Abstract
The utility model is related to power cable technical field; specifically related to a kind of basalt fibre buried cable; the cable includes the core that conductor outer wrapping basalt fiber cloth is constituted; and it is wrapped in the refractory insulating layer outside core; and the silicon rubber protective layer extruded outside core and refractory insulating layer, and silicon rubber protective layer outer wrapping restrictive coating；At least one layer of basalt fibre braiding layer is surrounded with outside the refractory insulating layer；Fiber packed layer is provided between the core and refractory insulating layer.Relative to prior art, the utility model uses basalt fibre, and hygroscopicity is low, acid-alkali-corrosive-resisting, adiabatic and excellent insulating property, will not vary with temperature and expand with heat and contract with cold, steady quality, the underground environment for the humidity that is particularly suitable for use in, extends the service life of cable, reduces frequency of maintenance.
Description
Technical field
The utility model is related to power cable technical field, and in particular to a kind of basalt fibre buried cable.
Background technology
In order to the attractive in appearance of urban environment and go sightseeing ground view it is more charming, cable grounding engineering become it is more and more important,
Lower wiring is also of increasing concern.
High technical fibre is the important foundation material of National defense industry construction and support high-tech industry development, its direct relation
To the construction and the upgrading of pillar industry in national economy of defense-related science, technology and industry.Basalt fibre is exactly after carbon fiber, aramid fiber, superelevation
The fourth-largest high technical fibre after relative molecular mass polyethylene fibre.It is that have very in defence and military field 21 century
A kind of high technical fibre of important application, is a kind of new material for embodying science and techniques of defence strategic.Basalt fibre has excellent
Good mechanical property, heat endurance, chemical stability and electrical insulation capability.There is staple fibre excellent heat resistance, heat to shake surely
Qualitative, chemical stability and excellent heat insulation sound absorbent performance, therefore have broad application prospects.
Maintenance difficult after buried cable breaks down, use environment is severe, therefore normal cable corrosion-resistant, it is impossible to full
The demand of sufficient provided underground environment.
Utility model content
To solve the above problems, the utility model provides a kind of basalt fibre buried cable.
The technical solution of the utility model is：
A kind of basalt fibre buried cable includes the core that conductor outer wrapping basalt fiber cloth is constituted, and is wrapped in
The silicon rubber protective layer extruded outside refractory insulating layer outside core, and core and refractory insulating layer, and silicon rubber protective layer
The restrictive coating of outer wrapping；At least one layer of basalt fibre braiding layer is surrounded with outside the refractory insulating layer；The core and resistance to
Fiber packed layer is provided between fiery insulating barrier.
The basalt fiber cloth is formed with basalt fibre twisting weaving yarns.
The core is single core or three cores or many stranded cores that are arranged in isosceles triangle.
The conductor uses copper wire or aluminium alloy.
The fiber packed layer use basalt fibre, glass fibre, rock wool, asbestos, chemical fibre in one kind or
It is several.
The restrictive coating is made of transparent barrier material.
Reflecting strips and isolychn are provided with the restrictive coating.
Relative to prior art, the utility model beneficial effect is：
The utility model uses basalt fibre, and hygroscopicity is low, acid-alkali-corrosive-resisting, adiabatic and excellent insulating property, will not
Vary with temperature and expand with heat and contract with cold, steady quality, the underground environment for the humidity that is particularly suitable for use in extends the service life of cable,
Reduce frequency of maintenance.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of basalt fibre buried cable includes the line that conductor outer wrapping basalt fiber cloth is constituted
The silicon rubber protective layer extruded outside core 4, and the refractory insulating layer 3 being wrapped in outside core 4, and core and refractory insulating layer 3
2, and the outer wrapping of silicon rubber protective layer 2 restrictive coating 1；At least one layer of basalt is surrounded with outside the refractory insulating layer 3 fine
Tie up braiding layer；Fiber packed layer 5 is provided between the core 4 and refractory insulating layer 3.
The basalt fiber cloth is formed with basalt fibre twisting weaving yarns.The core 4 be single core or
Three cores or many stranded cores arranged in isosceles triangle.The conductor uses copper wire or aluminium alloy.The fiber is filled out
Layer 5 is filled using the one or several kinds in basalt fibre, glass fibre, rock wool, asbestos, chemical fibre.The restrictive coating 1 is adopted
It is made of transparent barrier material.Reflecting strips and isolychn are provided with the restrictive coating 1.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
Protection domain of the present utility model.
