Description
Technical field
The present invention relates to a kind of optical cable more particularly to a kind of curved optical cables of high-strength bending-resistant.
Background technique
Currently, cable generallys use organic material rubber, plastics etc. as insulating materials, when ignition of cable, insulating layer
It burns totally, while the smog as caused by Plastics Combustion will cause " secondary disaster "；Traditional mineral insulated cable is with magnesia
Cable of the metal oxides such as powder as insulating materials, it has the performances such as excellent fire resisting, explosion-proof, high temperature resistant, guarantees kindling
Route is powered within a certain period of time, improves fireproofing of cable performance, but its complex process, at high cost, while factory length
Also it is restricted；Moisture content longitudinally gos deep into along cable after the moisture absorption, leads to the decline of insulating performance of cable, influences electric property.In addition, electric
Cable bending property is poor, and mounting and installation is inconvenient, and use scope is restricted.
Summary of the invention
The present invention provides that a kind of structure is simple, production cost is low, physical strength is high, using the longevity in order to solve problem above
The curved optical cable of high-strength bending-resistant that life is long, adaptable area is wide.
The technical scheme is that the optical cable includes four communication cores, inner sheaths, waterstop, metal armouring
Layer, oversheath, the communication core includes several fiber optic bundles, and insulation fiber paste, institute are completely filled between several fiber optic bundles
The inner sheath stated, which is extruded in outside four communication cores, constitutes cable core, is arranged waterstop outside the cable core, outside the waterstop
Metal armor layers are set, oversheath is set outside the metal armor layers.
The oversheath is PE oversheath.
Steel wire self-supporting rope is provided in the oversheath.
The metal armor layers are two-sided steel band.
The configuration of the present invention is simple, production cost are low, physical strength is high, long service life, adaptable area are wide.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is fiber optic bundle in figure, and 2 be insulation fiber paste, and 3 be inner sheath, and 4 be waterstop, and 5 be metal armor layers, and 6 be outer shield
Set, 7 be steel wire self-supporting rope.
Specific embodiment
A kind of curved optical cable of high-strength bending-resistant, the optical cable include four communication cores, inner sheaths 3, waterstop 4, metal
Armor 5, oversheath 6, the communication core include several fiber optic bundles 1, completely filling insulation between several fiber optic bundles 1
Fiber paste 2, the inner sheath 3, which is extruded in outside four communication cores, constitutes cable core, and waterstop 4 is arranged outside the cable core, described
Waterstop 4 outside metal armor layers 5 are set, oversheath 6 is set outside the metal armor layers 5.
The oversheath 6 is PE oversheath.
Steel wire self-supporting rope 7 is provided in the oversheath 6.
The metal armor layers 5 are two-sided steel band.
