765KV POWER TRANSMISSION LINE STEEL TOWER
MEGATRO fabricates every structure from the ground up. Our power transmission line steel towers are constructed of 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. Till now Megatro can produce and take any power transmission line tower.
765KV power transmission line suspension tower belong to EHV tower, is widely use for longer distance power transmission, including 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 765KV power transmission line steel tower, and offers a variety of designs to meet client specific. Lattices of triangular cross-section or guyed type, and square lattices are also widely used. After fabrication all 765KV power transmission line 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 765KV tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
