Transmission tower

Structure used to support an overhead power line

A transmission tower (also known as an electricity pylon, hydro tower, or pylon) is a tall structure used to support an overhead power line. It is usually a lattice or tubular tower made of steel. In electrical grids, transmission towers carry high-voltage transmission lines that transport electric power from generating stations to electrical substations; while utility poles are used to support lower-voltage, electricity contactor relays, sub-station, sub-transmission lines or distribution lines that transport electricity from substations to electricity installed capacity to end customers.
