The contract, worth 100 millions euros, was signed with the State Grid of China. The systems will be delivered in December 2010.
HVDC technology connects power networks and transmits large amounts of electricity over long distances with minimal losses.
With plans to transmit more than 130 GW of electricity over the next five to ten years, Chinas needs in HVDC are booming.
This success will strengthen Arevas position on the domestic HVDC market and demonstrates the companys ability to meet Chinas needs.
