Description
Technical field
The present invention relates to a kind of optical cable more particularly to a kind of moisture-proof optical cables of high water 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 moisture-proof optical cable of high water resistant that life is long, adaptable area is wide, water-blocking moistureproof effect is good.
The technical scheme is that the optical cable includes the six roots of sensation communication core, metal center strengthening core, block water expansion
Yarn, bilayer block water twining package tape, metal armor layers and oversheath, and the metal center strengthening core setting is described at optical cable center
The setting of six roots of sensation communication core etc. point heart strengthening core periphery, the communication core include that several optical fiber and setting exist in a metal
The optical fiber loose tube of outer fiber, described blocks water expanded yarns setting between six roots of sensation communication core, the six roots of sensation communication line
Bilayer is extruded outside core jointly to block water twining package tape, is provided with metal armor layers outside the twining package tape, outside the metal armor layers
It is provided with oversheath.
The metal armor layers are two-sided aluminium strip armor.
The oversheath is PE oversheath.
The configuration of the present invention is simple, production cost are low, physical strength is high, long service life, adaptable area are wide, water-blocking moistureproof effect
Fruit is good.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
1 is optical fiber in figure, and 2 be Loose tube, and 3 be the expanded yarns that block water, and 4 be metal center strengthening core, and 5 to be that bilayer blocks water wrapped
Band, 6 be metal armor layers, and 7 be oversheath.
Specific embodiment
A kind of moisture-proof optical cable of high water resistant, the optical cable include the six roots of sensation communication core, metal center strengthening core 4, block water it is swollen
Swollen yarn 3, bilayer block water twining package tape 5, metal armor layers 6 and oversheath 7, and the metal center strengthening core 4 is arranged in optical cable
The heart, heart strengthening core 4 is peripheral in a metal for point setting such as described six roots of sensation communication core, and the communication core includes several optical fiber
1 and the optical fiber loose tube 2 that is arranged in optical fiber 1 outside, the setting of expanded yarns 3 that blocks water communicates between core in the six roots of sensation, described
Six roots of sensation communication core outside extrude bilayer jointly and block water twining package tape 5, be provided with metal armor layers 6 outside the twining package tape 5, it is described
Metal armor layers 6 outside be provided with oversheath 7.
The metal armor layers 6 are two-sided aluminium strip armor.
The oversheath 7 is PE oversheath.
