[0021] like Figure 1 and 2 As shown, the utility model provides a composite enameled wire, including a conductor 1 and a first insulating layer covering the outside of the conductor 1, which plays an insulating role and can prevent the influence of leakage. The conductor 1 is evenly arranged in a ring shape and is provided with multiple groups. The multiple groups of conductors 1 are wrapped inside by the second insulating layer 3. The second insulating layer 3 cooperates with the first insulating layer 101 to effectively improve the insulation effect. When one of the insulating layers is damaged, leakage can still be prevented. The gap between the multiple groups of conductors 1 and the second insulating layer 3 is filled with a fireproof filling layer 2, the outer layer of the second insulating layer 3 is provided with a heat dissipation layer 4, the outer layer of the heat dissipation layer 4 is provided with a shielding layer 5, the outer layer of the shielding layer 5 is provided with a flame retardant layer 6, and the outer layer of the flame retardant layer 6 is provided with a protective layer 7.

[0022] like Figure 2 As shown, the conductor 1 is made of copper-clad aluminum wire, which combines the excellent conductivity of copper and the light weight of aluminum, while overcoming the disadvantages of easy oxidation of aluminum, large contact resistance, and difficult welding of joints, while also reducing costs. The first insulating layer 101 is formed by spraying and covering with polyurethane insulating paint, and the polyurethane insulating paint has excellent electric shock resistance and chemical resistance.

[0023] like Figure 2 As shown, the fireproof filling layer 2 is composed of aluminum silicate, which is a man-made mineral and also a high-temperature heat-insulating material. Aluminum silicate filler has good fireproofing, heat preservation, heat insulation and sound absorption properties, and is suitable for high-temperature occasions, and is evenly filled in the gap between the wire 1 and the second insulating layer 3.

[0024] like Figure 2 As shown, the second insulating layer 3 is made of acrylic insulating paint sprayed on the rubber surface. Acrylic insulating paint has good electrical insulation performance and mechanical strength and is commonly used in insulating coatings of electronic components and cables.

[0025] like Figure 2 As shown, the heat dissipation layer 4 is made of graphite, which utilizes the high thermal conductivity and layered structure of graphite to achieve rapid diffusion and transfer of heat. It is thin, light, efficient, and suitable for use in limited spaces.

[0026] like Figure 2 As shown, the shielding layer 5 is made of metal nickel, specifically, it is formed by stretching the metal nickel into a thin film, which can prevent the internal circuit from being interfered by radio waves and electromagnetic waves.

[0027] like Figure 2 As shown, the flame retardant layer 6 is formed by mixing magnesium hydroxide and aluminum hydroxide, and the mixture of the two can enhance the flame retardant effect.

[0028] like Figure 2 As shown, the protective layer 7 is made of wear-resistant rubber composed of nitrile rubber and has good wear resistance and shock absorption performance.
