Load-controllable light marine power cable

The utility model relates to the technical field of power cables, and provides a load-controllable light marine power cable, which comprises a hollow pipe, a conducting layer and a protective layer which are sequentially arranged from inside to outside, the conducting layer wraps the hollow pipe, the protective layer wraps the conducting layer, and cooling liquid circulates in the hollow pipe. According to the technical scheme, the protective layer wraps the conductive layer to protect the conductive layer, meanwhile, the conductive layer achieves electric conduction, and the conductive layer wraps the outer surface of the hollow pipe, so that when the conductive layer is overheated, cooling liquid can be injected into the hollow pipe to cool the conductive layer through the hollow pipe, and the current-carrying capacity of the conductive layer is improved. 本实用新型涉及电力电缆技术领域，提供一种可控负载轻型船用电力电缆，包括由内向外依次设置的中空管、导电层及保护层，导电层包覆中空管，保护层包覆导电层，且中空管内流通有冷却液。通过设置保护层包覆于导电层，对导电层进行保护，同时，导电层实现导电，并把导电层包覆在中空管外表面，如此，在导电层过热时，可通过往中空管内
