Abstract
A kind of round conductor is filled with sheath multi-core power cable without cable core, the cable includes exterior sheath and the internal process core of at least three, the cross section of the process core is in the petal shape that multiple circles surround, more arc sections that the shape of cross section of the sheath is formed after being made up for the petal shape outer edge of core connect shape, without filler material between process core outside inside sheath.The cable of this patent is because without cable core filling and band, the shortcomings that can avoiding above-mentioned this filled-type cable, and because reducing the cost of cable without filling and band material.
Description
Technical field
The technical field of the auxiliary tool of fruit detection chemical examination is the utility model is related to, more particularly to a kind of round conductor
No cable core is filled with sheath multi-core power cable.
Background technology
During common round conductor multi-core power cable stranding, need densely to insert non-hygroscopic in cable core gap and fill out
Fill material and cable core is tightened with suitable belt and makes cable core that finally oversheath is extruded on cable core into actual circle.
Common round conductor multi-core power cable cable core because internal voids it is larger, in order to make cable in actual circle
Shape, has inserted the packing material of high thermal resistance in cable core gap, makes cable in closely knit tight structure and into the circle of consolidation
Structure, this structure can influence distributing for the heat that cable conductor produces under a load, especially operate at full capacity production in cable
During raw heat, the current-carrying capacity of cable is limited to a certain extent, and because the heat that conductor produces is collected inside cable core not
It is easy to lose, so as to cause the aging of cable conductor insulation and reduce the service life of cable.
Utility model content
To solve the above problems, the utility model proposes a kind of round conductor without cable core filled with sheath multicore electric power electricity
Cable.
The technical solution of the utility model is:A kind of round conductor is filled with sheath multi-core power cable without cable core, it is special
Sign is that the cable includes exterior sheath and the internal process core of at least three, and the cross section of the process core is in
The petal shape that multiple circles surround, the shape of cross section of the sheath are formed after being made up for the petal shape outer edge of core
More arc sections connection shape, without filler material between process core outside inside sheath.
Preferably, the sheath is overcoat polymer.
Preferably, described every process core includes at least core sheath and internal multifibres process conductor.
The technique effect of the utility model
The cable of this patent is because without cable core filling and band, the shortcomings that can avoiding above-mentioned this filled-type cable, and
Cost because reducing cable without filling and band material.
Sheath outside this patent cable conductor plays the role of protecting conductor insulation.
This patent cable cover(ing) is directly extruded in round insulation core surface after stranding, and cable profile is in similar to cable core
Non-circular appearance.
This patent is suitable for the medium-pressure power cable and lv power cable of round conductor multicore.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram that round conductor is filled with sheath multi-core power cable without cable core
1. cable cover(ing)s, the sheath of 21. process cores, the conductor of 22. process cores in figure.
Embodiment
Embodiment one:Referring to Fig. 1, a kind of round conductor is filled with sheath multi-core power cable, its feature without cable core in figure
It is that the cable includes exterior sheath and the internal process core of at least three, and the cross section of the process core is in more
The petal shape that a circle surrounds, what the shape of cross section of the sheath was formed after being made up for the petal shape outer edge of core
More arc sections connect shape, without filler material between process core outside inside sheath.The sheath is overcoat polymer.Institute
The every process core stated includes at least core sheath and internal multifibres process conductor.
Round conductor is a kind of multicore cable for having sheath filled with sheath multi-core power cable without cable core, it is characterised in that
Cable conductor do not place packing material in gap outwardly and inwardly, also no cable core tightens band, and by polymer oversheath
A kind of non-circular cable being directly extruded on cable core.It is primarily adapted for use in by the multicore that round insulation core is formed without armouring electric power
Cable.
