Double-core direct-current submarine cable

The utility model relates to a double-core direct current submarine cable, which comprises two wire cores with semicircular cross sections, the plane sides of the two wire cores are attached to each other, a cabling wrapping tape, an inner lining layer, a steel wire armor and an outer coating layer are sequentially wrapped outside the two wire cores, a filling material is arranged in a gap between the wire cores and the cabling wrapping tape, and the outer coating layer is arranged between the wire cores and the cabling wrapping tape. Each wire core comprises a water-blocking conductor, and a conductor shielding layer, an insulating layer, an insulation shielding layer, a semi-conductive water-blocking tape and a water-blocking sleeve are sequentially wrapped outside the water-blocking conductor. According to the utility model, two wire cores can be integrated into a single cable, the number of cables is reduced, the construction period is shortened, the occupied space is reduced, the requirement for filling
