Description
Technical field
The utility model is related to a kind of cables, more particularly to a kind of hollow power cable.
Background technology
Power cable is the cable for being used for transmission and distributing electric energy, and power cable draws for Urban Underground power grid, power station
Go out circuit, industrial and mining enterprises' in-line power, but that there is pull resistances is poor for existing power cable, flexing resistance is poor, unsafe problem.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of hollow power cable, can improve pull resistance and
Bending strength, it is safer.
The utility model is to solve above-mentioned technical problem by following technical proposals：Hollow power cable includes protection
Layer, the first filled layer, the first belting layer, the second filled layer, cable body, the first filled layer are located in protective layer, the first band
Layer is located in the first filled layer, and the second filled layer is located in the first belting layer, and cable body is located in the second filled layer, cable sheet
Body includes protective case, the second belting layer, shielded layer, copper bar, conductor shield, conductor, and protective case is located in the second filled layer, the
Two belting layers are located in protective case, and shielded layer is connected with copper bar, and conductor shield is located in shielded layer, and conductor is located at conductor shielding
In layer.
Preferably, hollow layer is equipped in second filled layer.
Preferably, the hollow layer periphery is equipped with restrictive coating.
Preferably, the hollow power cable uses flat row structure.
The positive effect of the utility model is：The utility model can improve pull resistance and bending strength, and pacify
Entirely.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
As shown in Figure 1, the hollow power cable of the utility model include protective layer 1, the first filled layer 2, the first belting layer 3,
Second filled layer 4, cable body 5, the first filled layer 2 are located in protective layer 1, and the first belting layer 3 is located in the first filled layer 2,
Second filled layer 4 is located in the first belting layer 3, and cable body 5 is located in the second filled layer 4, and cable body 5 includes protective case
11, the second belting layer 12, shielded layer 14, copper bar 13, conductor shield 15, conductor 16, protective case 11 are located at the second filled layer 4
Interior, the second belting layer 12 is located in protective case 11, and shielded layer 14 is connected with copper bar 13, and conductor shield 15 is located at shielded layer 14
Interior, conductor 16 is located in conductor shield 15.
It is equipped with hollow layer 44 in second filled layer 4, to improve tensile strength.
44 periphery of hollow layer is equipped with restrictive coating 42, hollow layer is protected, to improve safety.
Hollow power cable uses flat row structure, improves bending strength in this way, and when use more stablizes.
The operation principle of the use of the new type is as follows：When cable integrally improves bending strength use in this way using flat row structure
More stablize, protective layer, protective case, restrictive coating are made of phenolic aldehyde FPR for protecting cable that can promote safety in this way, and first fills out
Layer, the second filled layer are filled for filled cable, and the first belting layer, the second belting layer are used for fire-retardant, shielded layer, copper bar, conductor screen
Distribution of the layer for improving electric field is covered, conductor is used to improve the high-tensile of cable entirety for conduction, hollow layer.
In conclusion the utility model can improve pull resistance and bending strength, and safety.
Particular embodiments described above, the technical issues of to the solution of the utility model, technical solution and advantageous effect
It has been further described, it should be understood that the foregoing is merely specific embodiment of the utility model, not
For limiting the utility model, within the spirit and principle of the utility model, any modification for being made, changes equivalent replacement
Into etc., it should be included within the scope of protection of this utility model.
