Description
Technical field
The present invention relates to fiber optic cable manufacture field, in particular to a kind of self-bearing type outdoor aerial cable.
Background technology
In daily life, due to light optical fiber conduction loss than electricity in the loss that electric wire conducts much lower, light
Fibre is used as the information transmission of long range.Most optical fiber must be coated before use by several layers of protection structures, the cable after cladding
It is referred to as optical cable, the protective layer and insulating barrier of fiber outer layer can prevent injury of the surrounding environment to optical fiber, Ru Shui, fire, electric shock
Deng.
And photoelectric mixed cable is the cable of optical cable box cable twisting together, i.e., insulation is added in cable configuration and led
Body, integrate optical fiber, transmission of electricity copper cash, because optical transport and electric energy transmission belong to two distinct types of transmission means, transmit
During can't interfere, while can solve equipment electricity consumption and signal transmission issues, both remain ordinary optic fibre
The characteristic of optical cable and the relevant criterion that low voltage power cables can also be met；And extensively using telecommunications network construction, rural area and city
The fiber entering household of the communication base station construction of town remote districts, Urban House community and building, safety monitoring project and other need
The occasion for wanting information to be used simultaneously with electric power.
But in the communication base station cable laying of rural area and cities and towns remote districts, because its is with a varied topography, day gas bar
The factors such as part is changeful, if strong wind and heavy rain is to making somebody a mere figurehead the impact of cable so that the service life of photoelectric mixed cable substantially reduces, when
Often there is the situation of signal or power breakdown, and be limited by the geographical environment of complexity, the maintenance difficulty increase of circuit.
The content of the invention
It is an object of the invention to provide a kind of self-bearing type outdoor aerial cable, is ensureing the transmission of photosignal Simultaneous Stabilization
Meanwhile increase the service life of mixing cable, reduce line maintenance frequency.
The purpose of the present invention is achieved through the following technical solutions：
A kind of self-bearing type outdoor aerial cable, including PE sheaths and the composite steel-plastic belt for being arranged on PE jacket inner walls, in institute
The copper cash that two tangent and simultaneously tangent with composite steel-plastic belt inwall tape insulations are diametrically set of composite steel-plastic belt is stated, is also wrapped
The Loose tube for being arranged on two copper cash both sides and the steel wire with sheath are included, full optical fiber is filled in the Loose tube, and in the steel
Gap location inside plastic composite strip is connected with the steel with sheath in the PE sheaths outer wall filled with the cable cream that blocks water by suspender belt
Rope, and the section of the suspender belt is ellipse.For in the prior art, the optical cable laying of grass roots is vulnerable to the weather of complexity
The influence of change, the sheath of optical cable is caused to be damaged, and the metallic supports in the sheath are easily by cargo sweat, and then shorten light
The problem of cable service life, the present invention first on the inwall of PE sheaths are fixed with composite steel-plastic belt, by two along composite steel-plastic belt
The copper wire for the tape insulation layer being radially arranged is fixed in composite steel-plastic belt, then by internal two copper of Loose tube for filling full optical fiber
The side of silk, the opposite side of two copper wires is placed in using the steel wire with sheath as support member, finally again to composite steel-plastic belt inside
Gap location filled with blocking water cable cream so that composite steel-plastic belt inwall is completely supported, that is, completes the processing of optical cable, simultaneously
It is connected with the outer wall of PE sheaths by suspender belt for supporting overhead steel cable, and sheath is carried on the steel cable to improve it
The section of degree of protection and service life, wherein suspender belt is ellipse, i.e., when high wind impacts cable, suspender belt can be by occurring one
Fixed deformation quantity ensures the amplitude of fluctuation of aerial cable in its safe range to buffer the interaction force between PE sheaths and steel cable
It is interior；And the present invention is in use, and first the steel cable with sheath is fixed on PE sheaths by suspender belt, is then moulded by steel
The supporting construction of composite band, the steel wire with sheath as PE sheaths, and the copper wire of Loose tube and two tape insulation layers protects PE
The inside filling of set, ensures under the multiple protective of PE sheaths and composite steel-plastic belt, the optical fiber in Loose tube will not be by
To the destruction of wild animal and the influence of complicated Changes in weather, and then ensure optical cable in the stable work in rural areas area
Performance, extend the service life of optical cable, while the gap location of multiple optical fiber is filled with fine cream in center sleeve, can be certain
Mechanical damping can also be played a part of while sleeve pipe and optical fiber are fixed in degree, final realize reduces optical cable maintenance
Or the purpose for the frequency changed.
Polyester belt is disposed with along the radial inward of the composite steel-plastic belt, block water on the composite steel-plastic belt inwall
Band.Polyester belt, the waterstop radially-inwardly set gradually along PE sheaths plays multi-stage protection effect, while polyester to sleeve pipe simultaneously
Band can further improve the bend performance of optical cable, and waterstop can prevent that the location part aqueous vapor in water enrichment area from scurrying into optical fiber
In, while ensureing optical fiber stabilization service behaviour, reduce in the optical cable probability that optical fiber is damaged when to by extraneous stress.
The 1/2 of the copper wire diameter of a diameter of tape insulation of multigroup Loose tube.Preferably, the diameter of Loose tube is set
It is set to the half of the copper wire diameter of tape insulation layer so that it is compacter in the middle part overall structure of PE sheaths, will not be because outer
The stress variation on boundary and produce excessive deformation, reach extend optical cable service life purpose.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is used as the supporting constructions of PE sheaths by composite steel-plastic belt, the steel wire with sheath, and Loose tube and
The copper wire of two tape insulation layers fills the inside of PE sheaths, ensures under the multiple protective of PE sheaths and composite steel-plastic belt,
Optical fiber in Loose tube will not be influenceed by the destruction of wild animal and the Changes in weather of complexity, and then ensure optical cable
In the service behaviour that rural areas area is stable, extend the service life of optical cable, while in center sleeve between multiple optical fiber
Fine cream is filled with gap, mechanical damping can also be played while sleeve pipe and optical fiber can be fixed to a certain extent
Effect, it is final to realize the purpose for reducing optical cable maintenance or the frequency changed；
2nd, the polyester belt of the invention radially-inwardly set gradually along PE sheaths, waterstop play multi-stage protection to sleeve pipe simultaneously
Effect, while polyester belt can further improve the bend performance of optical cable, waterstop can be prevented in the location part of water enrichment area
Aqueous vapor is scurried into optical fiber, while ensureing optical fiber stable service behaviour, reduces that optical fiber is damaged when to by extraneous stress in optical cable
Probability；
3rd, the diameter of Loose tube is arranged to the half of the copper wire diameter of tape insulation layer by the present invention so that in PE sheaths
Middle part overall structure it is compacter, excessive deformation will not be produced because of the stress variation in the external world, reached and extended optical cable and make
With the purpose in life-span.
