Railway applications. Railway rolling stock power and control cables having special fire performance -- 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 90Β° C and a maximum temperature for short circuit conditions of 200 Β°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 βGeneral requirementsβ.
