Description

66KV DOUBLE CIRCUIT TRANSMISSION STEEL TOWER
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 provide 66KV double circuit and multi circuit transmission lines 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. 606KV double circuit transmission steel tower mainly supply to our foreign client, and we had supplied more than 600 tons to NGCP per year.
MEGATRO is one of the few manufactures who assemble a face of double circuit 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 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.
