Description
Technical field
The utility model belongs to field of cable technology, is specifically related to a kind of flexible fire-proof cable.
Background technology
Along with the development of society, the fire prevention of skyscraper, Important building is more and more by people are paid attention to, for improving fire safety grade, generally can adopt flame retardant cable, fire-resisting cable, aluminium sheath mineral insulated cable, the building high to fire protection requirement, as JinRong Building, major museum, large-scale theater etc. all can select fireproof cable.Flame retardant cable just adds fire retardant by insulating material and jacket material, so flame retardant cable insulating material used and sheath material itself or can burn, once breaking out of fire, so-called flame retardant cable still can light raging flames.Normal refractory cable has wrapped one deck fire-resistant isinglass belt on the conductor of cable, such cable still can be powered a period of time in the case of fire, very short during this period of time, but in case of emergency there is huge effect, and fire-resisting cable can puncture and loses transmission of electricity function afterwards.Existing fireproof cable structure adopts aluminium (copper) sheath mineral insulated cable, mainly extrude one deck circular aluminum protecting pipe outward at cable core, the inside extrudes mineral insulation, though this structure can play good flameproof effect, but the fireproof cable of this kind of structure is owing to adopting overall aluminum pipe or copper pipe and mineral insulation, cause Cable Bending Radius very large, to the structural requirement larger space of building, very inconvenient to the cable laying operation of cable, easily cause cable copper tube or aluminum pipe cracking, bring accident potential.
Utility model content
For the defect existed in prior art, the utility model provides a kind of flexible fire-proof cable, solves the problem of important place fireproofing of cable problem and cable laying construction inconvenience and easy cracking.
For reaching above object, the technical solution adopted in the utility model is: provide a kind of flexible fire-proof cable, comprise conductor, insulating barrier is arranged with outside described conductor, be arranged with packed layer outside described insulating barrier, outside described packed layer, be arranged with fire-resistant lapping layer, outside described fire-resistant lapping layer, be arranged with self-locking armour, be arranged with refuge floor outside described self-locking armour, the outer of described refuge floor is arranged with elastic body jacket layer.
Further, described refuge floor is the wrapped refuge floor of Ceramic silicon rubber band.
Further, described elastic body jacket layer is the elastic body jacket layer of high temperature resistant high flame retardant.
Further, described self-locking armour is the self-locking armour of aluminum alloy strip ripple.
Further, described insulating barrier is cross-linking radiation insulation polyolefin insulation layer.
Further, described packed layer is glass cord packed layer.
Further, described fire-resistant lapping layer is Ceramic silicon rubber band lapping layer.
Advantageous Effects of the present utility model is:
(1) the utility model improves with regard to fire protecting performance and cable bend performance two aspect, by being arranged with elastic body jacket layer outside refuge floor, make the bending property of cable more superior, when cabling, the radius of cable bend is little, and cable copper (aluminium) pipe can not be caused to ftracture;
(2) the utility model is by being provided with three layers of fire resistive construction, ensures that this cable is in the very high important place safe operation such as financial center, arenas, library of fire protection requirement grade.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model flexible fire-proof cable.
In figure:
The fire-resistant lapping layer of 1-conductor 2-insulating barrier 3-packed layer 4-
5-self-locking armour 6-refuge floor 7-elastic body jacket layer
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As shown in Figure 1, be the flexible fire-proof cable that the utility model provides, this cable comprises conductor 1, insulating barrier 2, packed layer 3, fire-resistant lapping layer 4, self-locking armour 5, refuge floor 6 and elastic body jacket layer 7 from inside to outside successively.
Wherein, insulating barrier 2 is irradiation crosslinked polyolefin insulating layer.It utilizes irradiation crosslinking processes, adopts low halogen-free anti-flaming polyolefin manufacture of materials, has high temperature resistant, high insulation, short-time overload capacity is strong, the life-span is long, wear-resisting, oil resistant, anticorrosion, pull resistance high advantage.
Packed layer 3 is glass cord packed layer.This packed layer is filled between the gap of many conductors, guarantees that cable has good roundness, can improve the fire-retardant rank of cable, the insulated wire cores relative position in cable is stablized, can increase the tensile strength of cable.
Fire-resistant lapping layer 4 is Ceramic silicon rubber band lapping layer.This lapping layer has fire prevention, fire-resistant and insulate effect, Ceramic silicon rubber is nontoxic at normal temperatures, tasteless, there is good flexibility and elasticity, can at 350 ~ 3000 DEG C, under the ablation time of more than flame 3min, organic principle in silicon rubber can the ablated housing changing into ceramic-like in a short period of time, instead of burnt till powdery ashes, the housing of this ceramic-like forms the hard protective layer of one deck, this protective layer stops burning away of flame, play the effect of isolated extraneous flame, thus protection is not damaged by the object burnt, the ablation time is longer, temperature is higher, housing is harder.
Self-locking armour 5 is self-locking aluminum alloy strip ripple armour.Armour this be easy to on-the-spot processing and fabricating, bending radius is little; Building interior wiring is very convenient, and lightly flexibly, anti-side pressure ability is strong, easily peels off; When indoor are laid, only need suspension bracket and strain relief clamp, without the need to using cable testing bridge or pallet, more without the need to adopting pipeline laying, fire-retardant rank is A level, and antiseptic property is excellent, can keep good metallic character under various acid or alkali environment.
Refuge floor 6 is Ceramic silicon rubber band refuge floor.Ceramic silicon rubber can completely cut off extraneous flame, thus protection is not damaged by the object burnt.
Elastic body jacket 7 is the elastic body jacket of high temperature resistant high flame retardant.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
