The utility model discloses a novel water-blocking moistureproof power cable for an offshore oil platform, which belongs to the technical field of power cables and comprises a sheath layer and a cablecore, the sheath layer is coated on the outer wall of an armor layer, the armor layer is coated on the outer wall of a reinforcing layer, the reinforcing layer is coated on the outer wall of a firstshielding layer, and the first shielding layer is coated on the outer wall of a second shielding layer. The first shielding layer wraps the outer wall of the aluminum-plastic composite water-blockinglayer, the aluminum-plastic composite water-blocking layer wraps the outer wall of the water-blocking layer, a flame-retardant layer is filled between the water-blocking layer and the cable core, thewater-blocking layer is internally provided with the water-blocking yarn, and the water-blocking yarn expands when meeting water to form a large-size colloid. The water retention capacity of the jellyis quite high, the growth of
