Venturing into a new dimension of HVDC technology – Siemens is constructing a high-voltage DC link with the world’s highest ever power capacity in China

06/11/2007 | With its new system for the high-voltage DC transmission (HVDC) between the province of Yunnan in the southwest corner of China and the province of Guangdong on the south coast of the country Siemens ventures into a new dimension of HVDC technology. The system will be the first in the world to transmit electricity at a DC voltage of +/- 800 kV. At the same time this project with a power transmission capacity of 5000 MW will be the long-distance HVDC link with the world’s highest ever power capacity which has been built.
