BS EN 50264-3-1:2008

Railway applications. Railway rolling stock power and control cables having special fire performance. Cables with crosslinked elastomeric insulation with reduced dimensions. Single core cables | Status: Confirmed, Current

1 Scope EN 50264‑3‑1 specifies requirements for, and constructions and dimensions of, single core cables of the following types and voltage ratings: • 0,6/1kV 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”.
