Abstract

1 Scope

EN 50264‑3‑2 specifies requirements for, and constructions and dimensions of, multicore cables of the following types and voltage ratings:

• 300/500 V screened or unscreened (1 mm 2 , 1,5 mm 2 and 2,5 mm 2 , number of cores from 2 to 40);

• 0,6/1 kV screened or unscreened, (1,5 mm 2 to 50 mm 2 , 2, 3 and 4 cores).

NOTE Not all conductor sizes or number of cores are specified for every type.

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 50264‑3‑2 should be read in conjunction with Part 1 “ General requirements ”.
