Megatro 138KV typical guyed tubular suspension structure
Guyed towers are utilized to achieve the maximum in elevation and loading at an economical cost. The addition of heavier braced sections and torque arm guy points allow a tower to be engineered custom to its loading specifications. Guyed tower can withstand high tension or wind loading during power transmission lines. This tubular suspension structure was made of hollow pipe, These poles can be quickly deployed with minimal hardware and labor, factory drilled to customer specifications or modified in the field, if required, using a carbide-tip bit. In general, this type of pole fabricated with mild steel or high strength steel, such as ASTM A36, ASTM A572 GR50, GR65, Q235B, Q345B, S355JO, S355JR, ST37, ST52, BS 50B or other.
Our 138KV typical guyed tubular suspension structure with some type as follow:
(1) Flange connection
(2) Slip joint
(2) Step type
(3) Stagger type
(4) Others
Pole foundation types have:
Direct embedment
Anchor bolt
Based plate
Vibratory steel caisson
MEGATRO provide Series 138KV typical guyed tubular suspension structure at a much lower material cost than self supporting towers due to the efficient use of steel guy lines, The guyed lattice masts are normally guyed in three directions equally spaced 120 degrees apart over an anchor radius of typically 2/3 of the tower height or as per client special requirements.
Since 2004, MEGATRO has been manufacturing every type of lattice transmission tower & tapered steel poles for 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. 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 138KV typical guyed tubular suspension structure. 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 138KV typical guyed tubular suspension structure systems can accommodate a variety of cross-arm and other accessories. After fabrication 138KV typical guyed tubular suspension structures 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.
