Megatro 110KV terminal transmission line steel tubular tower
Terminal tower is located at end of transmission line, which is also named anchor tower or anchor pylon, uses horizontal strain insulators and occur at the endpoints of conductors. Such endpoints are necessary when interfacing with other modes of power transmission and, due to the inflexibility of the conductors, when significantly altering the direction of the tower line. Terminal towers are also employed at branch points as branch pylons. A tower at which the power line runs further as overhead line and as underground cable is a branch tower for a cable branch.
This photo refer to our 110KV four circuit terminal tubular tower, which used in Chinese rural region transmission line project. Tower legs are steel pipes and bracing consisted of angle steel. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 110KV terminal towers, we have skilled worker with certificated welders, and offers design for our clients. In material we often adopt mild steel (ASTM A36, Q235B, ST37, BS40B), high strength and lower alloy (ASTM A572 GR50, GR65, Q345B, Q345C, Q420, Q460, S355J0, S355JR , ST52, BS50 and equivalent materials).
MEGATRO can optimized design and make transmission tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials. Our main design engineer from USA, can use PLS/TOWER software to design every type steel tower based on structural calculations and geometrical frame drawings. To meet the expectation, we produce shop drawings, components list and full production documentation, and even complete 3D models that facilitate the elimination of all design and drawings errors generated on the drawings. Another advantage is our 3D design and loading & design report, and can optimized the design and save cost for our clients.
After fabrication all 110KV terminal transmission 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
