Description

Technical Field

[0001] This utility model relates to the field of copper core technology, specifically a highly conductive copper core. Background Technology

[0002] Cables are conductors covered with insulation, protective layers, and shielding layers used to transmit electrical or signal current and voltage. They can be classified into high-voltage cables and low-voltage cables according to voltage. Although low-voltage cable lines are more expensive and more difficult to lay and maintain compared to low-voltage overhead lines and low-voltage insulated overhead lines, they are widely used in low-voltage power distribution systems due to their reliable operation, lack of poles, lack of ground occupation, unobstructed appearance, and less susceptibility to external influences.

[0003] Existing copper core cables, used as conductors for high-voltage power transmission, have poor external insulation layers with poor pressure resistance and protection. This can lead to damage over time, and small animals like rodents can easily gnaw on them, causing the cables to become unusable and severely impacting their lifespan.

[0004] Therefore, a highly conductive copper core is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a highly conductive copper core.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a highly conductive copper core, comprising multiple copper core bodies, an insulating layer being sleeved on the outside of the multiple copper core bodies, a filling layer being disposed between the multiple insulating layers, a waterproof layer being wrapped around the filling layer, a flame-retardant layer being wrapped around the waterproof layer, a pressure-resistant layer being wrapped around the flame-retardant layer, and a protective layer being wrapped around the pressure-resistant layer.

[0007] Preferably, the protective layer includes an outer protective layer, an armored steel wire layer, and an inner protective layer. The armored steel wire layer wraps around the outside of the inner protective layer, and the outer protective layer wraps around the outside of the armored steel wire layer. The armored steel wire layer is located between the outer and inner protective layers, and is fixedly connected to the outer and inner protective layers on opposite sides. By using the outer protective layer, armored steel wire layer, and inner protective layer, the cable body is easily protected from external damage, the impact of external damage is reduced, and the protective performance is improved.

[0008] Preferably, the waterproof layer material is a TPU-specific protective material, which further improves the waterproof performance of the copper core itself.

[0009] Preferably, the compression-resistant layer comprises a first high-modulus high-strength polymer layer, a flexible steel strip, and a second high-modulus high-strength polymer layer. The flexible steel strip is disposed outside the first high-modulus high-strength polymer layer, and the second high-modulus high-strength polymer layer is disposed outside the flexible steel strip. The flexible steel strip is located between the first and second high-modulus high-strength polymer layers, and is fixedly connected to the first and second high-modulus high-strength polymer layers on opposite sides. By using the compression-resistant layer, the first high-modulus high-strength polymer layer, the flexible steel strip, and the second high-modulus high-strength polymer layer can increase the cable's impact resistance, enabling the cable to withstand greater impacts without damage.

[0010] Preferably, the flame-retardant layer is made of cross-linked polyethylene flame-retardant material. The flame-retardant layer can effectively delay or prevent the material from being ignited, prevent the fire from spreading rapidly, protect the cable body, and avoid causing significant losses.

[0011] Preferably, the plurality of copper core bodies are arranged in a uniform ring around one of the copper core bodies.

[0012] Preferably, the thickness of the waterproof layer is 0.2-0.3 mm, the thickness of the flame-retardant layer is 0.3-0.4 mm, the thickness of the compressive strength layer is 0.5-0.7 mm, and the thickness of the protective layer is 0.7-0.9 mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the pressure-resistant layer, including the first high-modulus high-strength polymer layer, the flexible steel strip, and the second high-modulus high-strength polymer layer, can increase the impact resistance of the cable itself, enabling the cable to withstand greater impacts without damage, thereby improving the service life of the cable itself.

[0015] 2. This utility model, through the setting of a protective layer, consisting of an outer protective layer, an armored steel wire layer, and an inner protective layer, facilitates the protection of the cable body when it is damaged by external forces, reduces the impact of external damage, improves protective performance, ensures the normal use of the cable body, and enhances the overall performance of the cable.

[0023] Please see Figures 1 to 4 A highly conductive copper core includes multiple copper core bodies 1. Each copper core body 1 is covered with an insulation layer 2, which provides insulation protection. A filler layer 3 is provided between the insulation layers 2 to ensure a tight fit between adjacent copper core bodies 1, improving stability during use.

The waterproof layer 4 is made of TPU special protective material, which further improves the waterproof performance of the copper core body 1.

[0024] Please see Figure 1 Figure 2 as well as Figure 4The flame-retardant layer 5 is wrapped with a pressure-resistant layer 6. The pressure-resistant layer 6 includes a first high-modulus high-strength polymer layer 61, a flexible steel strip 62, and a second high-modulus high-strength polymer layer 63. The flexible steel strip 62 is disposed outside the first high-modulus high-strength polymer layer 61, and the second high-modulus high-strength polymer layer 63 is disposed outside the flexible steel strip 62. The flexible steel strip 62 is located between the first high-modulus high-strength polymer layer 61 and the second high-modulus high-strength polymer layer 63, and is fixedly connected to the first high-modulus high-strength polymer layer 61 and the second high-modulus high-strength polymer layer 63 on the opposite side. Through the provision of the pressure-resistant layer 6, the first high-modulus high-strength polymer layer 61, the flexible steel strip 62, and the second high-modulus high-strength polymer layer 63 can increase the impact resistance of the cable itself, enabling the cable to withstand greater impacts without damage.

[0025] Please see Figure 1 and Figure 2 Multiple copper core bodies 1 are arranged in a uniform ring around one of the copper core bodies 1.

[0026] Please see Figures 1 to 3 The pressure-resistant layer 6 is wrapped with a protective layer 7.

The armored steel wire layer 72 is located between the outer protective layer 71 and the inner protective layer 73, and the armored steel wire layer 72 is fixedly connected to the outer protective layer 71 and the inner protective layer 73 on the opposite side. By setting up the protective layer 7, and utilizing the outer protective layer 71, the armored steel wire layer 72, and the inner protective layer 73, it is convenient to protect the cable body when it is damaged by external forces, reduce the impact of external damage, and improve the protective performance.
