A 23,000 km journey from China to Brazil
Two of the transformers manufactured by Alstom Grid’s Wuhan factory (China) in the frame of Brazil’s Rio Madeira transmission line contract have arrived at the Porto Velho substation in north-west Brazil. The total journey of the transformers from Wuhan to Porto Velho took around 70 days with stops in Shanghai (China), Manaus (Brazil) and Porto Velho.
Alstom Grid’s Wuhan transformer factory successfully tested the four 600 kV DC converter transformers destined for the Brazilian Rio Madeira project in October 2012. The dielectric and performance tests are designed to respectively verify the insulation operating under high voltage stress and prove the electrical parameters of transformers. All these tests showed that the transformers perform in line with or exceed design specification.
The Rio Madeira project represents a significant challenge due to the complexity of technologies at high voltage levels, up to 600 kV. In all, Alstom will supply 28 transformers from its world class testing and manufacturing sites in Stafford (UK), Canoas (Brazil) and Wuhan (China). The transformers from Wuhan are the first ever produced by a China-based manufacturer for an export customer. Six further transformers produced by the Canoas site are currently being transported to substations in Porto Velho and Araraquara.
“The Rio Madeira project is a very important UHVDC project for Alstom Grid, representing a major technological step forward as Alstom proves its leadership in the converter transformer business. Our China industrial base proves itself ready to take up new worldwide challenges.” said Maurice Dres, Alstom Grid Vice-President for the China Region.
Built in 2009, Alstom Grid Wuhan power transformer factory is a keystone in the company’s dynamics in China. After just one year, the factory designed, built and successfully tested an 800 kV DC prototype whose design has now been used for the Rio Madeira project.

 In September 2009, Alstom was awarded an order worth approximately USD 400 million for twenty-eight 600 KVDC converter transformers, for the Rio Madeira project, a 2,375 kilometres HVDC power transmission line from the Northwest to the Southeast of Brazil. The project will be delivered for commercial operation mid-2013.
