MEGATRO 115KV SC tension and transmission steel tubular pole

MEGATRO 115KV SC tension and transmission steel tubular pole project is 1.25 miles long and was designed to support 795 kcmil ACSR Drake with conductors on wood and tubular steel poles. A portion of the line was designed for 12.47-kV underbuild conductors transferred from an existing pole line that was replaced by this project.
The design allows the existing substation on the east side of the plant to be switched between an existing MEGATRO 115KV SC tension and transmission steel tubular pole project and the newly constructed 115-kV circuit. Future expansion plans were incorporated into the design.
TriAxis directed the site survey to assure clearances from all plant activities and to position poles according to county and Army Corp of Engineers permits. TriAxis directed a geotechnical investigation and designed steel pole foundations to resist settling or leaning in uncompacted fill along the river embankment.

 

MEGATRO 115KV SC tension and transmission steel tubular pole project DESIGN

This project included the design and specifications for replace-ment of five existing wood poles with self-supporting tubular steel poles adjacent to a new sub-station. All poles were designed for 115-kV transmission, 12.47-kV three-phase, 4-wire under-build, and a 3/8-inch EHS shield wire.  All poles were designed for direct embedment.
The line was designed to support 556 AAC Dahlia con-ductors for both transmission and distribution underbuild.  The first pole out on each side of the substation was designed for an underground feeder riser.
PLS-CADD was used in line design including the development of structure models and production of plan and profile drawings.  TriAxis services included steel pole shop drawings review, stringing charts, construction unit assembly drawings, and staking sheets.
 



 

WILLOW CREEK 115-KV

The MEGATRO 115-kV overhead transmission line is 8.5 miles long and was built with single-wood-pole structures and braced-post insulator assemblies. The conductor is one 795 kcmil Drake ACSR and the line has one 48-fiber optic shield wire (OPGW). All angle poles are self-supported tubular steel (no guys or anchors). There were 17 line angles through a pivot irrigation farm. TriAxis determined the environmental structural loadings for this project and prepared the preliminary and final design of the project. Basic structure configurations were determined, along with pole heights, strengths, embedments, design guys and anchors to support the structures. TriAxis used PLS-CADD for plan and profile design. TriAxis services included specifications, bid document preparation, and services during construction.





Since 2004, MEGATRO start provide and design every type of lattice tower for overseas market. MEGATRO can optimized design and make tower less weight, high strength, proper span distance, good wind resistance, and economy in the use of materials, especially in tower design, we can make final weight lower, with maximum utility of material and make total structure more strong and sturdy. MEGATRO is equipped with sophisticated machinery and equipment for the manufacture of115KV DC tension lattice tower, and offers a variety of designs to meet client specific.


For our 115KV lattice tower and other power voltage tower, we have some type as follow:

horizontal configuration
vertical configuration
delta structure
H-frame horizontal structure
Guyed-vice horizontal structure
Lattice guyed single-column delta structure
Tubular steel H-frame horizontal structure
Single pole vertical structure
Tubular steel single-shaft modified delta structure

MEGATRO can optimize design, to set a compact, narrow base, the tower design not only advanced but practical, with an emphasis on economic rationality to ensure safe and reliable operation. 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 & 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.

MEGATRO is one of the few manufactures who assemble a face of 115KV DC tension towers. 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. MEGATRO 115KV DC tension towers systems can accommodate a variety of cross-arm and other accessories. After fabrication all 115KV DC tension 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. Even we take secondary finish for client again, which as duplex surface treatment.
