OREANDA-NEWS. June 30, 2011. Furukawa Electric has developed a 275kV superconducting power cable of the highest voltage class in the world.

Utilizing the Yttrium-based superconducting wires, which boast excellent cost performance, the superconducting power cable has doubled the voltage performance and tripled the power performance of conventional cables through improving the technologies for conversion to cable. It has also halved the AC loss of conventional cables, enabling massive amounts of electricity to be carried with low loss.

These results were achieved through the “Technology development project of the Yttrium-based superconducting power device (Project leader: Yuh Shiohara, Director General of the International Superconductivity Technology Center)” commissioned by the New Energy and Industrial Technology Development Organization (NEDO).
