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.
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.
