Transmission steel poles are another of the major types of transmission towers. They are made up of hollow steel poles. Tubular steel poles can be manufactured as one large piece, or as several small pieces which fit together. This type of pole often used in city power transmission grid, with little space, economic and lower cost.
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.
In general, this type of pole fabricated with mild steel or high strength steel, such as ASTM A36, ASTM A572 GR50, 65 or other.
MEGATRO Transmission Poles systems can accommodate a variety of cross-arm and other accessories. After fabrication 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.
MEGATRO fabricates every structure suspension Pole by solid steel legs and angle iron cross members & pipes. Structures can reach heights up to 200 meter. MEGATRO is one of the few manufactures who assemble a face of every tower section. This attention to quality may not be the cheapest process but it does insure every tower meets our high standards of quality. And it helps to reduce on-site construction cost due to mismatched assemblies.
After fabrication all suspension 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.
MEGATRO's suspension tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
