Abstract
The present invention discloses a kind of fire-resisting cable, comprise oversheath, oversheath clad metal twining package tape, the coated flame retardant coating of metal twining package tape, holds at least two group cores in flame retardant coating, isolated by inner sheath between two adjacent groups core, isolated by inner sheath between core and flame retardant coating, inject foam fire-fighting material in inner sheath, in flame retardant coating internal clearance, fill inorganic refractory expanding material, described core comprises insulating barrier, insulating barrier coating conductor layer.The present invention proposes a kind of fire-resisting cable, not only can prevent fire from occurring, and, after fire occurs, can also fire spread be prevented.
Description
Technical field
The present invention relates to a kind of fire-resisting cable.
Background technology
Cable carries out the most frequently used carrier of electric power transfer, cable in actual use, because the conductor part of cable exists resistance, easy accumulated heat, when accumulation of heat to a certain extent after, easily cause fire, urgently improve.
Summary of the invention
For solving in background technology the technical problem existed, the present invention proposes a kind of fire-resisting cable, not only can fire preventing, and, after fire occurs, can autonomous the spreading of fire preventing.
A kind of fire-resisting cable that the present invention proposes, comprise oversheath, oversheath clad metal twining package tape, the coated flame retardant coating of metal twining package tape, holds at least two group cores in flame retardant coating, isolated by inner sheath between two adjacent groups core, isolated by inner sheath between core and flame retardant coating, inject foam fire-fighting material in inner sheath, in flame retardant coating internal clearance, fill inorganic refractory expanding 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 siliceous 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 fire-resisting cable that the present invention proposes, when cable internal conductor layer is overheated and after the insulating barrier that ignites, if the inner sheath contacted with insulating barrier is ignited equally, then the foam fire-fighting material in it overflows, and will play extinguishing effect, fire spread can also be stoped, meanwhile, the inorganic refractory expanding material heat of filling in flame retardant coating internal clearance expands, and can extrude inner space further, make inner without combustion medium, thus prevent fire spread.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of fire-resisting cable that the present invention proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of fire-resisting cable that the present invention proposes.
With reference to Fig. 1, a kind of fire-resisting cable that the present invention proposes, comprise oversheath 6, oversheath 6 clad metal twining package tape 5, the coated flame retardant coating of metal twining package tape 5, at least two group cores are held in flame retardant coating, isolated by inner sheath 7 between two adjacent groups core, isolated by inner sheath 7 between core and flame retardant coating, foam fire-fighting material 8 is injected in inner sheath 7, when cable is overheated and after there is spontaneous combustion due to conductor layer 1, first, insulating barrier 2 can be caused to burn, the Contact of insulating barrier 2 outer wall and inner sheath 7, insulating barrier 2 will ignite inner sheath 7, after inner sheath 7 is ignited, in it, foam fire-fighting material 8 overflows, extinguishing effect will be played, simultaneously, fire spread can also be stoped, simultaneously, inorganic refractory expanding material 3 heat of filling in flame retardant coating internal clearance expands, inner space can be extruded further, make inner without combustion medium, thus prevent fire spread, core comprises insulating barrier 2, insulating barrier 2 coating conductor layer 1.Flame retardant coating is made up of the refractory fibre braid 9 of silica compound layer 4 and coated siliceous 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; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
