Description

Technical Field

[0001] The invention relates to the technical field of wind energy torsion resistant cables, in particular to a novel aluminum alloy combined conductor wind energy torsion resistant flexible cable. Background Art

[0002] Electromagnetic wires are usually wound into coils in electrical products such as motors and transformers, using the principle of electromagnetic induction to achieve the mutual conversion of electrical energy and magnetic energy. As the use environment changes, the temperature resistance level of ordinary electromagnetic wires is difficult to meet the needs of aerospace and other fields. The high-temperature resistant electromagnetic wires currently developed in China usually use an insulating layer composed of organic and inorganic materials such as organic insulating varnish and glass fiber. However, since the single filaments of glass fiber are finer and the number of strands is larger, the filaments are loose and disorderly arranged after winding. Since the filaments are not bonded, the thickness of the insulating layer formed after winding is uneven, and the single-sided insulation thickness of this structure is usually more than 0.15mm. Compared with the paint film thickness of ordinary electromagnetic wires of about 0.1mm, this type of high-temperature resistant electromagnetic wire appears to be quite thick and the insulation thickness is uneven.

[0003] In addition, the conductor structure of the traditional wind energy torsion-resistant flexible cable adopts GB / T3956 standard Class 5 copper conductor, which is costly, heavy, and has poor torsion resistance and tensile strength. During torsion tests and actual torsion applications, conductor strands often break. Moreover, the insulation layer and sheath layer of the traditional wind energy torsion-resistant flexible cable often have poor tear resistance and cracking during torsion tests and actual torsion applications, which ultimately limits the development and application areas of traditional wind energy torsion-resistant flexible cables.

[0039] The invention provides a novel aluminum alloy combined conductor wind energy twisting resistant flexible cable, which has the characteristics of light weight, super flexibility, high twisting resistance and high cold resistance.

[0040] like Figure 1As shown, the new aluminum alloy combined conductor wind energy resistant twisting flexible cable comprises a conductor unit 10, an isolation layer 20, an insulating layer 30 and a sheath layer 40 arranged in sequence from the inside to the outside. The conductor unit 10 is an electrical unit of the new aluminum alloy combined conductor wind energy resistant twisting flexible cable. The conductor unit 10 comprises a first conductor layer 101 and a second conductor layer 102. The first conductor layer 101 is formed by twisting multiple layers of first conductor units 51. The second conductor layer 102 is formed by at least one layer of second conductor units 61 twisted around the first conductor layer 101. Therefore, the first conductor layer 101 is the internal structure of the conductor unit 10, and the second conductor layer 102 is the external structure of the conductor unit 10.

[0041] In particular, in the first conductor layer 101, the first conductor unit 51 is a conductor strand formed by bundling a plurality of first aluminum alloy single wires 52, the first aluminum alloy single wires 52 are 8 series aluminum alloy, and the 8 series aluminum alloy is a Class 5 conductor, that is, the first aluminum alloy single wires 52 are 8 series Class 5 aluminum alloy, and the diameter of the first aluminum alloy single wires 52 is 0.49-0.495 mm; the 8 series Class 5 aluminum alloy makes the first conductor unit 51 inside the conductor unit 10 lightweight and has excellent electrical properties and flexibility, so that the first conductor unit 51 is not easily twisted off. In the second conductor layer 102, the second conductor unit 61 is a conductor strand formed by a plurality of second aluminum alloy single wires 62 bundled together. The second aluminum alloy single wire 62 is a 6 series aluminum alloy, which is a Class 5 conductor, i.e., the second aluminum alloy single wire 62 is a 6 series Class 5 aluminum alloy, and the diameter of the second aluminum alloy single wire 62 is 0.49-0.495 mm. The 6 series Class 5 aluminum alloy makes the second conductor unit 61 outside the conductor unit 10 lightweight and has high torsion resistance and high strength, so that the second conductor unit 61 is not easily twisted off, and improves the mechanical properties of the second conductor unit 61, thereby reducing the probability of broken wires of the second conductor unit 61 in the external second conductor layer 102 and saving costs. In addition, the first aluminum alloy monofilament 52 and the second aluminum alloy monofilament 62 are both ultra-fine Class 5 aluminum alloy soft monofilaments with a smooth surface and good mobility. In this way, when the new aluminum alloy combined conductor wind energy-resistant torsional soft cable is bent, the friction resistance and mutual restraint between the aluminum wires are reduced, which is conducive to the spiral sliding and stretching of the aluminum wires in the same direction, reducing the probability of wire breakage and improving the torsional resistance.

