Technical Field

[0002] Deepwater communication cables are mainly used in the communication industry such as telephone and network, and they carry the transmission task of the global Internet. These cables realize long-distance and high-speed signal transmission through optical fiber technology, allowing people around the world to exchange information conveniently. With the continuous development of technology, the transmission capacity and efficiency of deepwater communication cables are also constantly improving, providing strong support for the informatization process of human society. The laying of deepwater cables is a complex and delicate process that requires consideration of multiple factors such as seabed topography, ocean currents, and marine life. In order to ensure the safety and stable transmission of cables, deep burial, warning signs, and sea map markings are usually taken to avoid being scratched by ships or submarines. At the same time, it is also necessary to regularly maintain and inspect the cables to promptly detect and deal with potential problems.

[0003] In order to ensure the stability of signal and power transmission and improve the durability and service life of cables, pressure-resistant and heat-insulating cables are needed. Existing deep-water cables only adopt a single-layer pressure-resistant and heat-insulating structure, which is relatively simple as a whole. Its pressure-resistant and heat-insulating performance still has certain limitations, which reduces the overall service life of the cable. Therefore, it is necessary to propose a deep-water cable with pressure-resistant and heat-insulating properties. Summary of the invention

[0004] The purpose of the present invention is to provide a deep-water cable with pressure resistance and heat insulation, which has the characteristics of increasing the pressure resistance and heat insulation performance of the cable while improving the overall service life of the cable by combining multiple pressure-resistant layers and multiple heat-insulating layers.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a deep-water cable with pressure resistance and heat preservation, comprising a plurality of conductors and an inner insulation pad, the outer wall of the inner insulation pad being embedded with a plurality of evenly distributed grooves, the plurality of conductors being respectively installed in the plurality of grooves, the outer wall of the inner insulation pad being fixedly connected with a plurality of insulating layers wrapped around the outer wall of the conductor, the outer wall of the insulating layer comprising a first pressure-resistant layer, a second pressure-resistant layer being fixedly connected between two adjacent first pressure-resistant layers, a third pressure-resistant layer being fixedly connected between two adjacent second pressure-resistant layers, the interior of the second pressure-resistant layer being filled with a first insulation layer, the interior of the third pressure-resistant layer being filled with a second insulation layer, and the outer walls of the plurality of third pressure-resistant layers being provided with a tensile-resistant layer.

[0006] In order to enhance the compression resistance of the cable, as a preferred deep-water cable with compression resistance and heat preservation of the present invention, the first compression-resistant layer, the second compression-resistant layer and the third compression-resistant layer are all made of metal materials.

[0007] In order to enhance the compression resistance of the first, second and third compression resistant layers, as a preferred deepwater cable with compression resistance and heat preservation of the present invention, the first, second and third compression resistant layers are all semicircular.

[0008] In order to improve the overall thermal insulation performance of the cable, as a preferred deep-water cable with pressure resistance and thermal insulation of the present invention, the inner thermal insulation pad, the first thermal insulation layer and the second thermal insulation layer are all rubber plastic cotton.

[0009] In order to make the cable have good waterproof performance, as a preferred deep-water cable with pressure resistance and heat preservation of the present invention, the outer wall of the tension-resistant layer is provided with a waterproof layer.

[0010] In order to make the cable have good corrosion resistance, as a preferred deep-water cable with pressure resistance and heat preservation of the present invention, the outer wall of the waterproof layer is provided with a corrosion-resistant layer.

[0011] In order to improve the tensile strength and durability of the cable, as a preferred deep-water cable with compression resistance and heat preservation of the present invention, the tension-resistant layer is made of aramid fiber material.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention can perform primary, secondary and tertiary insulation on the conductor through the cooperation of the inner insulation pad, the first insulation layer and the second insulation layer, so as to improve the overall insulation performance of the cable; Through the cooperation of the first pressure-resistant layer, the second pressure-resistant layer, the third pressure-resistant layer and the tensile-resistant layer, the conductor can be subjected to primary, secondary and tertiary compression and tension resistance, thereby increasing the overall compression and tensile resistance of the cable. In summary, the purpose of increasing the compression and thermal insulation performance of the cable while improving the overall service life of the cable can be achieved by combining multiple pressure-resistant layers and multiple thermal insulation layers.
