BS EN 50343 is a European standard that discusses rolling stock for railways. BS EN 50343 provides the best industry guidance on rules for the installation of cabling to minimize the hazards due to inefficient installation.
BS EN 50343 outlines the requirements for the installation of cabling on railway vehicles and within electrical enclosures on railway vehicles. And including magnetic levitation trains and trolleybuses.
BS EN 50343 covers cabling for making electrical connections between items of electrical equipment, including cables, busbars, terminals, and plug/socket devices. The material selection criteria given here apply to cables with copper conductors.
Concerning trolleybuses, BS EN 50343 applies to the whole electric traction system, including current collecting circuits, power converters, and the respective control circuits.
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.
BS EN 50343 applies in conjunction with the relevant product and installation standards. Stricter requirements than those given in BS EN 50343 may be necessary.
Note 1: BS EN 50343 does not cover special effect conductors like fiber optic cables or hollow conductors (waveguides).
Note 2: BS EN 50343 does not apply to the following:
BS EN 50343 on the installation of cabling for rolling stock is relevant to:
Rolling stock cables from part of a vast product range encompassing all cables used by moving vehicles across railways, metro, and underground rail infrastructures. These are used for power, control, communication, heating, and ventilation inside the vehicles.
Cable assembly consists of one or more cores (screened or unscreened), their covering(s), assembly protection, screen(s), and sheath.
BS EN 50343 guideline assists you with general requirements, selection of cable size for control cables, selection of cable size for cables for power distribution based on continuous load current, selection of cable size for cables for power distribution based on the rating of the protection device, cables for protective bonding, bending radii, other mechanical requirements, provision of spares, connections for return current and more for installation of cabling for rolling stock.
BS EN 50343 also provides EMC requirements, marking for identification, and testing for installation of cabling for rolling stock.
With compliance and obedience to BS EN 50343, you can get proper guidance on the installation of cabling for rolling stock that can minimize the occurrence of hazards.
