Abstract
The utility model provides a flexible fire-proof cable using mineral as base material for insulation and sheath, belonging to the technical field of the fire-proof cable. The flexible fire-proof cable is characterized in that an insulating layer and a sheath outside a conductor are mineral materials and are flexibly combined, the integral cable can be flexibly bent so as to be convenient to manufacture the cabe and reduce the producing cost, and the utility model can produce the length of the cable according to requirements, is also convenient for engineering to lay the cable and eliminates copper pipe joints. The utility model is able to bear the intense fire of 950 degrees and is able to safely supply power for three hours under the probability of being knocked or showered by water. The sheath is an orange mark.
Description
Technical field:
Belong to the fireproof cable technical field, exactly be a kind of be that base-material is done to insulate and the flexible fire-proof cable of sheath with mineral.
Background technology:
A kind of fireproof cable that uses is copper pipe mineral cables at present, and its center is single copper conductor, and skin is the copper pipe of using as sheath, make separator by magnesium oxide between the double layer of metal body, though simple in structure, need repeatedly annealing, drawing, labour intensity is big; Not only the single copper conductor at center has determined that the hardness of cable is very big, and outer field copper pipe also limited the factory length of cable, is difficult to satisfy user's needed length; This structure also causes lays that difficulty is big, joint hidden danger is many, and has increased construction cost and time.Copper pipe mineral cable also needs to increase special-purpose joint installation accessories.
At present, known anti-(anti-) thermoelectricity cable, but fire resistance period does not all surpass 90 minutes fire-protection rating, and the level of its proof voltage and heatproof degree also can't reach the standard of fireproof cable.
Summary of the invention:
The utility model is that a kind of refractory temperature height will be provided, and fire resistance period is long; Make the convenient a kind of flexible fire-proof cable of making insulation and sheath with mineral as base-material that uses easily.
Technical solution adopted in the utility model: wrapped successively by the mica mineral band with extrude the mineral insulation layer of handling by electron irradiation, formation sub-thread cable core by the skin of the stranded conductor that constitutes of copper cash bundle; Several sub-thread cable cores evenly distribute, the filling mineral flame material that goes out behind the stranded stranding, and wrapped or to extrude color be orange mineral composite sheath.
The mica mineral band is compressed on the glass fiber guipure by mica powder and constitutes.The mineral insulation layer is to serve as the mixing extrudate of the general inserts of main interpolation with aluminium hydroxide or magnesium hydroxide.
The mineral composite sheath is by aluminium-plastic tape or glass strap and aluminium hydroxide or magnesium hydroxide, adds inserts and binding agent and mixes to extrude and form.
After implementing the utility model, length electrogenesis in next life cable has saved the copper pipe joint connection on demand, can change the direction of lay on demand arbitrarily, and convenient construction is installed.
The utility model can bear 950 ℃ of big fire, may descending of bump or water pouring is being arranged, energy safe power supply 3 hours.
Description of drawings:
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Embodiment:
Now the utility model is described in further detail in conjunction with the accompanying drawings, the power cable manufacturing process is made flexible fire-proof cable routinely, constitute conductor 1 by the copper cash bundle is stranded, the wrapped successively mica mineral band 2 of its skin and extrude the mineral insulation layer of handling by electron irradiation 3, formation sub-thread cable core 4.Several sub-thread cable cores evenly distribute, the filling mineral flame material 5 that goes out behind the stranded stranding, and wrapped or to extrude color be orange mineral composite sheath 6.Mica mineral band 2 is to be compressed on the glass fiber guipure by mica powder to constitute; Mineral insulation layer 3 is based on aluminium hydroxide or magnesium hydroxide, adds the mixing extrudate of general inserts, and the mineral composite sheath is to add inserts and binding agent by aluminium-plastic tape or glass strap and aluminium hydroxide or magnesium hydroxide to mix to extrude and form.
