500KV Gantry Single circuit overhead transmission tower
A single-circuit transmission line carries conductors for only one
circuit. For a three-phase system, this implies that each tower
supports three conductors. In single-circuit towers the conductors
are lined up horizontally. Both tubular and lattice steel towers
can be designed so as to support single-circuit of electrical
current. Single-circuit towers hold the different conductors
stacked atop one another, and the power transmission line direction
maybe changed due to requirements, which have light angle, medium
angle, and heavy angle.
This photo refers to our 500KV gantry single circuit overhead transmission tower. Due to tower loading, wind speed and other design requirements, sometimes the gantry steel structure will be used for power transmission line. This tower adopt bundle insulator and four split conductors; on top of tower peak is OPGW. Moreover, this tower design need less land occupied, but tower loading must be considered well.
Our MEGATRO provide and design this type 500KV Single circuit tower
mainly for our overseas client. Since 2004, MEGATRO focus mainly
international market and had export many kind of transmission
structures to overseas clients. MEGATRO has been manufacturing
lattice transmission tower & tapered steel poles for lighting,
traffic control, communication and utility applications. MEGATRO
pioneered the development of transmission tower, telecom tower,
substation, and other steel structure and was also at the forefront
in the design of Transmission tower.
Today, with over 10 years of experience and our commitment to
excellence, MEGATRO remains an industry leader in the manufacture
and design of steel tubular & angular & monopole structures
for all Highway, Municipal, Custom, telecom, lighting and electric
Utility applications. MEGATRO has a complete staff of professional
engineering personnel trained in the PLS Pole program and three
different manufacturing processes for producing steel towers, poles
and other supports. We utilize the latest versions of PLS-CADD,
PLS-POLE, TOWER, AutoCAD and other CAD software.
The structure shall be designed according to load combinations
given as per IEC 61936-1 and as illustrated below:
Normal loads
1 Dead weight load
2 Tension load
3 Erection load
4 wind load
Exceptional loads
1 Switching forces
2 short-circuit forces
3 Loss of conductor tension
4 Earthquake forces
MEGATRO is one of the few manufactures who assemble a face of 500KV
Gantry Single circuit overhead 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 500KV Gantry Single circuit overhead transmission
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' 500KV Gantry
Single circuit overhead transmission tower systems can accommodate
a variety of cross-arm. MEGATRO also offers a wide variety of
accessories and mounts.
