Technical Field
[0001] This utility model belongs to the field of wire sheath technology, specifically an anti-aging insulating silicone rubber wire sheath. Background Technology
[0002] Electric wires are typically made up of several or groups of conductors twisted together, resembling a rope. Each group of conductors is insulated from each other and is often twisted around a central core. The entire wire is covered with an insulated outer sheath. Electric wires are mostly installed in the air, underground, or underwater for telecommunications or power transmission.
[0003] The outer sheath of an electrical wire is an important component of the wire. It is generally a tubular structure used to protect and insulate the wire core.
[0004] In some harsh climates, the outer sheath of electrical wires is prone to aging and damage due to high temperatures and prolonged exposure to ultraviolet radiation, which affects the service life of the wires. Therefore, an anti-aging insulating silicone rubber wire sheath is proposed to address the above problems. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The anti-aging insulating silicone rubber wire sheath of this utility model includes an outer sheath body. The outer sheath body includes an internal protective mechanism and an external anti-aging mechanism. The internal protective mechanism includes a retainer disposed inside the outer sheath body. The retainer is disposed along the extension direction of the outer sheath body. A plurality of wire grooves are evenly disposed on the retainer. Wire cores are disposed on the plurality of wire grooves respectively. A shielding insulation layer is disposed on the outside of the wire cores. A heat insulation filling layer is disposed on the outside of the wire cores and the retainer. The external anti-aging mechanism is disposed on the outside of the heat insulation filling layer.
[0007] Preferably, the external anti-aging mechanism includes an insulating silicone rubber liner, a nano anti-aging layer, a chlorosulfonated polyethylene sunscreen layer, and a polytetrafluoroethylene wear-resistant layer, which are sequentially arranged on the outside of the heat insulation filling layer.

Through the structural design of the external anti-aging mechanism of the sheath body, the anti-aging properties of the wire sheath are improved. The insulating silicone rubber liner has good insulation and heat insulation properties. The nano-anti-aging layer protects the wire sheath from the attack of hot electrons, improving its anti-aging properties. The chlorosulfonated polyethylene sunscreen layer has good UV resistance and oxidation resistance, significantly reducing UV damage to the wire sheath and thus improving its anti-aging properties.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1-4 This utility model provides an anti-aging insulating silicone rubber wire sheath, including an outer sheath body. The outer sheath body includes an internal protective mechanism and an external anti-aging mechanism. The anti-aging properties of the wire sheath are improved by the external anti-aging mechanism of the outer sheath body, and the compressive strength of the wire core 3 is improved by the internal protective mechanism of the outer sheath body. The internal protective mechanism includes a retainer 1 disposed inside the outer sheath body. The retainer 1 is disposed along the extension direction of the outer sheath body. Multiple wire grooves 2 are evenly disposed on the retainer 1. Wire cores 3 are disposed on the multiple wire grooves 2 respectively. A shielding insulation layer 4 is disposed on the outside of the wire core 3. The shielding insulation layer 4 can ensure that the transmitted current or electromagnetic waves or light waves only travel along the conductor and do not flow to the outside. The potential on the conductor (i.e., the potential difference formed on the surrounding objects, i.e., voltage) can be isolated. A heat insulation filling layer 5 is disposed on the outside of the wire core 3 and the retainer 1. An external anti-aging mechanism is disposed on the outside of the heat insulation filling layer 5.
