Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a natural radiation cross-linked cable. Background Art

[0002] Natural irradiation cable refers to a cable that has been cross-linked through natural radiation (such as solar radiation) in a natural environment. This cross-linking method is a relatively mild method and usually takes a long time to complete the cross-linking process. The cross-linking process of natural irradiation cable mainly promotes the change of the molecular structure in the cable insulation material through ultraviolet light and heat in natural radiation, thereby improving its performance. Natural irradiation cable has good heat resistance, aging resistance and chemical corrosion resistance, and is suitable for power transmission and communication systems in some special environments;

[0003] For example, a compression-resistant cable (publication number: CN220439272U) is disclosed. The various protective layers of this cable are easily punctured by sharp objects. If the location cannot be found and repaired in time, rainwater will enter the cable through the puncture hole on rainy days, causing damage to the cable. Therefore, technical personnel in this field have proposed a natural irradiation cross-linked cable. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a natural radiation cross-linked cable, which solves the problems in the above background.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a natural radiation cross-linked cable, comprising a conductor, the outer surface of the conductor is wrapped with an inner insulating sleeve, the outer surface of the inner insulating sleeve is wrapped with a flame retardant sleeve, the outer surface of the flame retardant sleeve is wrapped with a waterproof mechanism, the outer surface of the waterproof mechanism is wrapped with a protective mechanism, the waterproof mechanism comprises a waterproof sleeve, a plurality of evenly distributed first annular cavities are opened in the sleeve wall of the waterproof sleeve, and each of the first annular cavities is filled with polymer hydrogel powder.

[0006] As a further technical solution of the utility model, the flame retardant sleeve comprises a ceramic composite belt, the outer surface of the ceramic composite belt is wrapped with a low-smoke halogen-free polyurethane layer, and the surface of the low-smoke halogen-free polyurethane layer is wrapped with a low-smoke halogen-free polyolefin layer.

[0007] As a further technical solution of the utility model, the protection mechanism comprises a protection cover, and a surface of the protection cover is provided with a plurality of evenly distributed transparent bands.

[0008] As a further technical solution of the utility model, the filler is formed by uniformly mixing fluorescent powder and bittering agent powder.

[0009] As a further technical solution of the utility model, the protective cover is a natural radiation cover.

[0010] Beneficial Effects

[0011] The utility model provides a natural irradiation cross-linked cable. Compared with the prior art, it has the following beneficial effects:

[0012] 1. A naturally irradiated cross-linked cable. When a sharp object punctures the protective cover and the waterproof cover, rainwater will enter the first annular cavity in the waterproof cover through the puncture. When it contacts the polymer hydrogel powder in the first annular cavity, it will quickly solidify to form a gelatinous substance, thereby bonding with the inner surface of the waterproof cover, thereby blocking the puncture hole, automatically repairing the puncture hole, and playing a waterproof role. There is no need for staff to find the puncture hole and then repair it manually, reducing the workload of staff.

[0013] 2. A naturally irradiated cross-linked cable. The filler of this device is mixed with fluorescent powder and bitter agent. At night, the fluorescent powder can emit fluorescence through the protective cover to alert people to the location of the cable and prevent people from accidentally touching the cable. At the same time, if a mouse bites through the filler, it will taste the bitter agent in the filler, making the mouse feel uncomfortable and preventing it from continuing to gnaw the cable, thus playing the role of expelling the mouse.
