Background technology
Along with the raising that Cable Core Number is required, optical fibre band optical cable application is more and more extensive, guarantees that it is necessary that optical cable has normal transmission performance under various varying environments.At present, the optical fibre band optical cable being applied in electrical network place and thunder and lightning environment is mainly full medium optical fiber ribbon cable.This kind of optical cable, core number is large, simple in structure, cost is low, practical.Meanwhile, full medium optical fiber ribbon cable also has its intrinsic shortcoming, strengthens original paper and adopts nonmetallic materials, and tensile strength is low and bending property is not good.Provide the structure of buffering because nonconductive optical fiber cable can not add wrinkle steel band etc. in addition, adding casing thickness has certain limitation, and the flattening impact property of optical cable all exists very large limitation.Conventional full medium optical fiber ribbon cable primary structure as shown in Figure 1 (10, little gasket for packing, 2, loose sleeve pipe, 3, fibre ribbon, 4, fine cream, 11, non-metal reinforcement member, 6, cable cream, 7, gasket for packing, 9, oversheath).
Above limitation for conventional all-dielectric optically fibre with optical cable, we develop a kind of novel enhancement type optical fibre band optical cable.Its structure adopts new design concept, and adopts new material, improves well the bending property of optical cable when can ensureing large pulling strengrth, and flattening and impact property to optical cable are also greatly improved.
Summary of the invention
Because the above-mentioned defect of prior art, the invention provides a kind of novel reinforced fiber band optical cable, mainly solve in the construction of the projects such as national grid, conventional all-dielectric optically fibre is with cable machinery insufficient strength and the not good problem of the soft right degree of optical cable, make that optical cable has that simple in structure, core counts that closeness is large, anti-electromagnetic field, conveniently continue, be easy to the features such as installation and maintenance, there is higher physical strength and flexibility simultaneously.Simple process modification, is easy in production realize.
For achieving the above object, the invention provides a kind of novel reinforced fiber band optical cable, comprise PBT sleeve pipe, pine sleeve pipe, fibre ribbon, fine cream, the first aramid fiber bundle, cable cream, gasket for packing, the second aramid fiber bundle and oversheath, fibre ribbon outer wrap has loose sleeve pipe, between pine sleeve pipe and fibre ribbon, be filled with fine cream, fine cream outer gap place is provided with the first aramid fiber bundle, the second aramid fiber bundle and gasket for packing, the diameter of the first described aramid fiber bundle is greater than the second aramid fiber bundle, and the first aramid fiber bundle is arranged on oversheath center, the first aramid fiber bundle and the second aramid fiber bundle outer wrap have PBT (polybutylene terephthalate, polybutyleneterephthalate) sleeve pipe, oversheath and PBT sleeve pipe, pine sleeve pipe, between gasket for packing, be filled with cable cream.
As preferably, described the first described aramid fiber bundle is arranged on optical cable core center, and the first aramid fiber bundle outer ring is circumferentially evenly provided with multiple the second aramid fiber beam tubes.
As preferably, the second described aramid fiber bundle is provided with four, and is symmetrical arranged with respect to the intrafascicular heart of the first aramid fiber.
As preferably, described the first aramid fiber bundle symmetria bilateralis arranges loose sleeve pipe and gasket for packing.
As preferably, described loose sleeve pipe and gasket for packing are two.
Beneficial effect of the present invention: can bear larger pulling force, and withstand voltage and shock resistance, what strengthened environment has adaptively reduced the infringement that barbarous construction may bring optical fiber simultaneously; Because the heat resistance of the new material adopting also improves a lot than traditional material, having reduced the possible high temperature of elect magnetic field must impact the use of optical cable.
Below with reference to accompanying drawing, the technique effect of design of the present invention, concrete structure and generation is described further, to understand fully object of the present invention, feature and effect.
