Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Shown in referring to Fig.1, an embodiment of the dual-layer Parallel reinforcer optical cable of the utility model, including cable core, be coated on
Sheath 2 and outer jacket 3 outside cable core, the sheath 2 and outer jacket 3 are formed by protective cover material extrusion molding, are set in the cable core
It is equipped with light passing unit 1；Be embedded with two groups of non-metal reinforcement members 4 in the sheath 2, the non-metal reinforcement member 4 with it is described interior
The protective cover material co-extrusion of sheath 2 and go out, non-metal reinforcement member 4 described in two groups is separately positioned on the two sides of the sheath 2, every group
The non-metal reinforcement member 4 includes two FRP bars disposed in parallel；The FRP bar uses diameter for the thin FRP bar of 1mm, compares
In the FRP bar of common 1.8mm, the FRP bar that diameter is 1.0mm is arranged in sheath 2 makes the jacket thickness of entire sheath 2
It reduces, saves protective cover material dosage；Be embedded with two groups of metal reinforcements 5 in the outer jacket 3, the metal reinforcement 5 with it is described
The protective cover material co-extrusion of outer jacket 3 and go out, metal reinforcement 5 described in two groups is separately positioned on 4 outside of the non-metal reinforcement member,
Metal reinforcement 5 described in every group includes two and steel wire is arranged in parallel, and the steel wire uses the finer wire of 1.0mm, compared to common
1.45mm steel wire, in outer jacket 3 be arranged diameter be 1.0mm steel wire reduces the jacket thickness of entire outer jacket 3, section
Protective cover material dosage is saved, and cable diameter is further decreased by the jacket thickness of sheath 2 and outer jacket 3；Be arranged two groups it is nonmetallic
