Abstract
The utility model provides an anti-peck all-dielectric self-supporting optical cable which can prevent cable from being pecked by birds. The cable comprises optical fibers, a loose tube, fiber paste, a central reinforcer, an inner sheath layer, an aramid fiber layer and an outer sheath layer, wherein the loose tube containing the optical fibers is arranged surrounding the central reinforcer, the fiber paste 2 is arranged inside the loose tube, the loose tube is binded by binding yarns, a cable core filler is arranged between the inner sheath layer and the loose tube, the aramid fiber layer is uniformly distributed around the inner sheath layer 7, and the outer sheath layer is made of nylon sheath material. The binding yarns 6 are internally provided with filling ropes. According to the anti-peck all-dielectric self-supporting optical cable, the mechanical strength of the optical cable is improved while the purpose of preventing bird pecking is achieved.
Description
Technical field
The utility model relates to the optical cable technology field, and it is that a kind of nylon that adopts protects the All Dielectric self-support that material reaches anti-unfirmly closing purpose outward in definite saying.
Background technology
Along with developing rapidly of power communication cause, All Dielectric self-support relies on its erection mode easily, become each big optical cable producer requisite competition chip in competitive market, common All Dielectric self-support is a kind ofly all to be made up of dielectric material, self comprise necessary support system, can directly hang on the non-metallic optical fiber cables on the electric force pole tower, be mainly used in the communicating route of aerial high voltage power transmission system, also can be used for the multiple area of thunder and lightning, the built on stilts communication line that lays under the environment such as large span, find by inquiry, the All Dielectric self-support that has set up has by birds pecks leakage phenomenon, the common outer material performance of protecting can't be resisted birds and must be pecked evil, cause outer protecting and even the cable core breakage, hindered communication transmission quality, therefore need look for a kind of high-performance to protect material outward is the development trend of industry.Draw the characteristics that the nylon sheath wire material has wear-resisting, high strength, high tenacity through research repeatedly, can resist birds fully to the infringement of optical cable.
Summary of the invention
The purpose of this utility model provides a kind of anti-unfirmly closing All Dielectric self-support, it is characterized in that the outer protective sleeve material of optical cable adopts the nylon sheath wire material to replace original PE sheath, reaches the effect of anti-unfirmly closing.
The technical solution of the utility model: it comprises optical fiber, loose sleeve pipe, fine cream, central reinforce member, sheath, aramid layers, outer jacket, the loose sleeve pipe that contains optical fiber is centered around around the central reinforce member, in the pine sleeve pipe fine cream is arranged, pine sleeve pipe 3 is pricked the yarn wrapping, between sheath and the loose sleeve pipe, the cable core filling material is arranged, it is characterized in that: aramid layers is evenly distributed in around the sheath, and last outer jacket adopts the nylon sheath wire material.Prick in the yarn gasket for packing is arranged.
The beneficial effects of the utility model:
1. adopt nylon sheath wire material All Dielectric self-support, prevent that the optical cable surface from being pipped by birds.
2. this optical cable does not have metal construction, and anti-electromagnetic performance is good.
3. fill extraordinary fine cream in the loose sleeve pipe, 100% cable core is filled total cross-section and is blocked water, and humidity resistance is good.
4. optic cable diameter is little, in light weight, has reduced ice slush and wind-force to the influence of optical cable, has also alleviated the load of shaft tower and stilt.
5. construction operation is simple.Exempt vertical rod, set up messenger wire and hung the program of pulley laying optical cable at messenger wire, can be as line of electric force, field, ditch and river directly fly over.
6. accurately control optical fiber excess length and guaranteed that optical cable has good tensile property and temperature characterisitic.
7. add aramid fiber in the cable configuration, as the main load unit of optical cable, improve the tensile strength of optical cable.

Embodiment
The utility model embodiment: it comprises optical fiber, loose sleeve pipe, fine cream, central reinforce member, sheath, aramid layers, outer jacket, the loose sleeve pipe 3 that contains optical fiber 1 is centered around around the central reinforce member 4, in the pine sleeve pipe 3 fine cream 2 is arranged, pine sleeve pipe 3 is pricked yarn 6 wrappings, between sheath 7 and the loose sleeve pipe 3, cable core filling material 5 is arranged, aramid layers 8 is evenly distributed in around the sheath 7, and last outer jacket 9 adopts the nylon sheath wire material.Prick in the yarn 6 gasket for packing 10 is arranged.
This product selects for use the layer-twisted type structure to produce:
1, optical fiber pine cover lining
For not being subjected to external action, protection optical fiber outside optical fiber coating, do not squeeze into the process of one deck suitable plastic pine cover and filled composite cushion.
2, stranding
Stranded to together with loose sleeve pipe, gasket for packing, reinforcement (FRP) nature, excessive for preventing yarn-binding tension, be adjusted to inertial states, purpose be element is closed as a whole.
3, inner sheath
The sheath of optical cable is used for protecting cable core, makes cable core avoid the influence of extraneous mechanical effect and environmental baseline.
4, protect aramid fiber
Aramid layers is the main load unit of All Dielectric self-support, mainly carries the weight of the built on stilts back of optical cable optical cable self and icing, wind pendulum power etc.
5, oversheath
The restrictive coating of optical cable is to protect sheath, makes inner member avoid the influence of extraneous mechanical effect and environmental baseline, and here we select for use the nylon sheath wire material to finish oversheath production, reaches the purpose that prevents the birds infringement.
