ABSTRACT:
An evaporative cooling power cable is provided with a circulating duct to act as a refrigerant passage. An insulating and liquescent cooling agent is sealed in the circulating duct to be liquified at least during part of its passage through the duct so that the liquid surface of the refrigerant is held higher than the inlet of the refrigerant to the cable. Thus, the refrigerant evaporated by the absorption of heat generated in the cable will naturally circulate the refrigerant to effectuate the cooling of the power cable.
