230KV DC and 500KV SC Tangent lattice tower
This photo refer to our 230KV DC and 500KV SC Tangent lattice tower, which bring two different power voltage transmission line but run parallel together. Both 230KV and 500KV belong to horizontal configuration tangent lattice steel structures. Only 230KV designed double circuit lines, whereas 500KV single circuit lines.
Due to wind speed and tower loading, we adopt ASTM A572 GR65 for these tower production, especially our engineer consider many factors in design. Since 2004, MEGATRO focus mainly international market and had export many kind of transmission structures to overseas clients. MEGATRO has been manufacturing lattice transmission tower & tapered steel poles for lighting, traffic control, tele-communication and utility applications. MEGATRO pioneered the development of transmission tower, telecom tower, substation, and other steel structure and was also at the forefront in the design of Transmission tower.
Today, with over 10 years of experience and our commitment to excellence, MEGATRO remains an industry leader in the manufacture and design of steel tubular & angular & monopole structures for all Highway, Municipal, Custom, telecom, lighting and electric Utility applications. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software.
Moreover, MEGATRO is one of the few manufactures who assemble a face of 230KV DC and 500KV SC Tangent lattice tower. 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 230KV DC and 500KV SC Tangent lattice 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' 230KV DC and 500KV SC Tangent lattice tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
