Abstract
The utility model relates to an all-dielectric self-supporting rodent-resistant optical cable which is used in the field of optical communication. The optical cable comprises a cable core and an external protective layer; an all-dielectric reinforcing layer is arranged outside the cable core; a nonmetallic armored rodent-resistant layer is covered outside the all-dielectric reinforcing layer; and the external protective layer is arranged outside the nonmetallic armored rodent-resistant layer. The optical cable provided by the utility model has the beneficial effects that 1, the nonmetallic armored layer is adopted to perform physical rodent control, no chemical agent is used, the optical cable is environment friendly and can effectively protect the cable from being bitten by squirrels; 2, the optical cable is conveniently aerially laid in forests and foothills in a self-supporting way where the terrain is more complex and the optical cable cannot be pipelined or directly buried; 3, the optical cable is in an all-dielectric structure, no induction current is produced; and the optical cable can be laid by the existing power tower, thus, the construction cost and period are saved and the optical cable can resist lightning strike; 4, the optical cable can be directly buried, and further can play a role of rodent resistance; and 5, the optical cable is simple in structure and good in technology.
Description
Technical field
The utility model relates to a kind of all dielectric self-supporting rodent-resistant cable that is used for optical communication field.
Background technology
In forest and knob use optical cable, for easy construction, can use aerial optical cables in a large number, yet because these areas often have squirrel to haunt, so usually can run into optical cable is stung damage by squirrel accident.Existing self-support aerial cable does not mostly possess the function that locking damaged by rats is decreased, in case optical cable is bitten broken causing communication disruption by squirrel, brings very big trouble for the operation and the maintenance of communication line.For addressing the above problem, occurred adopting the metal tape armour optical cable to carry out protection against rodents, but there is following deficiency in this structure: 1, owing to having the hardware existence not utilize in the optical cable and, causing executive cost and cycle to increase near the existing power shaft tower.2, the optical cable deadweight of use hardware armouring is bigger, is not easy to construction and maintenance, and is not suitable for the built on stilts use of self-bearing type.3, in the hylaea area, thunderbolt is frequent, uses built on stilts use of optical cable of metal tape armour to have bigger potential safety hazard.
Summary of the invention
The utility model technical matters to be solved is the deficiency that exists to above-mentioned prior art and a kind of all dielectric self-supporting rodent-resistant cable is provided; It not only possesses good mouse bite preventing and decreases function, and simple in structure, from heavy and light; Be convenient to self-bearing type and make somebody a mere figurehead and lay, and can anti-inductance and anti-thunderbolt.
The present invention for the technical scheme that problem adopted of the above-mentioned proposition of solution is:
Comprise cable core and outer jacket, it is characterized in that outside cable core, being provided with full medium enhancement Layer, full medium enhancement Layer coats non-metallic sheath protection against rodents layer outward, and non-metallic sheath protection against rodents layer coats outer jacket outward.
Press such scheme, between cable core and non-metal reinforced layer, can be provided with inner restrictive coating.
Press such scheme, between full medium enhancement Layer and non-metallic sheath protection against rodents layer, can be provided with middle restrictive coating.
Press such scheme, described cable core is layer-stranded optical cable core or central beam tube type optical cable core.
Press such scheme, described layer-stranded optical cable core comprises central reinforce member and centers on the mutually stranded loose sleeve pipe of central reinforce member, comprises fiber unit in the loose sleeve pipe; Layer-stranded optical cable core also can comprise the gasket for packing mutually stranded together with loose sleeve pipe.
Press such scheme, include water-blocking component in the described cable core.
Press such scheme, described non-metallic sheath protection against rodents layer is made up of in nonmetal wire, nonmetal band, non-metal rope, the nonmetal bar one or more.
Press such scheme, described full medium enhancement Layer is made up of in aramid yarn, glass fiber yarn, aramid belt, the glass fiber tape one or more.
The beneficial effect of the utility model is: 1, adopt non-metallic armoring layer to carry out the physics protection against rodents, do not use chemical agent, environmental friendliness can effectively be protected biting of squirrel; 2, can be convenient to that self-bearing type is built on stilts to be laid in forest and the hilly country that landform more complicated and optical cable are not easy to pipeline and directly buried installation; 3, this optical cable is full dielectric structure, can not produce induction current, and existing power shaft tower capable of using lays, and saves executive cost and cycle, and can prevent thunderbolt; 4, this optical cable also can be used for direct-burried, can play the protection against rodents effect equally; 5, the utility model is simple in structure, good manufacturability.
