Abstract

A multilayer superconducting wire 7 with essentially round cross sectional area where the outer surface of the round wire is provided with a high temperature superconductor layer 3 and where at least the high temperature superconductor layer 3 is fabricated as a spiral running along the length of the superconductor wire 7 in parallel lanes 15.
