Megatro 500kV Guyed "Delta" structure
The "delta" head assembly is installed to produce a supporting structure that extends up and out from the MID-point of the base. When installed, the structure angles outward, and creates a triangular shape that exhibits the structure's more colloquial name, "cat's head. It is one main type steel lattice power tower for high voltage AC and DC power transmission line systems. Sometimes, in order to withstand the strong loading or wind speed, we need design guyed delta 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.
MEGATRO provide Series 500 kV Guyed "Delta" 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, The mast construction consists of triangular lattice modular section, each module fully welded tubular leg and solid round bar bracing incorporating integral step rungs fabricated into the lattice framework on one face this removes the need for a separate ladder. All masts sections are hot dipped galvanized after fabrication. Mast heights range 9 up to 50 meters, these masts can also be Etched primed and powder coated as an optional extra if required
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 500 kV Guyed "Delta" 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 500 kV Guyed "Delta" structure systems can accommodate a variety of cross-arm and other accessories. After fabrication 500 kV Guyed "Delta" structure 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.
