Description
Technical field
The present invention relates to power cable field, specifically a kind of fluoroplastic insulated high-temperature-resistant power cable.
Background technology
Power cable is the cable for being used for transmission and distributing electric energy, and power cable is usually used in Urban Underground power grid, power station
Lead line, industrial and mining enterprises' in-line power and mistake river sea submarine transmission line.In power circuit, cable proportion just gradually increases
Add.Daily cable easily damages cable skin when being laid with, and triggers security risk, crisis worker's life and health, due to electric power electricity
Cable transmission electric power is strong, easily triggers fire dangerous situation, causes cable internal core to be damaged.
The content of the invention
In order to avoid proposing a kind of fluoroplastic insulated high-temperature-resistant power cable with solution above-mentioned technical problem, the present invention.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of fluoroplastic insulated high-temperature-resistant power cable, includes some segment conductor-cores of even distribution, some fan-shaped lines
At the center of core distribution, circular core is extruded between adjacent segment conductor-core, the segment conductor-core is outer with circular core
Portion is coated with liner layer, metal armouring, belting layer, oversheath successively from inside to outside, and the liner layer is internally provided with filler,
The filler is PP filler materials.
The segment conductor-core includes sector conductor, the No.1 insulating layer being coated on outside sector conductor, the circle core bag
No. two insulating layers for include round conductor, being coated on outside round conductor.
As a further improvement on the present invention, the sector conductor and round conductor are that copper wire is twisted.
As a further improvement on the present invention, the metal armouring is made of zinc-coated wire.
As a further improvement on the present invention, the No.1 insulating layer and No. two insulating layers are that crosslinked polyethylene is made.
As a further improvement on the present invention, the liner layer is made of ceramic fire prevention polyolefine material.
The beneficial effects of the invention are as follows：
Internal structure of the present invention is compact, and being installed between each core closely, can realize more core assembling and stability height,
Using metal armouring, effectively avoid cable skin from being damaged, reduce security risk, ensure personal safety, can thermal insulation fire insulation,
With good fire-proof high-temperature resistant performance, realize cable long working, substantially prolongs service life.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the present invention.
Embodiment
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1, a kind of fluoroplastic insulated high-temperature-resistant power cable, include some segment conductor-cores 1 of even distribution, if
At the center that dry root segment conductor-core 1 is distributed, circular core 2, the segment conductor-core 1 are extruded between adjacent segment conductor-core 1
Liner layer 3, metal armouring 4, belting layer 5, oversheath 6, the liner are coated with successively from inside to outside with the outside of circular core 2
Layer 3 is internally provided with filler 7, and the filler is PP filler materials.
Understood based on upper, this mounting structure, when can ensure that the core quantity of parcel inside cable is more, moreover it is possible to realize essence
The close and connection of high stability, optimizes cable performance.
The segment conductor-core 1 includes sector conductor 11, the No.1 insulating layer 12 being coated on outside sector conductor 11, the circle
Core 2 includes round conductor 21, No. two insulating layers 22 being coated on outside round conductor 21.
The sector conductor 11 and round conductor 21 are that copper wire is twisted.
The metal armouring 4 is made of zinc-coated wire.In this way so that cable is effectively anti-in transportational process
Only cuticular breakdown, protects internal core structure.
The No.1 insulating layer 12 and No. two insulating layers 22 are that crosslinked polyethylene is made.In this way, electricity can be made
Cable obtains good insulating properties.
The liner layer 3 is made of ceramic fire prevention polyolefine material.In this way, ceramic fire prevention polyolefin tool
There are good heat-insulated, fire protecting performance, enhance work capacity of the cable in high temperature limit environment, greatly improve cable performance.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improvement is both fallen within claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
