Description

Technical Field

[0001] This utility model relates to the field of cables, and more specifically, to a high-strength, durable cable. Background Technology

[0002] As a carrier of electrical energy and signal transmission, cables are widely used in many fields such as power, communication, industrial control, and outdoor lighting. In practical applications, cables often need to cope with complex mechanical stress and harsh environmental challenges, such as frequent dragging, long-term bending, strong pulling force, external extrusion, ultraviolet radiation, oil corrosion, and potential fire risks. Therefore, the market demand for special cables that combine high strength and long-term durability is becoming increasingly urgent. For example, patent (CN221946831U) discloses a high-voltage resistant cable that can fill the gaps during stranding to prevent electric arcs under high voltage and improve the high-voltage resistance of the cable. When using the above technology, the following technical problems were found in the existing technology: it is insufficient in weather resistance, oil resistance and flame retardancy, it is prone to aging and becoming brittle after long-term use, and its mechanical strength and wear resistance are poor, making it difficult to withstand continuous friction and impact. Therefore, we designed a high-strength durable cable to provide another technical solution to the above technical problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example:

[0018] Please see Figure 1-5 A high-strength and durable cable includes a cable sheath 1, a plurality of cable cores 3 are disposed inside the cable sheath 1, a central reinforcing member 2 is disposed inside the cable sheath 1 and between the plurality of cable cores 3, an outer sheath 5 is disposed outside the cable sheath 1, and a plurality of reinforcing ribs 4 are evenly distributed inside the cable sheath 1. The cable sheath 1 is made of modified polyvinyl chloride. Modified polyvinyl chloride has excellent rheological properties in the molten state, which can tightly wrap and adhere to the complex central reinforcement 2, cable core 3 and reinforcing rib 4, effectively dispersing external impact force and lateral pressure, and preventing direct damage to internal components. The central reinforcing member 2 is made of glass fiber reinforced plastic rod. Glass fiber reinforced plastic rod has extremely high tensile strength, which can significantly reduce the overall weight of the cable, while providing strong tensile strength. It has very small deformation when under stress, which can effectively maintain the structural shape of the cable and resist long-term tensile stress without plastic deformation. This ensures that the cable will not be excessively elongated or deformed due to its own weight when it is laid vertically or suspended over a long distance. Reinforcing rib 4 is made of polypropylene braided rope. Polypropylene braided rope can greatly reduce the weight of the cable. Its braided structure provides good tensile strength and impact toughness, which is sufficient to cope with the side pressure and torsion problems commonly encountered in cable use. The outer sheath 5 is composed of a first protective layer 51, a second protective layer 52 and a third protective layer 53. The second protective layer 52 is provided on the outside of the first protective layer 51, and the third protective layer 53 is provided on the outside of the second protective layer 52. The first protective layer 51 is made of thermoplastic polyurethane. Thermoplastic polyurethane has extremely high tear resistance, tensile strength and impact resistance. When subjected to tension, compression or sudden impact, it can effectively protect the internal structure from cracking. It is not easy to crack after repeated bending and has an extremely long bending life. The second protective layer 52 is a galvanized steel wire braided mesh. The galvanized steel wire braided mesh is made of high-strength steel wire through a weaving process to form a mesh structure, and is hot-dip galvanized or electro-galvanized on the surface. It can withstand huge tensile forces and prevent the cable from being broken during installation or use. The sturdy mesh structure can effectively resist external squeezing, impact and trampling, and protect the cable core 3 from damage. The third protective layer 53 is made of neoprene rubber. Neoprene rubber has good wear resistance, tear resistance and mechanical strength. It has natural resistance to ultraviolet rays and ozone. When exposed to sunlight for a long time, it will not crack, powder or become sticky like ordinary materials. It has good resistance to various greases, lubricants and chemical reagents. It is flame-retardant rubber that is self-extinguishing when the flame is removed. In the event of a short circuit or external fire source ignition, it will not contribute to the spread of flames, which greatly improves the safety of the cable.

[0019] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
