Hitachi Energy has commenced the delivery of a 446-tonne transformer from Ludvika, Sweden, to China, intended for the Gansu-Zhejiang transmission link. The transformer, measuring 107 meters, is transported on a specialized beam trailer, as rail transport was not feasible.

Following a barge transfer in Köping, it will be shipped to Shanghai via Maersk. This unit, the largest of seven for the project, utilizes ultra-high-voltage direct current (UHVDC) and voltage sourced converter (VSC) technology to facilitate renewable energy transmission. Production of additional transformers will take place in China under Hitachi's supervision.
