适用范围: 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 mm2, 1,5 mm2 and 2,5 mm2, number of cores from 2 to 40); • 0,6/1 kV screened or unscreened, (1,5 mm2 to 50 mm2, 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”.
