LS Cable Ltd.has ordered 80,000 meters (50 miles) of 344 superconductors, American Superconductor Corp.'s second generation high-temperature superconductor (HTS) wire. LS Cable will use the wire to manufacture a 22.9 kV cable system that it will install in Korea Electric Power Corp.’s (KEPCO) commercial power delivery network near the city of Seoul in 2010. Founded in 1962 and based in Anyang, South Korea, LS Cable is Korea’s largest power cable manufacturer with nearly 8,200 employees worldwide and annual sales in excess of US$6 billion. This is the single largest commercial order for 2G HTS wire in the world, according to AMSC.
“With the ability to carry vast amounts of electricity in a small right of way, superconductor power cables will play a pivotal role in powering cities in Korea and around the world in the 21st Century,” said Joon Hyung Cho, executive vice president of LS Cable’s Technology Development Group. “We have chosen to work with AMSC on this landmark cable project based on the company’s two decades of superconductor leadership, its contributions to LS Cable’s past superconductor cable demonstrations and the strength of its new 344 superconductors. We see a billion-dollar opportunity for superconductor cable technology and believe our alliance with AMSC and KEPCO establishes a market leadership position for LS Cable.”
Under the terms of the contract, AMSC will deliver the wire to LS Cable by the end of 2009. LS Cable will then strand the wire into a superconductor cable system capable of carrying 50 MW of power. The cable system will be nearly a half mile in length, making it the world’s longest distribution-voltage superconductor cable system. It is scheduled to be installed by the middle of 2010 and energized in one of Seoul’s largest satellite cities by the end of 2010.
“As is the case in many countries around the world, Korea has been experiencing sharp increases in electricity demand and is relying more and more on renewable energy sources to meet that demand,” said KEPCO Chief Executive Officer Kim Ssang-Su. “With their ability to carry a vast amount of power in a small pathway, we see great promise for superconductor cable technology and look forward to energizing this first system.”
This project builds on the success Korea’s Development of Advanced Power Systems by Applied Superconductivity technologies (DAPAS) program, which has provided more than $100 million in funding for the development and commercialization of superconductor systems. In 2006, LS Cable and the Korea Electrotechnology Research Institute (KERI) successfully tested a 30-meter, 22.9kV superconductor cable. In 2007, LS Cable and KERI completed testing of a 100-meter, 22.9 kV superconductor cable system. Both of these projects were powered by AMSC’s first generation HTS wire and funded by the DAPAS program.
