摘要：

--A European BRITE/EURAM project for the development of current leads in the kA range using high Tc superconductor parts has been started recently. The partners in this two year project are the two chemical companies: Hoechst and Rhone-Poulenc and two companies in the field of electrical engineering: Siemens and Alcatel Alsthom. The goal of these four companies is to develop current leads for 4.2 K-systems making use of high T-c superconducting materials, to manufacture them, and to demonstrate their performance in comparison with conventional all-metal current lead. The expected benefits of this type of current leads are based on the low thermal conductivity of the ceramics and on the disappearance of ohmic losses in the temperature range of 4.2 K (liquid He) to 77 K (liquid N2) due to the superconducting state. This will result in a significant reduction of the total losses of these components in power generation, transmission and distribution systems. First results are given on Y- and Bi- based current lead models, including calculations and the, characterization of large bulk high Tc samples up to a length of 200 mm with a I-c value reaching 2000 A.
