220KV OHL STEEL TOWER

220KV OHL steel tower refer to a lattice steel structure used in overhead electric power transmission and distribution to transmit 220KV circuit electrical energy along large distances. It consists of one or more conductor (most often three or four) suspended by towers or utility poles. Since most of the insulations is provided by air, overhead power lines are generally the lowest-cost method of power transmission for large quantities of electric energy.
Towers for support of the lines are made of wood (as-grown or laminated), steel (either lattice structures or tubular poles), concrete, aluminum, and occasionally reinforced plastics. MEGATRO mainly produce, design and install galvanized steel tower, and provide service on site for 220KV overhead transmission line.
220KV power transmission line belongs to high voltage grade, used for sub-transmission and transmission of bulk quantities of electric power and connection to very large consumers. Our 220KV overhead transmission line steel tower including many types, such as lattice angular tower, tubular tower, monopole, or guyed towers and mast.

MEGATRO had professional QA &QC team to control quality and execute strict QC & QC plan as per client requirements. MEGATRO is one of the few manufactures who assemble a face of 220KV overhead transmission line steel 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 overhead transmission line steel 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 220KV overhead transmission line steel tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
