Abstract
The present invention relates to a kind of all dielectric self-supporting protection against rodents leading in cable, including oversheath and optical communication element, it is characterized in that the nonmetallic protection against rodents reinforcer of 3 circular cross-sections is coated with oversheath, the nonmetallic protection against rodents reinforcer of 3 circular cross-sections is laid around the cable heart, center cavity is formed, optical communication element is laid with center cavity.The present invention places the nonmetallic protection against rodents reinforcer of three circles in cable jacket, optical communication element is positioned in the center cavity that three circular non-metal reinforcement members surround, because nonmetallic protection against rodents reinforcer is GFRP protection against rodents reinforcers, surface is firm smooth, therefore optical cable is possessed very strong mouse bite preventing, anti-unfirmly closing performance；Non-metal reinforcement member possesses very strong tensile capacity and anti-collapse ability, and the self-supporting that can effectively improve optical cable makes somebody a mere figurehead performance；This cable configuration is simple and be all dielectric structure, can be with anti-lightning strike, and it is easy to open cable, is easy to construct and uses.
Description
Technical field
The present invention relates to a kind of all dielectric self-supporting protection against rodents leading in cable for technical field of photo communication.
Background technology
Along with the development of optical communication technique, the construction and FTTx networkings of 5G networks are being promoted, during this
Leading in cable uses extensive.Existing leading in cable is mostly introduced using common self-bearing type butterfly optical cable into corridor, a part
Can be exposed in outdoor, butterfly optical cable often uses steel wire to make somebody a mere figurehead to exist when using and draw outdoor thunder and lightning as self-bearing type tensile elements
Enter the potential safety hazard of interior, and the optical cable self-supporting span is usually no more than 30m, brings inconvenience to the bridging between building, together
When the phenomenon that optical cable is stung by mouse damage often easily occurs in some regions, directly affect the stability that user uses broadband network,
Add optical-fiber network maintenance cost.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of all dielectric for above-mentioned the shortcomings of the prior art
Self-bearing type protection against rodents leading in cable, the optical cable is not only anti-lightning strike, anti-damaged by rats performance is good and simple in construction, and self-supporting performance is high, is easy to
Construction and use.
The present invention is to solve the problems, such as that used technical scheme set forth above is：Including oversheath and optical communication element,
It is characterized in that being coated with the nonmetallic protection against rodents reinforcer of 3 circular cross-sections in oversheath, 3 nonmetallic protections against rodents of circular cross-section add
Strong part is laid around the cable heart, forms center cavity, optical communication element is laid with center cavity.
By such scheme, the nonmetallic protection against rodents reinforcer of described circular cross-section is GFRP protection against rodents reinforcers, the firm light in surface
It is sliding.
By such scheme, the mutually tangent close connection of described 3 nonmetallic protection against rodents reinforcers of circular cross-section, 3 are formed
The mutually circumscribed center cavity of camber line.
By such scheme, a diameter of 0.8mm ~ 8.0mm of the nonmetallic protection against rodents reinforcer of described circular cross-section, it is usually
1.5mm~5.0mm。
By such scheme, the diameter of described 3 nonmetallic protection against rodents reinforcers of circular cross-section is identical.
By such scheme, the stranded mode that described 3 nonmetallic protection against rodents reinforcers of circular cross-section are twisted with SZ or S is twisted is installed
In oversheath, twisting pitch is 100 ~ 500mm.
By such scheme, water-blocking component is filled with described center cavity.
By such scheme, the fiber unit can be the one or more in optical fiber, fibre bundle or tight tube fiber.
By such scheme, water-blocking component is filled with the outside of the nonmetallic protection against rodents reinforcer the tangent of 3 circular cross-sections.
By such scheme, described water-blocking component is water blocking yarn or/and water-proofing powder etc..
The beneficial effects of the present invention are：1st, by placing the nonmetallic protection against rodents reinforcer of three circles in cable jacket,
Optical communication element is positioned in the center cavity that three circular non-metal reinforcement members surround, because nonmetallic protection against rodents reinforcer is
GFRP protection against rodents reinforcers, surface is firm smooth, therefore optical cable is possessed very strong mouse bite preventing, anti-unfirmly closing performance；2nd, it is nonmetallic to add
Strong part possesses very strong tensile capacity and anti-collapse ability, and the self-supporting that can effectively improve optical cable makes somebody a mere figurehead performance, suitable for self-bearing type
Introduce purposes；3rd, cable type is dry type, and water blocking yarn or water-proofing powder are filled with internal clearance, is filled without ointment, is advantageous to mitigate
Optical cable weight, also allow for construction and continue, it is free from environmental pollution；4th, the present invention is all dielectric structure, can utilize existing electric power bar
Tower is laid, and saves expense and construction period, and can be with anti-lightning strike；5th, the present invention is simple in construction, directly can be cut out using cutter
Oversheath, the light unit in center will not be hurt, be easy to construct and use.
