Description

A kind of communication cable for pipeline

Technical field

The utility model is related to technical field of electric wires and cables, more particularly to a kind of communication cable for pipeline.

Background technology

Because subsurface investigation operating environment is special thus extremely harsh for the technical requirements of communication cable for pipeline, pipe Road is also referred to as special cable with communication cable, is mainly manifested in the following aspects：First, communication cable is needed through usual For 90 ° longer of pipeline, and pipe diameter is slightly larger than the diameter of communication cable, thus it is excellent to require that communication cable has Intensity and resilience；Second, excellent high and low temperature resistance；Third, communication cable is used in deeper underground environment, and underground Environment is more moist, therefore it is required that it has extremely low water absorption rate, with avoid hydrone attack inside data wire pair, cause pair Communication efficiency produces influence；Fourth, requiring light self-weight and hardness height, but flexible effect is not lost, fifth, pipeline communication electricity Cable is once maintenance of breaking down is difficult, and the cost of overhaul is high, sixth, existing communication cable can be subjected to multiple torsion in erection process Turn, because communication cable is that the multi-turn layer material parcel cable core rounded or oval by section is made, communication cable exists When twisting, inside and outside circle integument integument is twisted, and degree is different to be turned.After communication cable is set up or for a period of time Afterwards, because the torsional-energy that torsion degree is different and puts aside can cause the joint of communication cable unstable, or even joint disconnects and come off, Make the Transmission of signal of communication.At present, how the quality of electric wire is being ensured, while in the limited diameter of section model of cable The interior more conductors of laying are enclosed, so that reducing underground cable sets up cost.

The content of the invention

For above-mentioned situation, increase conductor lays quantity while ensureing quality to realize, reaches reduction underground cable life Produce cost and set up the purpose of cost, the utility model aims to provide a kind of communication cable for pipeline, using following solution：

A kind of communication cable for pipeline, from inside to outside including be made up of a plurality of cable core units cable core, outside cable core The first lapping layer and restrictive coating outside the first lapping layer constitute, in addition to be filled in the first lapping layer and cable core unit it Between gap the first packed layer, it is characterised in that：Cable core unit is in regular hexagon, and it is wrapped that cable core unit includes the outermost 3rd Profile provided with composition star quad in layer and the second lapping layer being placed in the 3rd lapping layer, second lapping layer is in just Second is filled with space in four cores, two ground wires and a center reinforcemen for hexagon, second lapping layer Packed layer, the core include conductor and be coated on that conductor is outer and profile be in regular hexagon coating.

The cable core is constituted by seven in the cable core unit of cellular arrangement.

The core is in cellular arrangement.

The utility model, optimization core section and laying structure, increase core quantity, and the coating of regular hexagon is reduced Coating materials, while reducing space also saves the materials of packed layer, reduce set in cable core by glass fiber collection The center reinforcemen quantity that beam is constituted, due in the optimization of cable core cellular construction, while also ensure cable core from heavy and light, hardness it is high and Good resilience, the modularization of cable core unit lays the purpose for reaching and multiple cores being laid in equal sectional area, uses reduction Cables manufacturing cost and erection cost.

Embodiment

Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 to Figure 2, a kind of communication cable for pipeline, from inside to outside including being made up of a plurality of cable core units 11 Cable core 1, the first lapping layer 2 outside cable core and the restrictive coating 3 outside the first lapping layer 2 constitute, in addition to be filled in First packed layer 4 in gap between first lapping layer 2 and cable core unit 11, it is characterised in that：Cable core unit 11 is in regular hexagon, Cable core unit 11 includes outermost 3rd lapping layer 115 and the second lapping layer 114 being placed in the 3rd lapping layer, described second Profile provided with composition star quad in lapping layer 114 is in four cores 111 of regular hexagon, two ground wires 112 and one The second packed layer 116 is filled with space in center reinforcemen 113, second lapping layer 114, the core 111 includes Conductor 117 and be coated on that conductor 117 is outer and profile be in regular hexagon coating 118.

The cable core 1 is constituted by seven in the cable core unit 11 of cellular arrangement.

First lapping layer 2, the selection of material of the 3rd lapping layer 115 are polyester twining package tape.

The selection of material of restrictive coating 3 is modified thermoplastic elastomer.

First packed layer 4, the selection of material of the second packed layer 116 are petroleum jelly.

The ground wire 112, the selection of material of conductor 117 are single tin plating stranded copper wire.

The selection of material of center reinforcemen 113 is glass fiber set, and is surrounded with polyester twining package tape outside it.

The selection of material of second lapping layer 114 is aluminium foil.

The selection of material of conductor 117 is single tin plating stranded copper wire.

The selection of material of coating 118 is fluoroplastics.

The core 111 is in realize that tight is laid between cellular arrangement, each cable core unit 11, cable in same sectional area Core unit can lay that quantity is more, reduce the use of inserts, and the core 111 equally uses regular hexagonal section, and its structure is steady It is qualitative good, center reinforcemen quantity 113 can be reduced and realized without reducing the intensity of cable core unit 11 and rebound performance, each core 111 Tight is laid, and it is more that limited cross sections space can lay core 111.So in each cable core unit 11 of regular hexagon and each Core 111 is respectively face contact, it is to avoid occurs relative torsion as the rounded or oval cable internals of profile, protects Hinder the stable transmission of signal of communication, be conducive to the production and living of people.
