Suspension angle towers are built when it is necessary for the route of the electrical current to turn. These angle towers are usually designed so that the axis of the cross-arm bisects the angle of the conductors. This is the most efficient way to use the tower. 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. Here we named these towers as V-type suspension towers.
MEGATRO can optimized design and make tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials. We offer comprehensive solutions to match the special requirements of each organization, aiming for absolute customer satisfaction. All our V-type suspension towers are marked by quality construction and superior strength, and are suitable for a wide range of demanding applications in power transmission infrastructure.
MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of V-type suspension towers, and offers a variety of designs to meet client specific. Our V-type suspension tower is fabricated by angle steel bar or solid steel pipe with angle or bracing members, which provides great strength, low weight and wind resistance, and economy in the use of materials. After fabrication all V-type suspension towers, 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.
