overhead lines
Power cables above
Overhead lines are electrical cables suspended above ground on poles or towers, carrying power or telecommunications signals across distances.
The term distinguishes these from underground cables: The storm brought down several overhead lines.
In transportation, overhead lines supply electricity to trains and trams through contact with a pantograph mounted on the vehicle's roof.
