Transmission towers
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.
How are transmission towers built?
Structure Construction
Structures are assembled in sections near the new tower location and a crane is used to lift the sections into place. Crews then bolt the sections together. TSPs are either completely assembled near the tower location and then erected at once, or are assembled in sections.
