Fujikura Announces Superconducting Power Cable With 1/4 Transmission Loss

Fujikura Announces Superconducting Power Cable With 1/4 Transmission Loss May 31, 2013 12:16 Masaru Yoshida, Nikkei Monozukuri Sumitomo Electric Industries Ltd, Fujikura Ltd and International Superconductivity Technology Center (ISTEC) developed large-current, low-loss 66kV superconducting power cables by using yttrium (Y)-based high-temperature superconducting wire materials. Especially, the cable developed by Fujikura enables to reduce power transmission loss (in consideration of cooling efficiency) by 75% or more. Sumitomo Electric Sumitomo Electric established a 15m-long 66kV three-core superconducting cable system by using an Y-based superconducting wire material developed by the company (Three high-temperature superconducting cable cores are stored in one insulated pipe). It has the world's highest power transmission density and can be stored in a 150mm-diameter pipe...
