Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic technology, and particularly relates to a copper-clad aluminum conductor photovoltaic wire. Background Art

[0002] Photovoltaic equipment is an environmental protection device that uses solar energy to generate electricity. It directly converts solar energy into electrical energy through photovoltaic modules and is widely used in household, commercial, and industrial fields. A photovoltaic system usually includes components such as photovoltaic panels, inverters, storage batteries, brackets, and wiring. Its advantages lie in sustainable power generation, zero pollution emissions, and low maintenance costs. Photovoltaic panels use high-efficiency crystalline silicon materials to maximize the absorption of sunlight and are combined with ultraviolet resistance, corrosion prevention, and waterproof design to ensure stable operation in various harsh environments. With technological progress, photovoltaic equipment has become an important part of the development of clean energy and provides strong support for promoting the carbon neutrality goal. When photovoltaic equipment is in use, most use copper-clad aluminum photovoltaic wires to transmit electricity.

[0003] Most of the existing photovoltaic wires have weak protection performance, which can cause the wires to be easily affected by the external environment during long-term use, such as ultraviolet radiation, rainwater corrosion, and lack of sufficient tensile strength and impact resistance, thereby shortening the service life and ultimately increasing the costs of maintenance and replacement, affecting the overall efficiency and safety of the photovoltaic system, and further improvement is needed. For this reason, a copper-clad aluminum conductor photovoltaic wire is proposed. Summary of the Invention

[0004] The main purpose of the present invention is to provide a copper-clad aluminum conductor photovoltaic wire, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A copper-clad aluminum conductor photovoltaic wire includes an aluminum conductor. A copper conductor is fixedly sleeved on the outer cylindrical surface of the aluminum conductor. A tin outer shell is fixedly sleeved on the outer cylindrical surface of the copper conductor. A waterproof layer is provided on the outer surface of the tin outer shell. The waterproof layer is used to improve the waterproof performance of the photovoltaic wire. An impact-resistant layer is provided on the outer surface of the waterproof layer. The impact-resistant layer is used to improve the strength of the photovoltaic wire. A protective layer is provided on the outer surface of the impact-resistant layer. The protective layer is used to improve the corrosion resistance and ultraviolet resistance of the photovoltaic wire.

[0006] Preferably, the waterproof layer includes a waterproof film. The waterproof film is fixedly sleeved on the outer surface of the tin outer shell. A fiberglass cloth is provided on the outer surface of the waterproof film. A graphene waterproof coating is coated on the outer surface of the fiberglass cloth.

[0007] Preferably, the impact-resistant layer includes a second rubber sleeve sleeved on the outer surface of the fiberglass cloth. A first rubber sleeve is provided on the outer surface of the second rubber sleeve. An asphalt layer is provided between the second rubber sleeve and the first rubber sleeve. A plurality of steel wires are sleeved inside the asphalt layer and are distributed in an annular array.

[0008] Preferably, the diameter of the steel wire is 0.5 mm - 0.8 mm.

[0009] Preferably, the protective layer includes a primer coating provided on the outer surface of the first rubber sleeve. A polyurea coating is provided on the outer surface of the primer coating. An acrylic coating is provided on the outer surface of the polyurea coating.

[0010] Preferably, the thickness of the acrylic coating is 0.05 mm - 0.2 mm, and the thickness of the polyurea coating is 0.5 mm - 2 mm.

[0011] Preferably, the aluminum conductor (1), the copper conductor (2) and the tin shell (3) are all in a flat shape. A plurality of triangular blocks (7) distributed in a linear array are installed at the upper end of the tin shell (3). The triangular blocks (7) are located inside the waterproof layer (4).

[0012] Compared with the prior art, the present invention has the following beneficial effects: By providing the protective layer, the anti-corrosion and anti-ultraviolet performance of the outer surface of the wire can be improved. During use, the acrylic coating has good ultraviolet resistance and can resist ultraviolet radiation for a long time to ensure that the wire does not fade or age, ensuring that it can be used for a long time under extreme temperatures and sunlight. The polyurea coating has extremely high corrosion resistance and wear resistance, and can effectively protect the wire surface from being damaged by the external environment such as chemical corrosion and mechanical damage, extending the service life of the wire; By the impact-resistant layer, the strength of the wire can be improved. During use, the asphalt layer can provide a sealing and protective effect, which can isolate corrosive substances such as moisture and oxygen. After embedding steel wires in the asphalt layer, it can provide additional support for the asphalt layer structure, improving the bearing capacity of the outer layer against external forces such as tensile strength and bending resistance, and reducing damage caused by mechanical stress during transportation, installation and use; By providing the waterproof layer, the waterproof performance of the wire can be improved. The graphene waterproof coating has excellent hydrophobicity and can effectively block moisture penetration, enhancing the durability of the photovoltaic wire in a humid environment. The waterproof membrane can provide an additional layer of protection for the photovoltaic wire, further preventing moisture from seeping in and improving the overall protection performance; By providing the triangular blocks 7, the reflection efficiency of the acrylic coating 63 can be improved, avoiding direct penetration or scattering of light and improving the utilization rate of light.

A fiberglass cloth 42 is provided on the outer surface of the waterproof film 43. A graphene waterproof coating 41 is coated on the outer surface of the fiberglass cloth 42. The waterproof layer 4 is used to improve the waterproof performance of the photovoltaic wire. The graphene waterproof coating 41 has excellent hydrophobicity. The cooperation of the graphene waterproof coating 41 and the fiberglass cloth 42 can effectively block the penetration of moisture and improve the durability of the photovoltaic wire in a humid environment. The waterproof film 43 can provide an additional layer of protection for the photovoltaic wire, further preventing moisture from seeping in and improving the overall protection performance. The waterproof film 43 is a PE film.

[0020] In addition, the impact-resistant layer 5 includes a second rubber sleeve 54. The second rubber sleeve 54 is sleeved on the outer surface of the fiberglass cloth 42. A first rubber sleeve 51 is provided on the outer surface of the second rubber sleeve 54. An asphalt layer 52 is provided between the second rubber sleeve 54 and the first rubber sleeve 51. A number of steel wires 53 distributed in an annular array are sleeved inside the asphalt layer 52. The diameter of the steel wires 53 is 0.5 mm - 0.8 mm. The impact-resistant layer 5 is used to improve the strength of the photovoltaic wire.

When corrosive substances adhere to the surface of the wire, the polyurea coating 62 has extremely high corrosion resistance and wear resistance, which can effectively protect the wire surface from external environments such as chemical corrosion and mechanical damage, and extend the service life of the wire.
