Qingdao Megatro industry company |
MEGATRO provide 138KV angle tower for overseas clients since 2006.
They are used in high voltage AC and DC power transmission line
systems as well as railway traction, and come in a wide variety of
shapes and sizes. Where in the power transmission and distribution
line, it must change direction, then angle towers are used.
Structures are classified as angle suspension, angle strain, and
angle dead-end.
MEGATRO fabricates this 138KV angle towers by solid steel legs and
angle iron cross members & pipes. Structures can reach heights
up to 200 meter, even higher as per client requirements. MEGATRO is
one of the few manufactures who assemble a face of every tower
section. 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 angle 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.
MEGATRO angle towers systems can accommodate a variety of
cross-arm. MEGATRO also offers a wide variety of accessories and
mounts.
