[0002] With the scarcity of copper resources and rising copper prices, more and more customers are favoring aluminum or aluminum alloy core cables. However, for cables that require mobile installation, replacing copper with aluminum requires Category 5 aluminum alloy conductors to ensure the product's bending and tensile properties, such as aluminum alloy core flexible cables for photovoltaic power generation systems and aluminum alloy core wind power cables. Currently, Category 2 aluminum alloy conductor technology is relatively mature both domestically and internationally, while the processing of Category 5 aluminum alloy conductors still faces technical bottlenecks, primarily due to the need to overcome surface oil contamination and scratch resistance.

[0008] S4. Extrusion of insulation and sheath at one time: The annealed and cooled cable core is passed through an extruder to extrude an insulation layer on the outside of the cable core. After the extrusion is completed, it enters the extruder head to produce a sheath layer on the outside of the insulation layer. In order to avoid adhesion between the insulation layer and the sheath layer, a layer of talcum powder is coated on the outside of the insulation layer by electrostatic adsorption as an isolation agent to ensure that the insulation layer and the sheath layer do not adhere to each other, making it easier to strip the wire during construction.

[0009] S5, irradiation cross-linking: a single irradiation is used after the insulation layer and the sheath layer are extruded;

[0010] S6. Finished product monitoring and packaging: After irradiation, the products are inspected and then packaged.

[0011] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, in the S1 wire drawing step, a water-soluble emulsion is added during the wire drawing process to avoid the quality defect of darkening the conductor surface after annealing.

[0012] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, the water-soluble emulsion is composed of 15% mineral oil, 20% emulsifier, 25% surfactant, 10% rust inhibitor, 5% polar additive, 5% friction modifier, 10% antioxidant and 10% soft water, and needs to be dissolved in water at a ratio of 1:3 before use.

[0013] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, in the S2 conductor bundle twisting step, the drawn conductors are twisted into a cable core using a sliding friction wire passing method.

[0014] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, in the S2 conductor bundle twisting step, the conductors after wire drawing are twisted into a cable core. If the area of ​​the conductors after twisting is greater than 6 square millimeters, the conductors are re-twisted and then annealed after re-twisting. If the area of ​​the conductors after twisting is less than or equal to 6 square millimeters, annealing is directly performed.

[0015] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, in the S4 insulation and sheath one-time extrusion step, the annealed and cooled cable core is passed through an extruder with an inner diameter of 70 mm to extrude an insulation layer outside the cable core. After the extrusion is completed, it is immediately cooled and shaped, blown dry, and talcum powdered, and then enters the extruder head with an inner diameter of 90 mm to produce the sheath layer outside the insulation layer.

[0016] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, in the S5 irradiation cross-linking step, a single irradiation form is used after the insulation layer and the sheath layer are extruded, and the cable core covered with the insulation layer and the sheath layer is irradiated with an electron beam in an 8-shaped winding method.

[0017] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, a horizontally arranged fixing rod is fixedly installed on the outside of the wire drawing machine, an auxiliary plate is fixedly installed on the fixing rod by bolts, two assembly blocks are provided on the auxiliary plate, the assembly blocks are provided with an assembly groove, a rotatable first cylinder is provided in the assembly groove, and several rotatable second cylinders are also provided on the auxiliary plate, the first cylinder is arranged horizontally, and the second cylinder is arranged vertically.

[0018] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, in the S2 conductor bundle twisting step, the twisted conductor is passed between the two second cylinders to detect whether the diameter of the twisted conductor is qualified. After passing through, the conductor is rolled up by a roller mechanism provided outside the wire drawing machine.

[0019] According to the aluminum alloy conductor processing process described in the embodiment of the first aspect of the present invention, the roller mechanism includes a roller, a rotating shaft and a cylinder, and fixed plates are provided at both ends of the roller. The fixed plate close to the wire drawing machine is connected to the telescopic end of the cylinder to adjust the winding angle.

