kV sans blindage ni gaine (de 1 mm2 à 400 mm2); - 1,8/3 kV sans blindage ni gaine (de 1,5 mm2 à 400 mm2); - 1,8/3 kV gainé sans blindage (de 1,5 mm2 à 400 mm2); - 3,6/6 kV gainé sans blindage (de 2,5 mm2 à 400 mm2). Tous les câbles monoconducteurs possèdent une âme en cuivre étamé de classe 5 selon la EN 60228, une isolation et une gaine sans halogènes. Ils sont destinés aux installations fixes ou soumis à de faibles flexions en service des matériels roulants ferroviaires. Les prescriptions sont basées pour une température permanente à l’âme ne dépassant pas 90 °C et à une température maximale de 200 °C pour une durée de 5 s en cas de court-circuit. Les câbles monoconducteurs présentent, en cas d’incendie, des performances particulières de propagation maximale admissible de la flamme (longueur brûlée) et d’émission de fumées et de gaz toxiques. Il est recommandé de lire la EN 50264-3-1 conjointement avec la Partie 1 “Prescriptions générales”.

Introduction
The EN 50264 series covers cables, based upon halogen free materials, for use in railway rolling stock. It is
divided into 5 parts under the generic title “Railway applications - Railway rolling stock power and control
cables having special fire performance”.
– Part 1 General requirements;
– Part 2-1 Cables with crosslinked elastomeric insulation – Single core cables;
– Part 2-2 Cables with crosslinked elastomeric insulation – Multicore cables;
– Part 3-1 Cables with crosslinked elastomeric insulation with reduced dimensions – Single core
cables;
– Part 3-2 Cables with crosslinked elastomeric insulation with reduced dimensions – Multicore cables.
Information regarding selection and installation of cables, including current ratings can be found in EN 50355
(Guide to use) and EN 50343 (Rules for installation of cabling). The procedure for selection of cable cross-
sectional area, including reduction factors for ambient temperature and installation type, is described in EN
50343.
Special test methods referred to in EN 50264 are given in EN 50305.
The cables in Part 3-1 may also be used in EN 50264-3-2 to build up multicore sheathed cables.
Part 1, "General requirements", contains a more extensive introduction to EN 50264, and should be read in
conjunction with this Part 3-1.

- 5 - EN 50264-3-1:2008
1 Scope
EN 50264-3-1 specifies requirements for, and constructions and dimensions of, single core cables of the
following types and voltage ratings:
2 2
• 0,6/1 kV unscreened, unsheathed (1 mm to 400 mm );
2 2
• 1,8/3 kV unscreened, unsheathed (1,5 mm to 400 mm );
2 2
• 1,8/3 kV unscreened, sheathed (1,5 mm to 400 mm );
2 2
• 3,6/6 kV unscreened, sheathed (2,5 mm to 400 mm ).
All cables have class 5 tinned copper conductors to EN 60228, halogen-free insulation and halogen-free
sheath. They are for use in railway rolling stock as fixed wiring, or wiring where limited flexing in operation is
encountered. The requirements provide for a continuous conductor temperature not exceeding 90° C and a
maximum temperature for short circuit conditions of 200 °C based on a duration of 5 s.
Under fire conditions the cables exhibit special performance characteristics in respect of maximum
permissible flame propagation (flame spread) and maximum permissible emission of smoke and toxic gases.
EN 50264-3-1 should be read in conjunction with Part 1 “General requirements”.
