DESCRIPTION

BS EN 50264-2-1:2008


This standard BS EN 50264-2-1:2008 Railway applications. Railway rolling stock power and control cables having special fire performance is classified in these ICS categories:
  • 29.060.20 Cables
  • 13.220.20 Fire protection
  • 45.060.01 Railway rolling stock in general

EN 50264-2-1 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 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 50264-2-1 should be read in conjunction with Part 1 “General requirements”.
