Sumitomo Electric (SEI) has been involved in the development of 66 kV-class HTS cables using REBCO wires. One of the technical targets is to reduce the AC loss to less than 2 W/m/phase at 5 kA. SEI has developed a clad-type textured metal substrate with lower magnetization loss than NiW substrate. REBCO tapes 30 mm-wide were slit into 4 mm-wide strips, and these strips were wound spirally on a former with small gaps. The measured AC loss of the manufactured cable was 1.8 W/m/phase at 5 kA, achieving the AC loss goal.
