Abstract
The utility model provides a layer winding type optical cable having a steel wire embedded sheath, which comprises a cable core, a polyethylene sheath that is covered onto the cable core, a central reinforcing steel wire arranged along the cable core axle of the cable core, at least one loose sleeve that is positioned on the circumference of the central reinforcing steel wire, a charging ointment layer that is positioned between the loose sleeve and the central reinforcing steel wire, at least two loose sleeve optical fibers positioned inside the polyethylene sheath. The utility model not only can improve the pressure resistant strength of the optical cable and the extension resistant strength of the sheath as well as the lower temperature performance, but also can save the pipeline resources and reduce the communicating project constructing cost.
Description
Technical field:
The utility model is relevant with optical cable, and especially to carry the steel wire floor stranded cables secretly relevant with sheath.
Background technology:
Along with rolling up that the present communication information needs, will inevitably strengthen the optical fiber communication engineering construction, the optical cable use amount also can increase thereupon greatly, make the communication pipe resource anxiety in city, therefore, can reduce cable outer diameter under the prerequisite that guarantees the every performance index of optical cable, the utilization factor that improves the communication pipeline is optic cable design and manufacturing engineering technician's a target as far as possible.Existing layer-stranding cable is generally with the strengthening core centering, be subjected to the requirement of optical cable mechanical property, the area of section of the strengthening core at center can only be within the specific limits, thereby limited the sectional area of whole optical cable, so cable outer diameter is generally bigger, the user wastes conduit resource in laying use, improve the communication engineering construction cost.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of and can improve compressive strength and sheath tensile strength, improve cryogenic property, save conduit resource, reducing the sheath of communication engineering construction cost and carry the steel wire floor stranded cables secretly.
The purpose of this utility model is achieved like this:
The utility model sheath is carried the hank knotting layer-stranding cable secretly and is comprised cable core, be sleeved on the pe sheath on the cable core, axially there is the center to strengthen steel wire along cable core in the cable core, be positioned at the center and strengthen at least one loose sleeve pipe of steel wire periphery, be positioned at loose sleeve pipe, the factice for filling layer between steel wire is strengthened at the center, in the pine sleeve pipe at least two loose tube fibers are arranged, be positioned at the greasy for preventing water layer between loose tube fiber, at least two steel wires are arranged in the pe sheath, loose tube fiber can be sent into loose sleeve pipe with stranded mode or the straight mode of putting into of two-way sinusoidal SZ, the material of pine sleeve pipe can be polybutylene terephthalate PBT, polypropylene PP, polyurethane PA, polycarbonate or other polymkeric substance, the pine sleeve pipe can also can be that the stranded mode of the one-way spiral center that is distributed in is strengthened around the steel wire in the stranded mode of SZ, the center is strengthened steel wire and is positioned at the cable core center, and steel wire in the pe sheath and center are strengthened steel wire and constituted reinforcing element.
Between above-mentioned pe sheath and cable core metal compound belt is arranged.
The band that is tightly packed on the cable core is arranged between above-mentioned metal compound belt and cable core, be contained in the tygon inner sheath on the band periphery, be contained in the band that blocks water on the tygon inner sheath periphery.
Above-mentioned band is a composite band.
In the above-mentioned cable core gasket for packing is arranged, loose sleeve pipe, gasket for packing all are distributed in the center and strengthen on the steel wire periphery.
Steel wire in the above-mentioned pe sheath is two, and symmetrical parallel is arranged in pe sheath vertically.
Steel wire in the above-mentioned pe sheath is two, and symmetrical parallel is arranged in pe sheath vertically.
Steel wire in the above-mentioned pe sheath is four, and symmetrical parallel is arranged in pe sheath vertically.
Referring to Fig. 1～Fig. 4, center reinforcement steel wire has constituted reinforcing element jointly in steel wire in the utility model pe sheath and the cable core, the external diameter that makes the center strengthen steel wire can suitably reduce, thereby the external diameter of whole optical cable can reduce, and can improve the utilization factor of communication pipe resource like this.With the GYTA optical cable is example, uses the utility model structure, the optical cable of same core number, and the utility model structure optical cable sectional area can reduce by 20～30%, that is to say it can is that the utilization factor of communication pipe resource has improved 20～30%.Make optical cable jacket shrinkage in low temperature environment be subject to the linear expansion coefficient of steel wire owing to be entrained with steel wire in the pe sheath simultaneously, thereby improved the cryogenic property of product.
The utility model optical cable compressive strength and sheath tensile strength height, the cryogenic property height is convenient to user's a large amount of conduit resources of saving in laying use, reduces the Communication Engineering construction cost.The utility model can be used for outdoor also can be used for indoor.
