Production of 6.5 km GdBCO Conductors for 66 kv-5 kA Class HTS Model Cable

We have fabricated coated conductors for 66 kv-5 kA class 3-in-One 15 m HTS model cable. One of the targets of the cable is low AC loss of 2W/m/phase at 5kA. For this purpose, the coated conductors that are 2 mm wide and 4 mm wide were used for the cable. For the production, we have been developing the stable production technique of high Ic coated conductors. Recently the coated conductors for the cable were provided for the cable manufacturing.
