Description

Technical Field

[0001] The utility model relates to the technical field of copper wire sheathing materials, and particularly relates to a corrosion-resistant semi-conductive copper wire sheathing material. Background Art

[0002] The semi-conductive copper wire sheathing material is a special material combination used to protect and optimize the performance of copper wires. It usually consists of multiple layers, including a semi-conductive layer, an insulating layer, a corrosion-resistant layer, a reinforcing layer, and an outer sheath, etc. The sheathing material can provide good insulation performance, prevent current leakage and short circuits, and ensure the safety and stability of power transmission. Without the protection of the sheathing material, the semi-conductive copper wire is prone to contact with external conductive substances, leading to electrical accidents.

[0003] In some high-temperature environments, the sheathing material may experience a decline in performance, softening, or even deformation, affecting its insulation and protection effects. After softening, the connection between the inner layer structure of the sheathing material and the inner copper wire may easily become detached from the original connection relationship. Under extreme conditions, such as strong impacts or continuous high pressures, the sheathing material may be damaged or fractured. A strong impact may instantaneously generate a huge force that exceeds the bearing limit of the sheathing material, causing its structure to collapse. Continuous high pressure will gradually accumulate damage, resulting in tiny cracks inside the sheathing material. These cracks will continuously expand under long-term action, ultimately leading to the fracture of the sheathing material. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the sheathing material is prone to softening, which may cause the detachment of the inner layer structure from the inner copper wire, and the sheathing material is prone to damage or fracture. The utility model provides a corrosion-resistant semi-conductive copper wire sheathing material.

[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:

[0006] A corrosion-resistant semi-conductive copper wire sheathing material includes a semi-conductive layer. The semi-conductive layer includes inner convex particles, and the inner side of the inner convex particles is directly in contact with the internal copper wire inside. The outer layer of the semi-conductive layer is covered with an insulating layer, and the outer layer of the insulating layer is covered with a corrosion-resistant layer. The internal part of the insulating layer is penetrated and connected with a reinforcing layer. The reinforcing layer includes reinforcing filaments, and the side walls of the reinforcing filaments are distributed inside the insulating layer. The outer layer of the corrosion-resistant layer is covered with an outer sheath. The outer sheath includes a repair layer, and the innermost layer of the repair layer is distributed around the innermost layer of the outer sheath, and the repair layer extends outward along the side wall of the outer sheath.

[0007] Furthermore, the semiconductive layer further includes a collar and indentations. The outer side of the collar penetrates through the inner sidewall of the insulating layer, and the indentations are clamped inside the insulating layer. In the case where the wire moves frequently or is in a vibrating environment, the collar can limit the sliding of the semiconductive layer within the insulating layer, while the indentations can further enhance this limiting effect.

[0008] Furthermore, the inner convex grains are arranged inside the collar, and the indentations are arranged on the outer ring of the collar. Their protruding forms form a tight fitting relationship with the surrounding structures.

[0009] Furthermore, the reinforcing layer further includes a braided wire mesh. The sidewalls of the reinforcing wires and the braided wire mesh penetrate through the inner side of the insulating layer, providing strong tensile and compressive capabilities for the entire structure. When the wire is subjected to external tensile or compressive forces, the reinforcing wires can effectively bear and disperse these stresses, preventing the wire from deforming or breaking.

[0010] Furthermore, the braided wire mesh and the sidewalls of the reinforcing wires are connected in a spaced-apart manner, distributing the remaining forces evenly throughout the structure, thereby avoiding structural damage caused by excessive local stress.

[0011] Furthermore, the outer sheath further includes a protective layer, an anti-aging layer, and a waterproof layer. The innermost layer of the repair layer is distributed around the innermost layers of the protective layer and the anti-aging layer and extends to the outside thereof. The inner layer of the protective layer is sleeved outside the corrosion-resistant layer, ensuring the integrity of the entire sheath under harsh usage conditions.

[0012] Furthermore, the inner side of the anti-aging layer is sleeved outside the protective layer, the inner side of the waterproof layer is sleeved outside the anti-aging layer, and the repair layer extends from the inner side of the anti-aging layer to the inner side of the waterproof layer. The anti-aging layer is closely attached to the outside of the protective layer, providing additional protection for it.

[0013] Compared with the prior art, the present utility model provides a corrosion-resistant semiconductive copper wire sheath, having the following beneficial effects:

[0014] This corrosion-resistant semi-conductive copper wire sheath material, when viewed through the semi-conductive layer, is in close contact with the copper wire, which helps to evenly distribute the electric field, reduce local electric field concentration. The insulating layer can effectively block the current, prevent leakage and short circuits, ensuring electrical safety. The reinforcing filaments and braided wire mesh structure in the reinforcing layer greatly improve the mechanical strength of the sheath material, can maintain the structural integrity of the wire, and is not prone to deformation and fracture. The protective layer in the outer sheath can resist external physical abrasion and impact, reducing direct damage to the internal structure by external factors. The various layer structures of this corrosion-resistant semi-conductive copper wire sheath material cooperate with each other to jointly achieve the goals of improving power transmission efficiency, ensuring electrical safety, enhancing mechanical strength, resisting corrosion and environmental impacts, and extending service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment 1:

