Remark: above technical data only references for our client, we can design every type for our overseas clients.
 
For urban power grid, even rural areas, 110KV 1B7-J1  SC tension and transmission power tower is widely used. Some adopt monopole, and some angular towers. MEGATRO have rich experience in successfully handling the demands of 110KV power transmission line angular tower, and MEGATRO fabricated angular tower by angle steel bar. Tower structures can reach heights up to 200 meter according to client requirements.

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 110KV power transmission line angular 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.

MEGATRO 110KV power transmission line angular Towers systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts...
