Abstract
The invention concerns an arrangement for cooling an electric cable which comprises deep-cooled inner and outer conductors at high voltage and zero potential, respectively, and is provided with cable terminations, in which said inner and outer conductors are connected with respective inner and outer ordinary conductors. The invention consists of the provision that separate cooling loops with a common coolant supply unit are associated with the inner and outer ordinary conductors, and that likewise separate cooling loops with a common return and a further common coolant supply unit are associated with the inner and outer conductors. In this arrangement, the heat losses produced can be removed to the coolant supply units with relatively high efficiency.
