Background technology
The flame-retardant optical cable of main application in the market, generally by selecting excellent flame-retardant sheath material to improve the fire resistance of optical cable, but the non-flame-retardant materials such as optical cable middle sleeve, fine cream, ointment also can affect the flame retardant level of whole optical cable.After fire occurs, traditional optical cable can cause optical fiber fragility fracture because of the destruction of external environment performance or mechanical stress, thereby causes the interruption of signal transmission, has affected to a great extent the validity of safe-guard system; On the other hand, even if optical cable core inside is not subject to the destruction of extraneous flame burn, but in follow-up fray-out of flame gradually in cooling process, optical cable surfacing is because the cooling contraction of the rear temperature of burning causes at optical fiber surface adhesive stress, thereby affect distortion or the interruption of signal transmission, will certainly cause like this use of phone, closed-circuit television, automatically-controlled door, alarm bell etc. to be broken down, can greatly affect the emergency measures after fire occurs.
Along with constantly popularizing of broadband network, optical cable has been widely used in the place of public place (as hospital, cinema, arenas etc.), subway, oil and other industry, and these crucial places are very harsh to flame-retarding grade.High-performance refractory flame-proof cable, guaranteeing that it prolongs on the basis of combustion instrument in not becoming fire, unaffected in the time period of the transmission of guarantee light signal after fire occurs and occurs, ensure that communication is smooth and easy.Traditional fire-retardant cable is generally made up of cable core, moisture-proof layer, inner sheath, armor, the oversheath of central reinforce member, loose sleeve structure.Traditional optical cable, the general measure that improves burning performance is the fire resistance that strengthens protecting sleeve of optical cable.But owing to also existing sleeve pipe in optical cable, fine cream, the non-fire-retardant material such as ointment, even if therefore adopt comparatively expensive fire proofing, also cannot ensure optical cable high-performance refractory, thereby affect the utilization of optical cable in the higher occasion of some safe classes, and the oversheath of optical cable extrudes process and is generally divided into fusing, cooling and recrystallization, because the existence of amorphous state molecule can cause the problem of optical cable retraction after finished product comparatively serious, the oversheath of optical cable extrudes process and is generally divided into fusing, cooling and recrystallization, because the existence of amorphous state molecule can cause the problem of optical cable retraction after finished product comparatively serious, the accident rate that draws thunder is high, for optical cable has brought inconvenience in popularization is built.
Utility model content
For overcoming the deficiency in prior art, the purpose of this utility model provides a kind of lightning protection flame-retardant optical cable, can ensure preferably that cable core is not subject to fire threat, has improved well the shrinkage of cable jacket in playing drawing-resistant function; And the full medium of optical cable is without metal ingredient, ensure that it is incorporated into indoor security from outdoor, has avoided the attack of thunder and lightning.
For achieving the above object, the technical solution of the utility model is as follows;
A kind of high-performance refractory flame-proof cable; it is characterized in that; comprise cable core, reinforcement and protective seam, protective seam is coated on the outside of cable core and reinforcement, wherein; described protective seam is made up of waterstop, ceramic fibre strip and oversheath; oversheath is the outermost layer of protective seam, and described cable core comprises loose sleeve pipe and is arranged on the multifiber in loose sleeve pipe, also fills fine cream at described loose inside pipe casing; described reinforcement has two, parallel being embedded in oversheath.
According to above-mentioned high-performance refractory flame-proof cable, wherein, described reinforcement is non-metal reinforcement member.
According to above-mentioned high-performance refractory flame-proof cable, wherein, described ceramic fibre strip is arranged between waterstop and oversheath, and described loose sleeve pipe arranges waterstop.
Beneficial effect
The utility model has ensured the performance of optical cable flame-retardant, has improved the flame-retarding performance rate in applied environment; And adopt the design of full dielectric structure, there is obvious lightning protection effect, utilizing existing local telephone network pole line directly to lay the accident rate of having avoided drawing thunder when indoor, for optical cable has brought facility promoting in building; Ceramic fibre material is applied and has been started precedent on optical cable, also widened the thinking of improving optical cable flame-retardant performance simultaneously, this material has good thermal insulation, thermal stability and chemical stability, and serviceability temperature can reach 1000 DEG C continuously, can ensure preferably that cable core is not subject to fire threat; The oversheath of optical cable extrudes process and is generally divided into fusing, cooling and recrystallization, because the existence of amorphous state molecule can cause the problem of optical cable retraction after finished product comparatively serious, the utility model is embedded in two parallel non-metal reinforcement members at sheath, has improved well the shrinkage of cable jacket in playing drawing-resistant function; And the full medium of optical cable is without metal ingredient, ensure that it is incorporated into indoor security from outdoor, has avoided the attack of thunder and lightning.Optical cable adopts two nonmetallic reinforcements that pulling force is provided.
