Abstract

In this paper, the performance of the commercially available Bi-2223 tapes are carried out at liquid nitrogen temperature to estimate the basic characteristics of the tapes in order to design and development of superconducting cable for use in railway system applications. The current-voltage (I-V) characteristics of the tapes were studied at 77 K indicated that the critical current (I_c) is around 181-196 A. The pulse current that limited the fault current was estimated in different I_c tapes and these investigations suggested that the copper alloy protective layer was crucial to improve the over current quality. The effect of magnetic field on the critical current (I_c) of copper alloy laminated superconducting tapes show that the critical current strongly decreased with external magnetic field perpendicular to the tape surface. The results demonstrate that selection of tape and its basic characteristic are crucial importance in the design of the HTS cables.
