EN 50264-2-2 specifies requirements for, and constructions and dimensions of, multicore cables of the following types and voltage ratings: 300/500 V screened or unscreened (1 mm², 1,5 mm² and 2,5 mm², number of cores from 2 to 40); 0,6/1 kV screened or unscreened (1,5 mm² to 50 mm², 2, 3 and 4 cores).

Bahnanwendungen - Starkstrom- und Steuerleitungen für Schienenfahrzeuge mit verbessertem Verhalten im Brandfall -- Teil 2-2: Leitungen mit vernetzter elastomerer Isolierung - Mehr- und vieladrige Leitungen

EN 50264-2-2 legt Anforderungen an und Aufbauten und Abmessungen von mehr- und vieladrigen Leitungen für folgende Bauarten und Nennspannungen fest: • 300 V/500 V mit oder ohne Schirm (1 mm², 1,5 mm² und 2,5 mm², Aderzahlen von 2 bis 40); • 0,6 kV/1 kV mit oder ohne Schirm (1,5 mm² bis 50 mm², 2, 3 und 4 Adern). ANMERKUNG Nicht alle Leiterquerschnitte oder Aderzahlen sind für jede Bauart festgelegt. 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 50264-2-2 sollte in Verbindung mit Teil 1 „Allgemeine Anforderungen“ gelesen werden.

Tous les câbles possèdent une âme en cuivre étamé de classe 5 selon la EN 60228, une enveloppe isolante 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 de 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 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 50264-2-2 conjointement avec la Partie 1 "Prescriptions générales".

Introduction
The EN 50264 series covers a range of 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
and EN 50343. 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.
Part 1, “General requirements”, contains a more extensive introduction to EN 50264, and should be read in
conjunction with this Part 2-2.

1 Scope
EN 50264-2-2 specifies requirements for, and constructions and dimensions of, multicore cables of the
following types and voltage ratings:
• 300/500 V screened or unscreened (1 mm², 1,5 mm² and 2,5 mm², number of cores from 2 to 40);
• 0,6/1 kV screened or unscreened (1,5 mm² to 50 mm², 2, 3 and 4 cores).
NOTE  Not all conductor sizes or number of cores are specified for every type.
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 50264-2-2 should be read in conjunction with Part 1 “General requirements”.

For the purposes of this document, the terms and definitions given in EN 50264-1 apply.
4 Rated voltage
The rated voltage for multicore cables shall be as follows:
a) 300/500 V (1 mm² to 2,5 mm²) control cables;
b) 0,6/1 kV (1,5 mm² to 50 mm²) power cables.

5.1 Marking of cable
Cables shall be marked with the following:
• manufacturer’s name;
• EN reference;
• voltage rating (U );
o
• number of cores and conductor size;
• a code designation according to Annex A.
If a cable is screened, an additional letter, S, shall be added.
