ABSTRACT:
A cable shaped cryogenically stabilized heavy current superconductor contains several superconducting elements embedded in a matrix material and several stabilizing elements arranged parallel thereto, the electric conductivity of which, in the normally conducting state of the conductor, is substantially higher than that of the matrix material. These elements are fastened on a support body of low electric and thermal conductivity. The stabilizing elements are arranged on the support body physically separated at predetermined spacings from the respective adjacent superconducting elements and the spaces thus formed between the adjacent superconducting elements and the stabilizing elements is filled, at least largely, with a cryogenic coolant. Due to the small coupling between the superconducting elements and their associated stabilizing elements, good cooling of the conductor and relatively low-loss operation can be ensured even in applications with alternating fields.
