220KV Double circuit transmission line steel tower

Product Specification

220KV double circuit transmission tower

A double-circuit transmission line has two circuits. Usually both circuits operate at the same voltage. And in power transmission line, it must change direction, then steel angle deviation Towers are used. Structures are classified as angle suspension, angle strain, and angle dead-end. MEGATRO provide 220KV double circuit terminal tower mainly for our overseas client.

For time being our MEGATRO focus mainly international market and had export many kind of transmission structures to overseas clients. Since 2004, MEGATRO has been manufacturing lattice transmission tower & tapered steel poles for lighting, traffic control, 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.

MEGATRO is one of the few manufactures who assemble a face of 220KV double circuit transmission 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 220KV double circuit transmission 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' 500KV AC tension tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
