Embodiment Construction

[0062] Dynamic and static submarine cables usually include connected dynamic cables and static cables. Both dynamic cables and static cables include a cable core and an armored layer covering the cable core. Since the dynamic cable is set in seawater, the static cable is buried in the seabed. , so that the impact and wear of the static cable is less than that of the dynamic cable, so the number of armor layers of the static cable is usually less than that of the dynamic cable, making the structure of the dynamic cable different from that of the static cable. In the related technology, the dynamic cable and the static cable are generally produced separately, and then the maintenance joint box is used to connect the core and armor layer of the dynamic cable and the static cable to realize the transition between the dynamic cable and the static cable to form a dynamic and static submarine cable. . However, separately producing the dynamic cable and the static cable will increase ...

Abstract

The invention provides a dynamic and static submarine cable and a manufacturing method thereof, relates to the technical field of submarine cables, and is used for solving the technical problem that the production period of the dynamic and static submarine cable is relatively long. The dynamic and static submarine cable comprises a continuous cable core, wherein the cable core comprises a dynamic section, a static section and a transition section for connecting the dynamic section and the static section; a first armor layer which sleeves the outer sides of the dynamic section, the static section and the transition section; a transition device which sleeves the outer side of the first armor layer corresponding to the transition section; and a second armor layer arranged outside the first armor layer corresponding to the dynamic section in a sleeving mode, wherein the first end of the second armor layer covers part of the transition device, and the first end of the second armor layer is welded to the peripheral face of the transition device. The dynamic and static submarine cable provided by the invention is used for electric conduction and communication.

Description

technical field [0001] The invention relates to the technical field of submarine cables, in particular to a dynamic and static submarine cable and a manufacturing method thereof. Background technique [0002] Dynamic and static submarine cables usually include connected dynamic cables and static cables. The dynamic cables are set in seawater and will continue to move under the influence of environmental factors such as wind, waves and currents. The static cables are buried on the seabed and are less affected by environmental factors. There is no sustained motion. With the development and utilization of marine resources, offshore platforms such as offshore oil and gas platforms, offshore wind turbines, wave energy generators, and tidal energy generators are gradually increasing, and the demand for dynamic and static submarine cables is also gradually increasing. [0003] Due to the different working conditions, the structure of the dynamic cable and the static cable are diff...
