Technical field
The utility model relates to electric power cable technical field, particularly the light-duty water-and fire-proof cable of a kind of aluminium alloy conductor.
Background technology
Current domestic fire-resisting cable adopts the wrapped fire-resistant isinglass belt of copper core conductor extruded insulation more substantially, fill and wrapped fire proofing, can realize cable to bear in certain fire process, again be energized as requested, cable still can work a period of time, but in fire process, inevitably act on cable from building collapsing or falling object, easily occur insulating barrier distortion or break, thus causing cable fault, after fire process terminates, cable cannot realize power supply capacity; In fire process, inevitably cause water in pipe burst or fire extinguishing procedure to enter cable insulation and conductor, thus cause cable cisco unity malfunction; And traditional fire-resisting cable is in vertical run process, because cable deadweight is too high, can not greater depth lay.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, there is provided a kind of aluminium alloy conductor light-duty water-and fire-proof cable, it adopts the light-duty waterproof material of aluminium alloy as conductive core material and adopts mica tape, Ceramic silicon rubber and wrinkle aluminium-alloy pipe as protection insulating barrier, can greater depth vertical run, have water-and fire-proof function, cost is lower.
For solving the problem, the utility model provides following technical scheme:
The light-duty water-and fire-proof cable of a kind of aluminium alloy conductor; comprise cable core and insulating coating; some cable cores are surrounded with in insulating coating; cable core is sequentially conductive core material, mica tape, Ceramic silicon rubber insulating barrier and insulating protective layer from the inside to the outside; conductive core material is that aluminum alloy material is made, and insulating protective layer is wrinkle aluminium-alloy pipe.
Wherein, insulating coating is sequentially Ceramic silicon rubber protective sleeve, tin plated steel wire braid and outer protective sleeve from the inside to the outside.
Further, between some cable cores, Ceramic silicon rubber packing is filled with in insulating coating.
Preferably, 4 cable cores are equidistantly laid with in insulating coating.The thickness of Ceramic silicon rubber insulating barrier is the 1/5-1/2 of conductive core material diameter.
Compared with prior art the beneficial effects of the utility model are:
1, aluminium alloy conductor self has good mechanical performance index, and weight is light-duty simultaneously, is more suitable for the vertical run of greater depth.Lighter than adopting the cable weight of copper conductor when needing same ampacity.
2, the insulating barrier of cable adopts mica tape, Ceramic silicon rubber, wrinkle aluminium-alloy pipe three-layer protection; wherein mutually be engaged with the aluminium-alloy pipe insulating protective layer of corrugated with the insulation of protruding Ceramic silicon rubber; in " point " contact condition; can be better heat insulation, guarantee that insulating barrier normally works under fire hazard environment
3, wrinkle aluminium-alloy pipe is sealed tube, aluminium-alloy pipe is lightweight, have better mechanical performance simultaneously, under fire hazard environment, even if the outer jacket of cable occurs damaged, aluminium-alloy pipe still can ensure when stamping out a fire, water can not immerse the insulating barrier of cable, guarantees that cable can normally work in the process of stamping out a fire.
4, center adopts preformed support to fill, all isolated in the middle of every root core, is more conducive to the spaced heat of core.
5, adopt after cable cabling Ceramic silicon rubber add Mica tape layer and tin plated steel wire braiding as sheath; cable is after burning; the Ceramic silicon rubber of internal layer forms hard protective case; under the constraint of mica tape and tin plated steel wire braid, even if stand the aluminium-alloy pipe protective layer that certain mechanical shock also can not damage cable insulation.
6, in cabling process, cable acts directly on the tin plated steel wire braid of cable through line card, the steel wire braid of cable can bear the pulling force of cable self, by the upper end of steel wire braid and interlude after reasonably fixing, even if in fire hazard environment, cable also there will not be and fixedly gets loose, and is more conducive to the safe operation of cable in fire hazard environment.