[0042] Furthermore, when manufacturing the new aluminum alloy combined conductor wind energy torsion resistant flexible cable, the bundling direction when multiple first aluminum alloy monofilaments 52 are bundled into the first conductor unit 51, the twisting direction when multiple strands of first conductor units 51 are twisted into the first conductor layer 101, the bundling direction when multiple second aluminum alloy monofilaments 62 are bundled into the second conductor unit 61, and the twisting direction when multiple strands of second conductor units 61 are twisted into the second conductor layer 102 are in the same direction, for example, all in the left direction or all in the right direction. This helps to reduce the bending modulus of the conductor twisting process and enhance the torsion resistance of the entire cable.

[0043] Furthermore, the isolation layer 20 is formed by wrapping aramid paper, the base material of which is aramid fiber, and the wrapping overlap rate is controlled at 25-30%; aramid paper has many excellent properties such as excellent high temperature resistance, oxidation resistance and low temperature resistance, and plays a role in wrapping and isolating the conductor unit 10, while maintaining the flexibility of the conductor in the conductor unit 10, improving the roundness of the conductor, and improving the high temperature resistance, oxidation resistance and low temperature resistance, and enhancing the stability of the overall conductor during the twisting resistance process. The insulation layer 30 is formed by extrusion of high elastic rubber, and the base material of the high elastic rubber is ethylene propylene rubber (EPR). The insulation layer 30 can be used for a long time in an environment with a high temperature of 125°C and a low temperature of -55°C, which greatly improves the heat resistance and low temperature resistance of the insulation layer 30; at the same time, the volume resistivity of the insulation layer 30 can reach 1×10 17 Ω·m; Compared with the traditional EPDM, the present application greatly improves the heat resistance, low temperature resistance and mechanical properties of the insulation layer 30, and maintains excellent electrical properties. The sheath layer 40 is extruded from low temperature resistant rubber, and the base material of the low temperature resistant rubber is chlorosulfonated rubber with excellent water tightness. The sheath layer 40 can be used for a long time in an environment with a high temperature of 100°C and a low temperature of -55°C, which greatly improves the temperature resistance level of the sheath layer 40; at the same time, compared with the traditional chlorosulfonated polyethylene and chlorinated polyethylene rubber, the present application also greatly improves the tear resistance and low temperature resistance of the sheath layer 40, thereby improving the applicability of the wind energy torsion resistant flexible cable in a low temperature torsion environment.

[0044] In addition, the "substrate" mentioned above refers to the basic material, or the main raw material. Based on this, the main raw material of the aramid paper constituting the isolation layer 20 is aramid fiber, the main raw material of the high elastic rubber constituting the insulation layer 30 is EPDM rubber, and the main raw material of the low temperature resistant rubber constituting the sheath layer 40 is chlorosulfonated rubber.

