Description
Technical field
the invention belongs to technical field of electric wires and cables, are specifically related to a kind of pipeline and use telecommunication cable.
Background technology
pipeline is referred to as special cable by people usually with telecommunication cable; And why be called as special cable; Be because because the subsurface investigation operating environment is special; Thereby very harsh for the specification requirement of this kind cable, be embodied in the following aspects that is not limited to: one of which, because telecommunication cable need pass 90 ° the pipeline that is uneven in length that is generally tens of rice and even up to a hundred meters; And pipe diameter is slightly larger than the diameter of telecommunication cable, thereby requires telecommunication cable to have excellent intensity and resilience; Its two, need guarantee desirable high and low temperature resistance; Its three because telecommunication cable uses at darker underground environment, and underground environment is comparatively moist, therefore requires it to have extremely low water absorption rate, to avoid the inner data wire of hydrone invasion and attack right, causes communication efficiency is exerted an influence; Its four, require light self-weight and hardness high, but do not lose flexible effect, or the like.At present, no matter be the design department or the production firm of electric wire, all make pipeline satisfy these four requirements at least and effort as far as possible with telecommunication cable.
the applicant has done literature search; Chinese patent Granted publication CN201345252Y recommends to have " two insulation air pipes are used telecommunication cable "; This patent scheme is to the right cored wire conductor of the line that constitutes each grid line be covered successively outward PE insulating barrier and fluoroplastic insulation layer, is then covered by sheath and protects.The capable described strong point of its Instructions Page 3 2-4 can be embodied, promptly the fire retardant insulating performance can be embodied comparatively ideally.
Invention Announce CN10207743A provide " telecommunication cable with fabric lining "; This patent is avoided the friction between the adjacent cable through the fabric lining is set outside cable; So that easy mounting, thereby four technical problems aforesaid people not being devoted to solve provide the corresponding techniques enlightenment.And; Application for a patent for invention publication No. CN101789285A introduces has " the shielded communication cable that is used for subway "; But the reference on this patent application scheme does not possess skills with cable for pipeline communication that is to say can't therefrom obtain to remedying the enlightenment of above-mentioned four technical problems.Also; Utility model patent Granted publication CN201522888U discloses has " flame-retardant communication cable is used in the colliery "; Its structure is: coated insulation inner sheath, APL aluminum plastic laminate layer, wire armoring layer and oversheath successively outside cable core; Wherein: oversheath is a halogen-free anti-flaming polyolefin, and the insulation cable core comprises some to twisted-pair feeder, outside twisted-pair feeder, coat polyester band, copper wire woven shield and outside the polyester band.The deadweight of telecommunication cable that this patent scheme provides is heavier, and is whole stiff, is difficult to bending, gives to install and promptly lays and use brings inconvenience, and especially can't adapt to the piping erection of wide-angle.
can't solve four technical problems that aforesaid industry is devoted to solve all sidedly because the disclosed technology contents of patent documentation of giving an example above being not limited to all exists; For this reason; The applicant has done long-term and good try; And under confidential state, prove practicable through the experiment of being done, the technical scheme that will introduce below is based on producing under this prerequisite.
Summary of the invention
task of the present invention is to provide a kind of to be had excellent intensity and resilience and uses and adapt to wide-angle and install and lay; Have desirable high and low temperature resistance and use the good environmental suitability of embodiment; Have being able to of standing out from one's fellows stop steam invasion and attack data wire to and use the extremely low water absorption rate of embodiment and under long-term wet environment, use and have from heavy and light to ensure; Hardness is high but do not lose soft bending effect and use the pipeline that ensures the convenience of installing and using and use telecommunication cable.
task of the present invention is accomplished like this; A kind of pipeline is used telecommunication cable; Comprise cable core, be positioned at the first outer lapping layer of cable core and be positioned at the outer restrictive coating of lapping layer, cable core comprises that the plurality of data line is right, and each data wire is to being made up of the pair of conductors coating outer with being coated on each conductor; Be characterised in that: described cable core also comprises second, third lapping layer, central reinforce member and ground wire; Second lapping layer is wrapped external at described data wire, and the 3rd lapping layer is wrapped outside second lapping layer, and the quantity of ground wire equates with the right quantity of data wire; And it is right to follow respectively in each data wire; Central reinforce member is positioned at the center of cable core, and central reinforce member is made up of the glass fiber boundling and is coated by the polyester twining package tape, and described plurality of data line is to centering on central reinforce member and stranded with central reinforce member.
in a concrete embodiment of the present invention, described first lapping layer is the polyester twining package tape.
in another concrete embodiment of the present invention, described restrictive coating is the thermoplastic elastomer (TPE) of modification.
in another concrete embodiment of the present invention, described conductor is that the zinc-plated stranded copper wire of 0.10-0.50 ㎜ constitutes by filament diameter; Described coating is the fluoroplastics coating.
in another concrete embodiment of the present invention, described ground wire is that the zinc-plated stranded copper wire of 0.10-0.20 ㎜ constitutes by filament diameter.
also have among the concrete embodiment of the present invention, and described data wire is to being stranded each other, and the right quantity of data wire is that 4-6 is right.
are more of the present invention and among concrete embodiment, described second lapping layer is an aluminium foil.
in of the present invention and then concrete embodiment, the thickness of described aluminium foil is 0.035-0.045 ㎜.
of the present invention again more and among concrete embodiment, described the 3rd lapping layer is the polyester twining package tape.
in again of the present invention and then concrete embodiment, the thickness of described polyester twining package tape is 0.020-0.030 ㎜.
technical scheme provided by the invention; Owing in cable core, be provided with the central reinforce member that constitutes by the glass fiber boundling; Therefore make cable core excellent, can satisfy requirement is laid in the wide-angle installation of pipeline from heavy and light, hardness height and resilience; Because coating has the high and low temperature resistance (60～200 ℃) of standing out from one's fellows, therefore can embody adaptability well to environment for use; Because restrictive coating has excellent heatproof effect (60～125 ℃), and has good weatherability and hydrolytic resistance, fearless in the wet environment use, thereby can prevent that outside steam intrusion data wire is right, guarantee communication efficiency.
