Scope Anglisht

Part 2 of EN 50382 specifies requirements for, and constructions and dimensions of, single core cables of the following types and voltage ratings: – 1,8/3 kV unscreened, unsheathed with or without textile braid (1,5 mm² to 400 mm²); – 1,8/3 kV unscreened, sheathed (1,5 mm² to 400 mm²); – 3,6/6 kV unscreened, unsheathed with or without textile braid (2,5 mm² to 400 mm²); – 3,6/6 kV unscreened, sheathed (2,5 mm² to 400 mm²). All cables have class 5 or class 6 tinned or plain copper conductors to EN 60228, halogen-free insulation and where applicable 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 120 °C or 150 °C and a maximum temperature for short circuit conditions of either 250 °C or 350 °C based on a duration of 5 s. When the insulating compounds and sheath specified in this standard which are thermally capable of operating at 150 °C are used with tinned conductors, the maximum operating temperature is limited to 120 °C and, for the same technical reason, the maximum short circuit temperature is limited to 250 °C. The choice of sheath may also limit the maximum operating temperature to 120 °C. A textile braid may be included in the insulation or applied at its surface to unsheathed cables. 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. This Part 2 of EN 50382 should be used in conjunction with Part 1 “General requirements”.
