køreledning

Køreledning, also known as a catenary, is a system of overhead wires used to supply electricity to electric trains, trams, and trolleybuses. The system consists of one or more wires suspended above the track or road, supported at intervals by poles or structures. The pantograph, a device mounted on the roof of the vehicle, makes contact with the køreledning to draw electrical power. This power is then used to drive the vehicle's electric motors. Køreledning systems are crucial for electric public transportation, enabling efficient and environmentally friendly operation by eliminating the need for on-board fuel storage. The design of køreledning systems varies depending on factors such as speed, weather conditions, and the type of vehicle being powered. Maintaining the correct tension and alignment of the wires is essential for reliable power transfer and to prevent the pantograph from losing contact. The term "køreledning" is Danish for "running wire" or "overhead line."
