The task of
the utility model 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 one of the utility model concrete embodiment, described first lapping layer is the polyester twining package tape.
in another concrete embodiment of the utility model, described restrictive coating is the thermoplastic elastomer (TPE) of modification.
in another concrete embodiment of the utility model, 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 utility model, 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 the utility model, and described data wire is to being stranded each other, and the right quantity of data wire is that 4-6 is right.
the utility model more and among concrete embodiment, described second lapping layer is an aluminium foil.
the utility model so that concrete embodiment in, the thickness of described aluminium foil is 0.035-0.045 ㎜.
the utility model again more and among concrete embodiment, described the 3rd lapping layer is the polyester twining package tape.
at again and then among concrete embodiment of the utility model, the thickness of described polyester twining package tape is 0.020-0.030 ㎜.
The technical scheme that
the utility model provides; 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.
