330 kV Guyed Delta Suspension Transmission tower
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.  This type of tower is widely used for overseas client, and our MEGATRO design them and provide tower loading & geometry and other documents.

Our 330 kV Guyed Delta Suspension Transmission tower is designed and supported by guyed stay wire to reduce tower loading, and reduce space and rural land occupied. This tower belongs to suspension type, and OPGW on the top of tower.

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. 

Our MEGATRO had professional design engineer to provide every type of tower loading with detailed drawings for our client. The 330 kV Guyed Delta Suspension Transmission tower 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 330 kV Guyed Delta Suspension Transmission tower 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 330 kV Guyed Delta Suspension Transmission tower structure systems can accommodate a variety of cross-arm and other accessories. After fabrication330 kV Guyed Delta Suspension Transmission tower 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.
