Power Transmission Tower

A transmission tower is a structure set up for the purpose of transmitting and receiving power, radio, telecommunication, electrical, .Transmission towers support the high-voltage conductors of overhead power lines, from the generating station switchyard right up to the source substations and satellite substations located near populated areas. Their shape, height and sturdiness (mechanical strength) depend on the stresses to which they are exposed.There are four major categories of transmission towers: suspension, terminal, tension, and transposition. Some transmission towers combine these basic functions. Transmission towers and their overhead power lines are often considered to be a form of visual pollution.Three tower types: Towers are usually classified into three categories: guyed or cable-supported, free-standing or self-standing, and monopole. The self-supporting and monopole towers are similar in that neither requires guy wires or any other support structure.The peak of the tower(the portion above the top cross arm) The cross arm (Cross arms of the transmission tower hold the transmission conductor) Cage of transmission tower(portion between tower body and the peak is known as a cage of transmission tower)
