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.

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.

34、ilicone insulated cables shall be as follows: a) unsheathed: 1,8/3 kV; 3,6/6 kV; b) sheathed: 1,8/3 kV; 3,6/6 kV. 5 Marking and identification 5.1 Marking of cable Cables shall be marked with the following: indication of origin; EN reference; voltage rating (Uo); number of conductors and their size;
35、 a code designation according to Annex A; conductor temperature. An example of a complete mark for a sheathed cable is: * EN50382-2 3600V 1x400 OF 150C The marking shall conform to the requirements of EN 50382-1, Clause 5. BS EN 50382-2:2008 7 EN 50382-2:2008 NOTE Other markings (e.g. batch number,
36、year of manufacture) may be added upon agreement between manufacturer and user. 5.2 Colour identification 5.2.1 Insulation The insulation of unsheathed cables shall be black and that of sheathed cables white or neutral unless otherwise agreed between the manufacturer and purchaser. If a colour other
37、 than white or neutral is specified it shall be a colour in accordance with HD 308. The colour shall be clearly identifiable and durable. Durability shall be checked by the test given in EN 50305, 10.1. Conformity with these requirements shall be verified by visual examination. 5.2.2 Sheath The shea
38、th shall be black unless otherwise agreed between the manufacturer and purchaser. 6 Construction of cables 6.1 General The cable shall conform to the applicable general requirements given in EN 50382-1, and to the specific requirements of this part. Conformity with the requirements shall be checked
39、by inspection and by the tests given in Table 7. The cable dimensions shall be as given in Tables 1 to 5 as appropriate to the cable type. 6.2 Conductor For cables rated at 120 C conductors shall be tinned annealed copper, class 5 or class 6, according to EN 60228. For cables rated at 150 C conducto

When tested in accordance with EN 10002-1 the minimum average elongation of wires from the conductor shall be 15 %, with a minimum value of 10 % for an individual wire. NOTE It is not necessary to test all individual wires
41、. 5 % of wires or 10 wires, whichever is the fewer, should be selected at random. 6.3 Conductor screening For cables in Tables 3 to 5 it is permitted to use a conductor screen. When used it shall be as given in EN 50382-1, 6.1.6. 6.4 Separator It is permitted to place a non-hygroscopic separator tap
42、e of coloured material between the conductor and insulation if the cable construction does not include a conductor screen. If used, the separator tape shall be easily removable from the conductor. A separator may be included between the insulation and sheath. BS EN 50382-2:2008 EN 50382-2:2008 8 6.5
43、 Insulation system The insulation shall be one or more closely adherent layers of extruded material as defined in EN 50382-1, applied so as to meet the requirements of compound Type EI 111 or EI 112. a) for unsheathed cables: - Type EI 111: extra low temperature resistant, oil resistant; b) for shea
44、thed cables: - Type EI 111: extra low temperature resistant, oil resistant; - Type EI 112: extra low temperature resistant, non oil resistant. The insulation shall be applied to meet the requirements of EN 50382-1, 6.2. The insulation thickness shall conform to the specified value given in Tables 1

46、tra low temperature resistant, oil resistant. If sheathing compounds EM 105 or EM 106 are used, the cable is rated at 120 C. If sheathing compound EM 107 is used, the cable is rated at 150 C. The sheath shall consist of one or more closely adherent layers of the same type. The sheath shall be applie
47、d to meet the requirements of EN 50382-1, 6.4. The sheath thickness shall conform to the specified value given in Tables 2 and 5. 6.7 Textile braid It is permitted to include a textile braid, either within the insulation or at its surface. When a textile braid is included in the construction of a ca
48、ble, it shall consist of material compatible with the operating temperature (for example braid made of glass filaments shall be treated with a suitable substance in order to avoid fraying). When a braid is applied to the surface of the insulation a separator may be included between the insulation an
49、d braid. NOTE A braid may be included in the construction at the request of a customer.
