Accompanying drawing explanation
Fig. 1 is the structural representation of the power cable of a kind of anti-extrusion stretch-proof that the utility model proposes.
Embodiment
Below, by specific embodiment, the technical solution of the utility model is described in detail.
As shown in Figure 1, Fig. 1 is the structural representation of the power cable of a kind of anti-extrusion stretch-proof that the utility model proposes.
With reference to Fig. 1, the power cable of a kind of anti-extrusion stretch-proof that the utility model embodiment proposes, comprising: cable core 1, lapping layer 2, sheath 3, extrude layer 4 and outer jacket 5.
The core of leading of cable core 1 is made up of around the resistance to seal wire 12 of conductor 11 periphery interlacing that draws a Gen Naila conductor 11 and two rhizospheres, and when cable core 1 is subject to axial tension effect, the resistance to conductor 11 that draws is stressed in advance, avoids seal wire 12 to break, and ensures that the transmission of electric power is unobstructed.
The quantity of cable core 1 is set to three groups, and, on the arbitrary cross section of cable, the axial axis of three groups of cable cores 1 is equilateral triangle distribution and is provided with connector 6 between adjacent cable core 1, connector 6 adopts elastomeric material to be made, the both sides of connector 6 are connected on the periphery wall of adjacent two cable cores 1, cable core 1 and connector 6 cooperatively interact and crowd around, in formation buffering area, middle part 7, when depressed, by connector 6 and buffering area 7, and the coordinating of cable core 1 and lapping layer 2 gaps, stop mutually rolling between cable core 1 and cable core 1, rolling between avoiding because of cable core 1 causes cable core 1 inside conductor to be out of shape even disconnected core problem, ensure that the transmission of electric power is unobstructed.
Lapping layer 2 is coated on the periphery of the entirety that three groups of cable cores 1 are formed, sheath 3 is coated on the periphery of lapping layer 2, extrude the periphery that layer 4 is coated on sheath 3, outer jacket 5 is coated on the periphery extruding layer 4, wherein, sheath 3 and extruding to be provided with between layer 4 and resistance toly to draw layer 8, the periphery of sheath 3 is distributed with the standing groove 31 that some cross sectional shapes are arc, the resistance to main stay cord 81 drawing layer 8 to comprise some genesis analysis and the lateral connection rope 82 be arranged between adjacent two main stay cords 81, main stay cord 81 is arranged in standing groove 31, ensure that main stay cord 81 is at sheath 3 with extrude between layer 4 and be in vertical state, to improve the resistance to action effect drawing layer 8, strengthen the resistance to tensile strength of whole cable.
Resistance in the present embodiment draws the main stay cord 81 in layer 8 to adopt traction-resistant fibre to be made, the high-tensile that traction-resistant fibre has, high resiliency, persistence is high, flexibility good and the feature of lighter in weight, both the resistance to ability of drawing of cable had been enhanced, can not cause again the excessive increase of cable weight, and its elastomeric characteristic antagonism extrusion capability also plays certain booster action.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
