A pressure-resistant and heat-resistant cable Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a pressure-resistant and heat-resistant cable. Background Technology

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a cable that is like a rope, made up of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer. Cables are characterized by being energized internally and insulated externally.

[0003] In power transmission, data communication, and various industrial control systems, cables are key components for energy and information transmission. However, while traditional cable structures meet basic transmission requirements to a certain extent, they often exhibit insufficient pressure and heat resistance when facing complex and changing operating environments. In particular, under high pressure, high temperature, or high mechanical stress, cables are easily damaged, thus affecting their transmission efficiency and safety. Summary of the Invention

Through the pentagonal support frame and honeycomb frame in the insulation layer, the cable can better maintain the structural integrity and stability when subjected to external mechanical stress, extending the service life of the cable and effectively improving the pressure resistance of the cable. Through the filling layer and outer sheath, the cable can still maintain good transmission performance and safety in high-temperature environments. The outer sheath is composed of glass fiber and high-temperature wear-resistant materials, which has high strength and wear resistance, and can resist the damage of external mechanical forces to the cable, effectively protecting the cable from damage from the external environment and further extending the service life of the cable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please refer to Figures 1-4. This utility model provides a technical solution: a pressure-resistant and heat-resistant cable, comprising:

[0026] Cable core 1 has multiple components;

[0027] Insulation layer 2 is wrapped around the outer wall of each cable core 1;

[0028] A pentagonal support frame 3 is embedded in the inner wall of the insulation layer 2, and the cable core 1 is embedded in the inner wall of the pentagonal support frame 3.

[0029] Compression layer 4 is wrapped around the outer wall of insulation layer 2;

[0030] Outer protective layer 5 is wrapped around the outer wall of the compressive layer 4.

[0031] In this implementation scheme: the pentagonal support frame 3 is made of high-strength plastic. The pentagonal support frame 3 is used to isolate and fix each cable core 1, to prevent the cable core 1 from being squeezed and displaced by each other when subjected to external forces or vibrations, and to prevent the displacement between the cable core 1 from causing signal interference during transmission, thereby improving the quality and stability of signal transmission. The insulation layer 2 can tightly wrap around each cable core 1 to ensure electrical isolation. The compression-resistant layer 4 can improve the compression and heat resistance of the cable. The outer sheath 5 can protect the cable from damage caused by the external environment.

[0032] Specifically, the compression-resistant layer 4 includes a honeycomb frame 401 and a filling layer 402. The honeycomb frame 401 is wrapped around the outer wall of the insulation layer 2, and the filling layer 402 is embedded in the inner wall of the honeycomb frame 401.

[0033] In this embodiment: the honeycomb frame 401 provides a certain support capacity, effectively disperses external forces, and improves the cable's impact and compression resistance. The filling layer 402 increases the internal stability of the honeycomb frame 401, preventing it from deforming or shifting when subjected to external forces, thereby further protecting the cable. The filling layer 402 can improve the cable's thermal insulation performance, reduce the impact of external temperature on the internal signal transmission of the cable, and ensure the cable's normal operation under extreme temperature conditions.

[0034] Specifically, the material of the honeycomb frame 401 is rigid polyvinyl chloride.

[0035] In this embodiment, rigid polyvinyl chloride has excellent compressive strength, aging resistance and rodent resistance, which significantly improves the compressive strength of the cable.

[0036] Specifically, the material of the filling layer 402 is a nano-ceramic composite insulator.

[0037] In this embodiment: the nano-ceramic composite insulator has very high insulation performance, which can effectively isolate the electric field inside the cable and prevent current leakage and short circuit. The nano-ceramic composite insulator has excellent heat resistance and can withstand corrosion and wear under high temperature and high pressure.

[0038] Specifically, the material of insulation layer 2 is mineral insulating material.

[0039] In this embodiment, the mineral insulating material has good fire resistance, heat resistance, chemical resistance and impact resistance, and can withstand high temperature environment to ensure that electrical function is maintained in the event of a fire, thereby maintaining the stability of the power system.

[0040] Specifically, the outer protective layer 5 is composed of glass fiber and high-temperature resistant and wear-resistant materials.

[0041] In this embodiment, the outer sheath 5, which is composed of glass fiber and high-temperature wear-resistant materials, has high strength and wear resistance, can resist the damage of external mechanical forces to the cable, protect the cable, and has good heat resistance, can maintain structural stability in high-temperature environments, so that the cable does not soften or deform.

[0042] During use, the pentagonal support frame 3 within the insulation layer 2 prevents the cable cores 1 from being squeezed and displaced by external forces or vibrations, thus preventing signal interference during transmission due to displacement between the cable cores 1. This improves the quality and stability of signal transmission. The honeycomb frame 401 helps the cable maintain structural integrity and stability when subjected to external mechanical stress, extending the cable's service life and effectively improving its compressive strength. The filler layer 402 and outer sheath 5 ensure that the cable maintains good transmission performance and safety even in high-temperature environments. The outer sheath 5 is composed of glass fiber and high-temperature wear-resistant materials, possessing high strength and wear resistance, which can resist damage from external mechanical forces, effectively protecting the cable from environmental damage and further extending its service life.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
