Information regarding selection and installation of cables, including current ratings can be found in EN 50355 and EN 50343. The procedure for selection of conductor cross-sectional area, including reduction factors for ambie
18、nt temperature and installation type, is described in EN 50343. NOTE Current ratings for inclusion in EN 50355 are under development for the next amendment. Part 1, General requirements, contains a more extensive introduction to EN 50382, and should be read in conjunction with this Part 2. BS EN 503
19、82-2:2008 5 EN 50382-2:2008 1 Scope 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 mm to 400 mm); 1,8/3 kV unscreened, sheathed (1,5
20、mm to 400 mm); 3,6/6 kV unscreened, unsheathed with or without textile braid (2,5 mm to 400 mm); 3,6/6 kV unscreened, sheathed (2,5 mm to 400 mm). 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
21、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 d
22、uration 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 li
23、mited 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 permiss
24、ible 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”. 2 Normative references The following referenced documents are indispensable for the application of this document.
