A temperature-insulated protection type carrier communication submarine cable

Abstract

The invention discloses a temperature-insulated protection type carrier communication submarine cable, which belongs to the field of cables. A temperature-insulation protection type carrier communication submarine cable includes a central conductor whose exterior is sequentially wrapped with an inner layer insulator and an outer conductor. , the middle sheath, the outer insulator and the outer sheath, the outer insulator is mixed with extremely insulating material, the middle sheath and the outer insulator are sandwiched with a reinforced armor layer, the middle sheath, the reinforced armor layer and The outer insulator is also evacuated into a vacuum, and the surface of the outer sheath is densely covered with selective thousand-legged claws. The extreme thermal insulation material is used and applied to the production of submarine cables, and the effect of extending the thermal insulation period is very considerable. In addition, on the surface of submarine cables A selective millipede claw is added, which can select specific seabed microorganisms to attach to, and use seabed microorganisms to naturally form an "external protective layer" to strengthen the protection of submarine cables and significantly improve the stability of signal transmission.

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 ...

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.
