In an electric power transmission line, a suspension tower is where the conductors are simply suspended from the tower, the mechanical tension being the same on each side. In this case, the tower is supposed to carry a downward force, and a lateral force, but not a longitudinal force.
These may have, for each conductor, an insulator string hanging down from the tower, or two strings making a "V" shape. In either case, sometimes several insulator strings are used in parallel to give higher mechanical strength. These are used where a transmission line continues in a straight line, or turns through a small angle. In other cases, a tension tower (C or D Towers) is used.
220KV power transmission line tension tower is widely use for urban power gird and rural areas, which cross city building, road, river and any obstacles. MEGATRO can optimized design and make tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials.

MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of monopole for 220KV power transmission line suspension tower, and offers a variety of designs to meet client specific. Lattices of triangular cross-section are most common, and square lattices are also widely used. After fabrication all 220KV power transmission line  tension tower, are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.
