In power transmission line project, where the conductors are straight, a tangent tower is used. Tower structures are classified as tangent suspension and tangent strain. In a double circuit transmission line, tangent suspension and tangent strain tower often used. For suspension tower, the conductors are simply suspended from the tower, in this case, the tower is supposed to carry a downward force, and a lateral force, but not a longitudinal force. These may have, for each conductor, an insulator string hanging down from the tower, or two strings making a "V" shape. In either case, sometimes several insulator strings are used in parallel to give higher mechanical strength. These are used where a transmission line continues in a straight line, or turns through a small angle. In other cases, a tension tower (C or D Towers) is used. For tangent strain tower, the tower resists net tension from conduction which use strain insulator.
For a double-circuit transmission line, which has two circuits, both tubular and lattice steel towers can be designed so as to support two circuits of electrical current. Double-circuit tangent transmission towers hold the different conductors stacked atop one another, while in single-circuit towers the conductors are lined up horizontally.
MEGATRO provide the double circuit tangent transmission lines tower for our esteemed clients. The Tower Line work involves Survey, check survey, and span calculations essential for tower extensions. Moreover, Tower designs and prototype approval is done. The towers are for 35KV, 66KV, 110 KV, 132 KV, 220 KV, 400 KV, 500KV, 750KV, and 800KV.
MEGATRO is one of the few manufactures who assemble a face of double circuit tangent transmission 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.
After fabrication all double circuit tangent transmission 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 double circuit transmission tower systems can accommodate a variety of cross-arm. MEGATRO also offers a wide variety of accessories and mounts.
