ABSTRACT:
A cable for transmitting high electric energies comprises an inner tubular member which is provided with a channel for conducting a cooling medium, an outer tubular member surrounding the inner tubular member, a cable jacket surrounding the outer tubular member with spacing, and an insulation provided intermediate the outer tubular member and the cable jacket. The inner and outer tubular members are circumferentially complete so that the cooling medium cannot escape into the insulation and cause damage thereto. The inner tubular member may itself serve as an electric conductor, or a separate electric conductor may be situated intermediate the inner and the outer tubular members.
