When the marine power cable is produced, rubber materials are plasticated, mixed and extruded on the three cables 1 to form the mounting columns 2, and after the mounting columns 2 are cooled and formed, the three cables 1 are uniformly distributed on the mounting columns 2 along the axes of the mounting columns 2. The number of cables 1 may be one, two or more than three in other embodiments.

When water around the marine power cable flows onto the hydrophobic layer 5, the water falls on the surface of the hydrophobic coating 51, the hydrophobic coating 51 receives the water due to the hydrophobicity of the hydrophobic coating 51, the water does not easily pass through the hydrophobic coating 51, and when the hydrophobic layer 5 is aged or the hydrophobic property of the hydrophobic coating 51 is lowered, the water may pass through the hydrophobic layer 5 to flow onto the water absorbing layer 4, and the water absorbing layer 4 absorbs the water and stores the water into the water absorbing holes 41, reducing the erosion of the mounting post 2 by the water. After water passes through the hydrophobic layer 5 and the water absorbing layer 4, the waterproof glue 7 blocks the water in the water absorbing layer 4, so that the water is not easy to contact with the mounting column 2. The erection column 2 separates water from the cable 1, and when the erection column 2 ages or is damaged, water may flow into the insulating layer 6 through the erection column 2, the insulating layer 6 separates water from the cable 1, when the insulating layer 6 ages or is damaged, water flows onto the waterproof membrane 3 through the insulating layer 6, and the waterproof membrane 3 separates the cable 1 from water again, so that water is not easy to contact with the cable 1, and the waterproof performance of the cable 1 is further improved.
