ABB has won an order worth around $75 million to supply advanced converter transformers for the Belo Monte 800 kV ultra-high-voltage direct current (UHVDC) transmission link. The 2,518 km link will transmit clean power generated in the north of Brazil, from the Xingu substation, to the Rio Substation in the southeast. It will be capable of transporting up to 4000 MW of electricity – enough to meet the needs of around ten million people. The order was booked in the fourth quarter of 2016.
ABB supplies for the Belo Monte UHVDC link include fourteen 400 MVA, 400 kV converter transformers and other related equipment. Converter transformers are among the most vital components in a transmission system, enabling grid stability and power reliability, while minimizing losses.
UHVDC is an advancement of HVDC, a technology pioneered by ABB over 60 years ago, and represents the biggest capacity and efficiency leap in over two decades. ABB was the first to successfully develop and test 1,100 kV converter transformer technology setting the record for the highest DC voltage levels ever and making it possible to increase the power transmission capacity of UHVDC links to the unprecedented level of 12000 MW.
Transformers are integral components of an electrical grid enabling the efficient and safe conversion of electricity to different voltages. ABB’s transformers are designed for reliability, durability and efficiency with a portfolio that includes power transformers rated up to 1,200 kV, dry- and liquid-distribution transformers, traction and special application transformers and related components.
