ABSTRACT:
An internally cooled high-energy cable is equipped with terminal connector assemblies for supplying electric current thereto and withdrawing the current therefrom, and with terminal connector assemblies for supplying a cooling medium to the cable and discharging the spent cooling medium therefrom. A connecting pipe connects the two assemblies at each end of the cable and conducts the cooling medium from one to the other. The flow-through cross section of the channel for conducting the cooling medium through the cooling medium terminal connector assembly is smaller than the flow-through cross section of the cooling channel of the cable which results in more rapid flow of the cooling medium through the former channel and in enhanced cooling effect, so that the heat resulting from the decline in the electric potential of the cooling medium in the cooling medium terminal connector assembly is effectively dissipated. The channel in the connecting pipe may decrease from a cross section corresponding to the cross section of the cooling channel of the cable to that corresponding to the cross section of the cooling channel in the cooling medium terminal connector assembly whereby the region of turbulent flow caused by the reduction in the flow-through cross section is distant from the cooling medium terminal connector.
