Description

Technical Field

[0001] This utility model relates to the technical field of wires and cables, and in particular to a composite air-conducting cable. Background Technology

[0002] The wire and cable industry is an important supporting industry for economic development, widely used in various sectors of the national economy. In some special applications, such as oil well sensor cables, a venting pipe needs to be installed within the cable.

[0003] Currently, existing composite cables with vent tubes generally have the cable directly arranged with the conductor and steel core, and a wrapping layer, shielding layer and outer sheath are installed on the outside of the vent tube, conductor, and steel core.

[0004] However, during long-term use, the outer sheath of the gas tube and the electrical cable are easily worn due to mutual friction and compression. This may even damage the insulation layer of the internal wires, causing safety hazards such as short circuits and leakage. It will also reduce the service life of the gas tube and increase the risk of gas leakage. Utility Model Content

[0005] The purpose of this invention is to provide a composite air duct cable to solve the technical problem of mutual friction and compression between air ducts and electrical cables during long-term use in the prior art.

[0006] This utility model provides a composite air-conducting cable, which includes a conductor, a filler rope, an air-conducting tube, a wrapping layer, a braided layer, and an outer sheath.

[0007] The wrapping layer is disposed on the outside of the core wire and the air guide tube. The filler rope is filled inside the wrapping layer and disposed in the gap between the core wire and the air guide tube. The filler rope is made of aramid fiber material. The braided layer is wrapped around the outside of the wrapping layer. The wrapping layer is made of aluminum foil material. The braided layer is made of aramid fiber material. The outer sheath is disposed on the outside of the braided layer.

[0008] Furthermore, the wire core includes a conductor and an insulating layer wrapped around the outside of the conductor, the insulating layer being made of an ethylene-tetrafluoroethylene copolymer material, and the conductor being made of stranded silver-plated copper wire.

[0009] Furthermore, the composite air duct cable also includes a shielding layer, which is disposed between the braided layer and the outer sheath, and the shielding layer is made of silver-plated copper wire.

[0010] Furthermore, the braided shielding density of the shielding layer is greater than 90%.

[0011] Furthermore, the gas duct is made of polytetrafluoroethylene material.

[0012] Furthermore, the outer sheath is made of ethylene-tetrafluoroethylene copolymer material.

[0013] Furthermore, the thickness of the outer sheath is set to 0.2 to 1.5 mm.

[0014] Compared with the prior art, the present invention provides a composite air-conducting cable, comprising a conductor, a filler rope, an air-conducting tube, a wrapping layer, a braided layer, and an outer sheath. The wrapping layer is disposed on the outside of the conductor and the air-conducting tube. The filler rope is filled inside the wrapping layer and disposed in the gap between the conductor and the air-conducting tube. The filler rope is made of aramid fiber material. The braided layer is wrapped around the outside of the wrapping layer and is made of aluminum foil material. The outer sheath is disposed on the outside of the braided layer. By placing the conductor and the air-conducting tube together within the wrapping layer and using the filler rope made of aramid fiber material, the aramid fiber material possesses good flexibility, high strength, and high wear resistance. The tear-resistant properties ensure the roundness of the wires and cables and prevent deformation of the air tube, thereby reducing mutual friction and compression between the air tube and the wires and cables during long-term use. This also improves the tensile strength of the wires and cables, significantly enhancing their tensile resistance. Furthermore, the addition of a braided layer and outer sheath made of aramid fiber on the outside of the wrapping layer further enhances the tensile strength of the wires and cables, protecting the core and air tube. This solves the technical problem of mutual friction and compression between the air tube and the wires and cables during long-term use in existing technologies, reducing the probability of damage to the conductor insulation layer, short circuits, and leakage, increasing the service life of the air tube, and reducing the risk of gas leakage.

[0024] like Figure 1 As shown, this utility model embodiment provides a composite air-conducting cable, including a conductor, a filler rope 400, an air-conducting tube 300, a wrapping layer 500, a braided layer (not shown in the figure), and an outer sheath 700; the wrapping layer 500 is disposed on the outside of the conductor and the air-conducting tube 300, the filler rope 400 is filled inside the wrapping layer 500 and disposed in the gap between the conductor and the air-conducting tube 300, the filler rope 400 is made of aramid fiber material, the braided layer is wrapped around the outside of the wrapping layer 500, the wrapping layer 500 is made of aluminum foil material, the braided layer is made of aramid fiber material, and the outer sheath 700 is disposed on the outside of the braided layer.

