Description / Abstract:

This International Standard specifies the main characteristics of the supply voltages of traction systems, such as traction fixed installations, including auxiliary devices fed by the contact line, and rolling stock, for use in the following applications:

– railways;

– guided mass transport systems such as tramways, light trains, elevated and underground railways and trolleybus systems;

– rail bound material transportation systems, e.g for coal or iron-ore.

This standard is also applicable for low speed maglev trains or linear motor transport systems.

This standard does not apply to:

– mine traction systems in underground mines;

– cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) insofar as these are not supplied directly or via transformers from the contact line system and are not endangered by the traction power supply system;

– suspended cable cars;

– funicular railways.

This standard deals with long term overvoltages as shown in Annex A.
