As an extension of the Melt Cast Process (MCP) the centrifugal casting technique is a flexible method for manufacturing BizSr2CaCuz0, bulk parts. It provides large scale rings and tubes, needed for high current electrotechnical applications as current leads and inductive fault current limiters. Low resistance contacts are integrated right in the fabrication process. Intrinsic (self field free) current densities up to 4 kA/cm* (T = 77 K) could be determined on small samples. Tubes with a diameter up to 70" and a length of 200" were investigated with respect to their DC and AC current carrying capability (I=7500 A, DC, 4pV/cm and L,T = 8300 A, AC, T = 77 K). This current essentially is limited by selffield effects as is shown in a numerical simulation. The quenching behaviour is related to the shape and temperature dependence of the U(& characteristics, First applications, i.e. hybrid current leads with integrated MCP bulk parts, are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
