SIST EN 50382-2:2008/A1:2013

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".

2. del standarda EN 50382 določa zahteve ter konstrukcije in dimenzije enojedrnih kablov naslednjih vrst in nazivnih napetosti: – 1,8/3 kV nezaslonjeni, neoklopljeni s tekstilnim opletom ali brez (1,5 mm² do 400 mm²); – 1,8/3 kV nezaslonjeni, oklopljeni (1,5 mm² do 400 mm²); – 3,6/6 kV nezaslonjeni, neoklopljeni s tekstilnim opletom ali brez (2,5 mm² do 400 mm²); – 3,6/6 kV nezaslonjeni, oklopljeni (2,5 mm² do 400 mm²). Vsi kabli imajo pokositrene ali navadne bakrene vodnike razreda 5 ali 6 za EN 60228, nehalogensko izolacijo in, kjer je ustrezno, nehalogenski oklop. Uporabljajo se pri železniških vozilih kot fiksno ožičenje ali ožičenje, kjer je upogibanje pri delovanju omejeno. Zahtevana je enakomerna temperatura vodnika, ki ne presega 120 °C ali 150 °C ter največja temperatura za kratkostične pogoje 250 °C ali 350 °C za trajanje 5 sekund. Ko se izolacijske spojine in oklop, določeni v tem standardu, ki so zmožni delovati pri 150 °C, uporabljajo s pokositrenimi vodniki, je največja obratovalna temperatura omejena na 120 °C in iz enakega tehničnega razloga je največja kratkostična temperatura omejena na 250 °C. Tudi izbira oklepa lahko omeji obratovalno temperaturo na 120 °C. V izolacijo je lahko vključen tekstilni oplet ali se uporabi na površini neoklopljenih kablov. Pri pogojih za razvoj požara imajo kabli posebne lastnosti, kar zadeva največje dovoljeno širjenje plamena ter največjo dovoljeno emisijo dima in strupenih plinov. Ta 2. del standarda EN 50382 se uporablja skupaj s 1. delom »Splošne zahteve«.

Overview

The SIST EN 50382-2:2008/A1:2013 standard, published by CLC (European Committee for Electrotechnical Standardization), specifies requirements for railway rolling stock high temperature power cables with specialized fire performance. This Part 2 of the series focuses on single core silicone rubber insulated cables rated for continuous operation at temperatures of 120 °C or 150 °C. These cables are engineered for reliable performance in demanding railway environments where fire safety and high thermal resistance are critical.

This amendment (A1) updates the original 2008 standard to clarify temperature ratings and compliance details, effective for implementation from April 2014. The standard ensures consistent safety, quality, and interoperability of cables used in railway applications across European member states.

Key Topics

• Scope of Application
  Covers single core silicone rubber insulated power cables used in railway rolling stock that require enhanced fire resistance and high temperature operation (up to 120 °C by default, extendable to 150 °C by agreement).

• Temperature Ratings
  Standard specifies cables designed for continuous operating temperatures of either 120 °C or 150 °C, with provisions for tinned conductors to reach higher temperature limits through purchaser-manufacturer agreement.

• Fire Performance
  Emphasizes “special fire performance” to limit fire propagation, crucial for safety in railway vehicles.

• Material Specifications
  Details use of silicone rubber for insulation to withstand elevated temperatures while maintaining electrical and mechanical integrity.

• Compliance and Implementation
  Outlines national adoption deadlines and withdrawal of conflicting standards. Includes reference to patent considerations related to cable technologies.

• Multilingual and Multi-National Applicability
  Documents are available in English, French, and German, with scope covering all CENELEC member countries for standardized use.
