Abstract
The utility model relates to an all-dielectric central beam tube optical cable. The optical cable comprises optical fibers. Fiber paste is filled in the gap among the optical fibers. The optical fibers and the fiber paste are disposed in a PBT tube. A sheath is disposed on the outer side of the PBT tube. Four to eight FRP reinforcing elements are disposed in the sheath and uniformly distributed on the circumference in the sheath. The diameter of the FRP reinforcing element is from 1 mm to 1.5 mm. The all-dielectric central-beam tube optical cable has characteristics of light weight, little diameter, flexibleness, and preventing induced voltage and is especially suitable for being laid in indoor and outdoor crowded pipelines, pipelines with little bending radius, or being laid with a strong-current line. Compared with a conventional central beam tube optical cable with same number of cores, the all-dielectric central beam tube optical cable has 40% lighter weight and 20% shorter diameter.
Description
Technical field
The utility model relates to a kind of optical cable, especially relate to a kind of for the indoor or outdoors pipeline crowded with small-bend radius or with the optical cable of electric wiring with route.
Background technology
The reinforcement of existing central-beam tube type fiber optic cable all adopts the symmetrical cloth of two steel wires to be placed on both sides in restrictive coating.And steel wire is harder, and weight is large, and high resilience is not flexible.Steel wire pushes the PBT sleeve pipe injury optical fiber of the inside due to elastic force when preventing that optical cable is crooked, existing central-beam tube type fiber optic cable also vertically is surrounded by one deck steel band sheath outside the PBT sleeve pipe, as shown in Figure 1, so just more caused the weight of optical cable heavier, diameter is thicker, more is difficult for the minor radius bending.So existing central-beam tube type fiber optic cable is not suitable for the cloth cable of indoor or outdoors small-bend radius; Because diameter is thick, also be difficult to lay in day by day crowded communication pipeline.And during with route cloth cable, can produce induced voltage, the safety that jeopardizes construction maintenance personnel in steel wire and steel band with the forceful electric power circuit.
The utility model content
In order to overcome defects, the utility model provides a kind of full dielectric central-beam tube type fiber optic cable, and lightweight, diameter is little, and is flexible, there is no induced voltage, is particularly suitable for the optical cable cloth cable that the crowded pipeline of indoor and outdoor and small-bend radius or forceful electric power circuit are gone the same way.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of full dielectric central-beam tube type fiber optic cable, comprise optical fiber, the gap-fill of described optical fiber has fine cream, described optical fiber and fine cream are set in the PBT sleeve pipe, described PBT sleeve pipe is provided with sheath outward, is provided with the FRP reinforcement in described sheath.
Further, the FRP reinforcement is 4 ~ 8, is uniformly distributed in the surrounding in sheath.
Further, the diameter of FRP reinforcement is 1mm ~ 1.5mm.
The beneficial effects of the utility model are: lightweight, diameter is little, flexible, there is no induced voltage, be particularly suitable for the optical cable cloth cable that the crowded pipeline of indoor and outdoor and small-bend radius or forceful electric power circuit are gone the same way, this kind optical cable is compared with the central-beam tube type fiber optic cable of core number with existing, lightweight 40% left and right, diameter little 20% left and right.
Description of drawings
Fig. 1 is the prior art structural representation;
Fig. 2 is the utility model structural representation.
In figure: 1, fine cream; 2, optical fiber; 3, PBT sleeve pipe; 4, sheath; 5, FRP reinforcement; 6, steel wire reinforcement; 7, steel band; 8, waterstop.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail: a kind of full dielectric central-beam tube type fiber optic cable as shown in Figure 2, comprise optical fiber 2, the gap-fill of described optical fiber 2 has fine cream 1, described optical fiber 2 and fine cream 1 are set in PBT sleeve pipe 3, described PBT sleeve pipe 3 is outer is provided with sheath 4, is provided with FRP reinforcement 5 in described sheath 4.FRP reinforcement 5 is 4 ~ 8, depending on optical fibre in optical cable core number, and is uniformly distributed in the surrounding in sheath 4; The diameter of FRP reinforcement 5 is 1mm ~ 1.5mm, determines the diameter of FRP reinforcement 5 according to optical fibre in optical cable core number.
Fig. 1 is the central-beam tube type fiber optic cable of prior art, also indulge bag or be surrounded with one deck waterstop 8 outside PBT sleeve pipe 3, the outer vertical Baogang again of waterstop 8 is with 7 sheaths, the outer sheath 4 that is extruded with black PVC or black PE material of steel band 7, two symmetrical cloth of steel wire reinforcement 6 is placed on the both sides in sheath 4, so just more caused the weight of optical cable heavier, diameter is thicker, more be difficult for the minor radius bending, and steel wire is harder, weight is large, high resilience, not flexible, and steel band and steel wire and forceful electric power circuit near the time can produce induced voltage, jeopardize construction maintenance personnel's safety.
Fig. 2 has lightweight with respect to Fig. 1, diameter is little, flexible, the characteristics that there is no induced voltage, so the full dielectric central-beam tube type fiber optic cable shown in Fig. 2 is particularly suitable for the optical cable cloth cable that the crowded pipeline of indoor and outdoor and small-bend radius or forceful electric power circuit are gone the same way, this kind optical cable is compared with the central-beam tube type fiber optic cable of core number with existing, lightweight 40% left and right, little 20% left and right of diameter save to greatest extent optical cable shared space, and the light characteristics of quality has alleviated staff's work load greatly; Moreover,, lay Shi Buhui with the forceful electric power circuit with route and produce dangerous induced voltage without any metal material due to this kind optical cable the inside.
It is emphasized that: above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
