The electronic distribution panels (AC & DC panel) for the SSL project of Bombardier for transport for London have been developed in close cooperation with Bombardier. Bombardier Transportation provided the schematics and space limitations. Mors Smitt provided a creative solution.
Especially for this project a smart mechanical construction was developed resulting in easy assembly in the trains. In addition Mors Smitt was very closely involved with the integration of the solution to optimise the performance of the panel. A tilting panel was designed to place beneath a seat on the train.
This way the available space as well as the operating possibilities are combined without making concessions to the maintainability of the panel.
Bombardier selected a construction where the earth leakage module is combined with a circuit breaker to guarantee the optimum user safety. The MCB panels are connected to the train wiring with connectors. The installation of the panels was simple and fast, plug & play. The MCB panels were 100% tested before delivery. Delivery per trainset was ‘just in time’ according to Bombardier planning.
