Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1-2 As shown, a photovoltaic high temperature resistant silicone rubber wire configured for a photovoltaic mobile power station proposed in one embodiment of the utility model comprises a wire core 1, an electromagnetic shielding tape 2 is wound around the wire core 1, the electromagnetic shielding tape 2 is covered by a branching sleeve 3, the branching sleeve 3 is a rubber sleeve, the branching sleeve 3 is wrapped in a binding sleeve 4, the branching sleeve 3 is provided with a filler 5 in the middle of the binding sleeve 4, the binding sleeve 4 is a polyester fiber sleeve, the outside of the binding sleeve 4 is covered with a sheath 6, and the sheath 6 is a silicone sleeve;

[0022] Wire core 1: As the main transmission channel of current, tinning can enhance conductivity and oxidation resistance. Electromagnetic shielding tape 2: Reduce the impact of electromagnetic interference on signal transmission.

[0023] The branching sleeve 3 is a rubber sleeve, which protects and fixes the electromagnetic shielding belt 2 and also provides certain insulation performance.

[0024] Restraint sleeve 4: A polyester fiber sleeve tightly wraps the branching sleeve 3 and the internal structure to enhance the overall stability and tensile resistance.

[0025] Filler 5: fills the space, supports the internal structure, enhances the overall strength and stability of the cable, and provides certain heat insulation and insulation properties.

[0026] Sheath 6: Silicone sheath, function: providing the outermost layer of protection, with good high temperature resistance, wear resistance, insulation and other properties, protecting the internal structure from damage by the external environment.

[0027] First, prepare the ultra-fine tinned copper core material, and use a specific process to wind multiple tinned copper cores to form a wire core 1. Then, the electromagnetic shielding tape 2 is wrapped on the wire core 1 in an oblique winding manner. The electromagnetic shielding tape 2 can be a metal foil or a braided tape to ensure that it fits tightly and has a good electromagnetic shielding effect. Then, the electromagnetic shielding tape 2 is wrapped with a rubber branch sleeve 3 to fix and protect it. Then, the branch sleeve 3 is placed in a binding sleeve 4 made of polyester fiber, so that the binding sleeve 4 tightly wraps the branch sleeve 3 and the internal structure. Fill the middle of the binding sleeve 4 with fillers 5 such as rock wool, glass fiber, asbestos, rubber powder, plastic particles, and mica powder, and fill them reasonably according to actual needs. Finally, a silicone sleeve is extruded on the outermost layer of the entire cable to form a sheath 6, and it is tightly combined with the internal structure through a specific molding process, so that the manufacture of the entire cable is completed. During the manufacturing process, it is necessary to strictly control the process parameters and quality of each link to ensure that the cable has good performance and quality.

[0028] like Figure 1 As shown, in some embodiments, the wire core 1 is an ultra-fine tinned copper core, and the wire core 1 is formed by winding multiple wires; the wire core 1 adopts an ultra-fine tinned copper core, and these ultra-fine tinned copper cores are intertwined with each other through a specific winding process. The winding method of multiple ultra-fine tinned copper cores is carefully designed to ensure that the current can be evenly distributed and transmitted, while enhancing the overall mechanical strength and flexibility of the wire core 1. This multi-winding structure can reduce resistance and improve conductivity, and the tinning treatment further improves the oxidation resistance and conductivity of the copper core, so that the cable can maintain stable and reliable performance during long-term use, and better adapt to various complex working environments and electrical requirements.

[0029] like Figure 2As shown, in some embodiments, the electromagnetic shielding tape 2 is a metal foil or a braided tape, and both are flat tapes, which are wrapped around the wire core 1 in an oblique winding manner; the metal foil has good continuity and shielding effect, and can effectively block the intrusion of external electromagnetic interference; while the braided tape may have certain flexibility and adaptability while providing shielding. Through this specific oblique winding process, the electromagnetic shielding tape 2 is tightly combined with the wire core 1, which not only ensures the effective shielding of electromagnetic signals, but also enhances the stability and durability of the overall structure of the cable, ensures the accuracy and reliability of the cable when transmitting signals and currents, and reduces the adverse effects of electromagnetic interference on the performance of the cable.

[0030] like Figure 1 As shown, in some embodiments, the filler 5 is rock wool, glass fiber, asbestos, rubber powder, plastic particles, mica powder; the filler 5 contains a variety of different materials. Rock wool has good heat insulation and fire resistance, which can improve the safety and stability of the cable to a certain extent; glass fiber has high strength and can play a role in strengthening and supporting; asbestos also has certain heat resistance and heat insulation properties; rubber powder can increase the elasticity and buffering performance of the filler 5; mica powder performs well in electrical insulation and heat resistance. These different materials together constitute the filler 5, which cooperate with each other and are reasonably matched according to actual needs, providing a substantial filling effect for the inside of the cable, ensuring the structural integrity of the cable, and also giving the cable advantages in different performance aspects, such as heat insulation, insulation, strength, etc., so that the cable can better adapt to various working conditions and environmental requirements.

[0031] like Figure 2 As shown, in some embodiments, the plastic particles are polyethylene (PE) particles and polypropylene (PP) particles. Polyethylene (PE) particles have good chemical stability, low temperature resistance and certain flexibility, and can play the role of filling space and enhancing buffering in the filler 5. Polypropylene (PP) particles have good heat resistance and mechanical properties, and can increase the strength and rigidity of the filler 5. These two types of plastic particles have their respective functions in the filler 5, and are reasonably allocated according to the specific use scenarios and performance requirements of the cable.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
