架空线路, 架空电缆
a wire or cable that is used to carry electricity or signals and is supported above the ground by poles or towers
An overhead line is a set of wires suspended above a railway track, used to supply electrical power to trains. These wires are connected to the train through a device called a pantograph, which collects electricity as the train moves. Overhead lines are commonly used in electric train systems, especially in areas where using a third rail is not possible. This system allows trains to run on electricity, reducing the need for fuel and helping to lower emissions while providing an efficient form of transportation.
