Technical Field
[0001] The utility model belongs to the technical field of halogen-free cross-linked wires, and particularly relates to an anti-corrosion halogen-free cross-linked wire. Background Art
[0002] Halogen-free cross-linked power cables refer to cables manufactured without adding halogen-containing flame retardants, thereby reducing the release of harmful substances during the use of the cables and greatly reducing environmental pollution. Since halogen-free cross-linked wires use halogen-free materials, although they have environmental protection characteristics such as flame retardancy and low smoke, in an environment containing acids, alkalis, etc., the halogen-free materials may undergo chemical reactions. During the use of existing halogen-free cross-linked wires, a large amount of heat is generated. In this environment, the halogen-free cross-linked wires react rapidly with corrosive gases or liquids in the external environment, resulting in corrosion and damage to the insulating layer of the halogen-free cross-linked wires. As the insulating layer is damaged, its insulating performance may decline, affecting the safety performance and service efficiency of the cables. Summary of the Utility Model

A plurality of grooves are formed on the outer wall of the heat dissipation component for placing cable cores. A waterproof layer is sleeved outside the heat dissipation component. An anti-aging layer is sleeved outside the waterproof layer. The heat dissipation component partially penetrates through the waterproof layer and abuts against the inner wall of the anti-aging layer. A fabric layer is sleeved outside the anti-aging layer.
[0005] Preferably, it further includes an insulating layer sleeved on the outer wall of the cable core. The insulating layer is located in the groove, and there is a gap between the insulating layer and the inner wall of the groove. An accommodation cavity is formed between the insulating layer and the inner wall of the groove and the waterproof layer. The accommodation cavity is filled with silicone rubber to form a filling layer.
[0006] Preferably, the heat dissipation component includes an annular column. A plurality of protrusions are circumferentially arrayed on the outer wall of the annular column to form a plurality of grooves. The outer wall of the protrusion away from the annular column is connected with a plurality of sector-shaped convex blocks having the same number as the protrusions. A plurality of heat dissipation strips are installed on the outer wall of each sector-shaped convex block, and the heat dissipation strips are circumferentially arrayed on the outer wall of the sector-shaped convex block.

[0010] Preferably, the insulating layer is made of cross-linked polyethylene material, and the anti-aging layer is made of polyphenylene sulfide material.
[0011] Preferably, the fabric layer is made by weaving aluminum foil.
[0012] Beneficial effects: The present utility model relates to a halogen-free cross-linked anti-corrosion wire. By isolating a heat dissipation component outside the cable core, the heat dissipation component can dissipate the heat generated when the cable core is in use. With the cooperation of the heat dissipation columns, the annular columns, the convex sector-shaped bumps and the heat dissipation strips, the heat dissipation efficiency is improved, thereby preventing the halogen-free cross-linked wire from being corroded when in a high-temperature environment.

A plurality of grooves 200 are formed on the outer wall of the heat dissipation component 100 for placing the cable core 300. The cable core 300 is wrapped with an insulating layer 700. The insulating layer 700 is made of cross-linked polyethylene material and is located in the groove 200. There is a gap between the insulating layer 700 and the inner wall of the groove 200. An accommodation cavity is formed between the insulating layer 700 and the inner wall of the groove 200 and the waterproof layer 400. The accommodation cavity is filled with silicone rubber to form a filling layer 800. The heat dissipation component 100 is sleeved with a waterproof layer 400 on the outside. The waterproof layer 400 is made of a composite of polyethylene and an aluminum layer. The outer wall of the waterproof layer 400 is sleeved with an anti-aging layer 500. The anti-aging layer 500 is made of polyphenylene sulfide material. The heat dissipation component 100 partially penetrates through the waterproof layer 400 and abuts against the inner wall of the anti-aging layer 500. The outer wall of the anti-aging layer 500 is sleeved with a fabric layer 600. The fabric layer 600 is made of aluminum foil weaving. A filling layer 800 is arranged between the heat dissipation component 100 and the cable core 300. While ensuring heat dissipation, the filling layer 800 will not have a negative impact on the overall electrical performance of the cable.
[0019] In a further embodiment, as Figure 3 shown, the heat dissipation component 100 includes an annular column 101. A heat dissipation column 105 is installed inside the annular column 101. The heat dissipation column 105 is made of a metal material. A plurality of protrusions 102 are circumferentially arrayed on the outer wall of the annular column 101 to form a plurality of grooves 200.

The annular column 101, the protrusions 102, the sector-shaped convex blocks 103 and the heat dissipation strips 104 are all made of aluminum hydroxide material. By isolating the heat dissipation component 100 outside the cable core 300, the heat generated when the cable core 300 is used can be dissipated by the heat dissipation component 100.
