Speeds like those of the Velaro® D high-speed trains from Siemens can only be reached because these trains no longer employ the motor in a locomotive. Instead the motor is positioned over the drive axes for acceleration. So the focus is no longer on just the locomotive, since the electronic systems and sub-systems are built into and distributed over the length of the entire train. A large variety of wide-area cable connections are required in order to reliably transmit signals throughout these systems.
One of these connections within the Velaro® Dis made by Weidmüller’s RockStar® HighPower connector. This product was specially developed for high-current applications involving motor power cables, eddy-current brakes and train carriage crossovers. The system is pluggable so that it is quick and easy to swap out components during maintenance work.