[0020] One of the above technical solutions of the present invention has at least one of the following advantages or beneficial effects:

[0021] The present invention adopts a coated nano-mold when twisting the conductors. This mold is resistant to high temperatures and has a smooth inner wall. The surface of the conductor after twisting is bright, round and undamaged. At the same time, the scratching phenomenon on the conductor surface is reduced and no aluminum chips are generated. The present invention adopts a process of twisting first and then annealing. Because a layer of oil film on the surface of the conductor will be evaporated after annealing, if the conductor is twisted directly after annealing, the scratch resistance of the conductor surface will be worse, so as to reduce the easy scratching phenomenon of the conductor surface. By improving the processing technology of aluminum alloy conductors, the surface quality of the conductor can be effectively controlled, ensuring that the surface of the conductor after twisting is bright and round, and there is no quality risk of darkening the surface after annealing.

[0031] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0032] Reference Figures 1 to 3 As shown, a process for processing an aluminum alloy conductor is provided, comprising the following steps:

[0033] S1. Wire drawing: Select the 8030 series aluminum alloy rod required for processing and draw it through a wire drawing machine multiple times to make a conductor of the required diameter;

[0034] S2. Conductor bundle stranding: The wire-drawn conductors are stranded into cable cores. During stranding, the conductors pass through a nano-coated die that is heat-resistant and has a smooth inner wall. The stranded conductors have a bright and rounded appearance.

[0035] S3, Annealing: Annealing the cable core to reduce its hardness and improve its flexibility;

[0036] S4. Extrusion of insulation and sheath at one time: The annealed and cooled cable core is passed through an extruder to extrude an insulation layer on the outside of the cable core. After the extrusion is completed, it enters the extruder head to produce a sheath layer on the outside of the insulation layer. In order to avoid adhesion between the insulation layer and the sheath layer, a layer of talcum powder is coated on the outside of the insulation layer through electrostatic adsorption as an isolation agent to ensure that the insulation layer and the sheath layer do not adhere to each other, making it easier to strip the wire during construction.

[0037] S5, irradiation cross-linking: a single irradiation is used after the insulation layer and the sheath layer are extruded;

[0038] S6. Finished product monitoring and packaging: After irradiation, the products are inspected and then packaged.

[0039] This aluminum alloy conductor processing technology uses 8 series aluminum alloy rods for wire drawing. Among the 8 series aluminum alloy rods, 8030 series aluminum alloy rods with better strength and bending properties are selected. Wire drawing is divided into large drawing step and fine drawing step. The large drawing step is to simply draw the 8030 series aluminum alloy rod. The fine drawing step is to draw the 8030 series aluminum alloy rod after large drawing again to obtain the desired conductor. Before using the 8030 series aluminum alloy rod, the material needs to be tested. The unqualified ones will be dealt with in time, and the qualified ones will flow to the next step normally. The conductor after fine drawing also needs to be tested and then flow to the conductor bundle twisting step. The bundled conductor is annealed to reduce its hardness and improve The cable core with high flexibility and annealing to be cooled is passed through an extruder to extrude an insulation layer on the outside of the cable core. After the extrusion is completed, it enters the extruder head to produce the sheath layer on the outside of the insulation layer. In order to avoid adhesion between the insulation layer and the sheath layer, a layer of talcum powder is coated on the outside of the insulation layer by electrostatic adsorption as an isolation agent to ensure that there is no adhesion between the insulation layer and the sheath layer, which is convenient for construction and stripping. After the insulation and sheath are extruded once, it is necessary to detect whether the insulation layer and the sheath layer are adhered. The unqualified ones will be removed and the qualified ones will continue to circulate. In order to improve production efficiency, the insulation layer and the sheath layer are irradiated once after extrusion. The irradiated products are tested and the qualified ones are packaged.

[0040] The present invention adopts a process of twisting first and then annealing. Because a layer of oil film on the surface of the conductor will be evaporated after annealing, if the conductor is twisted directly after annealing, the scratch resistance of the conductor surface will be worse, so as to reduce the easy scratching phenomenon of the conductor surface. By improving the processing technology of aluminum alloy conductors, the surface quality of the conductor can be effectively controlled, ensuring that the surface of the conductor after twisting is bright and round, and there is no quality risk of dark surface after annealing. When twisting the conductor, a coated nano-mold is used. This mold is resistant to high temperature and has a smooth inner wall. The surface of the conductor after twisting is bright, round and undamaged, and at the same time, the scratching phenomenon on the conductor surface is reduced and no aluminum chips are generated.

