Description
Technical field
The utility model relates to a kind of flame-proof cable, and particularly a kind of stainless steel cast armouring flame-proof cable belongs to the technical field of optical fiber communication, supervision and control system.
Background technology
The space situations of relative closures such as railway tunnel, subway, track traffic, skyscraper, oil depot, mine; More and more wider application optical fiber cable is made optical fiber communication, supervision and the control system of transmission line; Fire fighting monitoring system particularly, the optical cable that fire takes place to adopt the back can very fast burn injury, causes the optical fiber cable system for transmitting to lose efficacy; For this reason, flame-proof cable begins to be applied to this type systematic.Existing fire-resisting cable, light unit are for one type to adopt PBT (polybutylene terephthalate fiber) to make light cell protection layer, and another kind of is that stainless-steel tube is made light cell protection layer, includes optical fiber or fibre ribbon, fine cream, or includes tightly packaged fiber; Usually the mode that adopts is; Outside the light unit, take to be provided with inner sheath, mica tape or the glass fibre belt refractory insulating layer of halogen-free and low-smoke flame-retardant polyolefin, vertical wrapping line composite steel-plastic belt; The oversheath of halogen-free and low-smoke flame-retardant polyolefin; Carry parallel steel wire in the oversheath secretly and a FRP (fibre-reinforced plastics) or steel wire are set as reinforcement, and absorb the characteristic of heat when utilizing the halogen-free and low-smoke flame-retardant polyolefin pyrolytic, to obtain good fire prevention and flame retardant effect as reinforcement or center.But, make the optical cable of light cell protection layer to adopt PBT, because of only about 230 ℃ of PBT fusing point; Outside at optical cable through 50 ℃ of burnings of 750 ℃ of scholars 90 minutes; Often because of heat imports inner structure into, cause the distortion of PBT pipe or damage light unit and optical fiber, combustion process or combustion are in finishing the back cooling procedure; Internal material produces distortion, causes optical fiber damage or destruction; Equally, make light cell protection layer with stainless-steel tube, stainless-steel tube can be because of burning distortion, but the not good optical cable of fire insulation, effect of heat insulation still can be because of the heat conduction of long-time burning, still can make the inner optical fiber damage of optical cable or destroys, and finally causes optical fiber communication to be lost efficacy.In addition, under narrow space, environmental baseline with a varied topography, carry out cable laying operation and when using, the tension of existing flame-proof cable, measuring body performance are also not enough, the phenomenon of optical cable damage often occurs.
The utility model content
The purpose of the utility model is: overcome the problem that exists in the prior art, provide that a kind of intensity is high, fire-resistant, tension and the good stainless steel cast armouring flame-proof cable of compressive property.
In order to achieve the above object, the technical scheme of the utility model employing is:
A kind of stainless steel cast armouring flame-proof cable; Bag is carried out successively from inside to outside; Comprise stainless steel tube optical unit, anti-deformation thermofin, refractory insulating layer, inner sheath, wire armoring, steel-tape armouring, oversheath, it is characterized in that: said stainless steel tube optical unit is that bag is carried out one or more optical fiber and inhaled the fine cream of hydrogen in the stainless-steel tube;
Said anti-deformation thermofin is an elastic body, and this elastic body is the rubber-plastic elastomer of low smoke, zero halogen;
Said refractory insulating layer is fire-resistant isinglass belt or glass fiber tape, or the combination of fire-resistant isinglass belt and glass fiber tape;
Said inner sheath and said oversheath are extrude halogen-free and low-smoke flame-retardant polyolefin sheathed;
To be one deck or two layers of steel wire closely be arranged in the inner sheath outside with the mode of spiral to said wire armoring, and used steel wire is zinc-coated wire or tin plated steel wire or phosphatization steel wire;
Said steel-tape armouring is corrugated steel tube or ripple steel plastic band, and corrugated steel tube is that steel band is carried out moulding through horizontal bundle ripple, bag, and the longitudinal seam continuous welding forms; The ripple steel plastic band is that steel plastic band is carried out moulding through horizontal bundle line, bag, and vertically steel plastic band is overlapped and formed.
The utility model has been obtained following beneficial effect with respect to prior art:
Through fire insulation, heat insulation and burning front and back minimizing deformed configurations and function are set in flame-proof cable; Reduced on the one hand that heat is transmitted to the light unit in long-time combustion process; Having reduced the light unit is on the other hand burning and is receiving thermal process, heating to finish structure and distortion of materials and variation in the temperature-fall period; Reached the technique effect that keeps optical fiber communication, made flame-proof cable have good optics, fire-resistant and fire-retardant characteristic; Such cable configuration is simple, manufacturing cost is lower, and the structure of steel wire and steel band double armor not only improves fire-resistance property, and has good tension and compressive property, and reliability improves greatly when cable laying operation and use; Simultaneously, adopted the material of low smoke, zero halogen, fire-retardant and environmental protection, reduced when fire takes place influence, produced good society and economic resultant effect the safety of environment, the person and facility.
