Abstract
The utility model relates to field of cables, particularly relates to a kind of power cable.This power cable, comprise copper conductor, cable core and crosslinked polyetylene insulated layer, described copper conductor is positioned at the inside of cable core, the outside of described copper conductor is provided with crosslinked polyetylene insulated layer, described crosslinked polyetylene insulated layer is wrapped in steel-tape armouring layer two, the outside of described cable core is provided with inner restrictive coating, and described inner restrictive coating is wrapped in steel-tape armouring layer one, and the outside of described steel-tape armouring layer one is provided with external sheath layer.A kind of power cable involved by the utility model, this power cable is provided with one deck steel-tape armouring layer respectively in the outside of conductor and cable core, so just greatly strengthen the intensity of cable self, even if outer field steel-tape armouring layer surprisingly ruptures, the steel-tape armouring layer of internal layer also can make conductor have certain intensity, thus ensures normal power supply.
Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of power cable.
Background technology
At present, along with the development of society, power consumption also increases thereupon, requires that the current capacity of cable is increasing, and the conductor wire core cross section of cable constantly increases, and the unit weight of cable increases thereupon day by day, so just requires that the tensile strength of cable is larger.In prior art, in order to increase the intensity of cable, usually set up steel-tape armouring layer in the outside of cable core, but the simple increase of one deck steel-tape armouring layer to cable strength is limited.
Therefore, in order to solve above technical problem, existing design is necessary to improve, devise a kind of power cable, this power cable is provided with one deck steel-tape armouring layer respectively in the outside of conductor and cable core, so just greatly strengthen the intensity of cable self, even if outer field steel-tape armouring layer surprisingly ruptures, the steel-tape armouring layer of internal layer also can make conductor have certain intensity, thus ensures normal power supply.
Utility model content
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: a kind of power cable, comprise copper conductor, cable core and crosslinked polyetylene insulated layer, described copper conductor is positioned at the inside of cable core, the outside of described copper conductor is provided with crosslinked polyetylene insulated layer, described crosslinked polyetylene insulated layer is wrapped in steel-tape armouring layer two, the outside of described cable core is provided with inner restrictive coating, described inner restrictive coating is wrapped in steel-tape armouring layer one, and the outside of described steel-tape armouring layer one is provided with external sheath layer.
A kind of power cable involved by the utility model, this power cable is provided with one deck steel-tape armouring layer respectively in the outside of conductor and cable core, so just greatly strengthen the intensity of cable self, even if outer field steel-tape armouring layer surprisingly ruptures, the steel-tape armouring layer of internal layer also can make conductor have certain intensity, thus ensures normal power supply.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of a kind of power cable of the utility model;
Wherein: 1, steel-tape armouring layer one; 2, external sheath layer; 3, cable core; 4, inner restrictive coating; 5, steel-tape armouring layer two; 6, crosslinked polyetylene insulated layer; 7, copper conductor.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.Accompanying drawing is the schematic diagram simplified, and only basic structure of the present utility model is described in a schematic way, therefore it only shows the formation relevant with the utility model.
Refer to Fig. 1, a kind of power cable, comprise copper conductor 7, cable core 3 and crosslinked polyetylene insulated layer 4, described copper conductor 7 is positioned at the inside of cable core 3, the outside of described copper conductor 7 is provided with crosslinked polyetylene insulated layer 6, and described crosslinked polyetylene insulated layer 6 is wrapped in steel-tape armouring layer 25, and the outside of described cable core 3 is provided with inner restrictive coating 4, described inner restrictive coating 4 is wrapped in steel-tape armouring layer 1, and the outside of described steel-tape armouring layer 1 is provided with external sheath layer 2.
A kind of power cable involved by the utility model, this power cable is provided with one deck steel-tape armouring layer respectively in the outside of conductor and cable core, so just greatly strengthen the intensity of cable self, even if outer field steel-tape armouring layer surprisingly ruptures, the steel-tape armouring layer of internal layer also can make conductor have certain intensity, thus ensures normal power supply.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range of the invention.
