Detailed Description

220KV crossing railway tower Railway safety is a crucial aspect of rail operation the world over. However, sometimes power transmission line system seems conflict with railway transport layout. Especially at railway or road, overhead transmission lines are necessary for power transmission and distribution. The main supporting unit of overhead transmission line is transmission tower. Cross-railway transmission towers have to carry the heavy transmission conductor at a sufficient safe height from ground. In addition to that all towers have to sustain all kinds of natural calamities. So transmission tower designing is an important engineering job where all three basic engineering concepts, civil, mechanical and electrical engineering concepts are equally applicable. Here the 220KV crossing railway tower is widely used in overseas and Chinese market. MEGATRO is one of the few manufactures who assemble a face of every 220KV crossing railway 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. MEGATRO had professional QA &QC team to control quality and execute strict QC & QC plan as per client requirements. After fabrication all 220KV crossing railway 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 crossing railway tower for power transmission systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
