Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a wear-resistant and waterproof power cable. Background Technology

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer, and are wires that transmit electricity or information from one place to another. With the rapid development of underground power cable laying projects, higher requirements are being placed on cable quality.

[0003] Currently, in many power systems, ordinary cables are used as transmission cables. However, the design of ordinary cables does not take into account the wear and water resistance of the application environment, so their wear and water resistance is insufficient and thus cannot meet the special requirements of users.

[0004] Therefore, those skilled in the art have provided a wear-resistant and waterproof power cable to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the issue of insufficient wear resistance and waterproofing, this utility model provides a wear-resistant and waterproof power cable.

[0006] This utility model provides a wear-resistant and waterproof power cable, which adopts the following technical solution:

[0007] A wear-resistant and waterproof power cable includes a cable core and a shielding layer. The cable core has three sections, which are located inside the shielding layer. An insulation layer is fixedly connected to the outer surface of the cable core. A resilient rubber tube is provided in the inner cavity of the shielding layer between adjacent cable cores. A waterproof layer is fixedly connected to the outer surface of the shielding layer. A functional layer is fixedly connected to the outer surface of the waterproof layer. A wear-resistant layer is fixedly connected to the outer surface of the functional layer.

[0008] By adopting the above technical solutions, the cable core, shielding layer, and insulation layer can improve the insulation and shielding performance of the cable. By setting up a rebound rubber tube, the cable can be buffered and protected when it is squeezed, thus avoiding damage. By setting up a waterproof layer, the cable's waterproof performance can be improved. By setting up a functional layer, the cable's heat insulation and flame retardant performance can be improved. By setting up a wear-resistant layer, the cable's wear resistance can be improved.

[0009] Optionally, the functional layer includes a heat insulation layer, the inner surface of which is fixedly connected to the waterproof layer, and a flame retardant layer is fixedly connected to the outer surface of the heat insulation layer, and the outer surface of the flame retardant layer is fixedly connected to the wear-resistant layer.

[0010] By adopting the above technical solutions, the heat insulation layer can improve the heat insulation performance of the cable, and the flame retardant layer can improve the flame retardant performance of the cable.

[0011] Optionally, the inner cavity of the shielding layer is provided with steel wires, which are located between the three cable cores.

[0012] By adopting the above technical solution, the addition of steel wires can improve the tensile strength of the cable.

[0013] Optionally, the inner surface of the shielding layer is filled with a filler layer, which is tightly fitted at the connection between the filler layer and the steel wire, the resilient rubber tube and the insulating layer.

[0014] By adopting the above technical solution, the filling layer can support the steel wire, the resilient rubber tube and the insulation layer, and at the same time, it can buffer the cable when it is squeezed, thereby effectively improving the cable's heat insulation and buffering performance.

[0015] Optionally, the shielding layer is made of aluminum foil, and the insulating layer is made of polytetrafluoroethylene.

[0016] By adopting the above technical solution, the shielding layer is made of aluminum foil, which has good conductivity and reflectivity, making it particularly suitable for shielding high-frequency electromagnetic interference, thereby improving the shielding performance of the cable. The insulation layer is made of polytetrafluoroethylene (PTFE), which is resistant to high temperature and corrosion, has excellent electrical insulation, aging resistance, and low water absorption, thus effectively improving the insulation effect of the cable.

[0017] Optionally, the waterproof layer is made of PVC coated fabric, and the wear-resistant layer is made of ultra-high molecular weight polyethylene.

[0018] By adopting the above technical solution, the waterproof layer is made of PVC coated fabric. PVC coated fabric has excellent mildew resistance, significant waterproof performance, good low-temperature flexibility, high strength, high tensile strength, and relatively light weight, thus effectively improving the waterproof performance of the cable. The wear-resistant layer is made of ultra-high molecular weight polyethylene. Ultra-high molecular weight polyethylene is a linear thermoplastic engineering plastic with excellent comprehensive performance. Ultra-high molecular weight polyethylene fiber is the third generation of special fiber in the world today, with a strength as high as 30.8 cN / dtex, the highest specific strength among chemical fibers, and good wear resistance, impact resistance, corrosion resistance, and light resistance, thus effectively improving the wear resistance of the cable.

[0019] Optionally, the heat insulation layer is made of ceramic fiber, and the flame retardant layer is made of fireproof fabric.

[0020] By adopting the above technical solution, the insulation layer is made of ceramic fiber, a fibrous, lightweight refractory material with advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. This improves the cable's thermal insulation performance. The flame-retardant layer is made of fire-resistant fabric, which is treated with PROBAN production technology to effectively prevent the spread of flames while protecting the original properties of the fabric, thus effectively improving the cable's fire resistance. In summary, this utility model has the following beneficial effects:

[0021] 1. This utility model improves the insulation and shielding performance of the cable by setting a cable core, a shielding layer, and an insulation layer.
