Abstract

A natural circulation type evaporative cooling electric power cable line (1) having a circulation system for the cooling medium wherein a cooling medium passage within the electric power cable line (1) has an inlet (A) and an outlet (B) respectively connected with a cooling unit (10) positioned at a level higher than the cooling medium passage inlet (A) of the cable by means of a feed pipe (4) and a return pipe (6) with a liquefiable gas cooling medium sealed therein. At least a riser portion of the return pipe (6) leading to the cooling unit (10) is installed below the level of the cooling medium return passage outlet (B) of the cable, and the return pipe 6 is provided with a device (12) for boosting circulation force without positive displacement mechanism (such as a pump or the like), so as to make the cooling medium circulate even in a low load current region which does not exceed the current allowable without cooling for that cable. <IMAGE>
