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 easy to laying and difference, 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 coated with inner sheath in cable core, be provided with outside inner sheath it is anti-bite it is anti-peck splicing layer, it is described it is anti-bite it is anti-peck splicing layer by
Flat-shaped FRP bars are spliced along inner sheath circumferential array, 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 firm
It is 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, it is described it is anti-bite it is anti-peck splicing layer by flat-shaped FRP bars along the splicing of inner sheath circumference close-packed arrays and
Into, 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 inner sheath outer surface,
Twisting pitch is 100 ~ 500mm.
By such scheme, water blocking yarn waterproof layer is provided between cable core and inner sheath.
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 and inner sheath.
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；
Agent inner sheath, cable core is at the uniform velocity passed through into inner sheath mould, inner sheath is extruded outside cable core with extruding machine；Further around bag
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 inner sheath periphery,
And tied up by pricking yarn or band；
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 processed.
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
Oversheath 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 very strong
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, protection
Performance is strong, low manufacture cost, and optical cable is soft, good bending property, easy to use and laying；Inner sheath is set to be easy to point of optical cable
Discrimination, optical cable is also set to possess more preferable barrier propterty；4th, using physics anti-bite structure, it is easy to make, it is free from environmental pollution.
