For the majority of transport connections, the power supply for a train moving along a track is provided by overhead lines. In short, the energy is transferred to the locomotive by way of a pantograph that slides over the contact wire suspended under the catenary line on droppers. The droppers in turn are strung along the catenary line that supports the weight of the entire system. The conductive components of the network must be designed in such a way, so as to ensure the provision of the required amounts of electricity on the one hand, and on the other hand, they must be able to carry appropriately high mechanical tension necessary for the achievement of the required train speeds. The materials that best conform to both these conditions and are most commonly used for the production of wires for the overhead lines are traditionally copper and its alloys.