[0026] Furthermore, such as Figure 1 and Figure 3As shown, the external anti-aging mechanism includes an insulating silicone rubber liner 6, a nano-anti-aging layer 7, a chlorosulfonated polyethylene sunscreen layer 8, and a polytetrafluoroethylene wear-resistant layer 9 sequentially arranged outside the heat-insulating filling layer 5. The insulating silicone rubber liner 6 provides good insulation and heat insulation. The nano-anti-aging layer 7 is synthesized from silica and graphene nanofillers and cross-linked polyethylene, forming an anti-aging layer. The influence of these properties on the performance of the anti-aging layer was theoretically studied. Density functional theory was used, and through Bader charge analysis, interfacial adsorption energy, and chemical reaction transition state calculations, the attraction of hot electrons by different nanofillers was compared, the strength of the ability to restrict the movement of cross-linked polyethylene chains was assessed, and the possibility of chemical hydrogen migration was investigated. Finally, a selection process was conducted. Potential nanofillers were identified to improve the anti-aging properties of cross-linked polyethylene. The interaction between silica nanofillers and cross-linked polyethylene revealed that fully hydroxylated, nitrogen-doped, and natively oxygen-vacant silica can all improve the anti-aging properties of cross-linked polyethylene to varying degrees, protecting the wire sheath from the attack of hot electrons and enhancing its anti-aging properties. The chlorosulfonated polyethylene sunscreen layer 8 possesses good UV resistance and antioxidant properties, significantly reducing UV damage to the wire sheath and thus improving its anti-aging properties. The polytetrafluoroethylene (PTFE) wear-resistant layer 9 exhibits high corrosion resistance, making the wire sheath less susceptible to corrosion by acids and alkalis, thereby enhancing the anti-aging properties of the wire sheath.
[0027] Furthermore, such as Figure 1 and Figure 3 As shown, the thickness of the insulating silicone rubber liner 6 is 3-5 mm, and the thickness of the nano anti-aging layer 7 is 1.5 times that of the insulating silicone rubber liner 6, thereby improving the anti-aging properties of the wire sheath.
[0028] Furthermore, such as Figure 2 and Figure 3 As shown, multiple sets of nylon ropes 10 are uniformly embedded in the polytetrafluoroethylene wear-resistant layer 9. Polytetrafluoroethylene has good chemical stability, which improves the corrosion resistance of the wire sheath and makes it difficult for the wire sheath to be corroded by acid and alkali substances. Furthermore, the nylon ropes 10 embedded in the polytetrafluoroethylene wear-resistant layer 9 further enhance the wear resistance of the polytetrafluoroethylene wear-resistant layer 9.
[0029] Furthermore, such as Figure 1 and Figure 4 As shown, a reinforcing rib 11 is provided in the retainer 1 along the extension direction of the outer sheath body. The reinforcing rib 11 is made of flexible material and the density of the reinforcing rib 11 is greater than the density of the retainer 1, thereby improving the support of the retainer 1 for the wire core 3, and thus improving the impact protection of the wire core 3 in the outer sheath of the wire.
[0030] Furthermore, such as Figure 1 and Figure 4As shown, the wire groove 2 is provided with anti-slip texture 12 to improve the stability of the wire core 3 in the retainer 1 and prevent the wire core 3 in the wire sheath from moving due to external impact.
[0031] Working Principle: The external anti-aging structure of the outer sheath enhances the aging resistance of the wire sheath. The insulating silicone rubber liner 6 provides good insulation and heat insulation. The nano-anti-aging layer 7 protects the wire sheath from thermal electron attack, further improving its aging resistance. The chlorosulfonated polyethylene sunscreen layer 8 has good UV resistance and oxidation resistance, significantly reducing UV damage to the wire sheath and thus improving its aging resistance. The high corrosion resistance of PTFE in the PTFE wear-resistant layer 9 makes the wire sheath less susceptible to corrosion by acids and alkalis, further enhancing its aging resistance. Furthermore, nylon rope 10 is embedded in the PTFE wear-resistant layer 9 to improve its wear resistance and extend the service life of the wire sheath.
[0032] Through the internal protective mechanism of the outer sheath, the wire core 3 is stably placed in the wire groove 2 of the retainer 1, preventing the wire core 3 in the wire sheath from moving due to external impact. The retainer 1 is provided with reinforcing ribs 11 to improve the support of the retainer 1 for the wire core 3 and improve the impact protection of the wire core 3 in the wire sheath. In addition, a heat insulation filling layer 5 is provided on the outside of the wire core 3 and the retainer 1 to improve the protection of the wire core.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
