In the majority of locomotive connections, power is delivered to the train by an overhead electrical railway traction. In summary, energy is transferred to a locomotive by the current receiver, typically called a pantograph, which slips on contact cables hung to hanging lines. Hangs, in turn, are along a bearing line, which holds the weight of the whole system. Conductive parts of the network must be designed in such a way to on the one hand ensure delivery of the required quantity of electricity and, on the other hand, be able to carry the appropriate large mechanical stress necessary to achieve the required train speed. Copper and its alloys are the materials which best meet both conditions and are the most commonly used in the production for contact cables.
