Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an impact-resistant reinforced armored power cable. Background Art

[0002] Impact-reinforced armored power cable is a cable used for power transmission and distribution, which is designed to provide additional impact protection and structural strength. This type of cable is usually used in places where it needs to operate under harsh conditions or is subject to external impact and crushing risks, such as industrial areas, construction sites or underground layouts.

[0003] After searching, the publication number: CN220324215U discloses an impact-resistant and moisture-proof reinforced armored shipboard power cable, which includes three power cores, one ground core and two polyethylene resin core strips twisted together with polypropylene moisture-absorbing filling core material to form a cable core. The cable core is coated with a fluororubber moisture-proof layer, a butyl rubber water-blocking and pressure-reducing layer, an impact-resistant plain woven mesh armor layer, a polyvinyl chloride inner sheath layer, a nylon wire anti-twist wrapping layer and a polyvinyl chloride outer sheath layer in sequence. The power core includes an inner conductor, an EVA water-blocking adhesive layer, a polyvinyl chloride insulation layer and a nylon resin moisture-proof dielectric layer. The impact-resistant plain woven mesh armor layer includes an inner and outer layer of tinned copper wire plain woven mesh, the inner layer is a flat woven mesh structure formed by weaving fine tinned copper wire, and the outer layer is a flat woven mesh structure formed by weaving coarse tinned copper wire. The diameter of the coarse tinned copper wire is 5 to 20 times that of the fine tinned copper wire. The power cable has excellent moisture-proof performance, better impact resistance, enhanced safety and reliability, and durable use. However, this patent only solves the problem of having excellent moisture-proof performance, better impact resistance and enhanced safety and reliability, but does not solve the problem that the cable's impact-resistant plain woven mesh armor layer is only a combination of inner and outer layers of tinned copper wire plain woven mesh, which leads to the cable being unable to protect the internal wire core well when it is impacted and squeezed, causing the wire core to be squeezed, damaged or even short-circuited.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an impact-resistant reinforced armored power cable, comprising an impact-resistant reinforced armor layer 1, the impact-resistant reinforced armor layer 1 comprises a wear-resistant layer 2, an impact-resistant mesh layer 3 and a nylon mesh layer 4, the inner wall of the wear-resistant layer 2 is bonded with the impact-resistant mesh layer 3, the inner wall of the impact-resistant mesh layer 3 is bonded with the nylon mesh layer 4, the inner wall of the nylon mesh layer 4 is provided with a shielding component, the inner wall of the shielding component is bonded with an impact-resistant layer 6, a cable body 7 is provided inside the impact-resistant layer 6, the shielding component comprises a shielding layer 5, the outer wall of the shielding layer 5 is bonded to the inner wall of the nylon mesh layer 4, and the inner wall of the shielding layer 5 is bonded to the outer wall of the impact-resistant layer 6;

[0038] Specifically, the impact-resistant reinforced armor layer 1 is an important part of cable protection. It is carefully designed and combined by a three-layer structure to provide the best protection and performance. The three-layer structure includes a wear-resistant layer 2, an impact-resistant mesh layer 3 and a nylon mesh layer 4, each of which has unique functions and characteristics. The wear-resistant layer 2 is the first line of defense of the cable and plays a role in protecting the cable as a whole. It is made of a high-performance material such as polyurethane, which is known for its excellent elasticity and wear resistance. This wear-resistant layer 2 can effectively resist the wear and friction of the external environment, thereby extending the service life of the cable. The impact-resistant mesh layer 3 is located behind the wear-resistant layer 2. It is made of polyester fiber and has the characteristics of lightweight, high strength and wear resistance. This mesh layer can effectively absorb and disperse external impact forces and provide good impact protection for the cable. Whether in transportation, installation or use, it can effectively reduce the damage of external impact to the cable body 7. As the last layer of protection, the nylon mesh layer 4 has a very high tensile strength. This mesh layer can effectively enhance the tensile strength of the cable and prevent the cable from breaking or breaking when subjected to tension. The excellent performance of nylon material makes this layer play a vital role in protecting the integrity and stability of the cable. Between the cable body 7 and the impact-resistant reinforced armor layer 1, an impact-resistant layer 6 is filled. This impact-resistant layer 6 is composed of a non-Newtonian fluid and has unique physical properties. When subjected to external impact, it can flow quickly and disperse the impact force, thereby reducing the pressure on the cable body 7. The design of this non-Newtonian fluid enables the cable to better maintain its integrity and stability when subjected to impact. In addition, in order to prevent leakage of the impact-resistant layer 6, a shielding layer 5 is provided between the impact-resistant layer 6 and the nylon mesh layer 4. This shielding layer 5 can effectively seal the impact-resistant layer 6 to prevent it from leaking under external pressure. The presence of the shielding layer 5 not only enhances the overall structural strength of the cable, but also improves the durability and reliability of the cable. In summary, the impact-resistant reinforced armor layer 1 provides comprehensive protection and enhancement for the cable through the combination of the wear-resistant layer 2, the impact-resistant mesh layer 3 and the nylon mesh layer 4, as well as the arrangement of the impact-resistant layer 6 and the shielding layer 5.

