Along with national grid and south electric network strengthen the construction to intelligent grid, in addition to backbone network builds high pressure, supertension large capacity transmission circuit energetically, power optical fiber is tried hard to recommend to family at user side, what optical cable used is all nonmetallic materials, therefore optical fiber low-voltage cable light unit during manufacturing and using easily is damaged by external forces, cause the optical fiber low-voltage cable cannot be properly functioning, even scrap.
Summary of the invention
The technical problem to be solved there is provided a kind of high strength optical fiber composite cable, improves cable safety during normal use and extends the service life of cable, and being substantially reduced power system operation cost.
A kind of high strength optical fiber composite cable of the present invention, the center of described cable is provided with the reinforcing obturator being made up of glass fiber, reinforce obturator and be provided with three the first circular holes, it is provided with insulating optical fiber compound wire core in each first circular hole, it is externally provided with the flame retardant coating that thickness is 2-3mm reinforcing obturator, flame retardant coating is externally provided with the metal armor layers that thickness is 2-3mm, and metal armor layers is externally provided with the stress control tube that thickness is 4-6mm, extrudes the aluminium sheath that thickness is 2-3mm outside stress control tube；Described stress control tube is provided with second circular hole, is provided with as standby fiber unit in the second circular hole.
Improving further, described insulating optical fiber compound wire core is formed by fiber unit is stranded with the insulated wire cores being arranged on outside fiber unit.
Improving further, described fiber unit is made up of optical fiber and the steel Loose tube that is located at outside fiber unit.
Improving further, insulating barrier that described insulated wire cores by conductor, is extruded in outside conductor and the insulation screen being extruded in outside insulating barrier are constituted.
Improving further, the internal diameter size of the first described circular hole is identical with the external diameter size of insulation screen.
Improving further, the internal diameter size of the second described circular hole is identical with the external diameter size of steel Loose tube.
The beneficial effects of the present invention is:
1, the present invention is coated with layer of metal conductive monofilament at armor of cable outer cladding after optical fiber cladding steel Loose tube, makes light unit obtain three-layer metal protection, thus solves optical fiber easily by problem that external force is impaired；All it is coated with a light unit in each conductor, it is ensured that the uniform force of every light unit, thus reaches the stability of structure；The combination of light unit and power wire core is prone to residential quarter electric energy and signal equipment lays simultaneously, reduces construction workload, decreases the construction period, has saved construction costs, reduces cost.
2, the present invention is provided with stress control tube, it is that a kind of specific insulation is moderate, the heat-shrinkable tube of the special electrical parameter that dielectric constant is bigger, electric parameter is utilized to force the stress evacuating of insulation shield incision position to become along the more uniform distribution of stress tube, process electric stress concentration problem in cable, and control to alleviate electric field stress and concentrate, light, install easily, performance good.
3, the present invention is provided with a standby fiber unit in stress control tube so that during a certain optical fiber cisco unity malfunction in cable core, can substitute for its work, facilitates the normal use of cable.
4, the present invention is provided with reinforcing obturator, and is fixed insulating optical fiber compound wire core by circular hole so that be not susceptible to displacement, and also plays the effect of filling, and glass fiber will not burn, and will not produce harmful substance.
5, cable jacket is that metallic aluminium is made, and will not burn, even if also will not produce any harmful gas under flame condition, and ensure that other layers in cable are not burned.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, one high strength optical fiber composite cable of the present invention, the center of described cable is provided with the reinforcing obturator 1 being made up of glass fiber, reinforce obturator and be provided with three the first circular holes, being provided with insulating optical fiber compound wire core in each first circular hole, described insulating optical fiber compound wire core is formed by fiber unit is stranded with the insulated wire cores being arranged on outside fiber unit；Wherein, fiber unit is made up of optical fiber 2 and the steel Loose tube 3 that is located at outside fiber unit；Insulating barrier 5 that described insulated wire cores by conductor 4, is extruded in outside conductor and the insulation screen 6 being extruded in outside insulating barrier are constituted.
