Abstract
The utility model discloses a buried type high voltage electric power cable protecting sleeve pipe made of a vinyl chloride. A protection layer is arranged between the inner wall and the outer wall of the protecting sleeve pipe. The protection layer comprises a flame retardation layer, a strengthening layer and a wearing layer; the strengthening layer is arranged between the wearing layer and the flame retardation layer, and the flame retardation layer and the wearing layer are bonded through an adhesive. Through the above mode, after being subjected to high temperature extruding and molding operation through a plastic extruding machine, the buried type high voltage electric power cable protecting sleeve pipe of the utility model is characterized by good flexibility, high temperature resistance, fracture resistance, ageing resistance, long service life, radiation-pollution-free property and the like. The buried type high voltage electric power cable protecting sleeve pipe is mainly applied to laying operation of electric cables of 64/110 kV and less.
Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of buried high voltage 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, passes through cross-linking radiation and adds these two techniques of thermal enlargement, has thermal contraction function.Can be used as pyrocondensation inner sheath, oversheath in electric cable accessories, and outer layer insulation water-proof jacket pipe.
Buried high voltage power cable is mainly laid in groove inside, and the plane of groove is not very neat, makes to put cable and have the situation of bending; long easily fracture of time; in groove, often have mouse ant, cable may be gnawed impaired simultaneously, and reduced the useful life of cable.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of buried high voltage power cable protecting pipe, extrude and shape through plastic extruder high temperature, have pliability good, high temperature resistant, not easy fracture and aging, long service life, without features such as radiocontaminations, it is mainly used in 64/110kV and with the cable laying of exerting oneself.
For solving the problems of the technologies described above; the technical scheme that the utility model adopts is: a kind of buried high voltage power cable protecting pipe is provided; the material of described protecting pipe is chlorinated vinyl chloride; between described protecting pipe inwall and protecting pipe outer wall, be provided with protective layer; described protective layer comprises flame-retardant layer, enhancement layer and wearing layer; the centre of described wearing layer and flame-retardant layer is enhancement layer, and described flame-retardant layer and wearing layer are by adhesive and enhancement layer adhesion.
In preferred embodiment of the utility model, the diameter of described protecting pipe is 90 ~ 250mm.
In preferred embodiment of the utility model, the pipe thickness of described protecting pipe is 5 ~ 10mm.
In preferred embodiment of the utility model, the length of described protecting pipe is 4 ~ 6m.
The beneficial effects of the utility model are: a kind of buried high voltage power cable protecting pipe of the utility model, extrude and shape through plastic extruder high temperature, have pliability good, high temperature resistant, not easy fracture and aging, long service life, without features such as radiocontaminations, it is mainly used in 64/110kV and with the cable laying of exerting oneself.