[0045] In summary, the new aluminum alloy combined conductor wind energy resistant torsion soft cable involved in the present application has a stable structure, light weight, high tensile strength, excellent torsion bending resistance, excellent low temperature torsion resistance, excellent softness and other advantages. The combined conductor electrical unit structure composed of the ultra-fine first aluminum alloy monofilament 52 of 8 series 5 and the ultra-fine second aluminum alloy monofilament 62 of 6 series 5 makes the cable have good electrical properties and excellent mechanical properties, and is arranged as a non-tightly twisted cable, which reduces the damage of the conductor monofilament and improves the torsion resistance of the conductor; combined with the aramid paper wrapped isolation layer 20, the EPDM rubber insulation layer 30, and the chlorosulfonated rubber sheath layer 40, it not only ensures the electrical properties of the overall conductor, but also enhances the torsion resistance under normal temperature and low temperature environment, avoiding the poor tearing resistance and cracking that often occur during the torsion test and the actual application torsion process; compared with ordinary conductors, the applicability is greatly enhanced, and compared with the traditional copper core structure conductor cable, the cost of the cable is greatly reduced.

[0046] Furthermore, the diameters of the first aluminum alloy monofilament 52 and the second aluminum alloy monofilament 62 are both of the upper tolerance, that is, the diameters of the first aluminum alloy monofilament 52 and the second aluminum alloy monofilament 62 are both To ensure the electrical conductivity of the cable.

[0047] Further, in a preferred embodiment of the novel aluminum alloy combined conductor wind energy resistant torsion flexible cable, the twisted structure of the first conductor layer 101 is: Figure 1 As shown, the first conductor layer 101 is formed by twisting 37 first conductor units 51, and the 37 first conductor units 51 are arranged in an inner layer of 1 strand, a second layer of 6 strands, a second outer layer of 12 strands, and an outermost layer of 18 strands. The bundled structure of each first conductor unit 51 is as follows: Figure 2 As shown, each first conductor unit 51 is formed by bundling 34 first aluminum alloy monofilaments 52, and the 34 first aluminum alloy monofilaments 52 are arranged in three layers, namely, 6 in the inner layer, 11 in the middle layer, and 17 in the outer layer. The twisted structure of the second conductor layer 102 is as follows: Figure 1 As shown, the second conductor layer 102 is formed by twisting 24 second conductor units 61, and the 24 second conductor units 61 are arranged in a single layer. Figure 3 As shown, each second conductor unit 61 is formed by bundling 34 second aluminum alloy monofilaments 62, and the 34 second aluminum alloy monofilaments 62 are arranged in three layers, with 6 in the inner layer, 11 in the middle layer, and 17 in the outer layer. Therefore, the size specification of the first conductor layer 101 is 37×34 / 0.49 series 5 type aluminum alloy soft monofilaments, and the size specification of the second conductor layer 102 is 24×34 / 0.49 series 5 type aluminum alloy soft monofilaments.

[0048] The manufacturing process of the preferred embodiment of the above-mentioned new aluminum alloy combined conductor wind energy resistant torsion flexible cable includes the following steps.

[0049] First, 34 first aluminum alloy monofilaments 52 of 8 series 5 categories and all of which are 0.49 mm in diameter are bundled at one time in an arrangement of 6+11+17 from the inside to the outside, and the bundling direction is leftward, to form a first conductor unit 51; 37 first conductor units 51 are regularly twisted into a cable in an arrangement of 1+6+12+18 from the inside to the outside, to form a 37×34 / 0.49 8 series first conductor layer 101, which is a double-twisted aluminum alloy strand structure, and the twisting direction is leftward.

[0050] Second, 34 second aluminum alloy monofilaments 62 of 6 series and 5 categories, all of which are 0.49 mm, are bundled at one time in an arrangement of 6+11+17 from the inside to the outside, and the bundling is not tightly pressed, and the bundling direction is left, to form a second conductor unit 61; 24 second conductor units 61 are regularly twisted in the outer layer of the first conductor layer 101 in a single-layer arrangement to form a 24×34 / 0.49 6 series second conductor layer 102, and the second conductor layer 102 is a double-twisted aluminum alloy strand structure, and the twisting direction is left.

