Description

Technical Field

[0001] The present application relates to the technical field of wires and cables, and in particular to a high-efficiency and energy-saving wire and cable. Background Art

[0002] Electrical wires are conductors used to transmit electrical energy. They are classified as bare wire, magnet wire, and insulated wire. Bare wire lacks insulation and includes copper and aluminum flat wire, overhead stranded wire, and various profiles (such as profiled wire, busbars, copper and aluminum busbars, etc.). It is primarily used for outdoor overhead wiring and indoor busbars and switch boxes. Magnet wire is an insulated conductor that generates a magnetic field when energized or induces current in a magnetic field. It is primarily used for winding motors, transformers, and other related electromagnetic equipment. Its conductor, primarily copper, should have a thin insulation layer and excellent electrical and mechanical properties, as well as resistance to heat, moisture, and solvents. Different insulation materials can achieve different properties.

[0003] In modern power transmission systems, wires and cables are key carriers of power transmission, and their performance directly affects the efficiency and energy consumption of power transmission. Traditional wires and cables present numerous problems during use. For one thing, the conductivity of the conductor material needs to be improved, resulting in significant power loss during transmission. Furthermore, the cable's structural design is often irrational, resulting in poor heat dissipation, which causes the cable to heat up after extended operation. This not only increases energy consumption but also potentially impacts the cable's service life and operational safety. Summary of the Invention

[0004] In order to solve the problems raised by the above background technology, the present application provides a high-efficiency and energy-saving wire and cable.

[0005] The present application provides a high-efficiency energy-saving wire and cable adopting the following technical solutions:

[0006] A high-efficiency energy-saving electric wire and cable comprises a conductor layer, a first insulating layer, a heat dissipation layer, a shielding layer, a second insulating layer and a protective layer which are arranged in sequence from the inside to the outside.

[0007] Preferably, the conductor layer is made of high-purity oxygen-free copper with a purity of not less than 99.99%, and is formed by twisting multiple strands of fine copper wires, with a twisting pitch of 8-12 times the conductor diameter.

[0008] Preferably, the first insulating layer is made of low-density polyethylene material with a density of 0.910-0.925 g / cm³ and a thickness of 0.8-1.2 mm.

[0009] Preferably, the heat dissipation layer is composed of a composite of a graphene heat dissipation film and an aluminum foil layer, the graphene heat dissipation film is located on the inner side, and the aluminum foil layer is located on the outer side, with a thickness of 0.3-0.5 mm.

[0010] Preferably, the shielding layer is a nickel-plated copper braided mesh with a braiding density of not less than 90% and a mesh diameter of 0.5-1.0 mm.

[0011] Preferably, the second insulating layer is made of silicone rubber material with a Shore hardness of 50-60A and a thickness of 1.0-1.5 mm.

[0012] Preferably, the protective layer is made of modified polyvinyl chloride material, added with nano-scale titanium dioxide and antioxidants, has a thickness of 1.5-2.0 mm, and is provided with wavy grooves on the outer surface.

[0013] In summary, this application has the following beneficial technical effects:

[0014] 1. By using high-purity oxygen-free copper as the conductor layer material, the conductor resistance is reduced, reducing the heat generated when the current passes through, thereby reducing power loss. The twisting method of multiple fine copper wires further improves the conductor's flexibility and conductivity.

[0015] 2. The first insulation layer is made of low-density polyethylene material, which has good insulation performance and low thermal conductivity, can reduce the transfer of heat to the outside world, and at the same time provide good insulation protection for the conductor.

[0016] 3. The heat dissipation layer is composed of a composite of graphene heat dissipation film and an aluminum foil layer. The graphene heat dissipation film has excellent thermal conductivity and can quickly dissipate the heat generated by the conductor. The aluminum foil layer reflects heat and enhances the strength of the heat dissipation layer, effectively reducing the operating temperature of the cable and improving energy utilization efficiency.

[0017] 4. The shielding layer adopts nickel-plated copper braided mesh, which can effectively shield electromagnetic radiation and reduce the energy loss caused by electromagnetic radiation. At the same time, it improves the anti-interference ability of the cable and ensures the stability of power transmission.

