ABB certifies first 1100kV DC transformer
ABB has certified the low and high voltage units of the world’s most powerful ultrahigh-voltage direct current (UHVDC) transformer.
Mr. Liu ZeHong, Executive Vice President of SGCC.

China has major consumption centres in the east of the country while a significant amount of its energy resources are in the west and northwest. This has stimulated the development of ultrahigh voltage links to increase transmission capacity while minimising losses.

ABB has been working on HVDC technology more than 60 years ago and is the global market leader with over 110 HVDC projects, representing a total installed capacity of more than 120,000 megawatts - around half of the world’s installed base. In 2010 ABB supported SGCC with the Xiangjiaba-Shanghai project, the world’s first ±800kV UHVDC link to go into commercial operation.
