Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-optical cable, 2-conductor, 3-internal shield, 4-insulating barrier, 5-outer shielding layer, 6-inner sheath, 7-braid, 8-oversheath, 9-insulating barrier.
Embodiment
As shown in Figure 1, constitute by an optical cable 1 and two minor diameter insulated wire cores and three major diameter insulated wire cores, insulated wire cores is twisted into cable core simultaneously, optical cable and two minor diameter insulated wire cores are placed in the crack, limit of insulated wire cores, on cable core, extrude inner sheath 6, braid 7 is set on inner sheath, on braid, extrudes oversheath 8.Optical cable is provided with certain excess fiber length and reinforcing element.The minor diameter insulated wire cores constitutes by insulating barrier 9 is set on the conductor 2.The major diameter insulated wire cores is made of conductor 2, internal shield 3, insulating barrier 4, outer shielding layer 5, and the outer surface of conductor is provided with internal shield, and insulating barrier is set on the internal shield, and outer shielding layer is set on insulating barrier.
The conductor of minor diameter insulated wire cores and major diameter insulated wire cores is the skein line of the many single lines (conductor) behind the wire drawing and annealing, conductor adopts the big drawing machine of the production of German NIEHOFF company to carry out wire drawing and annealing with single line, make behind the wire drawing and annealing line footpath and elongation comparatively unified, stable, ensured the production of cable conductor usefulness single line.The high speed bunch equipment that the production equipment of skein line adopts German NIEHOFF company to produce has guaranteed that the product external diameter is even, pitch unanimity, Stability Analysis of Structures.Make conductor obtain excellent bending resistance, well that conductor diameter is much smaller than the external diameter of conventional equal specification cable conductor simultaneously.
The minor diameter insulated wire cores of cable and the insulating barrier of major diameter insulated wire cores adopt three-layer co-extruded technology, and head adopts three-layer co-extruded pattern, have realized automatic moisture balance technology, and speed of production is fast, constant product quality.
The braid of cable effectively raises the braid mechanical performance by the angle of weave of reasonable control braid, the control weaving quality, guarantee that braid is smooth, do not have the silk of jumping, the particularly processing of joint, can effectively avoid the influence of weaving quality the mechanical performance of cable.
Optical cable is placed in the crack, limit of insulated wire cores, because with stranded stranding of insulated wire cores while, when the core in composite rope is subjected to tension, optical cable and insulated wire cores are simultaneously stressed, the pulling force that is born is just little like this, add optical cable and be provided with certain excess fiber length and reinforcing element, tensile stress can not constitute influence to the transmission performance of optical fiber.Secondly, because optical fiber is relatively more responsive to temperature, cable is in energising and frequent cable is inner when mobile produces a large amount of heats.Be influenced by heat the signal transmission of optical cable for fear of optical fiber can, adopt composite material as cable outer sheath, the thermal endurance and the thermal insulation of cable optical cable unit in crooked and moving process have been guaranteed, meanwhile, during production compound protective layer rubber material is fallen between the slit that into becomes cable core to the full extent, form distinctive cone-shaped, make sheath and cone shape become natural entity, and then play the effect of firm one-tenth cable core, prevent that cable is in the use of reality, frequent move or drag make and form relative slip between cable core and optical cable core and the sheath that frequent friction causes insulating and the accelerated ageing of sheath and the influence that the optical cable signal is transmitted.
Verifying through many correlation tests, if the combination property that the sheath material neither one is good just is difficult to satisfy the requirement of cable in the environment for use of complexity, repeatedly carry out the test and the adjustment of jacket formula, because the cable scope of application is wide, this just requires the sheath of cable not only to have performances such as high strength, high anti-tear, acidproof, oil resistant, also will have very strong lower temperature resistance.Finally obtained having high-strength weather-proof type sheath material through test of many times.Between interior outer jacket, form one in addition and have anti-twist braid.By reasonable control angle of weave, make fibrage be the best in the horizontal holding capacity that vertically reaches of sheath, special formulation design simultaneously and process technology cleverly, with organically bonding between inner sheath, braid and the oversheath three, so just form one and have the excellent mechanical performance and the comprehensive sheath of chemically-resistant characteristic.
