Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a wear-resistant carbon fiber composite core cable. Background Technology

[0002] With the rapid development of the power industry, the requirements for cable performance are increasing. In many application scenarios, such as harsh environments like mines and construction sites, cables need to have good abrasion resistance to ensure long-term stable operation. Traditional cable cores are mostly made of metal, which, while having good conductivity, has certain limitations in abrasion resistance. They are easily damaged by external friction and compression, leading to a shortened cable life and increased maintenance costs. At the same time, metal core cables are heavier, requiring more manpower and resources for installation and laying. Utility Model Content

[0003] In view of the problems existing in the above-mentioned wear-resistant carbon fiber composite core cables, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a wear-resistant carbon fiber composite core cable, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wear-resistant carbon fiber composite core cable includes a cable body and a core. The core is located at the center of the cable body. The core is composed of multiple carbon fiber bundles and filler material between the carbon fiber bundles. An inner insulation layer is tightly wrapped around the core. An outer insulation layer is sleeved on the outside of the inner insulation layer. A protective layer is provided on the outside. The protective layer is composed of a buffer layer, a wear-resistant fiber layer and a wear-resistant rubber layer, which are sleeved sequentially from the inside to the outside.

[0007] Preferably, the filler material is polypropylene.

[0008] Preferably, the buffer layer consists of multiple nitrile rubber strips arranged in a circular array.

[0009] Preferably, the wear-resistant fiber layer is woven from high-strength aramid fibers.

[0010] Preferably, the wear-resistant rubber layer is a styrene-butadiene rubber sleeve.

[0011] Preferably, the inner insulation layer is a cross-linked polyethylene sleeve.

[0012] Preferably, the outer insulation layer is an ethylene propylene rubber sleeve.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model uses carbon fiber bundles as the main component of the wire core. Carbon fiber bundles themselves have the characteristics of high strength and low density. Compared with traditional metal core wires, they significantly reduce the weight of the cable. During installation and laying, they can greatly reduce the consumption of manpower and material resources and improve construction efficiency.

[0015] 2. This utility model, through a unique protective layer design, features a buffer layer composed of multiple nitrile rubber strips arranged in a ring array. When the cable is subjected to external impact, these rubber strips can effectively disperse and absorb the impact force, reducing damage to the internal structure of the cable. The wear-resistant fiber layer is woven from high-strength aramid fibers, which have excellent wear resistance and tear resistance, effectively resisting external friction and scratches. The outermost styrene-butadiene rubber sheath not only further enhances the wear resistance but also has waterproof and moisture-proof functions, preventing moisture and humidity from penetrating the cable's interior, ensuring stable cable operation, and significantly extending the cable's service life in harsh environments.

[0016] 3. In this utility model, polypropylene is selected as the filler material. Its good tensile strength and modulus not only enhance the mechanical properties of the wire core, but also assist in conductivity and play a stabilizing and protective role for the carbon fiber bundle. The inner insulation layer is made of cross-linked polyethylene sheath and the outer insulation layer is made of ethylene propylene rubber sheath. The double insulation design provides reliable insulation performance, effectively prevents leakage, and ensures the safety and stability of power transmission. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a wear-resistant carbon fiber composite core cable.

[0024] Reference Figure 1-2 A wear-resistant carbon fiber composite core cable includes a cable body 1 and a core 2. The core 2 is located at the center of the cable body 1 and is composed of multiple carbon fiber bundles and filler material between the carbon fiber bundles. An inner insulation layer 3 is tightly wrapped around the core 2, and an outer insulation layer 4 is sleeved on the outside of the inner insulation layer 3. A protective layer is provided on the outside of the outer insulation layer 4. The protective layer is composed of a buffer layer 5, a wear-resistant fiber layer 6, and a wear-resistant rubber layer 7, which are arranged sequentially from the inside to the outside. The buffer layer 5 is composed of multiple nitrile rubber strips arranged in a ring array, which can effectively absorb external impact and reduce damage to the internal structure. The wear-resistant fiber layer 6 is woven from high-strength aramid fibers and has extremely high wear resistance and tear resistance, which can effectively resist external friction and scratches. The wear-resistant rubber layer 7 is a styrene-butadiene rubber sheath, which further enhances the wear resistance of the cable and also plays a role in waterproofing and moisture-proofing.

[0025] Reference Figure 1-2 The filler material, polypropylene, possesses excellent tensile strength and modulus, providing the cable with good mechanical and electrical properties. The filler material is inserted between the carbon fiber bundles, serving to fix and protect the carbon fiber bundles while enhancing the overall stability of the core wire.

[0026] Reference Figure 1-2 The inner insulation layer 3 is a cross-linked polyethylene sheath to prevent leakage between the conductor core 2 and the external conductor, ensuring the safe operation of the cable. The outer insulation layer 4 is an ethylene propylene rubber sheath to further enhance the insulation performance of the cable.

[0027] In this invention, during use, a suitable high-wear-resistant carbon fiber composite core cable of appropriate specifications is selected based on actual power transmission requirements. During installation, the cable's light weight reduces the labor intensity of installers and facilitates laying. When the cable is laid in harsh environments such as mines or construction sites, if it is impacted by external objects, the nitrile rubber strip in the buffer layer (5) will elastically deform, absorbing the impact force and preventing it from directly affecting the internal structures of the cable (2 core, 3 inner insulation layer, 4 outer insulation layer, etc.), thus protecting the internal components of the cable. During cable use, if friction occurs with other objects, the wear-resistant fiber layer (6)... High-strength aramid fibers, with their excellent abrasion resistance, resist friction and prevent the cable sheath from being easily worn through. Meanwhile, the abrasion-resistant rubber layer further distributes friction, and its waterproof and moisture-proof properties prevent moisture from penetrating the cable, avoiding moisture affecting the conductivity of the core and ensuring stable power transmission. When the cable requires maintenance or replacement, its reasonable structural design, with each layer relatively independent yet tightly integrated, facilitates inspection and repair. If the outer protective layer is damaged, the corresponding parts, such as the buffer layer (5), abrasion-resistant fiber layer (6), and abrasion-resistant rubber layer (7), can be repaired or replaced according to the actual situation, reducing maintenance costs.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
