Patent ID: 7772158

Claim:
A resistive superconducting current limiter device having a strip-like conductor track, the conductor track comprising: a substrate strip formed of a normally conducting substrate metal; a superconducting layer formed of an oxidic high-T c superconductor material of AB 2 CU 3 O x where A denotes at least one element selected from the group consisting of rare earth metals and yttrium, and B denotes at least one alkaline earth metal; a buffer layer arranged between the substrate strip and the superconducting layer, the buffer layer being formed of an insulating, oxidic buffer material; and a cover layer formed on the superconducting layer, the cover layer being formed of a normally conducting cover layer material; and at least one electrical contact formed at one or more lateral edges of the conductor track, each of the substrate strip, the superconducting layer, the buffer layer, and the cover layer thinning in a direction of the lateral edges such that the at least one electrical contact is formed at a position in which the cover layer and the substrate strip contact each other.
