Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable-related technology, specifically relating to an irradiated rubber cross-linked polyethylene cable. Background Technology
[0002] Irradiated rubber cross-linked polyethylene (XLPE) cable is an advanced cable type that combines the advantages of radiation cross-linking technology and polyethylene insulation. This type of cable is typically used in high-voltage and high-temperature environments, possessing excellent electrical and mechanical properties. It is widely used in power transmission and distribution systems, especially in locations requiring high temperatures and high reliability.

[0003] However, the rubber sheath of traditional cables is of relatively poor quality, and after long-term use, the sheath may dry and crack, exposing the internal battery cells. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an irradiated rubber cross-linked polyethylene cable, including a cable sheath;
[0006] The cable sheath has multiple insulation layers a inside, and an insulation layer b is provided inside the cable sheath near the left side. Each of the multiple insulation layers a and insulation layers b has a battery cell a and a battery cell b inside.
[0007] Preferably, the insulating layer a is made of irradiated rubber to increase its high-temperature resistance.

[0015] Compared with the prior art, this utility model provides an irradiated rubber cross-linked polyethylene cable, which has the following beneficial effects:
[0016] 1. By improving the traditional cable sheath material to the existing irradiated rubber material, and improving the original core outer insulation material to cross-linked polyethylene material, the irradiated rubber has good high temperature resistance and can maintain performance at high temperatures, making it suitable for use in harsh environments. The cross-linked structure of cross-linked polyethylene further enhances its resistance to high temperatures, typically withstanding environments from 90 degrees Celsius to 120 degrees Celsius, and improves the cable's tensile strength and abrasion resistance, extending its service life.
[0017] 2. By installing an outer jacket, the cable can be moved to the bending area of the cable during use, thereby enhancing the cable's compressive and tensile strength, extending its service life, and providing additional protection, reducing the risk of cable breakage or insulation failure due to bending.

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] This utility model provides, for example Figure 1-3 The illustrated irradiated rubber cross-linked polyethylene cable includes a cable sheath 1;
[0026] The cable sheath 1 has multiple insulation layers a2 inside, and an insulation layer b4 is located near the left side inside the cable sheath 1. Each of the insulation layers a2 and b4 contains a battery core a3 and a battery core b5, respectively. When the cable is connected to a power source, current flows from the power source into battery core a3 or battery core b5, and is then conducted to the load through these battery cores. Insulation layers a2 and b4 provide sufficient insulation protection to prevent current leakage, thereby ensuring the safe and orderly flow of current. The multi-layer insulation structure and the excellent properties of the irradiated rubber enable the cable to maintain stable operation in various harsh environments.
[0027] like Figure 2 and Figure 3 As shown, insulation layer a2 is made of irradiated rubber to increase its high temperature resistance, and multiple insulation layers a2 and b4 are made of cross-linked polyethylene to increase their tensile strength.
[0028] Insulation layer a2 is made of irradiated rubber material, primarily to enhance the cable's high-temperature resistance. This material can withstand high operating temperatures, allowing the cable to operate stably in high-temperature environments and ensuring the effectiveness of electrical insulation. Insulation layer b4 and multiple insulation layers a2 are all made of cross-linked polyethylene material. The cross-linked structure significantly improves the cable's tensile strength. Compared to ordinary polyethylene, cross-linked polyethylene has superior mechanical strength and toughness, effectively preventing breakage or insulation failure under tension or bending. The multiple battery cores a3 and b5 are arranged laterally, which helps optimize the use of internal space in the cable and improve current conduction efficiency.
[0029] like Figure 4 and Figure 5 As shown, the outer layer of the cable sheath 1 is provided with an outer jacket 8, and the inner wall of the outer jacket 8 is provided with a sliding inner liner 12 to reduce the friction between the outer jacket 8 and the cable sheath 1. The outer wall of the outer jacket 8 is provided with a sun protection layer 10, and the inside of the outer jacket 8 is provided with a reinforcing inner liner 11 to increase the hardness of the outer jacket 8. Both the front and rear ends of the outer wall of the outer jacket 8 are provided with sealing sleeves 9.
[0030] When the cable sheath 1 needs to be bent, the sealing sleeve 9 can be flipped outwards, and the outer sleeve 8 interacts with it on the surface of the cable sheath 1. Guided by the sliding inner liner 12, the outer sleeve 8 is guided to the bending area of the cable sheath 1. After it moves into place, the sealing sleeve 9 is flipped back, so that the sealing sleeve 9 contacts the cable sheath 1, increasing the friction between the outer sleeve 8 and the cable sheath 1. When the outer sleeve 8 is in use, the sun protection layer 10 effectively prevents ultraviolet radiation and extends the service life of the material. The reinforcing inner liner 11 improves the hardness and impact resistance of the outer sleeve 8, which enhances the structural integrity of the outer sleeve 8, making it less prone to deformation when subjected to external forces such as pressure or impact.
[0031] like Figure 3 As shown, multiple battery cells a3 and b5 are arranged horizontally, and each of the multiple battery cells a3 and b5 has a positioning rod 7 inside.
[0032] Each battery cell a3 and battery cell b5 is equipped with a positioning rod 7. The main function of the positioning rod 7 is to ensure the stable position of the battery cell inside the cable and prevent the battery cell from moving due to vibration or external force during manufacturing, installation and use, thereby affecting the performance and safety of the cable.
[0033] like Figure 2 As shown, reinforcing ribs 6 are provided inside the cable sheath 1 and near the left and right sides respectively.
[0034] The design of Reinforcing Rib 6 is intended to enhance the overall structural strength of the cable and improve its resistance to external impacts and pressures. By increasing the cable's resistance to pressure and impact, Reinforcing Rib 6 can better protect the internal battery core and insulation layer, preventing damage caused by external factors.
[0035] The implementation principle of this embodiment is as follows: When the cable is connected to a power source, current flows from the power source into battery cell a3 or battery cell b5, and is conducted to the load through these battery cells. Insulation layers a2 and b4 provide sufficient insulation protection to prevent current leakage, thereby ensuring the safe and orderly flow of current. The multi-layer insulation structure and the excellent properties of the irradiated rubber enable the cable to maintain stable operation in various harsh environments.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
