T&D
Japanese companies Furukawa Electric and Fujikura have developed a superconducting cable capable of supporting currents of up to 20 kA and voltages of 10 kV.
The cables are said to be constructed from a bundle of 14 rods of an yttrium oxide-based superconducting material originally developed by Fujikura and Chubu Electric Power Co. The cables have the capacity to support a 100 kWh superconducting energy storage system, the companies claim.
