Railway applications - Railway rolling stock high temperature power cables having special fire performance - Part 2: Single core silicone rubber insulated cables for 120 °C or 150 °C

Part 2 of EN 50382 specifies requirements for, and constructions and dimensions of, single core cables of the following types and voltage ratings: – 1,8/3 kV unscreened, unsheathed with or without textile braid (1,5 mm² to 400 mm²); – 1,8/3 kV unscreened, sheathed (1,5 mm² to 400 mm²); – 3,6/6 kV unscreened, unsheathed with or without textile braid (2,5 mm² to 400 mm²); – 3,6/6 kV unscreened, sheathed (2,5 mm² to 400 mm²). All cables have class 5 or class 6 tinned or plain copper conductors to EN 60228, halogen-free insulation and where applicable 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 120 °C or 150 °C and a maximum temperature for short circuit conditions of either 250 °C or 350 °C based on a duration of 5 s. When the insulating compounds and sheath specified in this standard which are thermally capable of operating at 150 °C are used with tinned conductors, the maximum operating temperature is limited to 120 °C and, for the same technical reason, the maximum short circuit temperature is limited to 250 °C. The choice of sheath may also limit the maximum operating temperature to 120 °C. A textile braid may be included in the insulation or applied at its surface to unsheathed cables. 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. This Part 2 of EN 50382 should be used in conjunction with Part 1 “General requirements”.

Bahnanwendungen - Hochtemperaturkabel und -leitungen für Schienenfahrzeuge mit verbessertem Verhalten im Brandfall - Teil 2: Einadrige silikonisolierte Leitungen für 120 °C oder 150 °C

Teil 2 von EN 50382 legt Anforderungen an und Aufbauten und Abmessungen von einadrigen Leitungen für folgende Bauarten und Nennspannungen fest: – 1,8/3 kV ohne Schirm, ohne Mantel, mit oder ohne Textilgeflecht (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, ohne Mantel, mit oder ohne Textilgeflecht (2,5 mm2 bis 400 mm2); – 3,6/6 kV ohne Schirm, mit Mantel (2,5 mm2 bis 400 mm2). Alle Leitungen haben einen verzinnten oder blanken Kupferleiter Klasse 5 oder Klasse 6 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 120 °C oder 150 °C und eine maximale Kurzschlusstemperatur von entweder 250 °C oder 350 °C bei einer Dauer von 5 s. Wenn die in dieser Norm festgelegten Isoliermischungen und der Mantel für eine Betriebstemperatur von 150 °C geeignet sind, mit verzinnten Leitern verwendet werden, beträgt die maximale Betriebstemperatur 120 °C und aus denselben technischen Gründen ist die maximale Kurzschlusstemperatur bei verzinnten Kupferleitern auf 250 °C begrenzt. Durch die Wahl des Mantels kann die Betriebstemperatur auch auf 120 °C begrenzt werden. Ein Textilgeflecht darf sich in der Isolierung befinden oder auf der Oberfläche von Leitungen ohne Mantel aufgebracht werden. 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. . Teil 2 von EN 50382 sollte in Verbindung mit Teil 1 „Allgemeine Anforderungen“ benutzt werden.

Applications ferroviaires - Câbles pour matériel roulant ferroviaire ayant des performances particulières de comportement au feu - Partie 2: Câbles monoconducteurs isolés au silicone pour 120 °C ou 150 °C

La présente Partie 2 de la EN 50382 spécifie les prescriptions, la construction et les dimensions, des câbles monoconducteurs de type et de tension assignée suivantes: – 1,8/3 kV non écrantés, non gainés, avec ou sans tresse textile (1,5 mm² à 400 mm²); – 1,8/3 kV non écrantés, gainés (1,5 mm² à 400 mm²); – 3,6/6 kV non écrantés, non gainés avec ou sans tresse textile (2,5 mm² à 400 mm²); – 3,6/6 kV non écrantés, gainés (2,5 mm² à 400 mm²). Tous les câbles possèdent une âme en cuivre étamé ou non, de classe 5 ou 6 selon la EN 60228, une enveloppe isolante sans halogènes et lorsqu’applicable, 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 120 °C ou 150 °C et à une température maximale de 250 °C ou 350 °C pour une durée de 5 s en cas de court-circuit. Bien que les matériaux d’isolation et de gainage spécifiés dans la présente norme soient thermiquement capables de fonctionner à 150 °C, la température de fonctionnement est limitée à 120 °C lorsque les âmes sont étamées et pour les mêmes raisons techniques, la température maximale de court-circuit est limitée à 250 °C pour les âmes étamées. Le choix de la gaine peut aussi limiter la température de fonctionnement à 120 °C. Une tresse textile peut être incluse dans l’enveloppe isolante ou appliquée en surface pour les câbles non gainés. 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 d’utiliser la Partie 2 de la EN 50382 conjointement avec la Partie 1 “Prescriptions générales”.

Overview

EN 50382-2:2008 is a CLC (CENELEC) standard specifying requirements for single‑core silicone rubber insulated high‑temperature power cables used in railway rolling stock. It covers unsheathed and sheathed single‑core cables for rated voltages 1.8/3 kV and 3.6/6 kV, designed for continuous conductor temperatures of 120 °C or 150 °C and with defined short‑circuit temperature limits (5 s duration). The standard focuses on cables with halogen‑free insulation (and where applicable halogen‑free sheaths) that provide special fire performance in terms of flame propagation, smoke density and toxic gas emission.

Key topics and technical requirements

• Cable types & ratings: 1.8/3 kV and 3.6/6 kV single‑core constructions; conductor cross‑sections from small signal sizes up to 400 mm² depending on type.
• Conductors: Class 5 or class 6 copper conductors per EN 60228 - plain copper for 150 °C ratings, tinned copper typically used for 120 °C rated cables (special limitations apply when mixing materials).
• Insulation & sheath compounds: Silicone rubber insulation compounds defined for extra/low temperature and oil resistance (compound types EI111/EI112); sheath compound choices (EM105/EM106/EM107) which may limit maximum operating temperature.
• Thermal limits: Continuous conductor temperature 120 °C or 150 °C; short‑circuit peak temperatures of 250 °C or 350 °C for 5 s depending on construction and materials. Note: using certain insulating/sheath compounds with tinned conductors restricts the maximum operating temperature to 120 °C.
• Fire performance: Limits on flame spread, smoke emission and toxic gas generation under fire conditions; defined test methods (referenced in EN 50305, EN 60332, EN 61034).
• Constructional options: Permitted textile braid (internal or external), optional conductor screening, separator tapes and sheathed/unsheathed variants.
• Marking & identification: Requirements for cable marking (EN reference, voltage, conductor size, code designation, conductor temperature) and color rules for insulation/sheath.
• Testing: Comprehensive mechanical, electrical, ageing and fire tests (e.g., voltage, insulation resistance, hot‑set, ozone, mineral oil, low‑temperature and reaction‑to‑fire tests).

Applications and users

• Intended for fixed wiring or limited‑flex wiring in railway rolling stock (locomotives, passenger trains, trams, metro).
• Primary users: cable manufacturers, rolling stock OEMs, system integrators, procurement/specification engineers, testing laboratories and certification bodies, and installers seeking compliant high‑temperature, low‑smoke halogen‑free power cables.

Related standards

• EN 50382-1 (General requirements)
• EN 50305 (Test methods)
• EN 50355 / EN 50343 (selection, installation, current ratings)
• EN 60228 (conductors), EN 60332, EN 61034 (fire/smoke test methods)

EN 50382-2 is essential when specifying or certifying high‑temperature, fire‑resistant silicone insulated power cables for modern railway applications.
