[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] As Figure 1 、 Figure 2 shown, the present utility model provides a new type of double-insulated cable, which includes a plurality of wire bundles 1 and a braided sleeve 2 for wrapping the plurality of wire bundles 1. Each wire bundle 1 includes an insulating sleeve 11 and a power line 12, and the insulating sleeve 11 is sleeved on the outer surface of the power line 12.

[0025] In this embodiment, an insulating sleeve 11 is sleeved on the outer surface of each power line 12, and then the outer sides of the plurality of wire bundles 1 are wrapped with a braided sleeve 2 to enhance the insulation performance of the cable, and a double-insulated protection system can be formed. And through the double-insulated design, that is, the double protection of the insulating sleeve 11 and the braided sleeve 2, the insulation performance of the cable has been greatly improved. It not only effectively prevents current leakage, but also greatly improves the safety of the cable and reduces risks such as electric shock and fire caused by insulation problems. In addition, the braided sleeve 2 has excellent wear resistance and tensile resistance, and can protect the internal wire bundles 1 from damage by external mechanical forces, so that the cable can still maintain good performance in complex wiring environments, such as bending, stretching or twisting. In addition, the braided sleeve 2 makes the cable have better flexibility and bendability, which is convenient for installation and use in various complex wiring environments.

[0026] As Figure 1 、 Figure 2 shown, in this embodiment, the plurality of wire bundles 1 are arranged side by side, which can make the wiring work more neat and orderly. It can not only reduce the chaos and entanglement of wires, make the overall wiring structure clearer, but also help to reduce the installation difficulty and improve the wiring efficiency. In addition, since the wire bundles 1 are arranged side by side, the subsequent management and maintenance of the cable become more convenient, enabling maintenance personnel to quickly identify specific wire bundles 1, thereby performing necessary inspections and repairs, improving work efficiency, and the side-by-side arranged wire bundles 1 can make more effective use of space, especially when wiring in a limited space, the space can be maximally utilized and space waste can be reduced. At the same time, through reasonable side-by-side arrangement, the distance between the wire bundles 1 can be ensured to be appropriate, avoiding damage or safety hazards caused by friction or extrusion between the wire bundles 1. Of course, in actual design, the distribution method of the plurality of wire bundles 1 can be designed according to actual needs.

[0027] As Figure 1 、 Figure 2As shown, in this embodiment, the number of wire harnesses 1 can be designed to be four, and the four wire harnesses 1 are arranged side by side.

[0028] In this embodiment, the braided sleeve 2 can be designed to be made of a flame-retardant material. Then, when the braided sleeve 2 encounters a fire source, it is not easy to burn. Even if it burns, it will quickly go out by itself, and the flame will not spread along the pipeline. In addition, the braided sleeve 2 made of the flame-retardant material also has characteristics such as impact resistance, heat resistance, corrosion and pest resistance, and good insulation performance, enabling it to play an excellent protective role in various occasions. In addition, the flame-retardant material of the braided sleeve 2 can be designed to be made of materials such as nylon and polyester (PET). In actual design, the material of the braided sleeve 2 can be designed according to actual needs.

[0029] In this embodiment, the insulating sleeve 11 is made of a radiation-crosslinked polyolefin material. Through a specific radiation crosslinking technology, the molecular structure inside the material is optimized, thereby greatly improving its physical properties. The radiation-crosslinked polyolefin material has excellent insulation performance, heat resistance, mechanical properties, and chemical stability. Sheathing the insulating sleeve 11 made of the radiation-crosslinked polyolefin material on the outer surface of the power cord 12 can effectively prevent risks such as current leakage and electric shock, ensuring the safe use of the wire. At the same time, the good heat resistance of the radiation-crosslinked polyolefin material also ensures that the insulating sleeve 11 can still maintain a stable working state in a high-temperature environment, is not easy to deform or melt, enabling the wire harness 1 to adapt to various harsh working environments and ensuring the long-term stable operation of the equipment. In addition, the high mechanical strength and wear resistance of the radiation-crosslinked polyolefin material enable the insulating sleeve 11 to resist damage from external mechanical forces and protect the power cord 12 from being damaged, while the excellent chemical stability of the radiation-crosslinked polyolefin material can prevent chemical corrosion and aging phenomena from occurring, further extending the service life of the wire harness 1.

[0030] In this embodiment, the inner diameter of the insulating sleeve 11 is 1 mm to 28 mm. The inner diameter of the insulating sleeve 11 can be designed to be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 12 mm, 14 mm, 16 mm, 20 mm, 22 mm, 25 mm, 28 mm. In actual design, the inner diameter of the insulating sleeve 11 can be designed according to actual needs.

[0031] In this embodiment, the wall thickness of the insulating sleeve 11 is 0.16 mm to 0.29 mm. The wall thickness of the insulating sleeve 11 can be designed as 0.16 mm, 0.18 mm, 0.19 mm, 0.20 mm, 0.21 mm, 0.22 mm, 0.23 mm, 0.24 mm, 0.25 mm, 0.26 mm, 0.28 mm, 0.29 mm. In actual design, the wall thickness of the insulating sleeve 11 can be designed according to actual needs.

[0032] In this embodiment, an insulating sleeve 11 is sleeved on the outer surface of each power line 12, and then a braided sleeve 2 is wrapped around the outside of multiple wire harnesses 1 to enhance the insulation performance of the cable, and a double-layer insulation protection system can be formed.
