| Research Abstract |
MgB_2is suitable superconducting material to the mass production applications such as power cables and large coils compared with the other superconducting materials because it has many features which are a higher critical temperature(Tc) of 39 K, simple binary chemical composition, lower specific gravity and relatively low cost material. And MgB_2is the material which is interested in the application in influential liquid hydrogen temperature(20K) as a new energy source due to the higher Tc property. In this study, we investigated about the optimum wire configuration and mechanical property of MgB_2wire for the higher capacity strand cables based on the power cable application under the 20 K operation.
