Transmission Tower

The transmission towers have done their work quite efficiently.

Transmission towers are constructed objects that are used to keep electricity lines stable and safe above the ground.
‘Transmission towers’ are also known as ‘electricity pylons’, and in some circumstances they are called ‘hydro towers’.
Transmission towers are typically erect off the ground, and stand between 15 to 55 metres (49 to 180 ft) in height, although some can reach heights of 370 metres (1214 feet).
Transmission towers generally transmit electricity voltages from 66 to 230 kilovolts, and different towers are needed for different voltages.
Typically, wires are carried through transmission towers and are insulated with ceramic, glass, or other materials; while three or more wires can generally be held on the tower at one time.

Transmission towers are generally built with a lattice-work structure and are most often made of metal, but concrete, wood, and other materials can also be used; and the towers usually include a lightening rod that directs any lightning-caused energy towards the ground.
Transmission towers are often marked with a notice that notes certain properties and the identification number of the specified tower; and some towers also have lights, that are used to signify their location during nighttime.
As at 2014, the tallest transmission towers in the world were 370 metres (1214 feet) high, found in Asia, on China’s Damao and Liangmao Islands, however there is a taller tower planned for a site on Indonesia’s island of Bali, that is proposed to reach 376 metres (1234 feet) in height.
Transmission towers can be constructed in position, or on the ground, and put in place using air or land based cranes.
Scenic views can be disrupted by the presence of transmission towers, and this is classified as visual pollution; while drops in land or house values can occur as a result.
