Abstract

The Melt Cast process (MCP) is highly flexible to manufacture BSCCO 2212 bulk parts in a large variety of shapes and dimensions. MCP also allows the integration of current contacts during the fabrication process thus leading to HTS parts which can directly be integrated into electrotechnical devices, The ease of mechanical treatment of the material by machining methods offers additional options for the MCP bulk parts. Critical current densities of 2.5-4 kA/cm/sup 2/ are obtained in selffield, about 1 kA/cm/sup 2/ are measured in full rods. High DC (6.4 kA) and AC (10 kA) transport currents are obtained in large tubes (O 70 mm, L 200 mm) at 77 K. Different prototypes and a first application, each of low loss hybrid current leads, have been produced as well as functional models for current limiting and for shielding. >
