MELT CAST PROCESSED (MCP)-BSCCO-2212 TUBES FOR POWER APPLICATIONS UP TO 10 KA

The Melt Cast Process (MCP) is highly flexible to manufacture BSCCO 22 12 bulk parts in a large variety of shapes and dimensions. MCP also al lows lows the integration of current contacts during the fabrication p rocess thus leading to HTS parts which can directly be integrated into electrotechnical devices. The ease of mechanical treatment of the mat erial by machining methods offers additional options for the MCP bulk parts. Critical current densities of 2.5-4 kA/cm(2) are obtained in se lffield, about 1kA/cm(2) are measured in full rods. High DC (6.4 kA) a nd AC (10 kA) transport currents are obtained in large tubes (O 70mm, L 200 mm) at 77K. Different prototypes and a first application, each o f low loss hybrid current leads, have been produced as well as functio nal models for current limiting and for shielding.
