Provided is a submarine cable. The submarine cable sequentially comprises a submarine section, an ashore section and an air section, wherein the ashore section comprises a cable body, and the cable body comprises a cable core and a lining layer which wraps the outer surface of the cable core; the cable body is sleeved in a steel pipe, the steel pipe is of a hollow structure, and a heat radiating medium of which the heat resistance coefficient is smaller than that of air is arranged between the inner wall of the steel pipe and the lining layer of the cable body. As the heat resistance coefficient of the heat radiating medium is smaller than that of air, the heat of the ashore section can be conveniently radiated, and the current carrying capacity of the ashore section is improved. And meanwhile, the unvaried cross section of a conductor of the ashore section and the arrangement of the steel pipe ensure that the ashore section can adapt to mechanical stress during laying or reworking. Therefore, the current car
