It works. Record-breaking transformer for China.

37.5 meters long
14.5 meters high
12 meters wide
909 met­ric tons

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.
