Background technology
The flame-retardant optical cable of main application in the market, the fire resistance generally by selecting excellent flame-retardant sheath material to improve optical cable, but the non-flame resistant 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 because the destruction of external environment performance or mechanical stress causes optical fiber fragility fracture, thus can cause the interruption of signal transmission, have impact on the validity of safe-guard system to a great extent; On the other hand, even if optical cable core inside is not subject to the destruction of extraneous flame burn, but in the process that follow-up fray-out of flame cools gradually, optical cable surfacing causes at optical fiber surface adhesive stress due to the cooling meat of temperature after burning, thus affect distortion or the interruption of signal transmission, the use of phone, closed-circuit television, automatically-controlled door, alarm bell etc. will certainly be caused like this to break down, greatly can affect the emergency measures after fire generation.
Constantly universal along with 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 the place of these keys is very harsh to flame-retarding grade.Lightning protection flame-retardant optical cable, guarantee its do not become in fire prolong combustion instrument basis on, ensure light signal transmission fire occur and occur after a time period in unaffected, ensure communication smooth and easy.Traditional fire-retardant cable is generally made up of central reinforce member, the cable core of Loose tube structure, moisture-proof layer, inner sheath, armor, oversheath.Traditional optical cable, the general measure improving burning performance is the fire resistance strengthening protecting sleeve of optical cable.But owing to also there is sleeve pipe in optical cable, fine cream, the material of the non-flame resistant such as ointment, even if therefore adopt fire proofing costly, also optical cable high-performance refractory cannot be ensured, thus affect the utilization of optical cable in the higher occasion of some safe classes, and the oversheath extrusion process of optical cable is generally divided into fusing, cool and recrystallization, because the existence of amorphous state molecule can cause the problem of optical cable retraction after finished product comparatively serious, the oversheath extrusion process of optical cable is generally divided into fusing, cool 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 drawing thunder is high, for optical cable brings 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 cable core preferably not by fire threat, improve the shrinkage of cable jacket while playing drawing-resistant function well; Further, optical cable all dielectric, without metal ingredient, ensure that it is incorporated into indoor security outdoor, avoids the attack of thunder and lightning.
For achieving the above object, the technical solution of the utility model is as follows;
A kind of lightning protection flame-retardant optical 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 tube and is arranged on the multifiber in Loose tube, also fills fine cream in described Loose tube inside; described reinforcement has two, is parallelly embedded in oversheath.
According to above-mentioned lightning protection flame-retardant optical cable, wherein, described reinforcement is non-metal reinforcement member.
According to above-mentioned lightning protection flame-retardant optical cable, wherein, described ceramic fibre strip is arranged between waterstop and oversheath, and described Loose tube arranges waterstop.
Beneficial effect
The utility model ensure that the performance that fiber optic cable flame retardant is fire-resistant, improves the flame-retarding performance rate in applied environment; And adopt all dielectric structural design, there is obvious lightning protection effect, utilizing existing local telephone network pole line directly to lay to avoiding the accident rate drawing thunder during indoor, for optical cable brings facility in popularization is built; Ceramic fibre material is applied and has been started precedent on optical cable, also widened the thinking improving fiber optic cable flame retardant fire performance simultaneously, this material has good thermal insulation, thermal stability and chemical stability, and continuous serviceability temperature can reach 1000 DEG C, can ensure cable core preferably not by fire threat; The oversheath extrusion process of optical cable is generally divided into fusing, cools 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, improves the shrinkage of cable jacket while playing drawing-resistant function well; Further, optical cable all dielectric, without metal ingredient, ensure that it is incorporated into indoor security outdoor, avoids the attack of thunder and lightning.Optical cable adopts two nonmetallic reinforcements to provide pulling force.
