Description

400KV double circuit transmission line steel tower is widely used in oversea market, especially in Indian, Arica and other countries market. Since 2008, we had design and supply every type of 400KV lattice steel transmission tower for our oversea clients.
A double-circuit transmission line has two circuits. For three-phase systems, each tower supports and insulates six conductors. Single phase AC-power lines as used for traction current have four conductors for two circuits. Usually both circuits operate at the same voltage. In HVDC systems typically two conductors are carried per line, but rarely only one pole of the system is carried on a set of towers.
Both tubular and lattice steel towers can be designed so as to support two circuits of electrical current. Double-circuit towers hold the different conductors stacked atop one another, while in single-circuit towers the conductors are lined up horizontally.
MEGATRO can optimized design and make tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of 400KV double circuit transmission line steel tower, and offers a variety of designs to meet client specific. Lattices of triangular cross-section are most common, and square lattices are also widely used. After fabrication all 400KV double circuit transmission line 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 towers.