[0051] Third, the structure of 1 strand + 6 strands + 12 strands + 18 strands + 24 strands from the inside out is cabled for the last time, and the cabling direction is left-handed, to obtain the conductor unit 10. When cabling the conductor, a cabling machine with back-twisting and tension control functions is used. The specifications of the cabling machine determine the number of cabling times, which can be one-time cable twisting or three-time cable twisting. When cabling, ensure that the tension of each cabling unit is uniform. If it is cabled in three times, the three cabling directions are unified to the left, which is consistent with the twisting direction of the conductor.

[0052] Fourth, after cabling, a layer of super-soft aramid paper tape is wrapped around the outer periphery of the conductor unit 10 to form an isolation layer 20 fixed outside the conductor unit 10. After the conductor is cabled, in order to prevent the conductor unit 10 from being contaminated and to improve the roundness of the conductor unit 10, an aramid paper tape is wrapped around the outside. The primary bundled node diameter ratio is 20 times, the re-twisted node diameter ratio is 17 times that of the second layer of 6 strands, the re-twisted node diameter ratio is 15 times that of the second outer layer of 12 strands, and the re-twisted node diameter ratio is 12 times that of the outermost layer of 18 strands. This type of structural conductor has a stable structure, which not only ensures the electrical properties of the overall conductor, that is, the conductor resistance requirements, but also enhances the torsion resistance under normal and low temperature environments; compared with ordinary conductors, the applicability is greatly enhanced, and compared with traditional copper core structure conductor cables, the cost of the cable is greatly reduced.

[0053] Fifth, continuous vulcanization equipment and an extrusion die are used to extrude the insulating layer 30 and the sheath layer 40 by a one-time double-layer co-extrusion method of continuous vulcanization, so as to obtain the insulating layer 30 tightly wrapped outside the isolation layer 20, and the sheath layer 40 tightly wrapped outside the insulating layer 30. First, the insulating layer 30 and the sheath layer 40 are formed by extrusion, so that the insulating layer 30 can be tightly wrapped on the conductor, which greatly improves the stability of the cable and avoids insulation deformation of the cable during the manufacturing process and subsequent use. Secondly, the double-layer co-extrusion process of the insulating layer 30 and the sheath layer 40 can make the inner and outer sheaths in close contact without delamination under the action of high temperature and high pressure in the continuous vulcanization pipeline. During extrusion, the upper traction adopts a guide wheel type wire-paying traction device to avoid the flattening and deformation of the cable core caused by traditional crawler traction. A double-layer co-extrusion extrusion mold is used at the head of the machine, and the position of the mold is adjusted. When applicable, the distance between the middle mold and the outer mold is increased, thereby increasing the extrusion pressure of the continuous vulcanization rubber extruder, so that the sheath material tightly covers the cable surface, enhancing the stability and torsion resistance of the overall cable.

[0054] Furthermore, the 0.49 mm 8 series 5 type first aluminum alloy monofilament 52 is drawn from a 2 mm 8 series 5 type aluminum rod, and the 0.49 mm 6 series 5 type second aluminum alloy monofilament 62 is drawn from a 2 mm 6 series 5 type aluminum rod. Both the first aluminum alloy monofilament 52 and the second aluminum alloy monofilament 62 are subjected to an annealing process to achieve better elongation at break, tensile strength, and torsion resistance. The annealing processes of the first aluminum alloy monofilament 52 and the second aluminum alloy monofilament 62 are different and are carried out in different annealing furnaces; the conductor is annealed again as a whole after being assembled into a cable to achieve the requirements of high strength and high torsion resistance.

[0055] In summary, the comprehensive performance of the new type of aluminum alloy combined conductor wind energy resistant torsion flexible cable involved in the present application is far ahead of the traditional wind energy resistant torsion flexible cable, which greatly reduces the probability of broken wires in the outer layer of the cable conductor, while saving costs. It can better cope with the urgent needs of miniaturization of high-temperature resistant coils and realize the demand for a thin insulation layer 30 for high-temperature resistant conductors. While ensuring high performance, it meets the growing miniaturization and lightweight requirements of equipment, and can better promote the development and application of high-temperature resistant electromagnetic wires to higher-end fields.

[0056] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0057] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
