Description
Technical field
The present invention relates to a kind of self-bearing type anti-rat-bite optical cable and its manufacture method, belong to optic communication transmission technique field.
Background technology
Self-supporting tensile elements for the overhead non-metallic optical fiber cables of self-supporting are usually to spin synthetic fibre, and these optical cables are after the completion of laying
It can be stung by various muroids and some birds birds and peck invasion and attack, so as to progressively lose self-bearing ability.By the use of glass fiber yarn as
The tensile elements of optical cable, although there is certain protection against rodents ability, self-supporting tensile elements are used as, it is whole due to one itself can not be turned into
Body, once oversheath is damaged, its self-supporting tensile capacity can drastically decline, and can not resist the puncture of muroid tooth.Using glass
Glass fiber band mode protection against rodents, its material hardness are limited to thickness, and its manufactured optical cable is stiff, and reel stays bending radius
It is especially big, to using and laying brings inconvenience.By adding the chemical protection against rodents mode of pungent element in sheath, not only producing
When can produce a large amount of penetrating odors, pollute surrounding air, have a strong impact on producers' normal work, while with additive
Progressively spread, rodent-proof characteristic can also decline therewith.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of self-bearing type for above-mentioned the shortcomings of the prior art
Anti-rat-bite optical cable and its manufacture method, cable configuration setting is rationally simple, and not only the anti-unfirmly closing performance of mouse bite preventing is strong, self-supporting tension
Performance is high, and good bending property, is easily installed laying, and manufacture craft is easy.
The present invention is that optical cable technology scheme is used by solving the above problems：Include cable core and oversheath, its feature
Be to be provided with outside cable core it is anti-bite it is anti-peck splicing layer, described anti-bite anti-splicing layer of pecking circumferentially is arranged by flat-shaped FRP bars along cable core
Row are spliced, and anti-bite anti-peck splices layer outer cladding oversheath.
By such scheme, described flat-shaped FRP bars width is 2.0~5.0mm, and thickness is 0.5~1.2mm, and surface is hard
It is Gu smooth.
By such scheme, thinning described flat-shaped FRP bars both sides edge withdraw is in blade-like.
By such scheme, described flat-shaped FRP bars are formed by glass fibre and resin formulations solidification.
By such scheme, described anti-bite anti-splicing layer of pecking is spliced by flat-shaped FRP bars along cable core circumference close-packed arrays,
Adjacent flat-shaped FRP bars at intervals of 0~1.0mm.
By such scheme, the stranded mode that described flat-shaped FRP bars are twisted with SZ or S is twisted is covered in cable core surface, is twisted section
Away from for 100~500mm.
By such scheme, water blocking yarn waterproof layer is provided between splicing layer in cable core and anti-bite anti-peck.
By such scheme, described cable core is layer-twisted type cable core or skeleton cable core.
By such scheme, described layer-twisted type cable core is half-dried layer-twisted type cable core, and half-dried layer-twisted type cable core includes nonmetallic
Center reinforcemen and the Loose tube being stranded in around center reinforcemen, optical fiber is set with Loose tube, and fills fine cream, outside cable core
Winding, which blocks water, pricks yarn or parcel blocks water band.
By such scheme, hawser is provided with out in oversheath.
The manufacture method technical scheme of optical cable is：
Cable core is first made, and yarn or the band that blocks water parcel cable core are pricked with blocking water；
Further around wrap it is anti-bite it is anti-peck splicing layer, by flat-shaped FRP bars in a manner of S is twisted or SZ is twisted around being wrapped in outer layer of cable core, and pass through
Prick yarn or band is tied up；
Extrude oversheath：The cable core for having tied up flat-shaped FRP bars is passed through into oversheath mould, with outer jacket extruding machine
Agent oversheath.
The beneficial effects of the invention are as follows：1st, flat-shaped FRP bars are not only firm smooth, and gather in the outer layer of cable core, formed
It is effective it is anti-bite it is anti-peck splicing layer, it is difficult to be gnawed through to prevent damaged by rats and unfirmly closing, muroid using the hardness and puncture ability of itself
And undermine cable core；When a flat FRP bar is bitten, energy puncture muroid oral cavity is pierced on its hard sharp side, it is abandoned into one
Step, which is stung, gnaws, therefore optical cable is possessed the anti-unfirmly closing performance of very strong mouse bite preventing；2nd, flat-shaped FRP bars can be used as self-supporting tensile elements with it is outer
Sheath combines to form a compound outer jacket, the outer jacket not only have it is excellent it is anti-gnaw it is anti-peck performance, and possess powerful
Tensile capacity and anti-collapse ability, the self-supporting performance of optical cable can be effectively improved；3rd, structure setting advantages of simple of the present invention, protective
Can be strong, low manufacture cost, optical cable is soft, good bending property, easy to use and laying；4th, using physics anti-bite structure, it is easy to make
Make, it is free from environmental pollution.
