“…In figure 3 the AC losses per cycle and per meter are shown for the cable core and the cable shield for different frequencies being recalculated per one tape. For comparison, the measured AC losses are shown in the shield of compact 2G HTS cables we produced and tested earlier [1]. AC losses in the shield are practically the same as in our first compact cable described in [1], while in the core AC loss are slightly less in this cable due to less width of the tapes.…”

In Russian Scientific R&D Cable Institute we continue studies to develop as compact as possible 2G HTS power cables for electric power systems. Compact cables should have minimized diameter compared to other co-axial HTS cables developed before. Recently we developed the cable prototype with four HTS layers in the core and two layers in the shield. Numerical optimization of compact cables has been used together with manufacturing technology to produce small diameter cables with uniform current distribution. The first cold test of the compact cable demonstrated that we were able to control the homogeneous current distributions in a compact cable with the inner diameter of the core ~10 mm and the outer diameter of the shield ~20 mm. In this work we present more test results of this cable, including, mechanical test and high voltage tests. New test results demonstrated very high parameters of the compact cable developed. The compact cables perspectives for electric systems are discussed.
