double circult transmission 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 the 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. 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 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.   

MEGATRO's double circuit transmission tower systems can accommodate a variety of cross-arm.  MEGATRO also offers a wide variety of accessories and mounts.
