ABB to supply worlds longest underground cable system
ZURICH – ABB has won an order worth around $160 million from Svenska Kraftnät, the national grid operator, to provide a new high-voltage underground cable system for the South-West Link power transmission project in southern Sweden. When completed in 2014, this will be the longest and most powerful underground cable link in the world. The order was booked in the fourth quarter of 2011.
The main objective of the new transmission system is to enhance capacity and strengthen the reliability of the national power grid. It will help boost transmission capacity in the south of the country and between Sweden and Norway. The link will also facilitate the future integration of large-scale wind power into the Swedish power network.
ABB's underground HVDC (high-voltage direct current) cable system will have the capacity to transport 2 x 660 megawatts (MW) of electric power at a voltage level of 300 kilovolts (kV) across a distance of about 200 kilometers between Barkaryd and Hurva in southern Sweden. ABB is responsible for the design, engineering, manufacture, supply and installation of the entire cable system, including terminations, joints and other accessories.
"This cable solution will boost power capacity, facilitate power exchange and help integrate more renewable energy," said Peter Leupp, head of ABB's Power Systems division. "It will also reduce the impact of power system disturbances and contribute to the stability and reliability of the grid."
