as a structural component of the alternating-current power cable, different armor materials not only improve the mechanical protection effect, but also have great influence on the key parameter index current-carrying capacity of the power cable. Because eddy current loss and hysteresis loss of magnetic materials can be caused by the action of a magnetic field of the alternating current cable in the working process, through measuring and calculating alternating current submarine cables with different sections, if the nonmagnetic steel wire is used, the current-carrying capacity can be improved by 10% -30%;
