For the above limitation of conventional all dielectric optical fibre band 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 the bending property of optical cable while can ensureing large pulling strengrth well, there has also been great raising to the flattening of optical cable and impact property.
Utility model content
Because the above-mentioned defect of prior art, the utility model 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 ribbons cable machinery insufficient strength and the not good problem of the soft right degree of optical cable, optical cable is had, and structure is simple, core number closeness large, anti-electromagnetic field, conveniently continue, be easy to the features such as installation and maintenance, has higher physical strength and flexibility simultaneously.Simple process modification, production is easy to realize.
For achieving the above object, the utility model provides a kind of novel reinforced fiber band optical cable, comprise PBT sleeve pipe, Loose tube, fibre ribbon, fine cream, first aramid fiber bundle, cable cream, gasket for packing, second aramid fiber bundle and oversheath, fibre ribbon outer wrap has Loose tube, fine cream is filled with between Loose tube and fibre ribbon, fine cream outer gap place is provided with the first aramid fiber bundle, 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, first aramid fiber bundle and the second aramid fiber bundle outer wrap have PBT (polybutylene terephthalate, polybutylene terephthalate) sleeve pipe, oversheath and PBT sleeve pipe, Loose tube, cable cream is filled with between gasket for packing.
As preferably, described the first described aramid fiber bundle is arranged on optical cable core center, and the first aramid fiber bundle outer ring circumference is evenly provided with multiple second aramid fiber beam tube.
As preferably, the second described aramid fiber bundle is provided with four, and is symmetrical arranged relative to the intrafascicular heart of the first aramid fiber.
As preferably, described first aramid fiber bundle symmetria bilateralis arranges Loose tube and gasket for packing.
As preferably, described Loose tube and gasket for packing are two.
The beneficial effects of the utility model: can bear larger pulling force, and withstand voltage and shock resistance, enhance the adaptive of environment and decrease the barbarous infringement that may bring optical fiber of constructing simultaneously; Because the heat resistance of the new material adopted also improves a lot than traditional material, decreasing the possible high temperature of elect magnetic field must impact the use of optical cable.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
