Description
Technical Field
The utility model relates to a wire and cable specifically is a fluorine plastic cable that waterproof performance is good, belongs to the power cable field.
Background
Wire products used to transmit electrical energy, information and to effect electromagnetic energy conversion are known as wire cables. The fluoroplastic cable is specially used for electric wires and cables with fluoroplastic as a sheath. The fluoroplastic has fluorine atoms in the molecular structure, so that the fluoroplastic has many excellent properties such as excellent electrical properties, high temperature resistance, aging resistance, chemical medium resistance and the like.
Although the fluoroplastic cable has a plurality of excellent performances, the fluoroplastic cable has no special advantages in the aspect of water resistance, the existing fluoroplastic cable also has a water-proof design and has a certain water-proof effect, but the existing water-proof design only adopts conventional means such as a water-proof sheath or a filled water-proof yarn and a water-proof belt, the water inlet and damage duration of the cable can be properly prolonged, the water cannot be completely eradicated, once the water inlet phenomenon occurs, the cable can develop irreversibly until the power transmission change is caused by the water inlet of the cable, and the improvement is necessary.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve lies in: the fluoroplastic cable with good waterproof performance is provided, and the problem that the fluoroplastic cable cannot be reversed once a water inflow phenomenon occurs in the prior art is solved.
In order to solve the technical problem, the utility model provides a technical scheme is: the utility model provides a fluorine plastic cable that waterproof performance is good, includes sinle silk, insulating layer, filler, around band, fluorine plastic sheath, its characterized in that: the waterproof layer is arranged between the fluoroplastic sheath and the HDPE protective layer, the heat tracing band is provided with a plurality of heat tracing bands, the heat tracing bands are arranged inside the waterproof layer, and the waterproof layer is made of water absorption materials capable of being repeatedly used.
Preferably, the water-blocking layer is made of water-absorbing silica gel.
Preferably, the heat tracing band is uniformly arranged inside the waterproof layer and at a position close to one side of the fluoroplastic sheath.
Preferably, the wrapping tape is made of a waterproof film.
The beneficial effect that above-mentioned technical scheme obtained is: when the water phenomenon appears in the fluoroplastic cable, moisture is absorbed by the water-absorbing material of the water-blocking layer firstly, the fluoroplastic cable is prevented from entering the fluoroplastic cable, the heat tracing band is electrified to generate heat, the generated heat promotes the water absorbed by the water-absorbing material in the water-blocking layer to evaporate, the water-absorbing material recovers the water-absorbing performance again, the water-absorbing layer recovers the original state, the HDPE protective layer has the function of forming outer layer protection, the phenomenon that a large amount of moisture directly enters the water-blocking layer to cause the absorption capacity exceeding the water-absorbing material in a short time is avoided, the last waterproof layer is provided for coating the wire core in the wrapping band by adopting a waterproof film, the waterproof performance of the fluoroplastic cable is further improved, and.
Drawings
Fig. 1 is a schematic structural diagram of one embodiment of the present invention.
Labeled as: 1. the cable comprises a cable core, 2, an insulating layer, 3, a filler, 4, a wrapping tape, 5, a fluoroplastic sheath, 6, a water-resistant layer, 7, a heat tracing tape, 8 and an HDPE protective layer.
Detailed Description
The technical solutions of the present invention will be described in detail with reference to the accompanying drawings, and in the following description, many specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention should not be limited by the specific embodiments disclosed below.
As shown in fig. 1, which is a schematic structural diagram of one embodiment of the present invention, a fluoroplastic cable includes a wire core 1, an insulating layer 2, a filler 3, a wrapping tape 4, a fluoroplastic sheath 5, a water-blocking layer 6, a heat tracing tape 7 and an HDPE sheath 8, the water-blocking layer 6 is disposed between the fluoroplastic sheath 5 and the HDPE sheath 8, the heat tracing tape 7 is disposed inside the water-blocking layer 6, the water-blocking layer 6 in this embodiment is made of water-absorbing silica gel, but it should be noted that the water-blocking layer may also be made of recycled water-absorbing material, the heat tracing tape 7 in this embodiment is uniformly disposed inside the water-blocking layer 6 and is close to one side of the fluoroplastic sheath 5, so that the water is disposed to be emitted in a direction away from the interior of the fluoroplastic cable, but may also be disposed at any position inside the water-blocking layer 6, and only the use effects are different and have no substantial difference, the wrapping tape 4 in this embodiment adopts a waterproof film, and other common materials can be adopted, and only the waterproof performance is inferior to that of the waterproof film.
The beneficial effect that above-mentioned technical scheme obtained is: when the water phenomenon appears in the fluoroplastic cable, moisture is absorbed by the water-absorbing material of the water-blocking layer 6 firstly, the fluoroplastic cable is prevented from entering the fluoroplastic cable, the heat tracing band 7 is electrified to generate heat, the generated heat promotes the water absorbed by the water-absorbing material in the water-blocking layer 6 to evaporate, so that the water-absorbing material recovers the water-absorbing performance again, the water-absorbing layer recovers the original state, the HDPE protective layer 8 is used for forming outer layer protection, the phenomenon that a large amount of moisture directly enters the water-blocking layer 6 to cause the absorption capacity exceeding the water-absorbing material in a short time is avoided, the wrapping band 4 is provided with a last waterproof layer for wrapping the wire core 1 in the wrapping band, the waterproof performance of the fluoroplastic cable is further improved, and.
The above description is only for the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also covered by the protection scope of the present invention, which is defined by the following claims.
