overhead line
Elevated power wire
An overhead line is a cable suspended above ground on poles or towers, typically carrying electrical power or supporting transit systems.
Power lines running along streets are overhead lines, as are the wires that supply electricity to trams and trolleybuses.
The train drew power from the overhead line.
