A kind of cable and cable assembly

Abstract

The invention provides a cable and a cable component. The cable comprises a cable reinforcing core, conductors, a wrapping layer for wrapping the cable reinforcing core and the conductor, a tensile and compressive mechanism for protecting the cable, and an adaptive protection mechanism for assisting the cable to adapt to an underwater environment. The surface of the cable reinforcing core is sleeved with an inner wrapping layer, the plurality of conductors are arranged around the cable reinforcing core, and the surface of each conductor is sleeved with an insulating layer. The invention relates to the field of cables. According to the cable and the cable component, two mutually associated special structures are arranged, for the problems of cables under trees, the large pressure borne by the cable is relieved, and the underwater adaptability of the cable is enhanced, thereby effectively solving the problems that when a common cable is used underwater, the pulling time and strength of the cable are large, the cable is liable to be rolled, the internal structure of the cable is liable to be delaminated and damaged, the maintenance work difficulty of the damaged cable is large, and the cost is high.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable and a cable assembly. Background technique [0002] At present, the field of cable application is very wide. With the development of offshore industry, the use of cables on the seabed has become very common, and some problems that follow also need to be solved. For example, in seawater, due to the fluidity of seawater, the cable is easily crushed by water pressure and reefs that may move at any time after laying, causing severe damage to the internal structure of the cable, which will affect the normal use of the cable. [0003] In addition, due to the heavy gravity of the cable itself, when sinking to the bottom, the suspension cable between the water surface and the bottom will be subjected to a great pulling force, and the use of underwater cables will often be dragged and pulled. Local force will be applied at the drag point, the connecting layer will easily slip off,...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a cable and a cable assembly, which solves the problem that when the general cable is used underwater, the cable pulling time and strength are relatively large, and the cable is easily crushed, which may easily cause damage to the internal structure of the cable. Delamination and damage, a difficult and costly problem to repair damaged cables
