Railway applications - Rolling stock - Rules for installation of cabling
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 whole 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 electrical 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 conductors. 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 in 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 European Standard may be necessary.

Železniške naprave - Vozna sredstva - Pravila za inštaliranje kablov
EN 50343 določa zahteve za inštaliranje kablov na železniških vozilih in v električnih ohišjih na železniških vozilih, vključno z vlaki na magnetni blazini in trolejbusi. Ta evropski standard zajema kable za ustvarjanje električnih vezav med predmeti električne opreme, vključno s kabli, zbiralčnimi vodili, terminali in napravami z vtičem/vtičnico. Ne vključuje vodnikov za posebne učinke, kot so kabli optičnih vlaken ali votli vodniki (valovodi). Kriteriji za izbiro materiala v tem standardu veljajo za kable z bakrenimi vodniki. Ta evropski standard se ne uporablja za: - vozila za posebne namene, kot so stroji za polaganje tirnic, odstranjevalci balasta in vozila za prevoz osebja; - vozila za zabavo na sejmih; - vozila za uporabo v rudnikih; električna vozila; - vzpenjače. Ker kable v voznih sredstvih obravnava tudi standard za proizvajalce kablov, standard navaja serije EN 50264, EN 50306, EN 50382 in EN 50355. Ta evropski standard se uporablja v povezavi z ustreznim izdelkom in standardi namestitve. Morda so potrebne strožje zahteve od zahtev iz tega evropskega standarda.
