Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as Fig. 7,8,9 and Figure 10 to Figure 15 shown in; the utility model environment-friendly type intelligent composite low-voltage cable; comprise the conductor 1 of wrapped composition successively from inside to outside, insulating barrier 2, packed layer 3, optical transmission unit 4, lapping layer 5 and oversheath 6; wherein; optical transmission unit 4 is hollow protective tube or microtubule fasolculus; microtubule fasolculus is made up of microtubule 9 and the microtubule fasolculus sheath 10 be coated on outside microtubule 9, and microtubule fasolculus has 2 or 3.According to use needs, microtubule fasolculus can be respectively the circular microtubule fasolculus of 2 cores, 4 cores circular microtubule fasolculus 12,2 core flat microtubule fasolculus 13,4 core of circular microtubule fasolculus 11,7 core square microtubule fasolculus 14 or 7 core polygon microtubule fasolculus 15.When optical transmission unit diameter and cable core diameter difference are apart from the optical transmission unit adopting the microtubule fasolculus of hollow protective tube or Figure 10 ~ Figure 15 structure to replace in Fig. 1, Fig. 2, Fig. 3 time larger; When optical transmission unit diameter and cable core diameter close to time, adopt the microtubule fasolculus (structure as Fig. 7, Fig. 8, Fig. 9) of 2 or many less core numbers to replace optical transmission unit as larger in diameter in Fig. 4, Fig. 5, Fig. 6.
For the optical fiber composite low-voltage cable of band sheathed structure, be also provided with inner covering 7 and zinc coat 8 in oversheath 6, zinc coat 8 is galvanized steel strip or zinc-coated wire.
The utility model microtubule fasolculus or hollow protective tube replace optical transmission unit; after cable line entirety has been laid; adopt the cable of microtubule fasolculus compound optical fiber to be blown into microtubule and form optical transmission unit; optical fiber is blown into microtubule and forms optical transmission unit; do not need reserved microtubule fasolculus; only need connect if any dividing a circuit also only to need with microtubule and a point connection by microtube joint with microtubule; core number is blown into optical fiber as required; every root microtubule can be blown at most 8 core fibre microtubule fasolculus; microtubule from 2 cores to 24 cores not etc., later as needed dilatation can be blown into optical fiber again.When as the cross-section of cable is less, fiber number is more, different cable gaps is pulled in the less microtubule fasolculus of available several core number into.Adopt the cable of hollow tube compound; after cable laying completes, optical cable is pulled in hollow protective tube and just can form optical transmission unit; as found in detection or use later, light unit damages maybe can not meet instructions for use, just the optical cable of optical cable extraction composite demand can be passed into again.
The utility model relates to a kind of environment-friendly type intelligent composite low-voltage cable; this cable can replace typical optical fiber composite low-voltage cable (OPLC); compare employing with optical fiber composite low-voltage cable (OPLC) and blow optical fiber microtubule fasolculus or hollow protective tube replaces optical transmission unit; as required optical fiber is blown into optical fiber microtubule after completing with the cable laying of optical fiber microtubule fasolculus compound, the blowing optical fiber microtubule and can connect with microtube joint of every root cable.Optical fiber can indefinite extension and do not need fiber alignment so in theory.As required optical cable (containing optical transmission cable in optical cable) is pulled in protection tube after completing with the cable laying of hollow protective tube compound.OPLC adopts optical transmission unit, connecting between every root cable must by fiber alignment, if a point circuit also will use optical cable distributing box, adopt the composite cable blowing optical fiber microtubule to divide circuit directly directly to be connected with joint and then to be blown into optical fiber according to circuit by the optical fiber microtubule that blows on two or more pieces cable, the large length of optical fiber can be ensured like this and without transition joint.Adopt hollow protective tube to be consider that optical transmission unit easily damages in cable production process, and can not repair, cause very large waste, poling can avoid this waste.
Optical fiber composite low-voltage cable (OPLC) is due to construction of cable reason own, optical transmission unit diameter is more much larger than microtubule fasolculus, when when the cross-section of cable is comparatively large, optical transmission unit diameter is less, optical transmission unit can directly be pulled in the gap of cable cabling core, the pulling force that optical transmission unit is subject to and pressure very little, when when the cross-section of cable is less, optical transmission unit diameter is larger, optical transmission unit must with cable core simultaneously stranding, the pressure that such optical transmission unit will bear very large pulling force and other cable core and gives, the probability that optical transmission unit damages is very large, in this case adopting hollow protective tube or blowing optical fiber microtubule fasolculus composite low-voltage cable adopts many small diameter microtubes bundles directly to pull in cable cabling different gap, can ensure that very little pulling force and pressure are born in microtubule fasolculus like this, optical fiber composite low-voltage cable (OPLC) is although also can do cable cost like this and will increase a lot, although adopt many microtubule fasolculus also to increase cost, but microtubule fasolculus is cheap, negligible compared with optical transmission unit.Adopt the cable of hollow tube compound; after cable laying completes, optical cable is pulled in hollow protective tube and just can form optical transmission unit; as found in detection or use later, light unit damages maybe can not meet instructions for use, just the optical cable of optical cable extraction composite demand can be passed into again.
When cable is produced, reserved part microtubule needs to be blown into optical fiber and extendible capacity during dilatation, simple and convenient, and optical fiber composite low-voltage cable must reserve the optical fiber in light unit, and cost is higher.Optical fiber microtubule fasolculus composite low-voltage cable feature is small investment, and flexibly, point circuit is simple and practical, can be blown into optical fiber as required in wiring, and optical fiber is whole non junction, it is little, easy to maintenance to decay, and can be blown into optical fiber maintenance again if any damage.
The utility model material therefor is all ep-type material, optical fiber or optical cable can play communication, signal transfer functions, optical fiber itself also has temp sensing function, cable is if any overload or local damage, cable temperature can raise, and if any temperature anomaly on the cable of whole length, reports to the police by optical fiber or optical cable, and the position probing of temperature anomaly is very accurate, so just can the operation conditions of Real-Time Monitoring cable.
