Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an anti-aging and oil-resistant cable. Background Technology

[0002] During cable manufacturing, oily substances such as lubricants or corrosion inhibitors may be used. These substances may not be completely removed during the wire's manufacturing or storage and may seep out over time. Cable insulation is typically made of plastic or rubber materials, which are highly sensitive to grease and chemicals. If a cable is exposed to oil, the insulation material may swell, soften, or degrade, leading to decreased insulation performance and increasing the risk of short circuits or leakage. Furthermore, prolonged use can cause surface aging, increasing the risk of short circuits and fires. Additionally, the cable's compressive strength decreases during use, making it prone to deformation and rendering it unusable. Therefore, an anti-aging, oil-resistant cable is needed. Utility Model Content

[0003] The present invention aims to address the shortcomings of the prior art by providing an anti-aging and oil-resistant cable.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: an anti-aging oil-resistant cable, comprising: a central reinforcing tube, with multiple sets of conductors spirally wound around the outside of the central reinforcing tube, an outer shielding layer covering the outside of the conductors, a filling layer between the outer shielding layer and the conductors, a metal wire mesh covering the outside of the outer shielding layer, an oil-resistant layer covering the outside of the metal wire mesh, a water-resistant layer covering the outside of the oil-resistant layer, an anti-corrosion layer covering the outside of the water-resistant layer, an anti-aging layer covering the outside of the anti-corrosion layer, and an outer sheath covering the outside of the anti-aging layer.

[0005] Furthermore, the conductor includes a double-stranded core, the double-stranded cores are twisted together, the outer side of the double-stranded cores is covered with an inner shielding layer, and the outer side of the inner shielding layer is covered with an insulating sleeve.

[0006] Furthermore, the filler in the filling layer is flame-retardant glass fiber.

[0007] Furthermore, both the inner and outer shielding layers are extruded aluminum sheaths, and the metal wire mesh is made of tin-plated copper wire.

[0008] Furthermore, the oil-proof layer is made of polyurethane material, the water-proof layer includes water-blocking tape and water-blocking cable paste, and the anti-corrosion layer is made of polyvinyl chloride.

[0009] Furthermore, the anti-aging layer is made of polyolefin synthetic material with added anti-aging agents.

[0010] Furthermore, the outer sheath is an anti-aging halogen-free vulcanized rubber sheath.

[0011] The beneficial effects of this utility model are: it provides triple protection against oil, water, and corrosion, preventing external pollution or oil from the cable material from damaging the insulation layer and affecting the normal use of the cable; it provides double-layer shielding to effectively block interference signals; and it provides an anti-aging layer and an outer sheath to effectively protect the cable from oxidation, thereby further extending the cable's service life. It is highly practical. Attached Figure Description

[0015] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figure 1 As shown, an anti-aging, oil-resistant cable includes: a central reinforcing tube 1, with multiple sets of conductors 2 spirally wound around the outside of the central reinforcing tube 1, an outer shielding layer 3 covering the outside of the conductors 2, a filling layer 4 between the outer shielding layer 3 and the conductors 2, a metal wire mesh 5 covering the outside of the outer shielding layer 3, an oil-resistant layer 6 covering the outside of the metal wire mesh 5, a water-resistant layer 7 covering the outside of the oil-resistant layer 6, an anti-corrosion layer 8 covering the outside of the water-resistant layer 7, an anti-aging layer 9 covering the outside of the anti-corrosion layer 8, and an outer sheath 10 covering the outside of the anti-aging layer 9.

[0018] Specifically, the outer shielding layer 3 completely shields interference signals, preventing interference signals from affecting the conductor 2 and improving signal transmission efficiency.

[0019] The conductor 2 includes a double-strand core 11, the double-strand core 11 is twisted together, the outer side of the double-strand core 11 is covered with an inner shielding layer 12, and the outer side of the inner shielding layer 12 is covered with an insulating sleeve 13.

[0020] Specifically, the inner shielding layer 12 shields the signal of the interfering wire 2, and the insulating sleeve 13 improves the safety of the wire 2 and prevents electric shock.

[0021] The filler of the filling layer 4 is flame-retardant glass fiber.

[0022] Specifically, glass fiber has high tensile strength. Adding flame retardants to glass fiber increases its flame retardant properties, improves the tensile strength of conductor 2, and prevents the conductor from spontaneously combusting due to temperature rise, thus preventing accidents.

[0023] Both the inner shielding layer 12 and the outer shielding layer 3 are extruded aluminum sheaths, and the metal wire mesh 5 is made of tin-plated copper wire.

[0024] Specifically, the metal wire mesh 5 secures the outer shielding layer 3 to prevent it from falling off. The tin-plated copper material is anti-oxidant and rust-proof, which can extend the service life and improve safety.

[0025] The oil-proof layer 6 is made of polyurethane material, the water-proof layer 7 includes water-blocking tape and water-blocking cable paste, and the anti-corrosion layer 8 is made of polyvinyl chloride.

[0026] Specifically, PVC material is resistant to acids and alkalis, preventing internal materials from being corroded; water-blocking tape and water-blocking cable paste can prevent water from entering the cable radially; polyurethane material can achieve oil resistance in harsh working environments, and together with anti-corrosion layer 8, it can further prevent oil stains from penetrating.

[0027] The anti-aging layer 9 is made of polyolefin synthetic material with added anti-aging agents.

[0028] Specifically, polyolefins have the characteristics of low relative density, good chemical resistance, and good water resistance. They also have good mechanical strength and electrical insulation properties. Adding anti-aging agents, which can greatly extend the service life of materials, can further increase the aging resistance of cables.

[0029] The outer sheath 10 is an anti-aging halogen-free vulcanized rubber sheath.

[0030] Specifically, halogen-free vulcanized rubber sheaths effectively improve the oxidation resistance of cables.

[0031] In summary, this utility model provides double-layer shielding by setting the inner shielding layer 12 and the outer shielding layer 3, effectively shielding interference signals; setting the oil-proof layer 6, the water-proof layer 7, and the anti-corrosion layer 8 together prevent the intrusion and corrosion of oil and water; setting the anti-aging layer 9 and the outer sheath 10 provides the cable with effective anti-oxidation protection, thereby further extending the service life of the cable and improving its practicality.

[0032] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
