Power towers, also known as transmission line towers, are generally categorized by shape into five types: cup-shaped, cat's head-shaped, uppercase letter-shaped, cross-shaped, and drum-shaped. By application, they are categorized as follows:

Available: Tension Towers, Straight Towers, Corner Towers, Position Exchange Towers ( Towers for changing conductor phase positions), Terminal Towers, and Spanning Towers, etc., with their structural characteristics being:

All tower types are of space truss structures, the members of which are mainly composed of single equal-angle steel bars or combined angle steels, with materials generally using Q235 (A3F) and

Q345 (16Mn) in two types, the connection between the rods is made using coarse bolts, connected by shear force on the bolts; the entire tower is composed of angle steel, connecting steel plates, and bolt sets.

Individual components such as the tower base are welded from several steel plates to form a composite part, making hot-dip galvanizing for corrosion protection, transportation, and construction installation extremely convenient.
