Abstract
The invention discloses an underground high-voltage electric power cable sheath pipe. The underground high-voltage electric power cable sheath pipe comprises a sheath pipe inner layer and a sheath pipe outer layer, wherein the sheath pipe outer layer is arranged outside the sheath pipe inner layer, the sheath pipe inner layer is a high-density PE particle material, the sheath pipe outer layer is a PP particle material, the sheath pipe inner layer and the sheath pipe outer layer are bonded by an adhesive, and the diameter of the cable sheath pipe comprising the sheath pipe inner layer and the sheath pipe outer layer is 80 millimeters to 300 nanometers. The underground high-voltage electric power cable sheath pipe is simple in structure and reasonable in design, is extruded and shaped by a plastic extruding machine in a high temperature, has the advantages of high strength, high toughness, high-temperature resistance, long service lifetime, no radiation pollution and the like, is difficult to break and age, and is mainly used for laying high-voltage electric power cables of 64KV/110KV and below 64KV/110KV.
Description
Technical field
The present invention relates to technical field of cable, specifically a kind of ground-buried high voltage power power cable protecting pipe.
Background technology
Protecting pipe is insulation protection heat-shrinkable T bush conventional on a kind of cable, and the main material of this series products is PE, hands over through irradiation
After joining and adding thermal enlargement the two processes, there is good thermal contraction function, can serve as in the pyrocondensation in cable accessory
Sheath and oversheath, and outer layer insulation water-proof jacket pipe etc..Ground-buried high voltage power power cable is mainly layed in groove
Portion.Owing to the plane of groove is not very neat, cable will be made to there will be the situation of bending after putting, time length is just held
Easily there is the situation of fracture, in groove, often have Mus ant simultaneously, cable may be gnawed by Mus ant cause impaired so that high
The service life of pressure power cable reduces.
Summary of the invention
It is an object of the invention to provide a kind of ground-buried high voltage power power cable protecting pipe, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, the present invention provides following technical scheme:
A kind of ground-buried high voltage power power cable protecting pipe, including protecting pipe internal layer and protecting pipe outer layer, outside described protecting pipe
Layer is positioned at protecting pipe internal layer, and protecting pipe internal layer is high density PE polyethylene particle material, and protecting pipe outer layer is PP polypropylene
Grain material；By binding agent adhesion between protecting pipe internal layer and protecting pipe outer layer；It is made up of protecting pipe internal layer and protecting pipe outer layer
Cable sheath tube a diameter of 80～300mm.
As the further scheme of the present invention: described protecting pipe internal layer and the common wall thickness of protecting pipe outer layer are 10～16mm；
Protecting pipe internal layer is identical with the length of protecting pipe outer layer, is 6～8m.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is simple, reasonable in design, through plastic extrusion
Machine high temperature extrusion and sizing, have intensity height, good toughness, high temperature resistant, easy fracture and aging, length in service life, nothing are not put
Penetrate the advantages such as pollution, be mainly used in the laying of 64KV/110KV and following high-tension electricity power cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1-protecting pipe internal layer, 2-protecting pipe outer layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly and completely
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments.Based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under not making creative work premise
Execute example, broadly fall into the scope of protection of the invention.
Referring to Fig. 1, a kind of ground-buried high voltage power power cable protecting pipe, including protecting pipe internal layer 1 and protecting pipe outer layer
2, described protecting pipe outer layer 2 is positioned at protecting pipe internal layer 1, and protecting pipe internal layer 1 is high density PE polyethylene particle material, protects
Set outer tube layer 2 is PP PP GRANULES material；By binding agent adhesion between protecting pipe internal layer 1 and protecting pipe outer layer 2,
Through plastic extruder high temperature extrusioning shaping；Cable sheath tube uses the high intensity thickeied to arrange, by protecting pipe internal layer 1 and sheath
A diameter of the 80～300mm of the cable sheath tube of outer tube layer 2 composition.
Further, protecting pipe internal layer 1 of the present invention and the common wall thickness of protecting pipe outer layer 2 are 10～16mm；Protect
Set inner tube layer 1 is identical with the length of protecting pipe outer layer 2, is 6～8m.
The present invention through plastic extruder high temperature extrusion and sizing, have intensity height, good toughness, high temperature resistant, not easy fracture and
Aging, length in service life, without features such as radiocontaminations, and without pouring concrete at the construction field (site) and ensure layer, construction is simple,
Expense is low, is substantially shorter the duration, is mainly used in 64KV/110KV and following high-tension electricity power cable underground laying
In.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and do not carrying on the back
In the case of the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter from
From the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
Although moreover, it will be appreciated that this specification is been described by according to embodiment, but the most each embodiment only comprises
One independent technical scheme, this narrating mode of description is only the most for clarity sake, and those skilled in the art should be by
Description is as an entirety, and the technical scheme in each embodiment can also be through appropriately combined, and forming those skilled in the art can
With other embodiments understood.
