34、014 6 1 Scope This European Standard specifies requirements for the installation of cabling on railway vehicles and within electrical enclosures on railway vehicles, including magnetic levitation trains and trolley buses. NOTE With respect to trolley buses, this European Standard applies to the whol
35、e electric traction system, including current collecting circuits, power converters and the respective control circuits. The installation of other circuits is covered by street vehicle standards for example those for combustion driven buses. This European Standard covers cabling for making electrica
36、l connections between items of electrical equipment, including cables, busbars, terminals and plug/socket devices. It does not cover special effect conductors like fibre optic cables or hollow conductors (waveguides). The material selection criteria given here are applicable to cables with copper co
37、nductors. This European Standard is not applicable to the following: special purpose vehicles, such as track-laying machines, ballast cleaners and personnel carriers; vehicles used for entertainment on fairgrounds; vehicles used in mining; electric cars; funicular railways. As the field of cabling i
38、n rolling stock is also dealt with in the cable makers standard, references are made to EN 50264 series, EN 50306 series, EN 50382 series and EN 50355. This European Standard applies in conjunction with the relevant product and installation standards. Stricter requirements than those given in this E
39、uropean Standard may be necessary. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