[0039] Reference Figure 3 , an inner insulating sleeve 8 is arranged inside the cable body 7, a tensile reinforcement rope 12 is fixedly connected inside the inner insulating sleeve 8, a polymer filling layer 13 is arranged on the inner wall of the inner insulating sleeve 8, a wire core body 9 is arranged inside the polymer filling layer 13, an inner insulating layer 10 is arranged inside the wire core body 9, a conductor 11 is arranged on the inner wall of the inner insulating layer 10, the tensile reinforcement ropes 12 are arranged in a ring array and fixedly connected inside the inner insulating sleeve 8, a grounding wire 14 is arranged inside the polymer filling layer 13, and the diameter of the tensile reinforcement rope 12 is smaller than the thickness of the inner insulating sleeve 8;

[0040] Specifically, the cable body 7 is cleverly arranged inside the impact-resistant layer 6. This design enables the cable to be effectively buffered and protected when it is impacted by the outside world. The impact-resistant layer 6 is made of special materials, has excellent impact resistance and wear resistance, and can effectively absorb and disperse external impact force, thereby protecting the cable body 7 from damage. In order to further improve the insulation performance and stability of the cable, the inner insulating sleeve 8 is used to isolate the impact-resistant layer 6 from the core body 9. The inner insulating sleeve 8 not only has good insulation performance, but also has adhesion and flexibility, and can fit tightly on the surface of the core body 9 to fill the gaps between the conductors. In this way, not only moisture and other external substances are prevented from entering the interior of the cable, but also the stability and safety of the core body 9 inside the inner insulating sleeve 8 are ensured. Inside the core body 9, the polymer filling layer 13 plays an important role in filling and positioning. Through the filling of the polymer filling layer 13, the core body 9 is effectively fixed and supported, preventing it from being misplaced and entangled in the inner insulating sleeve 8. This design not only improves the stability of the core body 9, but also enhances the tensile strength of the cable as a whole. It is worth mentioning that the inner insulating sleeve 8 is also provided with tensile reinforcement ropes 12 arranged in a circular array. These tensile reinforcement ropes 12 are made of high-strength materials and have excellent tensile properties. Their presence greatly improves the tensile strength of the cable as a whole, so that the cable can better maintain its structural integrity and stability when subjected to tension. Finally, the conductor 11 and the polymer filling layer 13 are isolated and insulated by the inner insulating layer 10. The inner insulating layer 10 is made of high-quality insulating material and has excellent insulation and voltage resistance, which ensures the electrical isolation between the conductor 11 and the polymer filling layer 13 and prevents the occurrence of electrical faults.

[0041] Working principle: When using the impact-resistant reinforced armored power cable, the impact-resistant reinforced armor layer 1 is composed of a wear-resistant layer 2, an impact-resistant mesh layer 3 and a nylon mesh layer 4. The wear-resistant layer 2 protects the cable as a whole. The wear-resistant layer 2 is made of polyurethane, which is an elastic and wear-resistant material. The impact-resistant mesh layer 3 is made of polyester fiber, which has the characteristics of light weight, high strength and wear resistance, and can provide good impact protection. The nylon mesh layer 4 has high tensile strength and can effectively enhance the tensile resistance of the cable. The impact-resistant layer 6 filled between the cable body 7 and the impact-resistant reinforced armor layer 1 is a non-Newtonian fluid. A shielding layer 5 is arranged between the impact-resistant layer 6 and the nylon mesh layer 4 to prevent leakage of the impact-resistant layer 6. 6 can offset the impact generated by the outside and reduce the pressure on the core body 9. The cable body 7 is arranged inside the impact-resistant layer 6. The inner insulating sleeve 8 is used to isolate the impact-resistant layer 6 from the core body 9. The core body 9 is filled and positioned inside the inner insulating sleeve 8 by a polymer filling layer 13 to prevent the core body 9 from being misplaced and entangled in the inner insulating sleeve 8, and can also improve the protection of the core body 9. The inner insulating sleeve 8 has good adhesion and flexibility, can fill the gaps between the conductors, and can prevent moisture and other external substances from entering the cable. The tensile reinforcement ropes 12 arranged in a ring array inside the inner insulating sleeve 8 can improve the overall tensile strength of the cable. The conductor 11 and the polymer filling layer 13 are isolated and insulated by the inner insulating layer 10.
