Thermal insulation protection type carrier communication submarine cable

Abstract

The invention discloses a thermal insulation protection type carrier communication submarine cable and belongs to the field of a cable. The cable comprises a central conductor, wherein an inner-layerinsulator, an outer conductor, a middle sheath, an outer-layer insulator and an outer sheath are sequentially wrapped outside the central conductor from inside to outside, extremely heat preservationmaterials are doped in the outer-layer insulator, a reinforcing armor layer is clamped between the middle sheath and the outer-layer insulator, the space among the middle sheath, the reinforcing armorlayer and the outer-layer insulator is further vacuumized, and selective thousand-foot guide claws are densely distributed on a surface of the outer sheath. The extremely thermal insulation materialsare adopted and applied to manufacturing of submarine cables, the effect of prolonging the heat preservation period is very considerable, the selective thousand-foot guide claws are additionally arranged on a surface of the submarine cable, the selective thousand-foot guide claws can select specific submarine microorganisms to be attached, an external protective layer is naturally formed by utilizing the submarine microorganisms, protection of the submarine cable is enhanced, and stability of signal transmission is remarkably improved.

Description

technical field [0001] The invention relates to the field of cables, and more specifically relates to a temperature-insulation-protected carrier communication submarine cable. Background technique [0002] Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern undersea cables use fiber optics to transmit telephone and internet signals. The world's first submarine cable was laid between England and France in 1850. China's first submarine cable was completed in 1988. The core of the submarine cable is made of high-purity optical fiber as thin as a hair, which guides light along the path of the optical fiber through internal reflection. Submarine cables must be able to withstand the enormous pressure of 8 kilometers underwater, which is equivalent to the weight of an elephant placed on a human thumb. Submarine ...

AI Technical Summary

Problems solved by technology

At present, the submarine cables are 39,000 kilometers long, connecting 33 countries and four continents. Although sharks were recorded by cameras to destroy submarine cables once, after 2006, sharks and other fish caused less than 1% of submarine cable failures.

[0008] Although the existing carrier communication submarine cables are deep in the seabed, their thermal insulation is still required to be strictly guaranteed. However, the existing submarine cables have a general thermal insulation effect and a short thermal insulation period. Biological gnawing causes its surface to be damaged, and further erodes into the interior of the cable, causing damage to the submarine cable. Once the submarine cable is damaged, it will cause signal transmission failure at least, and cause the entire operating carrier communication system to collapse.
