Abstract
The invention discloses a refractory cable which comprises an outer sheath, wherein the outer sheath is wrapped on a metal warping tape which is wrapped on a refractory layer, at least two groups of wire cores are contained in the refractory layer, two adjacent groups of wire cores are separated by inner sheaths, the wire cores and the refractory layer are separated by inner sheaths, the inner sheaths are filled with a foam extinguish material, gaps in the refractory layer are filled with a inorganic refractory expansion material, and each wire core comprises an insulated layer which is wrapped on a conductor layer. The refractory cable disclosed by the invention not only can prevent the occuring of fire, but also can prevent the spreading of the fire when the fire breaks out.
Description
Technical field
The present invention relates to a kind of fire-resisting cable.
Background technology
Cable is to carry out the most frequently used carrier of electric power transfer, cable in actual use, because the conductor part of cable exists resistance, easily accumulated heat, when accumulation of heat to a certain extent after, easily cause fire, urgently improve.
Summary of the invention
For solving the technical problem existing in background technology, the present invention proposes a kind of fire-resisting cable, not only can fire preventing, and, after fire occurs, independently spreading of fire preventing.
A kind of fire-resisting cable that the present invention proposes, comprise oversheath, oversheath clad metal twining package tape, metal twining package tape is coated flame retardant coating, holds at least two group cores in flame retardant coating, between two adjacent groups core, isolated by inner sheath, between core and flame retardant coating, isolated by inner sheath, in inner sheath, inject foam fire-fighting material, in flame retardant coating internal clearance, fill inorganic refractory swelling material, described core comprises insulating barrier, insulating barrier coating conductor layer.
Preferably, flame retardant coating is made up of the refractory fibre braid of silica compound layer and coated Si materialization compound layer.
Preferably, silica compound layer adopts earth silicon material to make.
Preferably, metal twining package tape adopts that aluminium strip is wrapped forms.
In the present invention that the present invention proposes, when cable internal conductor layer overheated and ignite after insulating barrier, if with same being ignited of inner sheath of insulating barrier contact, the foam fire-fighting material in it overflows, and will play fire extinguishing effect, can also stop fire spread, meanwhile, the inorganic refractory swelling material heat of filling in flame retardant coating internal clearance expands, further extruding inner space, make inside without combustion medium, thereby prevent fire spread.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of fire-resisting cable of proposing of the present invention.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of fire-resisting cable of proposing of the present invention.
With reference to Fig. 1, the present invention proposes a kind of fire-resisting cable that the present invention proposes, comprise oversheath 6, oversheath 6 clad metal twining package tapes 5, the coated flame retardant coating of metal twining package tape 5, in flame retardant coating, hold at least two group cores, between two adjacent groups core, isolated by inner sheath 7, between core and flame retardant coating, isolated by inner sheath 7, the interior injection foam fire-fighting of inner sheath 7 material 8, after there is spontaneous combustion because conductor layer 1 is overheated in cable, first, can cause insulating barrier 2 to burn, between insulating barrier 2 outer walls and inner sheath 7, contact, insulating barrier 2 inner sheath 7 that will ignite, after inner sheath 7 is ignited, its inner foam extinguish material 8 overflows, to play fire extinguishing effect, simultaneously, can also stop fire spread, simultaneously, inorganic refractory swelling material 3 heats of filling in flame retardant coating internal clearance expand, further extruding inner space, make inner without combustion medium, thereby prevent fire spread, core comprises insulating barrier 2, insulating barrier 2 coating conductor layers 1.Flame retardant coating is made up of the refractory fibre braid 9 of silica compound layer 4 and coated Si materialization compound layer 4.Silica compound layer 4 adopts earth silicon material to make.Metal twining package tape 5 adopts that aluminium strip is wrapped to be formed.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
