State light unit stranded, in multiple described cores and described smooth unit are all coated on by described outer casing, described outer casing by
Interior to being followed successively by outward polyester belt lapping layer, inner liner, mica tape flame retardant coating, zinc-plated copper strips armor and external sheath layer, many institutes
State the gap location between core and described smooth unit and be provided with packed layer, between described external sheath layer and described zinc-plated copper strips armor
It is provided with tear rope.
Preferably, the quantity of described tear rope is two, and two described tears are restricted along the length direction setting of described cable
And running through whole described cable, two described tear ropes are symmetricly set in the both sides of described cable.
Preferably, described insulating barrier is made up of weatherability polyvinyl chloride or weatherability crosslinked polyethylene.
Preferably, described external sheath layer is made up of LSOH anti-flaming polyethylene or flame-proof polyvinyl chloride.
Preferably, described packed layer is PP rope or asbestos cord.
Compared with prior art, the beneficial effects of the utility model are: the simple in construction of this optical fiber composite low-voltage cable, energy
Enough transmission electric power and fiber optic communication simultaneously, the problem solving secondary wiring, reduce the workload of construction, also save construction
Cost, by arranging flame retardant coating and armor in cable, strengthens machinery and the fire resistance of cable, makes the application model of cable
Enclose wider, and the setting of packed layer, enhance the block-water effect of cable, and make the structure more rounding of cable；It addition, at this light
Being provided with tear rope between external sheath layer and the armor of fine composite low-voltage cable, the convenient stripping to cable, to improve construction
Efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, external sheath layer, 2, mica tape flame retardant coating, 3, inner liner, 4, polyester belt lapping layer, 5, light unit, 6, tear
Split rope, 7, insulating barrier, 8, core, 9, zinc-plated copper strips armor, 10, packed layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: optical fiber composite low-voltage cable, including many cores 8,
Light unit 5 and outer casing, in the present embodiment, the quantity of core 8 is preferably four, and the quantity of light unit 5 is one, four lines
Core 8 is stranded with light unit 5, so by the combination of core 8 with light unit 5, makes electric power and transmits with the realization that communicates simultaneously, solve
The problem of secondary wiring, thus saved cost and improve work efficiency, it is exhausted be extruded in outside conductor that core 8 includes conductor
Edge layer 7, multiple cores 8 and light unit 5 be all outsourced in covering layer is coated on, and it is wrapped that outer casing is followed successively by polyester belt from the inside to the outside
Layer 4, inner liner 3, mica tape flame retardant coating 2 and zinc-plated copper strips armor 9, extrude external sheath layer 1 outside zinc-plated copper strips armor 9,
External sheath layer 1 is made up of LSOH anti-flaming polyethylene or flame-proof polyvinyl chloride；Many cores 8 and the outside of light unit 5 and position
Being space in the inside of lapping layer, this gap is provided with packed layer 10, and wherein, packed layer 10 can be PP rope or asbestos cord,
This optical fiber composite low-voltage cable is made to possess good block-water performance.
Being provided with tear rope 6 between external sheath layer 1 and zinc-plated copper strips armor 9, specifically, the quantity of tear rope 6 is two,
Two tear ropes 6 arrange and run through whole cable along the length direction of optical fiber composite low-voltage cable, and two tears are restricted and 6 are respectively symmetrically
