[0002] A silver-plated wire is a wire with a layer of pure silver plated on the surface of a copper wire or other conductive material. It has good electrical conductivity and good corrosion resistance. It is generally used in high-temperature cables, micro cables, aerospace cables, and transformers, motors, generators, and other electrical equipment. When in use, it is often wound in a coil, which can improve signal transmission quality, electrical performance, mechanical strength, and heat dissipation performance, etc.

[0003] At present, the heat dissipation performance of the high-temperature-resistant silver-plated winding wire is poor. It contains a large number of materials inside, and these materials are tightly wrapped together. When the silver-plated winding wire is in use, the heat generated is difficult to dissipate in a short time, which may cause damage to the silver-plated winding wire. At the same time, the surfaces of the silver-plated copper wires after winding are in contact with each other, thus reducing the heat dissipation efficiency of its surface. Summary of the Utility Model

[0004] The utility model provides a high-temperature-resistant silver-plated winding wire. By setting heat dissipation strips, the contact area between the silver-plated winding wire and air can be increased, so as to facilitate its rapid heat dissipation. At the same time, by setting partitions and connecting grooves, etc., the silver-plated copper wires after winding can be separated to avoid contact and affect the heat dissipation efficiency of its surface. In summary, the problems in the background technique are solved.

[0026] Reference Figures 1-3 , a high-temperature resistant silver-plated winding wire, including a winding wire body (1), a heat dissipation strip 2 is arranged on the surface of the winding wire body 1, and a partition 3 is arranged on the surface of the winding wire body 1; a plurality of connection grooves 301 in contact with the surface of the winding wire body 1 are equidistantly arranged on the surface of the partition 3, and a through groove 302 is arranged at the top of the connection groove 301. The heat dissipation strip 2 is convenient for increasing the contact area between the winding wire body 1 and the air, so as to facilitate heat dissipation. The connection grooves 301 inside the partition 3 are convenient for separating adjacent winding wire bodies 1 to prevent their surfaces from contacting each other and affecting the heat dissipation efficiency of their surfaces.

[0027] Furthermore, the width of the through groove 302 is smaller than the diameter of the winding wire body 1. It is determined whether to install the partition 3 according to the stretching condition of the winding wire body 1. If the winding wire body 1 is stretched relatively long and its surface does not contact, the winding wire body 1 can be taken out from the inside of the connection groove 301 through the through groove 302.

[0028] Furthermore, the heat dissipation strips 2 are annularly and equidistantly arranged on the surface of the winding wire body 1, and the heat dissipation strips 2 are silicone grease heat dissipation strips 2. The silicone grease heat dissipation strips 2 are convenient for increasing the contact area between the silver-plated winding wire body 1 and the air, so as to facilitate heat dissipation of its surface and improve the heat dissipation efficiency.

[0029] Furthermore, the inside of the winding wire body 1 includes a silver-plated copper wire 101, and a first insulating layer 102 is arranged on the surface of the silver-plated copper wire 101. A filler 103 is arranged outside the first insulating layer 102, and a second insulating layer 104, a waterproof layer 105, a tensile layer 106, an antioxidant layer 107 and an outer sleeve 108 are sequentially arranged on the surface of the filler 103. The waterproof layer 105 is made of rubber material, and the antioxidant layer 107 is made of high flame-retardant ceramized silicone rubber, which has good insulation performance, aging resistance, arc resistance, ablation resistance, high and low temperature resistance, etc.

[0030] Furthermore, the material of the first insulating layer 102 is alkali-free glass fiber yarn, and the second insulating layer 104 is heat-resistant silicone rubber. The high-temperature resistant silicone rubber has the advantages of high thermal stability, low heat release rate, non-toxicity, aging resistance, etc. The alkali-free glass fiber yarn is coated with silicone rubber on the surface, which has the properties of flame retardancy, heat insulation, heat preservation, anti-electricity, softness, etc.

[0031] Furthermore, the tensile layer 106 is aromatic polyamide fiber, and the tensile layer 106 is distributed in a grid shape. By setting the grid-shaped aromatic polyamide fiber, it has high tensile strength and wear resistance, etc.
