Abstract
The utility model discloses a marine power cable with fire-resistant cross-linked polyethylene insulation and a cross-linked polyolefin sheath. The marine power cable comprises an inner cable core consisting of a plurality of conductors by means of stranding, a fire-resistant layer and an insulating layer are wrapped outside each conductor, and an inner shielding layer, a lapping layer, an outer shielding layer and the sheath are sequentially wrapped outside the inner cable core. The marine power cable is simple in structure, and the sheath made of cross-linked polyolefin can completely adapt to operation in water and a dry cabin environment and has quite high water-proofness, insulativity and fire resistance. Simultaneously, the inner shielding layer and the outer shielding layer are designed to enhance the shielding effect of the marine power cable, and the marine power cable is fine in interference resistance and high in practicability.
