ABB says it has successfully developed and tested a 1,100 kV ultrahigh-voltage direct-current converter transformer.

The Xiangjiaba-Shanghai link, which was commissioned by ABB, has a capacity of 6.4 GW and covers a distance of just over 2,000 km, making it the longest of its kind in operation, according to the company. The new 1,100 kV converter transformer technology will make it possible to transmit more than 10 GW of power across distances as long as 3,000 km.

Converter transformers play a critical role in high-voltage direct-current transmission, serving as an important interface between the DC link and the AC network, according to ABB. Development of the 1,100 kV transformer addressed several technology challenges, such as the sheer size and scale, and electrical insulation, including bushings and thermal performance parameters.

"This new 1,100 kV transformer technology will make it possible to transmit even more electricity efficiently and reliably, at higher voltage levels, across greater distances with minimum losses," says Bernhard Jucker, head of ABB's power products division.
