送電ケーブル (3)AC loss characteristics in monolayer and multi-layer power transmission
cables: gap effect

1. Introduction
Superconducting power transmission cables comprisingcoated conductors have attracted broad attention as one of themost valuable and feasible applications of high Tc
superconductors. AC loss reduction is one of the critical issues
for their introduction to power grids. This paper presents acomprehensive analysis on the influence of gaps between
coated conductors (tapes) to AC losses of monolayer andmulti-layer power transmission cables, named gap effect.
Numerical results have shown that gap effect significantly
influences AC losses of monolayer cables, but the gap effect inmulti-layer cables has not been clarified well. Firstly, the gap
effect to cables constructed with different number of layers is
discussed. Furthermore, the variation of AC losses ofindividual layers in a 6-layer cable is analyzed. Secondly, AClosses of cables with different critical current distributions arecalculated. The results are presented and discussed forcomparing the influences of critical current and gap effect.

result essentially explains why 6-layer cables are hardly
influenced by gap effect.
3. Conclusion
Gap effect substantially influences AC losses of monolayer
cables, while hardly affecting cables with many layers. Thisknowledge is very useful for designing and fabricating
practical cables.

2. Numerical results and analysis
All the AC losses are calculated with a numerical model
employing 1D FEM [1]. As shown in Fig. 1, 4 types of cables
are analyzed. These cables are classified into 3 groups in termsof the size of gaps, including small gap, medium gap and large
gap, shorted as SG, MG and LG, which are 0.26 mm, 0.36 mm
and 0.56 mm respectively. Detailed properties of cables arelisted in Table 1.

The numerical results presented in Fig. 2 show that AC
losses increase while applying trapezoidal Jc with bigger
shoulder. However, no matter what style the Jc profile is, alongwith the increase of layers, the differences of AC losses
between cables with SG, MG and LG are getting smaller,
indicating that gap effect performs more influence to cables
with fewer layers, for instance monolayer and 2-layer cables,
while hardly influencing cables with many layers, specifically
6-layer cables. This result proves that, for multi-layer cables,
small gaps are not absolutely essential to reduce AC losses.
Fig. 3 shows the AC loss distribution among layers in a
6-layer cable. By increasing the size of gaps, inner layers are
more affected and generate more AC loss, while the AC losses
of outer layers decrease, which counteracts the increases. This
