[Also in Division F4] In a closed cooling system for an electric power cable 1, the cable is cooled by oil circulated after cooling in a heat exchanger 16 or 16SP1/SP alternately in opposite directions through the cable, between sealed oil containers 8, 81 one at each end of the cable, one at least of these containers (both in the form shown) having a wall deformable by an externally applied fluid pressure whereby flow of cooling oil through the cable may be induced by generating a pressure differential between the two containers 8, 8SP1/SP. In the system shown each of the containers 8,8SP1/SP comprises interconnected lenticular cells housed in a casing 10 or 10SP1/SP filled with an appropriate liquid or gaseous fluid pressurized as necessary by a pump 12 or 12SP1/SP to provide the required pressure differential in the cable oil. The pressurizing fluid system includes storage tanks 14 or l4SP1/SP.