[0018] 5. The second insulation layer is made of silicone rubber material, which has good high temperature resistance and insulation performance. It can work stably at higher temperatures, further improving the reliability of the cable.

[0019] 6. The protective layer is made of modified polyvinyl chloride material, with the addition of nano-level titanium dioxide and antioxidants, which improves the weather resistance, aging resistance and UV resistance of the protective layer, extending the service life of the cable. The wavy groove design on the outer surface increases the contact area between the protective layer and the outside world, which is conducive to heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following is combined with Figure 1-2 This application is described in further detail.

[0024] The embodiment of the present application discloses a high-efficiency energy-saving wire and cable. Figure 1-2 A high-efficiency and energy-saving wire and cable includes a conductor layer 1, a first insulating layer 2, a heat dissipation layer 3, a shielding layer 4, a second insulating layer 5 and a protective layer 6.

[0025] Conductor layer 1 is made of high-purity oxygen-free copper with a purity of at least 99.99%. Multiple strands of fine copper wire 7 are twisted together at a twist pitch of 8-12 times the conductor diameter. This conductor has extremely low resistance, effectively reducing heat loss during current transmission.

[0026] The first insulating layer 2 is made of low-density polyethylene (LDPE) with a density of 0.910-0.925 g / cm³. It is extruded over the outer surface of the conductive layer 1 and has a thickness of 0.8-1.2 mm. LDPE has excellent insulation properties and low thermal conductivity, preventing current leakage and reducing heat transfer.

[0027] The heat dissipation layer 3 is composed of a composite of graphene heat dissipation film and aluminum foil. The graphene heat dissipation film is first applied to the outside of the first insulating layer 2, and then the aluminum foil is wrapped around the graphene heat dissipation film. The thickness of the heat dissipation layer 3 is 0.3-0.5 mm. The graphene heat dissipation film quickly dissipates heat generated by the conductor layer 1, while the aluminum foil reflects heat and enhances the strength of the heat dissipation layer 3. The combination of the two significantly improves the cable's heat dissipation efficiency.

[0028] Shielding layer 4 is a nickel-plated copper braid with a weave density of at least 90% and a mesh diameter of 0.5-1.0 mm. Wrapping the nickel-plated copper braid around the heat dissipation layer 3 effectively shields electromagnetic radiation, reduces energy loss, and improves the cable's anti-interference capabilities.

[0029] The second insulating layer 5 is made of silicone rubber with a Shore hardness of 50-60A. It is extruded over the shielding layer 4 and has a thickness of 1.0-1.5 mm. Silicone rubber has excellent high-temperature resistance and insulation properties, ensuring stable operation in high-temperature environments and further ensuring the cable's insulation.

[0030] Protective layer 6 is made of modified polyvinyl chloride (PVC) with nano-scale titanium dioxide and antioxidants added. It is extruded over the outer surface of second insulating layer 5 and has a thickness of 1.5-2.0 mm. Wave-shaped grooves 8 are provided on the outer surface of protective layer 6, increasing the heat dissipation area and improving its weather resistance, aging resistance, and UV resistance.

[0031] The implementation principle of a high-efficiency, energy-saving wire and cable in the embodiment of this application is as follows: First, a high-purity oxygen-free copper conductor layer 1 is prepared and its performance is improved by twisting multiple strands of fine copper wire 7; then, a first insulating layer 2, a heat dissipation layer 3, a shielding layer 4, a second insulating layer 5, and a protective layer 6 are sequentially coated. The materials and structural design of each layer are designed to reduce energy consumption and improve energy utilization efficiency. During power transmission, the conductor layer 1 reduces resistance loss, the heat dissipation layer 3 dissipates heat in a timely manner, the shielding layer 4 reduces electromagnetic radiation loss, the first insulating layer 2 and the second insulating layer 5 ensure insulation, and the protective layer 6 protects the overall cable structure and extends its service life, thereby achieving high-efficiency and energy-saving operation of the cable.
