Product Description

MEGATRO 500KV SINGLE CIRCUIT TUBULAR STEEL TOWER

Transmission structures are one of the most visible elements of the electric transmission system. They support the conductors used to transport electric power from generation sources to customer load, typically between 110 kV and 765 kV (115, 000 volts and 765, 000 volts).
There are many different designs for transmission structures. Tubular steel poles are widely used in power transmission & distribution project. Tubular Steel Poles (TSP) are hollow steel poles fabricated either as one piece or as several pieces fitted together.


TSPs can be designed to carry either one or two electrical circuits, referred to as single-circuit and double circuit structures. Single-circuit structures typically hold the conductors horizontally. A single-circuit Alternating Current (AC) transmission line has three phases. MEGATRO is the professional manufacturer to provide every type of 500KV single circuit TSP. 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 of 500KV single circuit TSP, and offers a variety of designs to meet client specific.
After fabrication all 500KV single circuit tubular steel poles, are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are proce
sed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.
MEGATRO is one of the few manufactures who assemble a face of every tower section. 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.
