The invention provides a dynamic submarine cable and static submarine cable transition assembly and a preparation method thereof. The dynamic submarine cable and static submarine cable transition assembly is composed of a cable unit, an armored transition unit and a sheath transition unit. The dynamic submarine cable and the static submarine cable are respectively composed of a cable unit, an armored steel wire and a sheath, the dynamic submarine cable and the static submarine cable adopt the same cable unit, the cable units are continuous in the production and manufacturing process, and online transition of the cable units is mainly reflected in transition of the armored unit and the sheath unit. The dynamic submarine cable adopts two layers of armored steel wires; according to the method, the factory online transition technology is adopted, so that the double-layer armoring is in online transition to one layer of armoring steel wire, and the online transition of the sheath is matched, the smooth transition of the dynamic submarine cable and the static submarine cable is ensured, the stable and efficient production of the submarine cables is realized, the use of intermediate joints is reduced, and the economy of the submarine cables is improved.
Description
technical field [0001] The invention relates to the field of submarine cables, in particular to a dynamic submarine cable and static submarine cable transition assembly and a preparation method thereof. Background technique [0002] The development of marine resources is developing towards the deep sea, and the demand for dynamic submarine cables is also increasing. Due to the high cost of dynamic cables and the long development cycle, a combination of dynamic submarine cables and static submarine cables is usually used. Generally, the dynamic submarine cable and the static submarine cable are connected in the form of an intermediate joint, but this method has high cost, long cycle and insufficient reliability. Therefore, a factory-on-line transition connection method is developed, so that the connection between the dynamic submarine cable and the static submarine cable can be completed in the factory, realizing stable and efficient submarine cable production, reducing the u...
