37.5 meters long, 14.5 meters high, 12 meters wide, and weighing 909 metric tons when in operation.Those are the vital statistics of the world’s most powerful single-phase transformer, which delivers 587 megavolt-amperes of power and was built by Siemens in Nuremberg, Germany. It has passed all its testing stages and is now on the way to China.

The shipment includes two VACUTAP® VR® on-load tap-changer and, at 19 meters, the longest bushings in the world. Rein­hausen France also manufactured hollow composite insulators for these parts.

This record-breaking transformer has an important assignment: It will help to ensure that 12 gigawatts of electrical power, at 1,100 kilovolts of voltage, is able to flow through the longest HVDC transmission line in the world, covering a total of 3,284 kilometers.
