Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
The structure of the utility model mixing cable as shown in Figure 1, include cable core, have successively outside the cable core cable core band,
Armor and oversheath, the cable core are made of several electric units and a light unit.Wherein：
Electric unit：Conductor is made using two class aluminum stranded conductors after pressing micro- drawing, insulation using polyvinyl chloride (PVC) or its
He extrudes insulating materials.
Conductor is formed using the annealing aluminium conductor drawing of two classes, and electrical contact is excellent.Round compacted comductor is pressed non-
On the basis of conductor, when twisted, press mold by the micro- drawing of conductor compacting by round pinch roller or circle, reduce stranded conductor list
Gap between line can reduce conductor diameter, drop while meeting the transmission capacity of the smaller D.C. resistance of electric unit, bigger
The dosage of the materials such as low cable insulation and sheath and the outer diameter for reducing finished cable.While increasing power supply cross-sectional area, protect
It is identical as 7/8 " optical cable size of standard to demonstrate,prove conductor assembly outer diameter.Aluminium core conductor compares the copper cable that equal transport requires, and cable production is applied
It is set as this and own wt to be greatly reduced, is conducive to the vertical run of cable and safe to use.
Light unit：Light unit is made of for hard low smoke and zero halogen sheath outside 2 optical fiber ribbon cable twisted synthesizing cables, optical fiber ribbon cable.
Optical fiber ribbon cable is outside square jacket by 8 core single mode optical fibers and band, optical fiber, and there is aramid fiber enhancing to fill out between optical fiber and optical fiber jacket
Core.
Optical cable use G.657A2 optical fiber be the insensitive optical fiber of bending loss, not only good bending property and also with it is G.652 general
Thang-kng fibre is compatible with, and can widen the range that optical cable uses；Optical cable reinforcer is done using aramid fiber, when both can guarantee fiber cable laying, having used
Tensile strength requirement, while flexibility when also meeting mixing cable laying is conducive to light when through the mechanical stresses such as by bending
The stabilization of fine performance；Optical fiber ribbon cable connects convenient for cluster (welding).Band inner fiber presses chromatography ordered arrangement, is conducive to maintenance and connects
When identify.Fibre ribbon is small, and the packaging density of optical fibre in optical cable can be improved, and can constitute more large core number according to use demand.
Optical cable unit is using hard LSZH as sheath, and shrinking percentage, good mechanical property, anti-side pressure are good, it can be ensured that optical fiber
Performance will not generate variation because being influenced when by external environment.
Cable core：It is that optical cable unit (i.e. light unit) is directly put that cable core, which uses 1+8 structures, centre, and peripheral 8 electric units are twisted into
Cable, the wrapped waterstop in gap.
The cable core of photoelectric mixed cable twists formula stranding using cage, is conducive to cable core structure and stablizes, meets performance requirement.Cable core outer room
The wrapped waterstop of gap (can be other bands), after advantage is stranding, cable core is not easy loosely, when connecting terminal, is easy to dismantle.
(as 7/8 " leakage cable, main purpose is easy for using structure size one embossing aluminium armouring of cable core external welding
7/8 " fixture originally), which has that shield effectiveness is excellent, anti-lightning strike, intensity is high, light-weight, tension, bending property and anti-
Side pressure performance is good, the advantages that.
Placed longitudinally two twisted aramid fiber tear ropes between cable core and embossing aluminum pipe, can longitudinally tear the armouring of mixing cable
And restrictive coating, the convenient unlatching to photoelectric mixed cable outer jacket when in use.
Oversheath：(other materials can be also extruded using squeezing tubular type and vacuumize mode and extrude a strata alkene outside cable core band
Sheath) sheath, sheath material not only have it is low temperature resistant, and burn when without toxic gas generate, be conducive to environmental protection；Vacuumize mode
So that sheath is close with cable core structure, the structural stability of mixing cable is improved, when mixing cable by larger pulling force, cable core knot
Structure can still keep stable, be conducive to cable lifting.
Above-described embodiment does not limit the utility model in any way, every by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the scope of protection of the utility model.
