500KV ANGLE TOWER
An electricity pylon or transmission tower is a tall structure,
usually a steel lattice tower, used to support overhead electricity
conductors for electric power transmission. They are used in high
voltage AC and DC systems as well as railway traction, and come in
a wide variety of shapes and sizes.
Transmission Tower structures can be classified by the way in which
they support the line conductors. Suspension structures support the
conductor vertically using suspension insulators...Strain
structures resist net tension in the conductors and the conductors
attach to the structure through strain insulators. Dead-end
structures support the full weight of the conductor and also all
the tension in it, and also use strain insulators.
Where the power transmission line must change direction, then angle
towers are used. Structures are classified as angle suspension,
angle strain, and angle dead-end.
MEGATRO fabricates every type of 500KV angle towers by solid steel
legs and angle iron cross members & pipes. Structures can reach
heights up to 200 meter. 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's angle towers systems can accommodate a variety of
cross-arm. MEGATRO also offers a wide variety of accessories and
mounts.
