ABSTRACT:
The invention concerns apparatus for cooling an electric cable which comprises superconducting inner and outer conductors, is subdivided into at least two cable sections and is provided with cable terminations in which these inner and outer conductors are connected with respective inner and outer ordinary conductors. According to the invention, a common coolant stream for the inner conductors and inner ordinary conductors as well as for the outer conductors and outer ordinary conductors is provided for each cable termination and the cable section associated with it, the coolant being fed-in at that end of the cable section which is not connected with the cable termination. With this simple arrangement, quantities of dissipation heat produced can be removed to refrigeration machinery with relatively high efficiency.
