Abstract
Bar composed of an aluminum section with which copper contact jumpers are brought into intimate contact at the end or at regular intervals. The flanges of jumpers 20 have silver plated areas A on their internal surface, for example in the form of strips 24 transverse to the length of the bar and silver plated areas B on their external surface located between the areas A and the web of the jumper. The internal silver plated areas contribute to welding the jumper to the section and the external areas are used for making contact with junction devices or fish plates.
