Product description
345KV overhead transmission line steel tower
MEGATRO provide 345KV overhead transmission line steel tower for overseas
clients. This overhead power line is a structure used in electric power
transmission and distribution to transmit electrical energy along large
distances. It consists of one or more conductor (most often three or four)
suspended by towers or utility poles. Since most of the insulations is provided
by air, overhead power lines are generally the lowest-cost method of power
transmission for large quantities of electric energy.
Towers for support of the lines are made of wood (as-grown or laminated), steel
(either lattice structures or tubular poles), concrete, aluminum, and
occasionally reinforced plastics. MEGATRO mainly produce, design and install
galvanized steel tower, and provide service on site for 345KV overhead
transmission line.
345KV power transmission line belongs to high voltage grade, used for
sub-transmission and transmission of bulk quantities of electric power and
connection to very large consumers. Our 345KV overhead transmission line steel
tower including many types, such as lattice angular tower, tubular tower,
monopole, or guyed towers and mast.
MEGATRO is one of the few manufactures who assemble a face of 345KV overhead
transmission line steel 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 345KV overhead 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.
MEGATRO 345KV overhead transmission line steel tower systems can accommodate a
variety of cross-arm. MEGATRO also offers a wide variety of accessories and
mounts.