[0025] Specifically, the composite gas-conducting cable provided by this utility model sets the core and the gas-conducting tube 300 together within the wrapping layer 500, and uses a filler rope 400 made of aramid filament material. This gives the aramid filament good flexibility, high strength, high wear resistance, and tear resistance, resulting in a rounded cable and preventing the gas-conducting tube 300 from deforming. This reduces mutual friction and compression between the gas tube and the cable during long-term use, while also improving the tensile strength of the cable and greatly enhancing its tensile strength. Furthermore, by providing a braided layer and an outer sheath 700 made of aramid filament material on the outside of the wrapping layer 500, the tensile strength of the cable is further improved, protecting the core and the gas-conducting tube 300. This solves the technical problem of mutual friction and compression between the gas tube and the cable during long-term use in existing technologies, reduces the probability of damage to the conductor insulation layer 200 leading to short circuits and leakage, increases the service life of the gas tube, and reduces the risk of gas leakage.

[0026] Specifically, in this embodiment, three wire cores and the air duct 300 are arranged side by side, and four filler ropes 400 are evenly arranged in the gap between the wire cores and the air duct 300, and are arranged parallel to the wire cores and the air duct 300. The air duct 300 is a hollow circular tube. The wrapping layer 500 uses aluminum foil to wrap the wire cores, air duct 300 and filler ropes 400, which can play a role in shaping, protection and shielding. The filler ropes 400 are made of aramid fiber material. Aramid fiber has good flexibility, high strength, high wear resistance and tear resistance, which makes the cable round, the air duct 300 is not easy to deform, and can improve the tensile strength of the wire and cable, greatly enhancing the tensile strength of the cable. The outer sheath 700 is arranged on the outside of the braided layer, finally forming a composite air duct cable with a circular cross-section.

[0027] Furthermore, the wire core includes a conductor 100 and an insulation layer 200 wrapped around the outside of the conductor 100. The insulation layer 200 is made of ethylene-tetrafluoroethylene copolymer material, and the conductor 100 is made of silver-plated copper wire stranded together.

[0028] Specifically, conductor 100 is made of silver-plated copper wire stranded together. Silver-plated copper wire has excellent electrical conductivity; silver plating improves its conductivity, reduces resistance, and increases transmission efficiency. It also has good thermal conductivity, making it suitable for high-temperature environments. Silver has high thermal conductivity, effectively transferring heat. Silver also has strong oxidation and corrosion resistance; the silver plating layer effectively prevents oxidation and corrosion of the copper wire, extending its service life. In this embodiment, conductor 100 has a cross-sectional area of ​​0.2 mm², and its structure consists of 19 strands of 0.12 mm silver-plated copper wire stranded together. The insulation layer 200 is an ethylene-tetrafluoroethylene copolymer, extruded onto the surface of conductor 100, with a thickness of 0.1–1.0 mm (0.40 mm in this embodiment). The outer diameter of the insulation layer is 1.4 mm. Ethylene-tetrafluoroethylene copolymer has high thermal stability, aging resistance, acid and alkali resistance, and flame retardancy. Furthermore, it has good dielectric strength and insulation resistance, making it ideal for use as an insulation material.

[0029] Furthermore, the composite air duct cable also includes a shielding layer 600, which is disposed between the braided layer and the outer sheath 700, and the shielding layer 600 is made of silver-plated copper wire material.

[0030] Specifically, the shielding layer 600 is woven between the braided layer and the outer sheath 700, and it is made of silver-plated copper wire, thereby playing the role of shielding electromagnetic interference.

[0031] Preferably, the braided shielding density of the shielding layer 600 is greater than 90%.

[0032] Specifically, in this embodiment, the braided shielding density of the shielding layer 600 is set to 92%, thereby ensuring that the shielding layer 600 can achieve a good shielding effect.

[0033] Furthermore, the air duct 300 is made of polytetrafluoroethylene material.

[0034] Specifically, polytetrafluoroethylene (PTFE) has an extremely low coefficient of friction, good chemical corrosion resistance, high temperature stability, and excellent electrical insulation properties. Using PTFE to make the gas conduit 300 can reduce the friction between the gas conduit 300 and the wire core, improve the service life of the gas conduit, and reduce the risk of gas leakage.

[0035] Furthermore, the outer sheath 700 is made of ethylene-tetrafluoroethylene copolymer material.

[0036] Specifically, the outer sheath 700 is made of ethylene-tetrafluoroethylene copolymer material. Ethylene-tetrafluoroethylene copolymer has high thermal stability, aging resistance, acid and alkali resistance, wear resistance and flame retardancy, which can protect the cable from damage, extend the product's lifespan and make it more convenient to use.

[0037] Furthermore, the thickness of the outer sheath 700 is set to 0.2 to 1.5 mm.

[0038] Specifically, in this embodiment, the thickness of the outer sheath 700 is set to 0.9 mm, thereby ensuring that the outer sheath 700 can provide good protection for the internal wire core and braided layer.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