[0041] Due to the limited space required for laying photovoltaic cables, especially the connection wiring between photovoltaic modules, and the inevitable dragging and bending during installation, the cables must have a certain degree of tensile strength and flexibility. Therefore, the strength and bending properties of aluminum alloy conductors must be considered when selecting them. According to the German standard 2PFG2642:2022, 8 series aluminum alloy rods must be used for the conductors. After preliminary welding and experimental verification, 8030 series aluminum alloy rods with excellent strength and bending properties were selected. The main performance parameters compared with other aluminum alloy rods are as follows:

[0042] 8A07 aluminum alloy rod (H15 state), maximum resistivity is 28.64Ω.mm 2 / m, tensile strength of 95-135MPa, elongation at break of 7%; 8030 aluminum alloy rod (H14 state), maximum resistivity of 29.73Ω.mm 2 / m, tensile strength of 105-155MPa, elongation at break of 10%; 8E76 aluminum alloy rod (H12 state), maximum resistivity of 28.45Ω.mm 2 / m, tensile strength is 85-125MPa, and elongation at break is 11%.

[0043] In some embodiments, in the S1 wire drawing step, a water-soluble emulsion is added during the wire drawing process to avoid the quality defect of darkening of the conductor surface after annealing. The water-soluble emulsion is composed of 15% mineral oil, 20% emulsifier, 25% surfactant, 10% rust inhibitor, 5% polar additive, 5% friction modifier, 10% antioxidant and 10% soft water. It needs to be dissolved in water at a ratio of 1:3 before use.

[0044] When drawing conductors, a water-soluble emulsion is used. This emulsion has good fluidity and can effectively flush aluminum powder, preventing aluminum chips from adhering to and clogging the drawing die of the wire drawing machine. It reduces oil stains on the conductor surface, avoiding the quality defect of darkening the conductor surface after annealing, while improving the reliability of welding between the conductor and the copper wire terminal. It also improves the working environment in the workshop, without generating oil smoke or posing a potential safety hazard of fire.

[0045] The emulsion's excellent fluidity facilitates the separation and handling of aluminum powder, resulting in minimal oil stains on the surface of the drawn aluminum alloy monofilaments. This ensures a clean and environmentally friendly production site, while also avoiding the risk of conductor discoloration after annealing caused by the oily drawing emulsion. A filter layer is installed at the return outlet of the drawing lubricant tank to remove aluminum shavings generated by the friction between the drawing die and the guide pulley during the drawing process. This effectively prevents excessive aluminum shavings from floating at the die mouth and causing wire breakage, maintaining stable and long-term drawing operations and improving work efficiency.

[0046] In some embodiments, in the conductor bundle twisting step S2, the drawn conductors are twisted into a cable core by using a sliding friction method.

[0047] In order to overcome the technical difficulty of aluminum alloy conductors being easily broken by scraping during stranding, the conductors are passed through the strands using sliding friction, which greatly reduces the friction between the conductors and the equipment and reduces the scratching of the conductor surface. The assembled mold for stranding uses a nano-coated mold, which is resistant to high temperatures and has a smooth inner layer. The surface of the conductor after stranding is smooth and undamaged, and no aluminum chips are generated.

[0048] The guide pulleys used for conductor bundle stranding all utilize a sliding design. Because fine aluminum alloy monofilaments are susceptible to scratching and wire breakage during stranding, the guide pulleys utilize a sliding ceramic mold. The assembly mold also utilizes a nano-coated mold. This mold is heat-resistant and features smooth walls. The stranded conductors are shiny and free of aluminum chips, effectively preventing mechanical damage to the aluminum alloy wire surface and wire breakage.

[0049] In some embodiments, in the S2 conductor bundle twisting step, the conductors after drawing are twisted into a cable core. If the area of ​​the conductors after twisting is greater than 6 square millimeters, the conductors are re-twisted and then annealed. If the area of ​​the conductors after twisting is less than or equal to 6 square millimeters, annealing is directly performed. After the conductors are re-twisted, they need to be tested for quality. If they are qualified, they are circulated normally. If they are unqualified, they are disposed of.

