1. A power cable assembly comprising:
a power cable core including:
a longitudinally extending cooling tube comprising a thermally conductive wall defining an interior channel for circulating a coolant medium between a coolant inlet and a coolant outlet of the cooling tube;
a longitudinally extending electrical conductor configured to be coupled to respective electrical connections of a power distribution system via first and second electrical connectors, wherein the electrical conductor is extruded over the cooling tube and wherein the electrical conductor is in the form of a busbar configured to be wrapped around the cooling tube; and
a first insulating layer surrounding the power cable core, wherein the electrical conductor is arranged to completely surround the cooling tube such that at least a portion of an external surface of the thermally conductive wall is provided in direct contact with a corresponding portion of the electrical conductor over a heat exchange region so as to transfer heat from the electrical conductor to the coolant medium circulating in the interior channel of the cooling tube.
