Product Description

Substation frameworks combine with tubular and angular structure support, being as high-voltage electric system facility for switch generators, equipment, and circuits or lines in and out of a system. It also is used to change AC voltages from one level to another, and/or change alternating current to direct current or direct current to alternating current. Some Substation frameworks are small with little more than a transformer and associated switches. Others are very large with several transformers and dozens of switches and other equipment.


MEGATRO mainly provide every type of substation framework, which is the steel framework for electric power transmission and transformation and widely used in power transmission &distribution industry. MEGATRO is equipped with sophisticated machinery, and welded workers and equipment for the manufacture of Substation frameworks, to ensure higher level quality. Before mast production, our engineer often take longer time communication with buyer engineer to discuss technical requirements and drawings, until final drawings confirmed, then we start order again.
In material, we adopt high strength steel such as ASTM A572 GR50, GR65, Q420, Q460, S355J0, S355J0, Fe510, ST52 or other equivalent steel to meet project requirements. MEGATRO can optimize design and make Substation frameworks solid, high strength, proper span distance, good wind resistance, and economy in the use of materials.
After fabrication all Substation frameworks, are delivered to the galvanizing facility to be Hot DIP Galvanized. Substation frameworks are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.
