Description

A kind of water repellent electric cable
Technical field
The utility model relates to field of cables, in particular to a kind of water repellent electric cable.
Background technique
In the prior art, cable is usually the cable of similar rope as several or made of several groups of wire strandings, and every group is led Mutually insulated between line, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation, and multi rack is located at sky In or be mounted in underground, the bottom, be used for transmission, distribute electric energy or transmit electric signal.Cable in outdoor or underground use process, when When Exterior cable is damaged, outside moisture can penetrate into the cable core of cable from cable bad part, damage to cable, thus shadow It rings the service life of cable and there are some potential safety problemss.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of water repellent electric cables, solve cable existing in the prior art Cable core water inlet after influence cable service life, there are problems that security risk.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions:
The outer layer of a kind of water repellent electric cable, including cable core, the cable core is successively coated with shielded layer and waterproof layer, Filled layer is provided between the shielded layer and waterproof layer, the outer surface of the waterproof layer is wound with supporting part, the supporting part Outer layer matcoveredn is set, it is described filled with water-proofing powder in the gap that the waterproof layer, protective layer and supporting part three are formed The height of projection of supporting part is 1-3mm.
Preferably, the outer surface of protective layer described above is provided with a raised line, the two sides of the raised line are symmetrically arranged with At least one inclined diversion groove.
Preferably, the height of projection of raised line described above is 2-5mm, the depth of the diversion groove is 1-3mm.
Preferably, waterproof layer described above is polyvinyl chloride waterproofing membrane.
Preferably, supporting part described above is inhibiting tape.
Preferably, protective layer described above is rubber sleeve.
The beneficial effects of the utility model are: the water repellent electric cable of the utility model, structure is simple, by waterproof layer and guarantor Supporting part is added between sheath, improves the compression strength of cable, meanwhile, it is formed in waterproof layer, protective layer and supporting part three Gap in fill water-proofing powder, when outside moisture enters, water-proofing powder can water-swellable, block gap, prevent the further of water Infiltration, to guarantee the use validity and safety of cable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural schematic diagram in the utility model between waterproof layer, protective layer and supporting part.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other It can be combined with each other.
As shown in Figs. 1-2, a kind of water repellent electric cable, including cable core 1, the outer layer of cable core 1 are successively coated with shielding Layer 2 and waterproof layer 3, are provided with filled layer 4 between shielded layer 2 and waterproof layer 3, the outer surface of waterproof layer 3 is wound with supporting part 5, Matcoveredn 6 is arranged in the outer layer of supporting part 5, is filled with and blocks water in the gap that waterproof layer 3, protective layer 6 and 5 three of supporting part are formed Powder 7, the height of projection of supporting part 5 are 1-3mm.In use, according to use environment, can flexible design supporting part 5 height of projection And the winding density of supporting part 5, such as outdoor or underground using when may be designed as 3mm, when indoor use, may be designed as 1mm. The water repellent electric cable of the utility model, structure is simple, by adding supporting part 5 between waterproof layer 3 and protective layer 6, improves electricity The compression strength of cable, meanwhile, water-proofing powder 7 is filled in the gap that waterproof layer 3, protective layer 7 and 6 three of supporting part are formed, when outer When boundary's moisture enters, the meeting water-swellable of water-proofing powder 7 blocks gap, prevents the further infiltration of water, to guarantee the use of cable Validity and safety.
The outer surface of protective layer 6 is provided with a raised line 61, and the two sides of raised line 61 are symmetrically arranged at least one and inclined draw Water groove 62.Above-mentioned design can make water flow flow away along diversion groove 62, reduce residence time of the water flow on cable, reduce The probability of moisture infiltration cable.
The height of projection of raised line 61 is 2-5mm, and the depth of diversion groove 62 is 1-3mm.The design of above-mentioned size, uses effect Fruit is more preferably.
Waterproof layer 3 is polyvinyl chloride waterproofing membrane.Polyvinyl chloride waterproofing membrane has tensile strength height, elasticity and elongation percentage Greatly, water-resistance and the features such as good against weather, effectively can prevent moisture from entering cable conductor.
Supporting part 5 is inhibiting tape.It selects inhibiting tape (fire-resistant isinglass belt can be used), cable is made to have flame retardant property, improve The safety in utilization of cable.
Protective layer 6 is rubber sleeve.Rubber sleeve is selected, because it has elasticity, can be generated when cable is hit in the external world certain Cushion effect can effectively protect cable and is not destroyed.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
