Patent AT-E400064-T1: [Translated] RESISTIVE TYPE CURRENT LIMITING DEVICE HAVING A HIGH-TC TAPE SUPERCONDUCTOR

A strip-shaped superconductor has a conductor structure containing at least one metallic substrate strip, a layer made of oxidic high T<SUB>c </SUB>superconducting material of the AB<SUB>2</SUB>Cu<SUB>3</SUB>OX type; an oxidic buffer layer, which is arranged therebetween and which has adapted crystalline dimensions, and; a normal-conductive top layer that is applied to the superconductive layer. The buffer layer should be formed so that a transition resistance of no greater than 10<SUP>-3 </SUP>Omegacm<SUP>2 </SUP>is formed at least in partial areas between the superconductive layer and the substrate strip. For example, suitable materials are of the La-Mn-O or Sr-Ru-O or La-Ni-O or In-Sn-O type.
