Abstract
The utility model relates to a kind of flame retardant cable.Mainly solve the problem that existing flame retardant cable exists intensity difference and poor fire.Comprise some conductors and sheath, sheath is positioned at the outermost layer of conductor, insulating barrier is equipped with outside each described conductor, ellipse is provided with and the flame-retardant layer vertically placed of its long axis direction between described insulating barrier and sheath, described sheath is the ellipse of long axis direction horizontal positioned, and the inwall of described sheath short-axis direction contacts with the outer end of flame-retardant layer long axis direction, forms space between the outside of described flame-retardant layer and the inwall of sheath, is filled with mica fire-retardant filler in described space.Sample between oval sheath and flame-retardant layer due to this flame retardant cable and form active force, and also there is fire-retardant filler, both ensure that the intensity of cable, further improved anti-flammability again, the effective useful life extending product.
Description
Technical field
The utility model relates to a kind of cable, refers in particular to a kind of flame retardant cable.
Background technology
Flame retardant cable, is likely burned in case of fire and can not runs, but can stop spreading of the intensity of a fire.Generally, electric wire, just in case catch fire, can be limited in subrange burning, not produce and spread, keep other various equipment, avoid resulting in greater loss.At present, although flame retardant cable anti-flammability can reach general requirement, its intensity is poor, in use yielding, affects its useful life.
Summary of the invention
In order to overcome deficiency in background technology and defect, the utility model provides a kind of flame retardant cable, solves the problem that existing flame retardant cable exists intensity difference and poor fire.
The technical solution of the utility model is: a kind of flame retardant cable, comprise some conductors and sheath, sheath is positioned at the outermost layer of conductor, insulating barrier is equipped with outside each described conductor, ellipse is provided with and the flame-retardant layer vertically placed of its long axis direction between described insulating barrier and sheath, described sheath is the ellipse of long axis direction horizontal positioned, and the inwall of described sheath short-axis direction contacts with the outer end of flame-retardant layer long axis direction, form space between the outside of described flame-retardant layer and the inwall of sheath, in described space, be filled with mica fire-retardant filler.
Described flame-retardant layer is steel band lapping layer.
Asbestos packing is provided with between described insulating barrier and flame-retardant layer.
Described insulating layer is haloflex layer.
Described conductor is 6, and wherein 4 vertically contact with the inwall of the long axis direction of flame-retardant layer in distribution, and other 2 are positioned at side direction and contact with the inwall of the short-axis direction of flame-retardant layer.
The beneficial effects of the utility model: sample between oval sheath and flame-retardant layer due to this flame retardant cable and form active force, and also there is fire-retardant filler, both ensure that the intensity of cable, further improved anti-flammability again, the effective useful life extending product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, conductor 1, sheath 2, insulating barrier 3, flame-retardant layer 4, space 5, mica fire-retardant filler 6, asbestos packing 7.
Embodiment
For accompanying drawing, embodiment of the present utility model is described further below:
As shown in the figure, a kind of flame retardant cable, comprise some conductors 1 and sheath 2, sheath 2 is positioned at the outermost layer of conductor 1, insulating barrier 3 is equipped with outside each described conductor 1, ellipse is provided with and the flame-retardant layer 4 vertically placed of its long axis direction between described insulating barrier 3 and sheath 2, described flame-retardant layer 4 is steel band lapping layer, described sheath 2 is the ellipse of long axis direction horizontal positioned, and the inwall of described sheath 2 short-axis direction contacts with the outer end of flame-retardant layer 4 long axis direction, space 5 is formed between the outside of described flame-retardant layer 4 and the inwall of sheath 2, mica fire-retardant filler 6 is filled with in described space 5.Sheath 2, flame-retardant layer 4 is ellipse, it is peripheral that sheath 2 is arranged on flame-retardant layer 4, sheath 2 horizontal positioned, flame-retardant layer 4 is vertically placed, mutually be in vertical distribution, sheath 2 is the structure for amplifying of flame-retardant layer 4, contacted with the outer wall of flame-retardant layer by the inwall of sheath 2, and be filled with filler in space, by the active force between sheath 2 and flame-retardant layer 4, effectively can prevent sheath, the distortion of flame-retardant layer, improve intensity, sample between oval sheath and flame-retardant layer due to this flame retardant cable and form active force, and also there is fire-retardant filler, both ensure that the intensity of cable, further improve anti-flammability again, the useful life of effective prolongation product.
As shown in the figure, in the utility model, between described insulating barrier 3 and flame-retardant layer 4, be provided with asbestos packing 7, improve anti-flammability.Described insulating barrier 3 is haloflex layer, good insulating, and described conductor 1 is 6, and wherein 4 vertically contact with the inwall of the long axis direction of flame-retardant layer 4 in distribution, and other 2 are positioned at side direction and contact with the inwall of the short-axis direction of flame-retardant layer 4.To sample above-mentioned distribution form, improve the stability of conductor distribution.
