ABB, the leading power and automation technology group, has achieved another significant milestone with the commissioning of the Xiangjiaba-Shanghai project, the world's first UHVDC (ultrahighvoltage direct current) transmission link to go into commercial operation. ABB was the main technology supplier to State Grid Corporation of China (SGCC) and the project was completed in 30 months, one year ahead of schedule.
The ±800 kV Xiangjiaba-Shanghai UHVDC link has the capacity to transmit up to 7,200 megawatts (MW) of power from the Xiangjiaba hydropower plant in southwest China to Shanghai, the country's leading industrial and commercial center about 2,000 kilometers away.
