230KV double circuit suspension towers
This photo refers to our 230KV double circuit suspension towers, which carry double circuit transmission project. A double-circuit transmission line has two circuits. Usually both circuits operate at the same voltage. MEGATRO is experienced in design transmission towers to support two circuits of electrical current. Double-circuit transmission and distribution towers hold the different conductors stacked atop one another, while in single-circuit towers the conductors are lined up horizontally. A suspension tower is where the conductors are simply suspended from the tower, the mechanical tension being the same on each side. In this case, the tower is supposed to carry a downward force, and a lateral force, but not a longitudinal force.
MEGATRO can optimize design, to set a compact, narrow base, the pole design not only advanced but practical, with an emphasis on economic rationality to ensure safe and reliable operation. Today, with over 10 years of experience and our commitment to excellence, MEGATRO remains an industry leader in the manufacture and design of steel tubular & monopole structures for all Highway, Municipal, Custom, telecom, lighting and electric Utility applications. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software. 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.
MEGATRO is one of the few manufactures who assemble a face of 230KV double circuit suspension 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 230KV double circuit suspension towers systems can accommodate a variety of cross-arm and other accessories. After fabrication all 230KV double circuit suspension 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.
