Description
Technical field
The present invention relates to communications optical cable technical field, more particularly to a kind of abnormity FRP armourings are nonmetallic to be prevented nibbling
Tooth animal optical cable and its processing technology.
Background technology
Currently, the erection of communications optical cable is more and more, it is serious that communications optical cable enters the rodents disaster such as forest, mountain area
Area it is also more and more.Rodent, due to its front tooth is very flourishing and can constantly grow and part rodent because
Object bite with the habit for keeping its tooth sharp, and peculiar gas contained in communications optical cable sheath becomes it often
The object to bite, therefore communications optical cable circuit frequently suffers from rodent in some occasions and bites and influence communication quality, even
Lead to communication disruption.
Currently, the anti-rodent method of domestic optical cable has two kinds of chemical method and Physical.
The advantages of chemical method is that anti-rodent drug or additive are added in protecting sleeve of optical cable, this method is expense
With cheap, production technology is fairly simple, but will produce some in process to human body and the harmful pollution of environment, simultaneously
The drug or additive being added in protective cover material can gradual separate out over time, thus influence the anti-grinding tooth of optical cable
Animal lifespan, and the drug of separate out or additive pollute the environment, and are unfavorable for environmental protection.
And the mode of Physical generally use armouring protection, there are two kinds of metal armouring and non-metallic sheath, makes rodent
Tooth is difficult to be gnawed through, high-strength in the anti-bite experiment of known optical cable to achieve the purpose that protect optical cable in armor
The steel band of degree has preferable anti-bite effect, but also some researches show that bite mark makes the steel band being exposed in external environment add simultaneously
Play corrosion, most of optical cables can be all etched in a short time.
Non-metal armored optical cable mainly has FRP armouring methods at present, is that formation rounding is tight after several circular rod-shapeds are twisted
Close armouring achievees the purpose that anti-rodent bites with this, but is substantially line between every FRP of this method and connects
It touches, contact area is small, while the structure of circle FRP provides the impetus that rodent tooth bites, once oversheath is broken
It is bad, FRP it is difficult to ensure that its some time be snapped after be not destroyed.
Therefore, how a kind of special-shaped FRP armouring nonmetallic anti-rodent light of the rodent without the impetus that bites is provided
The problem of cable and its processing technology are those skilled in the art's urgent need to resolve.
Invention content
In view of this, the present invention provides a kind of nonmetallic anti-rodent optical cable of abnormity FRP armourings, it is utilized Z-shaped
FRP bars, which be twisted, envelopes optical cable core, and carrying out effectively anti-rodent using Physical bites, and cable configuration is simple,
It is effectively prevented the destruction of rodent, existing environmental applications requirement is disclosure satisfy that, extends the service life of optical cable, reduction is nibbled
Fiber optic cable communications failure caused by tooth animal bites.
To achieve the goals above, the present invention adopts the following technical scheme that：
A kind of nonmetallic anti-rodent optical cable of abnormity FRP armourings, including：Optical cable core, abnormity FRP bars armor and
Outer jacket, the optical cable core are coated with the abnormity FRP bar armors, and the abnormity FRP bar armors outer cladding is
State outer jacket；Wherein, the abnormity FRP bar armors are tubulose, including more Z-shaped FRP bars, and the adjacent Z-type FRP bars
It is mutually twisted.
The nonmetallic anti-rodent optical cable of abnormity FRP armourings disclosed by the invention, not only rodent bite without putting forth effort
Point, and can also play anti-tensile, lateral pressure resistant, anti-retraction, impact resistance, it is moisture-proof the effects that, relatively existing circular rod-shaped FRP armours
Optical cable is filled, the smaller cable outer diameter of existing abnormity FRP bars armored optical cable is the function of can reach anti-rodent and bite.
Preferably, the abnormity FRP bars are fiberglass-reinforced plastic lever.
Preferably, tubular type cable core or layer-twisted type cable core centered on the optical cable core.
The invention also discloses a kind of nonmetallic anti-rodent optical cables of abnormity FRP armourings, include the following steps：
Step 1：The radical and size of Z-shaped FRP bars are calculated according to the diameter of optical cable core and properties of optical fiber cable requirement；
Step 2：Z-shaped FRP bars are twisted, armouring forms abnormity FRP bar armors outside the optical cable core；
Step 3：While carrying out the abnormity FRP bar armors cladding, is tightened using bundle yarn and be fixed on institute
It states outside optical cable core；
Step 4：The optical cable core that FRP bar armourings are completed by step 3 is released from pay off rack, is built in extruding
In formula extruded mould；
Step 5：Outer sheath material is extruded in by squash type extruded mould outside the optical cable core that step 3 is formed, and extrudes shape
At outer jacket.
It can be seen via above technical scheme that compared with prior art, the present disclosure provides a kind of abnormity FRP armours
Nonmetallic anti-rodent optical cable is filled, is utilized that Z-shaped FRP bars are twisted to envelope optical cable core, is carried out using Physical effectively anti-
Rodent bites, and cable configuration is simple, is effectively prevented the destruction of rodent, disclosure satisfy that existing environmental applications are wanted
It asks, extends the service life of optical cable, be further reduced fiber optic cable communications failure caused by rodent bites；And it can also play
Anti-tensile, lateral pressure resistant, anti-retraction, impact resistance, it is moisture-proof the effects that.
The invention also discloses the processing technology of the nonmetallic anti-rodent optical cable of special-shaped FRP armourings, processing technology letters
It is single, it is easy to implement.
