Description
Technical field
The utility model belongs to communications optical cable production technical field, is specifically related to a kind of photoelectric mixed cable for adverse circumstances.
Background technology
The power network investment of Future Ten year is huge, according to power industry " 12 " Report on Planning Research, in the middle of nearest two five-year plans, China's Electricity Investment total value is by tall and big 11.1 trillion yuan, wherein " 12 " period is by input 5.3 trillion yuan, drop into most 5.8 trillion yuan during 13,5.7 trillion yuan will be had to invest power construction, 5.4 play one invests power grid construction.Rise electrical network will with power optical fiber register one's residence advance net fusion more, the EPON of OPDC adds PFTTH.Only increase the cost less than 10% than FTTB+LAN, integrated cost but reduces by 40%.Only the average annual potential need of New Dwelling to photoelectric mixed cable have just exceeded 35,000,000,000 yuan, and estimate universal 4,300,000 families in 2015, market can reach 7,000,000,000.
Due to the transformation of application scenarios, huge hidden danger will be there is in conventional photoelectric mixed cable in the application of city and community, the mechanical performance index such as the bending radius to product, pulling force, water resistance, stability and the performance such as anti-interference is needed to optimize and revise further, to adapt to existing environmental requirement.
Utility model content
The utility model is in order to solve the problem of prior art, provide a kind of high-performance photoelectric mixed cable for adverse circumstances, make the mechanical performance index such as the bending radius of product, pulling force, water resistance, stability and the performance such as anti-interference obtain further Optimization and tuning.
A kind of high-performance photoelectric mixed cable described in the utility model, comprises half dry type centering ring around the cable core of structure and the oversheath that is extruded in outside cable core, between cable core and oversheath, is provided with waterstop; Described cable core comprises light unit, feed line and FRP reinforcement, and described FRP reinforcement is arranged on the center of cable core, and light unit and cable are twisted into cable core centered by the FRP reinforcement of center; Gasket for packing and water blocking yarn is provided with in the gap of cable core.
Further improvement, described light unit is one.
Further improvement, described feed line is two.
Further improvement, described gasket for packing is two, is separately positioned on the gap between light unit and two feed lines.
Further improvement, described water blocking yarn is distributed in the gap in cable core between every two elements in rounded projections arranged mode.
Further improvement, described light unit by be arranged on center FRP reinforcement, be that the two-layer optical cable that arranges with one heart and the sheath be extruded in outside two-layer optical cable combine with FRP reinforcement.
Further improvement, described optical cable is made up of central optical fiber and the aramid fiber layer be extruded in outside optical fiber.
Further improvement, described aramid fiber layer is made up of many aramid yarns.
Compared with prior art, the utility model beneficial effect is:
1, the utility model adopts half dry type centering ring around structure, effectively raises the uniformity that light unit is stressed; Light unit is formed around FRP by the single fiber cable with 3 1100dtex aramid yarns, this kind of half dry type structure is compared with conventional beam tube, add FRP reinforcement, and every root single fiber cable is all containing aramid yarn, effectively improve the mechanical performance of product, half dry type structure, due to not containing ointment, improves the environmental-protecting performance of product and the compatibility with electric unit.
2, the tensile property of the single single fiber cable of this product: long-term 60N, fiber strain≤0.15%; Short-term: 100N, fiber strain≤0.35% optical fiber additional attenuation is without significant change.Utilize the effect of this kind of structure and FRP central reinforce member, compared with can not bearing pulling force with conventional photo mixing cable light unit beam tube, tensile property will have obvious lifting.
3, there is excellent block-water performance: in the gap of cable core and sheath, adding 15 specifications is the water blocking yarn of ZZS4.0, and is wrapped up by whole cable core with waterstop when stranding.
4, the finished product temperature good cycle (-40 DEG C ~+80 DEG C) of this product, because optic fibre force increases causing the additional attenuation of product, therefore the temperature Cycle improving product is had higher requirement to material, this hard-pressed bale adopted and single core cable sheath, all adopt the sheath that the protective cover material of heatproof resisted shrinkage is formed, under the working condition of (-40 DEG C ~+80 DEG C), the additional attenuation≤0.1dB/km of this product.
5, for avoiding oversheath to shrink, product is impacted, thermal contraction performance≤5% of this product oversheath.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
