Technical Field
[0001] This utility model relates to the field of ADSS optical cable protection technology, and in particular to a short-span enhanced ADSS optical cable. Background Technology
[0002] ADSS optical cable is a special type of optical cable used for power communication, providing a fast and economical transmission channel in power communication systems. After being laid, ADSS optical cable is easily gnawed by rodents. Over time, the outer shell of ADSS optical cable will be chewed open or directly bitten through, seriously endangering the safety of ADSS optical cable use.
[0003] Existing rodent-proof measures for ADSS optical cables generally involve adding a layer of additives such as capsaicin. However, these additives have poor weather resistance and a short lifespan, which is not conducive to the long-term use of ADSS optical cables. Utility Model Content
[0004] Therefore, it is necessary to address the existing rodent-proofing measures for ADSS optical cables, which generally involve adding an additive layer such as capsaicin. However, the additive layer has poor weather resistance and a short lifespan, which is not conducive to the long-term use of ADSS optical cables. Therefore, a short-span enhanced ADSS optical cable should be provided.
[0005] A short-span enhanced ADSS optical cable includes: an ADSS optical cable body, comprising a water-blocking yarn braided rod, a fiber rod, and an optical cable assembly arranged sequentially from the inside and outside, wherein the optical cable assembly and the two fiber rods are arranged in a triangle, and the water-blocking yarn braided rod is disposed between the optical cable assembly and the two fiber rods;
[0006] A water-blocking yarn layer is disposed on the surface of the optical cable assembly and the two fiber rods. A protective layer is sleeved on the surface of the water-blocking yarn layer. The protective layer includes a corrugated steel strip surrounding the surface of the water-blocking yarn layer, and tear cords are embedded in the corrugated steel strip.
[0007] A protective component is disposed on the surface of the corrugated steel strip to protect multiple internal components.
[0008] In one embodiment, the surface of the optical cable assembly and the two fiber rods is provided with a core filling layer, which is disposed inside the water-blocking yarn layer.
[0009] In one embodiment, the optical cable assembly includes a loose tube located inside the cable core filling layer, the loose tube having a plurality of optical fibers disposed therein, and fiber grease being disposed between the plurality of optical fibers and the loose tube.
[0010] In one embodiment, the corrugated steel strip is a longitudinal structure that wraps around the surface of the water-blocking yarn layer, and one end of the tear rope is located inside the corrugated steel strip.
[0011] In one embodiment, the water-blocking yarn layer has an insulating coating on the side near the corrugated steel strip, and the surface of the corrugated steel strip has an anti-oxidation layer.
[0012] In one embodiment, the protective component includes a first protective layer sleeved on the surface of the corrugated steel strip, a second protective layer sleeved on the surface of the first protective layer, and a plurality of reinforcing ribs provided between the first protective layer and the second protective layer, the plurality of reinforcing ribs being circumferentially wound around the surface of the first protective layer.
[0013] In one embodiment, a cavity is formed between multiple second protective layers, and multiple limiting blocks are provided inside the second protective layers, with both sides of the multiple limiting blocks being fixedly connected to the reinforcing ribs.
[0014] Beneficial effects
[0015] 1. The water-blocking yarn braided rod and water-blocking yarn layer improve the moisture-proof and waterproof effect of the ADSS optical cable body. The water-blocking yarn layer supports the corrugated steel strip. The fiber rod is lightweight and has high mechanical strength, which can make the ADSS optical cable body lightweight while increasing its mechanical strength. The protective layer improves the mechanical strength of the ADSS optical cable body through the surrounding corrugated steel strip. It can also protect the outside and effectively reduce the gnawing of rodents such as rats and moles in the long term, thus improving the safety of the ADSS optical cable body in use.
[0016] 2. The protective component is made of materials such as low-smoke halogen-free material sheath, polyethylene sheath, and polyvinyl chloride. The first and second protective layers are supported by reinforcing ribs. Multiple reinforcing ribs are wrapped in a ring around the surface of the first protective layer, forming multiple annular cavities between the multiple annular reinforcing ribs. The cavities can reduce the weight of the protective component and buffer the protective component, protecting the internal optical cable assembly. Multiple limiting blocks further support the multiple cavities, improving the structural strength of the cavities, while making the reinforcing ribs less prone to deformation, improving the stability of the cavities, and improving the buffering capacity of the protective component.

[0029] The following is combined with Figures 1-4 This invention describes a small-span enhanced ADSS optical cable.
[0030] In one embodiment, a small-span enhanced ADSS optical cable includes: an ADSS optical cable body 100, a water-blocking yarn layer 105, and a protective component 107. The cable includes a water-blocking yarn braided rod 101, fiber rods 102, and an optical cable assembly 103 arranged sequentially from the inside out. The optical cable assembly 103 and the two fiber rods 102 are arranged in a triangle. The water-blocking yarn braided rod 101 is disposed between the optical cable assembly 103 and the two fiber rods 102. The water-blocking yarn layer 105 is disposed on the surface of the optical cable assembly 103 and the two fiber rods 102. A protective layer 106 is sleeved on the surface of the water-blocking yarn layer 105. The protective layer 106 includes a corrugated steel strip 1061 surrounding the surface of the water-blocking yarn layer 105. Tear cords 1062 are embedded in the corrugated steel strip 1061. The protective component 107 is disposed on the surface of the corrugated steel strip 1061 to protect multiple internal components.
