Abstract
The utility model discloses a directly-buried tension and compression resistant abrasion-proof photoelectric composite cable. A cable core of the cable is formed by concentrically twisting an optical fiber loose tube and a conductor with an insulated layer, a filling rope and water resistant factice are disposed in the gap of the cable core, and a center reinforcing part is arranged at the center of the cable core. An aluminum-plastic composite belt in longitudinal lapping mode, an inner jacket in extruded mode and a steel-plastic composite belt in longitudinal lapping mode are sequentially arranged outside the cable core, a second inner jacket is disposed outside the steel-plastic composite belt in extruded mode, and a thin round steel wire armor layer and a cable outer jacket are sequentially arranged outside the second inner jacket. The photoelectric composite cable is capable of being directly laid in a high-abrasion environment of sandy soil, broken stones and the like by adopting the directly-buried mode, and has the advantages of being tension and compression resistant, longitudinally water-proof and abrasion-proof.
Description
Technical field:
The utility model relates to a kind of direct burial tension anti-pressure and abrasion-proof photoelectricity composite cable.
Background technology:
Lay the photoelectricity composite cable through pipe method, not only cost is higher, and it is also bigger to lay difficulty.When adopting direct-buried mode to lay; Common pipe formula photoelectricity composite cable lacks effectively radially lateral pressure resistant protection again, and fracture of photoelectricity composite cable inner fiber or loss are increased, and the common photoelectric composite cable can't be born excessive static state and dynamic tension simultaneously; Also can't bear lay with use in friction; Thereby possibly cause outer jacket damaged, making intakes in the cable causes circuit to damage or short circuit, and then influences the useful life of photoelectricity composite cable.
Summary of the invention:
For overcoming the defective of prior art; The purpose of the utility model is to provide a kind of direct burial tension anti-pressure and abrasion-proof photoelectricity composite cable; This photoelectricity composite cable can adopt the mode of direct-burried directly to be laid under the high abrasion environments such as sandy soil rubble, has tension, resistance to compression, vertically blocks water and wear-resisting characteristic.
The utility model technical solution problem adopts following technical scheme:
A kind of direct burial tension anti-pressure and abrasion-proof photoelectricity composite cable, said cable conductor is formed by the conductor concentric stranding of optical fiber loose tube and tape insulation layer, is provided with gasket for packing and greasy for preventing water in the cable core gap, and the cable core center is provided with central reinforce member; Vertically successively outside said cable core be surrounded by aluminium-plastic tape, be extruded with inner sheath, vertically be surrounded by composite steel-plastic belt, outside said composite steel-plastic belt, be extruded with second inner sheath, outside said second inner sheath, be provided with thin round steel wire armour, cable jacket successively.
The design feature of the utility model also is:
Between said inner sheath and said composite steel-plastic belt, be filled with greasy for preventing water.
Said central reinforce member is the phosphatization steel wire.
Said oversheath is the polyurethane oversheath.
The inner core of said optical fiber loose tube is a colored optical fiber, between said colored optical fiber, is provided with the thixotropy filling paste.
Compared with present technology, the beneficial effect of the utility model is embodied in:
The utility model is stranded in optical fiber loose tube and insulated wire around the central reinforce member through the stranded mode of SZ, and successively with the vertical bag of aluminium-plastic tape, inner sheath, composite steel-plastic belt, second inner sheath, wire armoring layer and the wear-resisting oversheath of polyurethane or be extruded on the cable core.This utility model is not only practiced thrift construction cost, has also reduced difficulty of construction, can also effectively protect optical fiber to avoid the measuring pressure of hard intensity, avoids the damage to optical fiber of excessive lateral pressure.Composite steel-plastic belt and wire armoring layer can improve the resistance to compression and the tensile property of photoelectricity composite cable; The polyurethane oversheath has good anti-wear performance; These performances assurance photoelectricity composite cables can directly be laid under the complicated geographical environment; Save duration and construction cost, and enough tension, resistance to compression is provided, blocks water and wear-resistant protection for the photoelectricity composite cable.
Description of drawings:
Fig. 1 is the cross section structure sketch map of the utility model cable.
Label among the figure: 1 oversheath, 2 wire armoring layers, 3 second inner sheaths, 4 composite steel-plastic belts, 5 greasy for preventing water; 6 central reinforce members, 7 optical fiber loose tubes, 8 colored optical fibers, 9 aluminium-plastic tapes, 10 insulating barriers; 11 conductors, 12 gasket for packings, 13 thixotropy filling pastes, 14 inner sheaths.
Below pass through embodiment, and combine accompanying drawing that the utility model is described further.
Embodiment:
Embodiment: combine Fig. 1; The direct burial tension anti-pressure and abrasion-proof photoelectricity composite cable of present embodiment; Cable conductor is formed by conductor 11 concentric strandings of optical fiber loose tube 7 and tape insulation layer 10, is provided with gasket for packing 12 and greasy for preventing water 5 in the cable core gap, and the cable core center is provided with central reinforce member 6; Vertically successively outside cable core be surrounded by aluminium-plastic tape 9, be extruded with inner sheath 14, vertically be surrounded by composite steel-plastic belt 4, outside composite steel-plastic belt 4, be extruded with second inner sheath 3, outside second inner sheath 3, be provided with thin round steel wire armour 2, cable jacket 1 successively.
In specifically being provided with; Between inner sheath 14 and composite steel-plastic belt 4, be filled with greasy for preventing water 5, central reinforce member 6 adopts the phosphatization steel wire, and oversheath 1 adopts the polyurethane oversheath; The inner core of optical fiber loose tube 7 is a colored optical fiber 8, between colored optical fiber, is provided with thixotropy filling paste 13.
Colored optical fiber 8 and thixotropy filling paste 13 are processed optical fiber loose tube 7 through the secondary coating operation, and the surplus length of loose sleeve pipe 7 is 2～3 ‰, makes the optical fiber pull resistance improve greatly; Afterwards with insulated conductor through the stranded stranding mode of SZ be stranded in phosphatization steel wire central reinforce member 6 around; Stranded greasy for preventing water 5 or the vertical bag waterstop of filling later, the cable core gap is provided with gasket for packing 12, and vertical then alclad plastic composite strip 9 is as moisture-proof layer; On aluminium-plastic tape, extrude inner sheath 14, play the insulation blocking effect.Vertical Baogang's plastic composite strip 4 or wrapped steel band are filled greasy for preventing water 5 or waterstop simultaneously, and then are extruded second inner sheath 3 as armour on inner sheath, the thin round steel wire armour 2 of the wrapped one deck of spiral on second inner sheath at last, and extrude one deck oversheath 1.In the above structure, central reinforce member 6 and thin round steel wire armour 2 partly play the tension effect as the main load of photoelectricity composite cable, have constituted the tension unit of photoelectricity composite cable.All fill greasy for preventing water or waterstop between each layer and the layer, reached the vertical and horizontal block-water effect of photoelectricity composite cable.Composite steel-plastic belt, steel band and thin round steel wire armour play the effect of lateral pressure resistant jointly, can obviously improve the lateral pressure resistant performance of photoelectricity composite cable.Oversheath adopts the high abrasion polyurethane material, can effectively improve the resistance to wear of photoelectricity composite cable.
