The invention discloses a high-strength, high-flame retardant and fire-resistant optical cable. The optical cable comprises a cable core; the periphery of the cable core is coated with a water-resisting layer; the exterior of the water resisting layer is coated with a first sheath layer; the exterior of the first sheath layer is coated with a second sheath layer; the first sheath layer includes a steel-plastic composite belt and a ceramicizable polymer fireproof flame-retardant inner protective layer, wherein the steel-plastic composite belt longitudinally coats the water resisting layer; and the second sheath layer includes a steel wire armor and a high-flame retardant outer sheath, wherein the steel wire armor is arranged at the periphery of the ceramicizable polymer fireproof flame-retardant inner protective layer. According to the fire-resistant optical cable, the inner sheath and the outer sheath are combined advantageously, so that the fire-resistant optical cable has excellent mechanical properties such as tensile performance, compressive strength and impact in installation and use, and can withstand the burning of large flames as well as the spray of fire fighting water, the hit of heavy objects and the impact of falling objects in rescue; after a fire, the cable core can be still protected in a hard ceramic sleeve, and communication will not be interrupted; and thus communication loss caused by the fire can be reduced to the greatest extent.
Description
Technical field
The present invention relates to communication cable field, be specifically related to a kind of high-intensity high combustion flame-proof cable.
Background technology
Along with electric power and the development of communication technology, various optical cables occur the most therewith, but once breaking out of fire, in addition to personal safety and safety of property and loss of communications, the pollution problem of cable material also brings the biggest puzzlement, therefore, in recent years, improving the fire resistance of optical cable, the consciousness such as environmental protection cable material gradually strengthens.
Although existing frequently-used flame-proof cable has preferable fire resistance than ordinary optical cable, but under flame status or under the condition of high temperature of more than 500 DEG C, optical cable is licked by big fire can lick, and during along with the disaster relief, fire water spray, weight tap, cast impact, and the optical cable core of cable interior is destroyed, it is impossible to ensure that transmission performance is unimpeded, cause interruption, cause serious loss to communication in fire.Further, in tunnel, oil field, area that the muroid such as mine is rampant, flame-proof cable also suffers from the destruction that muroid bites.
Therefore, need now a kind of flame-proof cable, wish that optical cable has the design of good structure, material selects to make optical cable also to have external diameter feature little, lightweight and well mechanical performance and environmental performance in addition to having excellent transmission performance, propagation of flame not only will not be caused when running into fire, a large amount of poisonous and harmful smog will not be discharged, but also communication can be kept in a very long time constantly, for seeking survival and more time and chance are got in rescue.Also there is the function that certain anti-rodent bites when special occasions uses simultaneously.
Summary of the invention
It is an object of the invention to the problem above overcoming prior art to exist; a kind of high-intensity high combustion flame-proof cable is provided; have outside the cable core of flame-proof cable of the present invention composite steel-plastic belt+can porcelain macromolecule fire resistant flame retardant inner sheath, no matter there being perfect protection after making cable core before catching fire or catching fire；Wire armoring+LSZH environmental protection high fire-retardance oversheath provides higher comprcssive strength for optical cable again, increases optical cable and bears the ability that external force is destroyed, effectively prevents muroid from biting destruction.
Above-mentioned flame-proof cable inner/outer sheath advantageous combination makes this optical cable not only have the mechanical performances such as good tension, resistance to compression, shock resistance when laying and use；And when fire can with certain limit bear big fire lick lick, fire water spray in the disaster relief, weight percussion, cast impact etc. destroy；Communication will not be interrupted during cable core is still protected in hard ceramic jacket after fire, thus reduce the loss of communications that fire causes to greatest extent.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of high-intensity high combustion flame-proof cable, it includes cable core, described cable core is by some fiber units, center reinforcement, flame resistant filler rope forms, described cable core is circular configuration, described cable core periphery is coated with water blocking layer, ground floor sheath it is coated with outside described water blocking layer, it is coated with second layer sheath outside described ground floor sheath, described ground floor sheath includes composite steel-plastic belt and can porcelain macromolecule fire resistant flame retardant sheath, described composite steel-plastic belt is vertical to be wrapped in outside described water blocking layer, the protection set that formation is hard can be combined with described composite steel-plastic belt by porcelain macromolecule fire resistant flame retardant sheath described in when catching fire；Described second layer sheath includes wire armoring and high fire-retardance oversheath, described wire armoring be arranged on described can the periphery of porcelain macromolecule fire resistant flame retardant sheath, described high fire-retardance oversheath is the outermost layer jacket structure of optical cable.
In a preferred embodiment of the present invention, farther including, described fiber unit includes that some core fibres, described outer fiber are provided with Loose tube, is filled with dry type and blocks water implant in the space between described Loose tube and described optical fiber.
In a preferred embodiment of the present invention, farther including, some described fiber units and the described flame resistant filler rope with its equal diameters surround circle, and it is described center reinforcement that described fiber unit and described flame resistant filler rope enclose conglobate center.
In a preferred embodiment of the present invention, farther include, being additionally provided with material water-proof material, described material water-proof material is axially arranged, and described material water-proof material is arranged in the space between described center reinforcement and described fiber unit or described center reinforcement and described flame resistant filler rope.
In a preferred embodiment of the present invention, farther including, described water blocking layer is water-swellable tape, and described water-swellable tape is vertical to be wrapped or around wrapping in outside described cable core.
