Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a Litz wire for a stainless steel strip with flexible support to reinforce a magnet. Background Technology

[0002] In the field of magnet technology, especially in applications requiring reinforced magnet structures while maintaining flexible support, traditional cables often struggle to meet the demands of withstanding certain mechanical stresses while maintaining good conductivity and insulation. Traditional cables have a simple structure, with the conductor typically composed of multiple strands of fine wire simply twisted together. This structure is prone to strand breakage and insulation damage when subjected to mechanical stresses such as bending or stretching, leading to decreased electrical performance and even safety hazards.

[0003] Especially in specialized applications, such as flexible support systems requiring enhanced magnets, cables not only need excellent conductivity but also sufficient mechanical strength and flexibility to withstand complex installation environments and long-term stress variations. Furthermore, traditional cables often struggle to meet performance requirements in terms of flame retardancy, abrasion resistance, and aging resistance when selecting insulation and sheathing materials. Therefore, the market urgently needs a new type of cable. Utility Model Content

[0004] To address some of the problems existing in the prior art, this utility model provides a Litz wire for flexible support and reinforcement of magnets with stainless steel strip. Through reasonable structural design, it effectively improves the conductivity, corona resistance, support and reinforcement performance, and safety performance of the wire, making it suitable for use in strong magnetic environments.

[0005] To achieve the above objectives, this utility model provides a Litz wire for a stainless steel strip flexible support reinforced magnet, comprising a Litz wire body, wherein the Litz wire body includes a conductor portion disposed inside the Litz wire body, an insulating portion disposed outside the conductor portion, a sheath portion disposed outside the insulating portion, and a plurality of integrated cables disposed sequentially on the conductor portion.

[0006] As a further improvement of this utility model, in order to help disperse current, reduce electromagnetic interference, improve transmission efficiency, further balance the current load of each cable strand, and extend the service life of the cable, the integrated cable is composed of several primary cables. The primary cables are arranged in the form of 20 or more even-numbered strands and are arranged in two rows. Each primary cable strand is fully transposed.

[0007] As a further improvement of this utility model, in order to effectively resist corona discharge and improve the insulation performance and safety of the cable, the primary cable is provided with 19 strands of corona-resistant enameled wire. The outer surface of the corona-resistant enameled wire is uniformly coated with an internal insulation layer, and the corona-resistant enameled wire is arranged in a 1+6+12 structure.

[0008] As a further improvement of this utility model, in order to provide additional flexible support, enhance the tensile strength and torsional resistance of the cable, and help reduce the interference of external electromagnetic fields on the internal current transmission of the cable, a stainless steel strip is embedded between the two rows of integrated cables.

[0009] As a further improvement of this utility model, in order to further improve the reliability and durability of the insulation layer and ensure the stable operation of the cable in harsh environments, the insulation part is composed of an aromatic polyimide composite film and a self-adhesive glass fiber double layer.

[0010] As a further improvement of this utility model, in order to enhance the stability and safety of the cable during use, the sheath is set on the outermost layer and is made of flame-retardant, wear-resistant, and anti-aging halogen flame-retardant polyolefin polymer composite material, and the surface is also provided with an anti-slip texture structure.

[0011] In operation, this invention incorporates several sets of integrated cables within the Litz wire body, which constitute the main conductive portion of the Litz wire. Each set of integrated cables consists of several primary cables arranged in even numbers (20 or more strands) in two rows. Each primary cable undergoes full transposition and is reinforced with a stainless steel strip, which helps reduce eddy current losses and electromagnetic interference during current transmission, thereby improving current transmission efficiency.

[0012] The primary cable contains 19 strands of corona-resistant enameled wire. The outer surface of these wires is uniformly coated with an internal insulation layer to enhance their insulation performance and corona resistance. The corona-resistant enameled wires are arranged in a 1+6+12 structure, which helps improve the cable's flexibility and abrasion resistance while ensuring stable current transmission.

[0013] A stainless steel strip is embedded between the two rows of integrated cables. This design not only provides additional mechanical support, enhancing the overall strength and stability of the Litz cable, but also helps reduce deformation and damage to the cable when it is bent or stressed.

[0014] The insulation is composed of a double layer of aramid polyimide composite film and self-adhesive glass fiber. This material combination has excellent insulation and heat resistance properties, which can ensure the normal operation of the Leeds line in harsh environments.

[0015] The outermost sheath is made of a flame-retardant, wear-resistant, and anti-aging halogenated flame-retardant polyolefin polymer composite material. This material not only has excellent physical and chemical properties but also prevents hazards such as fire and corrosion. The sheath surface also features an anti-slip textured structure, which helps prevent the Litz wire from slipping or sliding during use, improving the ease of installation and use.

[0016] The beneficial effects of this utility model are as follows:

[0017] Improve current transmission efficiency:

[0018] By employing fully transposed primary cables and optimized cable arrangement design, eddy current losses and electromagnetic interference during current transmission are reduced, thereby improving current transmission efficiency.

[0019] Enhance cable stability and durability:

[0020] The embedded stainless steel strip provides additional mechanical support, enhancing the overall strength and stability of the Litz wire, enabling it to withstand greater bending and stress, and reducing the risk of deformation and damage.

[0021] The use of corona-resistant enameled wire and the coating of the internal insulation layer enhance the insulation performance and corona resistance of the cable, extending its service life.

[0022] Improve cable flexibility:

[0023] The corona-resistant enameled wire adopts a 1+6+12 structure arrangement, which makes the cable more flexible, easy to install and bend, and adaptable to different application scenarios.

[0024] Improve thermal stability and safety:

[0025] The sheath is made of flame-retardant, wear-resistant, and anti-aging halogen flame-retardant polyolefin polymer composite material, which effectively prevents dangerous situations such as fire and corrosion, and improves the safety of the cable.

[0026] Optimize insulation performance:

[0027] The insulation is composed of a double layer of aramid polyimide composite film and self-adhesive glass fiber. This material combination has excellent insulation and heat resistance properties, ensuring the normal operation of the Leeds line in harsh environments.

[0028] Improve installation and ease of use:

[0029] The sheath surface features an anti-slip textured structure, which helps prevent the Litz wire from slipping or sliding during use, improving the ease of installation and use. Attached Figure Description
