Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a copper-clad aluminum conductor photovoltaic wire. Background Technology

[0002] Photovoltaic (PV) equipment is an environmentally friendly device that generates electricity using solar energy. It directly converts solar energy into electrical energy through photovoltaic modules and is widely used in residential, commercial, and industrial sectors. A typical PV system includes photovoltaic panels, inverters, batteries, mounting systems, and wiring. Its advantages include sustainable power generation, zero pollution emissions, and low maintenance costs. PV panels utilize high-efficiency crystalline silicon materials to maximize sunlight absorption and are designed to be UV-resistant, corrosion-resistant, and waterproof, ensuring stable operation in various harsh environments. With technological advancements, PV equipment has become an important component of clean energy development, providing strong support for achieving carbon neutrality goals. During operation, most PV systems use copper-clad aluminum photovoltaic cables to transmit electricity.

[0003] Existing photovoltaic wires generally have weak protective performance, which makes them susceptible to external environmental influences during long-term use, such as ultraviolet radiation, rainwater corrosion, and insufficient tensile strength and impact resistance. This shortens their service life, increases maintenance and replacement costs, and affects the overall efficiency and safety of the photovoltaic system, requiring further improvement. To this end, a copper-clad aluminum conductor photovoltaic wire is proposed. Utility Model Content

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

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A copper-clad aluminum conductor photovoltaic wire includes an aluminum conductor, a copper conductor fixedly sleeved on the outer cylindrical surface of the aluminum conductor, a tin outer shell fixedly sleeved on the outer cylindrical surface of the copper conductor, a waterproof layer on the outer surface of the tin outer shell to improve the waterproof performance of the photovoltaic wire, an impact-resistant layer on the outer surface of the waterproof layer to improve the strength of the photovoltaic wire, and a protective layer on the outer surface of the impact-resistant layer to improve the corrosion resistance and UV resistance of the photovoltaic wire.

[0007] Preferably, the waterproof layer includes a waterproof membrane, which is fixedly sleeved on the outer surface of the tin shell. The outer surface of the waterproof membrane is provided with fiberglass cloth, and the outer surface of the fiberglass cloth is coated with a graphene waterproof coating.

[0008] Preferably, the impact-resistant layer includes a second rubber sleeve, which is sleeved on the outer surface of the fiberglass cloth. A first rubber sleeve is disposed on the outer surface of the second rubber sleeve. An asphalt layer is disposed between the second rubber sleeve and the first rubber sleeve. A plurality of steel wires arranged in a ring array are sleeved inside the asphalt layer.

[0009] Preferably, the diameter of the steel wire is 0.5mm-0.8mm.

[0010] Preferably, the protective layer includes a primer coating disposed on the outer surface of the first rubber sleeve, the outer surface of the primer coating is provided with a polyurea coating, and the outer surface of the polyurea coating is provided with an acrylic coating.

[0011] Preferably, the thickness of the acrylic coating is 0.05 mm to 0.2 mm, and the thickness of the polyurea coating is 0.5 mm to 2 mm.

[0012] Preferably, the aluminum conductor (1), copper conductor (2) and tin shell (3) are all flat, and a number of triangular blocks (7) arranged in a linear array are installed on the upper end of the tin shell (3), and the triangular blocks (7) are located inside the waterproof layer (4).

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting a protective layer, the outer surface of the wire can be protected against corrosion and ultraviolet radiation. When in 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, and can be used for a long time under extreme temperature and sunlight. The polyurea coating has extremely high corrosion resistance and wear resistance, which can effectively protect the surface of the wire from external environmental damage such as chemical corrosion and mechanical damage, and extend the service life of the wire.

[0015] The impact-resistant layer can improve the strength of the wire. When in use, the asphalt layer can provide a sealing and protective function, 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, which can improve the outer layer's ability to withstand external forces, such as tensile strength and bending strength, and reduce damage caused by mechanical stress during transportation, installation and use.

[0016] By setting up a waterproof layer, the waterproof performance of the wires can be improved. The graphene waterproof coating has excellent hydrophobicity, which can effectively block water penetration and improve the durability of photovoltaic wires in humid environments. The waterproof membrane can provide an extra layer of protection for photovoltaic wires, further preventing water penetration and improving overall protection performance.

[0017] By setting the triangle block 7, the reflection efficiency of the acrylic coating 63 can be improved, preventing light from directly penetrating or scattering, and improving the utilization rate of light. Attached Figure Description

[0028] The waterproof layer 4 includes a waterproof membrane 43, which is fixedly sleeved on the outer surface of the tin shell 3. A fiberglass cloth 42 is provided on the outer surface of the waterproof membrane 43, and 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 graphene waterproof coating 41 and the fiberglass cloth 42 work together to effectively block water penetration and improve the durability of the photovoltaic wire in a humid environment. The waterproof membrane 43 can provide an extra layer of protection for the photovoltaic wire, further preventing water penetration and improving the overall protective performance. The waterproof membrane 43 is a PE membrane.

[0029] In addition, the impact-resistant layer 5 includes a second rubber sleeve 54, which is fitted onto 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. Several steel wires 53 arranged in a ring array are embedded inside the asphalt layer 52. The diameter of the steel wires 53 is 0.5mm-0.8mm.

The protective layer 6 is used to improve the corrosion resistance and UV resistance of the photovoltaic wire. When the light intensity is strong, the acrylic coating 63 has good UV resistance, which can resist UV radiation for a long time to ensure that the wire does not fade or age, and ensures long-term use under extreme temperatures and sunlight. 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 environmental damage such as chemical corrosion and mechanical damage, extending the service life of the wire.

[0031] Example 2, as Figure 5 As shown, the aluminum conductor 1, copper conductor 2, and tin shell 3 are all flat. Several triangular blocks 7 arranged in a linear array are installed on the upper end of the tin shell 3. The triangular blocks 7 are located inside the waterproof layer 4. The upper ends of the waterproof layer 4, the impact-resistant layer 5, and the protective layer 6 are formed by the support of the triangular blocks 7, and the angle between two triangular blocks 7 is 138°. The wires are installed inside the photovoltaic panel.