[0050] In some embodiments, in the S4 insulation and sheath one-time extrusion step, the annealed and cooled cable core is passed through an extruder with an inner diameter of 70 mm to extrude an insulation layer outside the cable core. After the extrusion is completed, it is immediately cooled and shaped, blown dry, and talcum powdered, and then enters the extruder head with an inner diameter of 90 mm to produce the sheath layer outside the insulation layer.

[0051] Before the S4 insulation and sheath primary extrusion step, it is necessary to test whether the annealed conductor meets the requirements before proceeding to the next step.

[0052] To improve production efficiency, the company successfully transformed the production line into a Φ70 and Φ90 series production line by adding traction devices, cooling devices, and changing the threading position of the die head. This enabled the insulation and sheath layers of the cable to be extruded in one go. The insulation was produced on the Φ70 extruder, immediately cooled and shaped, blown dry, and talcum powdered after extrusion, before entering the Φ90 extruder die head to produce the sheath. To prevent adhesion between the insulation and sheath, a layer of talcum powder was applied to the outside of the insulation through electrostatic adsorption as a release agent. This ensured that the insulation and sheath layers did not adhere to each other and were easily peeled off, facilitating wire stripping. The conductor pay-off was a double-reel, swing-bucket pay-off method, enabling continuous reel change. This not only improved production efficiency but also avoided mechanical damage to the cable during multiple reels. This also reduced energy consumption, achieving a green and low-carbon approach.

[0053] In some embodiments, in the S5 irradiation cross-linking step, a single irradiation form is used after the insulation layer and the sheath layer are extruded, and the cable core covered with the insulation layer and the sheath layer is irradiated with an electron beam in an 8-shaped winding manner, that is, the cable is wound into an 8-shape and then irradiated with an electron beam. This ensures that the cable is evenly irradiated with an electron beam around it. Before the S5 irradiation cross-linking step, it is necessary to detect whether the cable extruded with the insulation and sheath at one time is qualified, and then perform irradiation cross-linking.

[0054] In one embodiment of the present invention, a horizontally arranged fixing rod 1 is fixedly installed on the outside of the wire drawing machine, an auxiliary plate 2 is fixedly installed on the fixing rod 1 by bolts, two assembly blocks 3 are provided on the auxiliary plate 2, the assembly blocks 3 are provided with an assembly groove 31, a rotatable first cylinder 4 is provided in the assembly groove 31, and several rotatable second cylinders 5 are also provided on the auxiliary plate 2, the first cylinder 4 is arranged horizontally, and the second cylinder 5 is arranged vertically.

[0055] Preferably, in the conductor bundle twisting step S2, the twisted conductor is passed between the two second cylinders 5 to check whether the diameter of the twisted conductor is qualified. After passing through, the conductor is wound up by a roller mechanism provided outside the wire drawing machine.

[0056] There are ten second cylinders 5, which are evenly distributed on the auxiliary plate 2, and the ten second cylinders 5 are all arranged on the same side of the first cylinder 4. The twisted conductor needs to contact the first cylinder 4 before passing through the two second cylinders 5. The first cylinder 4 is the wire guide wheel, and several second cylinders 5 are a collective mold. The first cylinder 4 and the second cylinder 5 are both sliding wire guides, which effectively avoids mechanical damage to the surface of the aluminum alloy wire and wire breakage.

[0057] In one embodiment of the present invention, the roller mechanism includes a roller 11, a rotating shaft 12 and a cylinder 13. Fixed plates 14 are provided at both ends of the roller 11. The fixed plate 14 close to the wire drawing machine is connected to the telescopic end of the cylinder 13 to adjust the winding angle. By adjusting the telescopic end of the cylinder 13, the fixed plate 14 connected to the telescopic end can follow the rotation. Since one end of the fixed plate 14 is connected to the rotating shaft 12 for rotation, when the telescopic end of the cylinder 13 is extended or retracted, the fixed plate 14 will rotate, so that the roller 11 set on the fixed plate 14 will move away from or close to one side of the second cylinder 5, which is convenient for better winding.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
