230KV Four circuits transmission line tower
Four-circuit transmission line has four circuits. For three-phase systems, each tower supports and insulates twelve conductors. Usually four circuits operate at the same voltage and at top of tower are OPGW. Tension tower was located between every three or four suspension tower to pull the conductors which are re-tied in tension tower insulators.

This photo refer to our 230KV four circuits tower for Indonesia client. Tower stubs are large size angle steel and bracing consisted of small size angle steel. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 230KV four circuit transmission 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 230KV four circuits 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
