Low existing insufficient and defect, provides a kind of roll-forming conductor structure suitable for the production of aerial insulated cable conductor, with
It solves the above problems.
Technical problem solved by the invention can be realized using following technical scheme:
A kind of aerial insulated cable roll-forming conductor structure, including radial section be circular inner conductor and according to
It is the multilayer outer conductor outside circular round inner conductor, the radial section of every layer of outer conductor that secondary multilayer, which is stranded in the radial section,
For annular shape, and every layer of outer conductor can make up the outer layer uniconductor that radial section is circular ring shape and constituted by multiple, and outer layer list is led
The radial section of body is sector;Wherein the inner circle of innermost layer outer conductor is contacted with the outer circle fitting of the round inner conductor, outer layer
The inner circle of outer conductor be bonded with the outer circle of the outer conductor of internal layer.
In a preferred embodiment of the invention, connecing between outer layer uniconductor adjacent in the outer conductor of the outer layer
The seam stitched between the outer layer uniconductor adjacent with the outer conductor of internal layer circumferentially mutually staggers.
In a preferred embodiment of the invention, the radial section is circular round inner conductor from a root diameter to cutting
Face is that circular single round inner conductor is constituted.
In a preferred embodiment of the invention, the radial section be circular round inner conductor by least two with
One radial direction of upper composition is that the radial section of circle is that fan-shaped interior uniconductor is twisted.
In a preferred embodiment of the invention, connecing between outer layer uniconductor adjacent in the outer conductor of the outer layer
The seam between adjacent interior uniconductor in seam and inner conductor mutually staggers.
In a preferred embodiment of the invention, the radial section is circular single round inner conductor, radial section
The circle single line that diameter is Φ 2.91mm is all made of for fan-shaped interior uniconductor, outer layer uniconductor to pass through after active device for rolling and molding
It rolls.
The present invention is using roll-forming technology will then by the hole type design of different size by drawing circle single line
Circle single line is rolled into the sector conductor of design requirement after through active device for rolling and molding, by gathering mold forming, reaches work
Skill sets the round conductor of each specification sectional area requirement, meets aluminium, copper conductor uses.
The present invention is according to the difference of specification, and the number of plies of conductor is different with every layer of radical, to guarantee the circle after conductor strand
The angle of whole degree requirement, two straight flanges of each single sector conductor design of specifications design is different, by making after twisted molding
Cable conductor becomes rounding.
Production efficiency of the present invention is 3~5 times of typical round compact conductor production efficiency.Traditional round compact conductor one
As fill factor can only achieve 88% or so.The present invention can greatly improve conductor filled coefficient, reach 94% or more, conductive surface
Rounding effectively reduces conductor diameter in the case where meeting cable conductor and complying with the national standard requirements, and reduces insulation dosage, from
And achieve the purpose that save social resources.
Due to using technical solution as above, internal structure of the present invention is compact, and fill factor reaches 0.9 or more, highest
Up to 0.94;And than typical round to press structural cable conductor diameter small by 3% or more by the present invention of same specification, is meeting country's mark
While the requirement of standard, the utilization rate of raw material can be effectively provided, reduces the waste to social resources.
