Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a photoelectric composite high-voltage fireproof cable. Background Art

[0002] Optoelectronic composite high-voltage fireproof cables are suitable for use as transmission lines in broadband access network systems. They are a new access method that integrates optical fiber and copper transmission wire to solve broadband access, equipment power consumption, and signal transmission problems. Existing optoelectronic composite high-voltage fireproof cables are usually equipped with a protective layer on the outside. When used outdoors in rainy and snowy winter weather, the protective layer will freeze on the surface, which can easily break the optoelectronic composite high-voltage fireproof cable. It is also easy to break when bent during long-term use and is not convenient for cooling.

[0003] Chinese patent publication number CN210039751U discloses an optoelectronic composite high-voltage fireproof cable, comprising a connecting layer and a sheath. The connecting layer is provided with an outer protective layer on one side, wherein a composite tape is provided on one side of the outer protective layer, a yarn is provided on one side of the composite tape, a waterproof grease is provided on one side of the yarn, an optical fiber layer is provided inside the waterproof grease, and the sheath adjacent to the optical fiber layer is provided inside the waterproof grease, and copper wire is provided inside the sheath. The optoelectronic composite high-voltage fireproof cable has a connecting layer made of thermoplastic resin. The outer surface of the connecting layer is coated with an anti-ice and snow coating. The anti-ice and snow coating can be applied using various coating methods and can self-cure at room temperature to form a dry coating film on the protected surface. When the cable is used in winter, ice and snow falling on the surface of the connecting layer can be caused to slide off by the anti-ice and snow coating, thereby preventing ice and snow from adhering. The coating also has multiple functions such as corrosion resistance, wear resistance, anti-aging resistance, and surface self-cleaning, ensuring that the cable surface does not freeze during winter use.

[0004] Although the above-mentioned patented optoelectronic composite fireproof cable is coated with an anti-ice and snow coating on the outside of the cable, this coating solidifies at room temperature. However, when the coating is exposed to the external environment for a long time, the solid coating is likely to fragment, and these fragments may fall from high altitudes. Fragments falling from high altitudes may cause safety hazards. Utility Model Content

The protective tube is also coated with a layer of anti-ice and snow coating. The prismatic square holes opened on the protective tube not only divide the entire anti-ice and snow coating into smaller areas to prevent the larger anti-ice and snow coating from breaking and falling off, but also solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photoelectric composite high-voltage fireproof cable, comprising a protective tube, a prismatic square hole is opened on the protective tube, a protective layer is provided on one side of the protective tube, and also comprises an anti-ice and snow coating, the anti-ice and snow coating is provided on the protective layer and the outer surface of the protective tube, the protective layer is provided with a composite tape on the side away from the inner wall of the protective tube, a binding yarn is provided on the inner side of the composite tape, a wrapping tube is provided on the inner side of the binding yarn, and waterproof grease is filled between the wrapping tube and the binding yarn.

This coating cures at room temperature, but when the coating is exposed to the external environment for a long time, the solid coating is likely to fragment, and these fragments may fall. Fragments falling from high altitudes may cause safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