[0022] As Figures 1 - 5As shown in the figure, a corrosion-resistant semi-conductive copper wire sheath material includes a semi-conductive layer 1. The semi-conductive layer 1 includes inner convex particles 12, and the inner side of the inner convex particles 12 is in direct contact with the internal copper wire. The outer layer of the semi-conductive layer 1 is covered with an insulating layer 2, the outer layer of the insulating layer 2 is covered with a corrosion-resistant layer 3, an enhancement layer 4 is connected through the interior of the insulating layer 2. The enhancement layer 4 includes enhancement filaments 41, and the side walls of the enhancement filaments 41 are distributed inside the insulating layer 2. The outer layer of the corrosion-resistant layer 3 is covered with an outer sheath 5. The outer sheath 5 includes a repair layer 54. The innermost layer of the repair layer 54 is distributed around the innermost layer of the outer sheath 5, and the repair layer 54 extends outward along the side wall of the outer sheath 5.

[0023] As Figures 1 - 3 shown in the figure, the semi-conductive layer 1 further includes a collar 11 and dimples 13. The outer side of the collar 11 penetrates through the inner side wall of the insulating layer 2, and the part of the dimples 13 is clamped inside the insulating layer 2. The tight combination of the collar 11 and the insulating layer 2 not only enhances the connection stability between the two layers. The existence of the dimples 13 increases the contact area between the semi-conductive layer 1 and the insulating layer 2, thereby enhancing the friction and bonding force between the two. In practical applications, when the wire is subjected to tensile, bending or other external forces, the design of the collar 11 and the dimples 13 can effectively disperse and bear these external forces, reducing the possibility of relative displacement or separation between the two layers. In the case where the wire moves frequently or is in a vibrating environment, the collar 11 can limit the sliding of the semi-conductive layer 1 inside the insulating layer 2, while the dimples 13 can further enhance this limiting effect, ensuring the structural integrity and performance stability of the wire;

[0024] As Figures 1 - 3 shown in the figure, the inner convex particles 12 are arranged inside the collar 11, and the dimples 13 are arranged on the outer ring of the collar 11. Their protruding shapes form a tight fitting relationship with the surrounding structures. When they come into contact with the insulating layer 2, they form a connection method similar to mortise and tenon, increasing the contact area and friction between the collar 11 and the insulating layer 2;

[0025] As Figure 1 、 Figure 2 and Figure 4 shown in the figure, the enhancement layer 4 further includes a braided wire mesh 42. The side walls of the enhancement filaments 41 and the braided wire mesh 42 penetrate through the inner side of the insulating layer 2, providing strong tensile and compressive capabilities for the entire structure. When the wire is subjected to external tensile or compressive forces, the enhancement filaments 41 can effectively bear and disperse these stresses, preventing the wire from deforming or breaking. The braided wire mesh 42, with its unique mesh structure, further enhances the integrity and stability of the enhancement layer 4. The fine mesh of the braided wire mesh 42 can evenly share the external force, making its action on the entire wire more balanced;

[0026] As Figure 1 、 Figure 2 andFigure 4 As shown, the braided wire mesh 42 and the side walls of the reinforcing wires 41 are connected in an intermittent distribution. When the wire is suddenly impacted or violently vibrated, the reinforcing wires 41 quickly bear the main impact force, while the braided wire mesh 42 evenly distributes the remaining force to the entire structure through the deformation and adjustment of its meshes, thereby avoiding structural damage caused by excessive local stress. Embodiment 2:

[0027] As Figure 1 , Figure 2 and Figure 5 shown, the outer sheath 5 further includes a protective layer 51, an anti-aging layer 52, and a waterproof layer 53. The innermost layer of the repair layer 54 is distributed around the innermost layers of the protective layer 51 and the anti-aging layer 52 and extends to the outside thereof. The inner layer of the protective layer 51 is sleeved on the outside of the corrosion-resistant layer 3. The protective layer 51 is tightly sleeved on the outside of the corrosion-resistant layer 3, which not only effectively protects the corrosion-resistant layer 3 from direct mechanical damage but also ensures the integrity of the entire sheath under harsh usage conditions. The anti-aging layer 52 is located inside the protective layer 51, and its main function is to resist the aging effects of factors such as ultraviolet rays, oxygen, and temperature changes on the sheath. The waterproof layer 53 is responsible for preventing water penetration. When the outer sheath 5 is slightly damaged, the repair layer 54 can quickly respond and fill the damaged area through the flow of materials, chemical reactions, or physical changes to restore the integrity and protective performance of the sheath.

[0028] As Figure 1 , Figure 2 and Figure 5 shown, the inner side of the anti-aging layer 52 is sleeved on the outside of the protective layer 51, the inner side of the waterproof layer 53 is sleeved on the outside of the anti-aging layer 52, and the repair layer 54 extends from the inner side of the anti-aging layer 52 to the inner side of the waterproof layer 53. The anti-aging layer 52 is tightly attached to the outside of the protective layer 51, providing additional protection and effectively slowing down the aging phenomenon that the protective layer 51 may exhibit due to long-term exposure to the external environment.
