In view of this, the utility model is intended to propose a kind of physical foam insulation answering machine data transmission cable, significantly can improve the transmission frequency of cable, increases transmit port quantity, has simplified shielding layer structure under the prerequisite ensureing shielding properties simultaneously.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of physical foam insulation answering machine data transmission cable, comprises by two or the stranded cable core of four insulated single wires, and insulating liner, basic sheath, inner sheath, double-tape armor layer, oversheath that cable core outside sets gradually from the inside to the outside; Earial drainage copper conductor is provided with between described insulating liner and basic sheath; Described insulated single wire is made up of the skin foam skin physical blowing polyolefin insulation structure of copper conductor and copper conductor outside.
Further, described basic sheath can be aluminium sheath.
Further, described aluminium sheath is indulged bag and is welded on insulating liner outside, forms all-sealed structure.
Further, described basic sheath can also be the composite sheath comprising vertical bag embossing one side plastic-aluminum belt.
Further, described basic sheath is close to by described earial drainage copper conductor.
Further, described insulating liner is wrapped non-hygroscopic polyethylene jacket or extrudes polyethylene jacket.
Further, described inner sheath is pe sheath or LSOH anti-flaming sheath.
Further, described oversheath is pe sheath or LSOH anti-flaming sheath.
Further, described copper conductor and earial drainage copper conductor are TR type annealed copper wire.
Relative to prior art, the utility model has following advantage:
1) insulation of this cable have employed " skin-bubble-Pi " physical blowing polyolefin insulation, there are good moisture-proof function and excellent insulation property, and the relative dielectric constant of dielectric is significantly reduced, reduce the transmission attenuation of cable, effectively can improve the transmission performance of cable.
2) basic sheath adopts the aluminium sheath type cable of aluminium sheath, aluminium sheath type cable more of the prior art eliminates one deck inner sheath outside vertical bag embossing one side aluminum plastic belt and one side aluminum plastic belt, like this, just can by suitably increasing the aluminum layer thickness of aluminium sheath, reach identical shielding properties effect, can effectively reduce manufacturing process's process, improve production efficiency.Meanwhile, significantly can also reduce the external diameter of finished cable, not only the aluminum layer thickness therefore suitably increasing aluminium sheath can not increase manufacturing cost, significantly can reduce manufacturing cost on the contrary.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1-polyolefin insulation structure, 2-copper conductor, 3-insulating liner, 4-earial drainage copper conductor, 5-basis sheath, 6-inner sheath, 7-double-tape armor layer, 8-oversheath.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of physical foam insulation answering machine data transmission cable, as shown in Figure 1, comprise by two or the stranded cable core of four insulated single wires, and insulating liner 3, basic sheath 5, inner sheath 6, double-tape armor layer 7, oversheath 8 that cable core outside sets gradually from the inside to the outside; Earial drainage copper conductor 4 is provided with between described insulating liner 3 and basic sheath 5; Described insulated single wire is made up of the skin-bubble-Pi three-layer co-extrusion physic foaming polyolefin insulation structure 1 of copper conductor 2 and copper conductor 2 outside.
It should be noted that, skin-bubble-Pi three-layer co-extrusion physic foaming polyolefin insulation structure 1 makes the relative dielectric constant of the dielectric of cable reduce about 40%, significantly can promote the transmission performance of cable, this insulation system has excellent moisture-proof function and insulation property.
Described basic sheath 5 can aluminium sheath, and this aluminium sheath indulges bag, and to be welded on insulating liner 3 outside, forms all-sealed structure.Owing to eliminating one deck inner sheath outside vertical bag embossing one side aluminum plastic belt and one side aluminum plastic belt in aluminium sheath type structure, therefore, aluminum layer thickness can carry out suitable increase on the basis of original technology, and such more compact structure has saved space under the prerequisite guaranteeing shielding properties.
Wherein, described basic sheath 5 is close to by described earial drainage copper conductor 4.Cable internal structure consolidation, good stability, can not twist during retractable cable easily.
Described basic sheath 5 can also be composite sheath, and this composite sheath comprises vertical bag embossing one side plastic-aluminum belt.Now, the aluminium face of vertical bag embossing one side plastic-aluminum belt is close to by earial drainage copper conductor.
Wherein, described insulating liner 3 is wrapped non-hygroscopic polyethylene jacket or extrudes polyethylene jacket.
As required, described inner sheath 6 can adopt pe sheath or LSOH anti-flaming sheath.Described oversheath 8 can adopt pe sheath or LSOH anti-flaming sheath.
Wherein, described copper conductor 2 and earial drainage copper conductor 4 are TR type annealed copper wire, ensure the softness of cable, are convenient to folding and unfolding, not easy fracture.
It should be noted that, in actual production, can also centered by cable core, uniformly arrange four groups, often organize two earial drainage copper conductors, such structural design, is not only conducive to the rounding property of the entirety of cable, also assures that higher fail safe, even if cable side is subject to foreign object impact, this side earial drainage copper conductor damages, and does not also affect the use of cable, fail safe is high, and result of use is good.
In addition, can also arrange central reinforce member in the center of cable core, as cotton and hemp rope, under the prerequisite increasing cable weight not significantly, construction of cable intensity be strengthened, stability is better, durable in use.
The insulation of this cable have employed " skin-bubble-Pi " physical blowing polyolefin insulation, there are good moisture-proof function and excellent insulation property, and the relative dielectric constant of dielectric is significantly reduced, reduce the transmission attenuation of cable, effectively can improve the transmission performance of cable.
During the sheath employing aluminium sheath of basis, aluminium sheath type cable more of the prior art eliminates one deck inner sheath outside vertical bag embossing one side aluminum plastic belt and one side aluminum plastic belt, can effectively reduce manufacturing process's process, improve production efficiency.Meanwhile, the external diameter of finished cable can also significantly be reduced.
Therefore, adopting aluminium sheath at basic sheath 5, when producing aluminium sheath type cable, as required, by suitably increasing the aluminum layer thickness of aluminium sheath, shielding properties can be improved, to meet product requirement.Because aluminium sheath type cable more of the prior art eliminates one deck inner sheath outside vertical bag embossing one side aluminum plastic belt and one side aluminum plastic belt, therefore, not only the aluminum layer thickness suitably increasing aluminium sheath can not increase manufacturing cost, significantly can reduce manufacturing cost on the contrary.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
