Abstract
The utility model relates to a cable, more specifically say and relate to adopt gradient combined material's withstand voltage cable of insulating type that it is insulating to possess the two -stage, and the electric wire thermal diffusivity is good, possesses compressive structures in order to form the protection to the electric wire. Supporting the shell and being located insulating I inside of overlapping, stopping I is filled and is located insulation cover I and supports between the shell in I inside just stopping I in the insulating cover. Insulating cover II links to each other with the electric wire and insulating cover II wraps up in the skin of electric wire, and insulating cover II is located and supports inside the shell. Stopping II is filled in supporting the shell and stopping II is located insulating cover II and supports between the shell.
Description
Technical field
This utility model relates generally to a kind of cable, more specifically to the resistance to voltage cable of insulated type using gradient composites.
Background technology
Cable is high voltage power transmission and the requisite power equipment of long distance powedr transmission.Can run into various construction environment in electric power process of deployment, some construction environments are not suitable for making somebody a mere figurehead cable, now cable can only be imbedded underground.Cable embedment underground needs by sealing and protection, and cable itself also should possess the performance of certain protecting against shock pressure to avoid the damage of cable core.
Utility model content
This utility model, mainly solving the technical problems that provide the resistance to voltage cable of insulated type using gradient composites, possesses two class B insulations, and electric wire thermal diffusivity is good, possesses compression-resistant structure so that electric wire is formed protection.
For solving above-mentioned technical problem; this utility model relates to a kind of cable; more specifically to the resistance to voltage cable of insulated type using gradient composites; including insulation sleeve I, inserts I, support shell, inserts II, insulation sleeve II and electric wire; possess two class B insulations; and electric wire thermal diffusivity is good, possesses compression-resistant structure so that electric wire is formed protection.
Supporting shell and be positioned at insulation sleeve I inside, inserts I is filled in insulation sleeve I inside and inserts I and at insulation sleeve I and supports between shell.Insulation sleeve II is connected with electric wire and insulation sleeve II is wrapped in the outer layer of electric wire, and insulation sleeve II is positioned at inside support shell.Inserts II is filled in supporting shell and inserts II at insulation sleeve II and supports between shell.
As the further optimization of this programme, this utility model uses the support shell cross section described in the resistance to voltage cable of insulated type of gradient composites to be hexagon.
As the further optimization of this programme, this utility model uses the inserts I described in the resistance to voltage cable of insulated type of gradient composites and the material of inserts II to be all crystal magnesium oxide powder.
This utility model uses the resistance to voltage cable of insulated type of gradient composites to provide the benefit that: possess two class B insulations, and electric wire thermal diffusivity is good, possesses compression-resistant structure so that electric wire is formed protection.
Accompanying drawing explanation
The resistance to voltage cable of insulated type of gradient composites is used to be described in further detail this utility model with specific implementation method below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation that this utility model uses the resistance to voltage cable of insulated type of gradient composites.
In figure: insulation sleeve I 1；Inserts I 2；Support shell 3；Inserts II 4；Insulation sleeve II 5；Electric wire 6.
Detailed description of the invention
Detailed description of the invention one: present embodiment is described below in conjunction with Fig. 1; this utility model relates to a kind of cable; more specifically to the resistance to voltage cable of insulated type using gradient composites; including insulation sleeve I 1, inserts I 2, support shell 3, inserts II 4, insulation sleeve II 5 and electric wire 6; possess two class B insulations; and electric wire thermal diffusivity is good, possesses compression-resistant structure so that electric wire is formed protection.
Supporting shell 3 and be positioned at insulation sleeve I 1 inside, inserts I 2 is filled in insulation sleeve I 1 inside and inserts I 2 and at insulation sleeve I 1 and supports between shell 3.Support shell 3 and carry out the pressure power of unloading for pressure to external world.Inserts I 2 is used for filling space.
Insulation sleeve II 5 is connected with electric wire 6 and insulation sleeve II 5 is wrapped in the outer layer of electric wire 6, and it is internal that insulation sleeve II 5 is positioned at support shell 3.Electric wire 6 is restrainted into a branch of and is dielectrically separated from electric wire 6 formation by insulation sleeve II 5.
Inserts II 4 is filled in supporting shell 3 and inserts II 4 at insulation sleeve II 5 and supports between shell 3.Insulation sleeve I 1 and insulation sleeve II 5 all use gradient composites, the good insulation preformance of gradient composites.
Detailed description of the invention two:
Below in conjunction with Fig. 1, present embodiment being described, embodiment one is described further by present embodiment, and described support shell 3 cross section is hexagon.Hexagon supports shell 3 and relies on each limit stress to unload power.
Detailed description of the invention three:
Below in conjunction with Fig. 1, present embodiment being described, embodiment one is described further by present embodiment, and described inserts I 2 and the material of inserts II 4 are all crystal magnesium oxide powder.Inserts I 2 and the inserts II 4 of this kind of material not only possess good insulating properties but also possess good heat conductivity.
Described above is not limitation of the utility model; this utility model is also not limited to the example above; change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, fall within protection domain of the present utility model.
