Deep sea cable

Abstract

The invention discloses a deep sea cable. A filling layer is covered with a wrapping tape layer, the center of the filling layer is filled with a reinforcing inner core, three power cables are evenly distributed on the outer ring of the reinforcing inner core, the wrapping tape layer is covered with a metal shielding layer in an adhesion mode, the metal shielding layer is covered with an inner coating, the inner coating is covered with an armor layer, the gap between the inner coating and the armor layer is filled with a water-resisting factice layer, the armor layer is sleeved with an outer coating, and an external fixing concave groove is formed in the outer coating. According to the deep sea cable, the water-resisting factice layer and the filling layer achieve the effects of two water-resisting tapes from outside to inside, the metal shielding layer achieves the electromagnetic interference preventing effect, the filling layer and the reinforcing inner core both achieve the effect of reinforcing the strength of the cable, a balance weight can be installed in the external fixing convex groove in the outer coating, the adhesive force of the cable to the sea bed can be enhanced, and the influences of sea bed ocean currents on fixation of the cable are well avoided.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a deep-sea cable. Background technique [0002] Submarine power cables are the cables with the highest requirements on cable performance. They not only need to meet the needs of high-strength pulling and wear resistance during laying, but also need to be able to resist high-pressure and high-corrosion environments on the seabed. Ships in When the power cable is laid on the water surface, it is easy to be interfered by the electromagnetic wave generated by the submarine cable, which poses a threat to the normal operation of the ship. In the deep sea, the ocean currents are very frequent. The traditional submarine cable is generally fixed by sea mud covering. , there is a problem of loose fixation, and the cable line is easily displaced and damaged by ocean currents.

Problems solved by technology

[0002] Submarine power cables are the cables with the highest requirements on cable performance. They not only need to meet the needs of high-strength pulling and wear resistance during laying, but also need to be able to resist high-pressure and high-corrosion environments on the seabed. Ships in When the power cable is laid on the water surface, it is easy to be interfered by the electromagnetic wave generated by the submarine cable, which poses a threat to the normal operation of the ship. In the deep sea, the ocean currents are very frequent. The traditional submarine cable is generally fixed by sea mud covering. , there is a problem of loose fixation, and the cable line is easily displaced and damaged by ocean currents. Chinese patent CN 102693776A discloses a three-core optical fiber composite submarine cable, including a cable core and at least one optical cable unit. The cable The core and the optical cable unit are wrapped together by a rubberized cloth layer, and a filler is arranged between the cable core and the optical cable unit. The rubberized cloth layer is provided with an inner liner, a steel wire armor layer and an outer layer in sequence. There are three cable cores, and the cable cores are parallel to each other and form a loop. Each cable core includes a water-blocking conductor and an insulating layer, shielding layer, water-blocking layer, lead layer and Sheath layer

Although the above-mentioned three-core optical fiber composite submarine cable has solved the problems of electromagnetic interference and waterproof, the problems of anti-pull, corrosion resistance and fixation are still not well resolved.
