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. We manufacture them with complicated technology and adopted sophisticated production line. Now we sell them widely all over the world.
Substation is a high-voltage electric system facility. It is used to
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 substations 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.
