Description

Technical Field

[0001] This utility model belongs to the field of new energy technology, specifically relating to a high-temperature resistant and flame-retardant cable for new energy equipment. Background Technology

[0002] New energy equipment mainly includes power generation system equipment, energy storage equipment, charging and discharging devices, and core components of new energy vehicles, covering the entire chain of energy production, storage, and application. Cables are generally used to supply power to new energy equipment. A search revealed that application number "CN202123217372.4" discloses "a high-temperature resistant cable for new energy batteries," which describes a method where "a shielding layer is wrapped with an isolation layer formed by flame-retardant polyester composite tape, and a high-temperature resistant, high-tear-resistant silicone rubber is extruded over the isolation layer to form an outer sheath. High-temperature resistant quartz wire is then woven into the outer sheath to form a high-temperature resistant layer, giving the cable good flame retardant properties, high-temperature resistance, and good physical and mechanical properties." While wrapping the shielding layer with an isolation layer formed by flame-retardant polyester composite tape, extruding the isolation layer with high-temperature resistant, high-tear-resistant silicone rubber to form an outer sheath, and weaving high-temperature resistant quartz wire into the outer sheath to form a high-temperature resistant layer does indeed give the cable good flame retardant properties, high-temperature resistance, and good physical and mechanical properties, the above-mentioned document still has the following problems in actual use:

[0003] In actual use, the lack of a high-temperature resistant and flame-retardant layer results in poor performance, and the cable itself lacks protection during use, making it prone to damage.

[0004] Therefore, providing a cable that can achieve high temperature resistance and flame retardancy, and also has the function of protecting the cable body, is highly applicable. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature resistant and flame-retardant cable for new energy equipment, in order to solve the above-mentioned technical problems.

[0006] This utility model provides a high-temperature resistant and flame-retardant cable for new energy equipment, including a cable body, a high-temperature resistant and flame-retardant component, and a protective component.

[0007] The cable body has a conductor in the middle of its inner wall;

[0008] The high-temperature resistant and flame-retardant component includes an insulating fireproof layer disposed on the outer wall of the conductor, a high-temperature resistant layer disposed on the outer wall of the insulating fireproof layer, a first flame-retardant layer disposed on the outer wall of the high-temperature resistant layer, and a second flame-retardant layer disposed on the outer wall of the first flame-retardant layer.

[0009] The protective component includes a shielding layer disposed on the outer wall of the second flame-retardant layer, an impact-resistant layer disposed on the outer wall of the shielding layer, an environmental protection layer disposed on the outer wall of the impact-resistant layer, and an auxiliary functional layer disposed on the outer wall of the environmental protection layer, wherein the auxiliary functional layer is a wear-resistant coating.

[0010] In one embodiment of this utility model, the insulating and fireproof layer is made of ceramicized silicone rubber.

[0011] In one embodiment of this utility model, the high-temperature resistant layer is made of magnesium oxide.

[0012] In one embodiment of this utility model, the first flame-retardant layer and the second flame-retardant layer are made of mica tape and halogen-free flame-retardant material, respectively.

[0013] In one embodiment of this invention, the shielding layer is made of a metallized polyimide film.

[0014] In one embodiment of this utility model, the impact-resistant layer is made of tin-plated copper wire.

[0015] In one embodiment of this utility model, the environmental protection layer is made of weather-resistant halogen-free flame-retardant polyurethane.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1) The ceramicized silicone rubber can be used for insulation in daily use. When exposed to open flame, the ceramicized silicone rubber will be dried to form a ceramic armor to protect the conductor. The high-temperature resistant layer can be used to effectively block the high temperature generated by open flame by utilizing the high-temperature resistant properties of magnesium oxide. The first and second flame-retardant layers can be used to form double flame-retardant protection by combining mica tape and halogen-free flame-retardant materials, thereby improving the flame-retardant performance and achieving high-temperature flame retardancy.

[0018] 2) During use, the polyimide film can shield external electromagnetic interference, enabling the cable body to operate more stably. The impact-resistant layer allows the tinned copper wire and galvanized steel wire to bear most of the tensile force, greatly enhancing the tensile strength of the cable body. The environmental protection layer utilizes halogen-free flame-retardant polyurethane to protect the cable body with its wear-resistant, oil-resistant, acid and alkali corrosion-resistant, and UV aging-resistant properties. The auxiliary functional layer allows the wear-resistant coating to further increase wear resistance, thereby achieving the purpose of protecting the cable body. Attached Figure Description

Furthermore, the first flame-retardant layer 230 and the second flame-retardant layer 240 combine mica tape and halogen-free flame-retardant materials to form double flame-retardant protection, improving flame-retardant performance and achieving the purpose of high-temperature flame retardancy.

[0045] In use, the included insulating and fireproof layer 210 utilizes the properties of ceramicized silicone rubber for insulation during daily use. When exposed to open flame, the ceramicized silicone rubber dries and forms a ceramic armor layer, protecting the conductor 110. The high-temperature resistant layer 220, utilizing the high-temperature resistance of magnesium oxide, effectively blocks the high temperatures generated by open flames. The first flame-retardant layer 230 and the second flame-retardant layer 240, combined with mica tape and halogen-free flame-retardant materials, form a double flame-retardant protection, improving flame-retardant performance and achieving high-temperature flame retardancy. Finally, the included shielding layer 310... The cable body 100 is designed to be shielded from external electromagnetic interference using a polyimide film, enabling more stable operation. The impact-resistant layer 320 allows for the use of tin-plated copper wire and galvanized steel wire to absorb most of the tensile force, significantly enhancing the tensile strength of the cable body 100.
