In majority of locomotor connections, power of a trainset moving on tracks is carried out by an overhead electrical railway traction. To put it briefly, energy is transferred to a locomotive by the current receiver, popularly called a pantograph, which slips on contact cables hung to hanging lines. Hangs, in turn, are along the supporting 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, they must be able to carry the appropriate large mechanical stress, necessary to achieve the required train speed. Cooper and its alloys are the materials which the best meet both conditions and are the most commonly used in the production for contact cables.
