450KV DC TOWER with lattice

450 kV Transmission towers

450KV tower similar to our Chinese 500KV tower, which mainly use in overseas markets; since 2004, MEGATRO has been manufacturing lattice transmission tower & tapered steel poles for utility applications. MEGATRO pioneered the development of transmission tower and design.

450KV have single circuit or double circuit with AC &DC type according to different power transmission line requirements. We also can design according to client design condition and other requirements

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 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.

MEGATRO fabricates every 450KV Transmission 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. After fabrication all 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.
