500KV CRS towers

In power transmission line project, especially EHVAC and UHVAC project, some transmission line need to cross rive or mountain, these towers name cross-river towers. In our china, most of 500KV power transmission line tower often cross river, high mountain or building, the tower height more than 180 meters, overhand line span more than 500 meters.  

MEGATRO is professional manufacturer for 500KV CRS towers. We have skilled workers and design engineers with more than ten years design experiences, which can guarantee our quality solid as steel tower.

MEGATRO can optimized design and make pylon less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 500KV CRS towers, and offers a variety of designs to meet client specific. Lattices of triangular cross-section are most common, and square lattices are also widely used. After fabrication all 500KV CRS 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 

MEGATRO is one of the few manufactures who assemble a face of 500KV CRS towers. 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. MEGATRO 500KV CRS towers systems can accommodate a variety of cross-arm and other accessories. After fabrication 5500KV CRS 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. Even we take secondary finish for client again, which as duplex surface treatment.
