Description
Technical Field
[0001] This utility model belongs to the field of cable technology, specifically an anti-aging cable structure. Background Technology
[0002] Cables are typically rope-like structures made of several or groups of conductors (at least two conductors per group) twisted together. Each group of conductors is insulated from the others and is often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation. Types of cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single or multiple strands of conductors and an insulation layer, used to connect circuits and electrical appliances. Based on the photovoltaic power station system, cables can be classified as DC cables and AC cables.
[0003] Meanwhile, a new type of anti-aging cable, with application number CN202420900451.X, includes a protective sheath. The inner side of the protective sheath has a filling layer, and the outer surface of the protective sheath is coated with an anti-UV coating. The outer surface of the protective sheath has uniformly distributed first conical grooves. A support column is provided inside the filling layer. Rubber strips are uniformly distributed on the outer surface of the support column. One end of each rubber strip has a trapezoidal rubber block. A cavity is provided inside the rubber strip. A second conical groove is provided in the middle of the rubber strip. A shielding layer is provided on the inner surface of the protective sheath, and a waterproof layer is provided on the inner surface of the shielding layer. An insulating sleeve is uniformly distributed outside the support column. A conductor is provided inside the insulating sleeve. A flexible tube is uniformly distributed between the conductor and the insulating sleeve. A flame-retardant layer is provided on the inner surface of the insulating sleeve. This invention increases the strength of the cable and reduces cable deformation and aging.
[0004] However, the following problems were found in the implementation of the relevant technology: only a single waterproof layer is set to protect the inner core of the cable. However, a single waterproof layer inevitably leads to the need to further improve the waterproof performance of the cable. If the waterproof performance of the cable itself is not good, problems will inevitably occur when the cable is used in a specific humid environment or when the cable is soaked. Utility Model Content
[0005] To address the problems mentioned in the background section, this utility model provides an anti-aging cable structure that has the advantages of improved waterproofing and anti-aging properties of the cable itself.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

The staggered first inner support strip and the second inner support strip mutually support each other, relieving the external pressure on the inner core and protecting it.

[0018] 2. This utility model prevents water seepage into the cable core through the vacuum effect of the vacuum layer, which not only waterproofs the cable but also improves the overall anti-aging properties of the cable core. Furthermore, the waterproof effect of the inner waterproof sleeve and the flame-retardant effect of the inner flame-retardant braided layer both protect the cable core, thus enhancing its anti-aging effect and preventing damage to the cable core that could affect its service life. The shielding layer and the outer cable protective sleeve provide the outermost layer of protection, and multiple wear-resistant protrusions are provided on the surface of the outer cable protective sleeve, thereby reducing wear and increasing the friction during cable installation.

[0030] The surface of the waterproof component 2 is connected to the outer side of the counterweight steel strip layer 5 to improve the waterproofness of the cable.
[0031] The surface of the anti-aging component 3 is connected to the surface of the waterproof component 2 to improve the anti-aging properties of the cable.
[0032] Specifically, the waterproof component 2 includes an insulating layer 21, a plurality of first inner support strips 23 and a plurality of second inner support strips 24. The insulating layer 21 is disposed on the outside of the counterweight steel strip layer 5. A water-blocking layer 22 is connected to the outside of the insulating layer 21. Each first inner support strip 23 is disposed on the surface of the water-blocking layer 22. The surface of each second inner support strip 24 is connected to the surface of the corresponding first inner support strip 23. A corrosion-resistant layer 25 is connected to the surface of the plurality of second inner support strips 24.
[0033] Furthermore, each of the first inner support strip 23 and each of the second inner support strip 24 is made of silicone.
[0034] Furthermore, a plurality of the first inner support bars 23 are arranged in a ring on the surface of the water-blocking layer 22, and a plurality of the second inner support bars 24 are arranged in a ring on the inner side of the corrosion-resistant layer 25.
[0035] It is worth noting that the anti-aging component 3 includes a vacuum layer 31, an inner flame-retardant braided layer 33, and an outer cable protective sleeve 35. The vacuum layer 31 is disposed on the outside of the corrosion-resistant layer 25, and an inner waterproof sleeve 32 is connected to the inside of the vacuum layer 31. The inner flame-retardant braided layer 33 is disposed on the outside of the inner waterproof sleeve 32. A shielding layer 34 is connected to the outside of the vacuum layer 31, and the outer cable protective sleeve 35 is disposed on the outside of the shielding layer 34. A plurality of wear-resistant protrusions 36 are connected to the surface of the outer cable protective sleeve 35.
[0036] It is worth noting that the surface of the inner flame-retardant braided layer 33 is connected to the inner side of the vacuum layer 31.
[0037] It is worth mentioning that the shielding layer 34 is a metal wire mesh shielding layer.
[0038] It is worth emphasizing that the outer cable protective sleeve 35 is made of silicone.
[0039] Among them, the water-blocking layer 22 and the shielding layer 34 are existing technologies and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.
[0040] Working principle: First, an insulation layer 21 and a water-blocking layer 22 are provided on the outer layer of the cable core 1. Therefore, the insulation layer 21 provides insulation and the water-blocking layer 22 provides initial protection for the cable core 1, thus preventing or delaying its aging. A first inner support strip 23 is provided on the surface of the water-blocking layer 22. The first inner support strip 23 and the second inner support strip 24 are interleaved. Therefore, the support provided by the first inner support strip 23 and the second inner support strip 24 alleviates the external compressive force on the cable core 1, thus protecting it. The corrosion-resistant layer 25 has good corrosion resistance, improving the overall corrosion resistance of the cable core 1. Then, a vacuum layer 31 is provided on the surface of the corrosion-resistant layer 25. The vacuum layer 31 prevents water seepage into the cable core 1, thus improving its overall anti-aging properties. An inner waterproof sleeve 32 and an inner flame-retardant braided layer 33 are installed inside the vacuum layer 31. Therefore, in conjunction with the vacuum effect of the vacuum layer 31, the waterproof and flame-retardant effects further protect the cable core 1, enhancing its anti-aging properties and preventing damage that could affect its lifespan. The shielding layer 34 and the outer cable protective sleeve 35 provide the outermost layer of protection. Multiple wear-resistant protrusions 36 are provided on the surface of the outer cable protective sleeve 35, thus reducing wear and increasing the friction during cable installation.