[0031] In this embodiment, the triangular arrangement of the optical cable assembly 103 and the two fiber rods 102 can improve the structural strength of the optical cable assembly 103, and the fiber rods 102 can reduce the overall mass of the ADSS optical cable body 100 and increase the structural strength of the ADSS optical cable body 100, making the optical cable assembly 103 less prone to bending.
[0032] The water-blocking yarn braiding rod 101 is a key equipment component used in the manufacture of water-blocking yarn, belonging to the field of textile machinery. Its core function is to combine water-blocking fibers such as aramid and high-density polyethylene with reinforcing materials such as glass fiber and carbon fiber through precision braiding technology to form yarn with water-blocking, tensile strength, and corrosion resistance properties. The water-blocking yarn braiding rod 101 improves the structural strength of the ADSS optical cable body 100 axis.
[0033] The water-blocking yarn braided rod 101 and the water-blocking yarn layer 105 improve the moisture-proof and waterproof effect of the ADSS optical cable body 100. The water-blocking yarn layer 105 supports the corrugated steel tape 1061. The fiber rod 102 is lightweight and has high mechanical strength, which can make the ADSS optical cable body 100 lighter while increasing its mechanical strength. The protective layer 106 improves the mechanical strength of the ADSS optical cable body 100 through the surrounding corrugated steel tape 1061, and can also protect the outside. It can effectively reduce the gnawing of rodents such as rats and moles in the long term, and improve the safety of the ADSS optical cable body 100 in use.
[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the surface of the optical cable assembly 103 and the two fiber rods 102 is provided with a core filling layer 104. The core filling layer 104 is located inside the water-blocking yarn layer 105. The optical cable assembly 103 includes a loose tube 1031 located inside the core filling layer 104. A plurality of optical fibers 1032 are provided inside the loose tube 1031. Fiber jelly 1033 is provided between the plurality of optical fibers 1032 and the loose tube 1031.
[0035] In this embodiment, the core filling layer 104 is used to limit and support the optical cable assembly 103 and the two fiber rods 102, while improving the buffering capacity and the safety of the optical cable assembly 103 during use. The loose tube 1031 protects the internal fiber grease 1033, which limits and protects the multiple optical fibers 1032, increasing the safety of the optical fibers 1032 during use.
[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the corrugated steel strip 1061 has a longitudinal structure that wraps around the surface of the water-blocking yarn layer 105. One end of the tear rope 1062 is inserted inside the corrugated steel strip 1061. The water-blocking yarn layer 105 is provided with an insulating coating on the side near the corrugated steel strip 1061. The surface of the corrugated steel strip 1061 is provided with an anti-oxidation layer.
[0037] In this embodiment, the corrugated steel strip 1061 forms an armored structure through ring-wound, which can effectively reduce the chewing of external animals. During installation, a tear cord 1062 is inserted into the ring-shaped corrugated steel strip 1061. The tear cord 1062 improves the structural strength and stability of the ring-shaped corrugated steel strip 1061 during the winding process. The tear cord 1062, also known as binding rope or tear tape, is a high-performance industrial consumable made of materials such as polypropylene, nylon, aramid, or polyester fiber, specifically designed for rapid tearing, disassembly, or auxiliary operation. Its core function is to achieve efficient and controllable tearing through pre-set tear lines, cuts, or mesh structures, and it is widely used in packaging, logistics, power communication, construction, and industrial manufacturing.
[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the protective component 107 includes a first protective layer 1071 sleeved on the surface of the corrugated steel strip 1061, a second protective layer 1072 sleeved on the surface of the first protective layer 1071, a plurality of reinforcing ribs 1073 provided between the first protective layer 1071 and the second protective layer 1072, the plurality of reinforcing ribs 1073 being wrapped in a ring around the surface of the first protective layer 1071, a cavity being formed between the plurality of second protective layers 1072, a plurality of limiting blocks 1074 provided inside the second protective layer 1072, and the two sides of the plurality of limiting blocks 1074 being fixedly connected to the reinforcing ribs 1073 respectively;
[0039] In this embodiment, the protective component 107 is made of materials such as low-smoke halogen-free material sheath, polyethylene sheath, and polyvinyl chloride. The first protective layer 1071 and the second protective layer 1072 are supported by reinforcing ribs 1073. Multiple reinforcing ribs 1073 are wrapped in a ring around the surface of the first protective layer 1071, forming multiple annular cavities between the multiple annular reinforcing ribs 1073. The cavities can reduce the weight of the protective component 107 and buffer the protective component 107, protecting the internal optical cable assembly 103. Multiple limiting blocks 1074 further support the multiple cavities, improving the structural strength of the cavities, while making the reinforcing ribs 1073 less prone to deformation, improving the stability of the cavities, and improving the buffering capacity of the protective component 107.
[0040] Working principle:
[0041] The water-blocking yarn braided rod 101 and the water-blocking yarn layer 105 improve the moisture-proof and waterproof effect of the ADSS optical cable body 100. The water-blocking yarn layer 105 supports the corrugated steel tape 1061. The fiber rod 102 is lightweight and has high mechanical strength, which can make the ADSS optical cable body 100 lighter while increasing its mechanical strength. The protective layer 106 improves the mechanical strength of the ADSS optical cable body 100 through the surrounding corrugated steel tape 1061, and can also protect the outside. It can effectively reduce the gnawing of rodents such as rats and moles in the long term, and improve the safety of the ADSS optical cable body 100 in use.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
