The insulaion resistance of edge, causes cable unqualified, is taken in some producers of above reason and to extrude layer of polyethylene material, this
Although method solves two problems of the above, but there are problems that；1st, roundness bad control when fireprotection layer is extruded,
2nd, fireprotection layer uneven distribution is even or even subregion occur does not have fireprotection layer to cause fire protecting performance unqualified.
Utility model content
The purpose of this utility model is to overcome the defect of prior art to ensure cable fire-proof performance and cable there is provided one kind
The fireprotection layer of roundness.
To achieve these goals, the technical scheme that the utility model is taken is as follows：
A kind of fireproof cable, it includes the conductive core of more than one and is successively set on compound on the outside of the conductive core
Insulating barrier, screen layer, anti-corrosion separation layer, fireprotection layer, halogen-free flameproof layer, Halogen restrictive coating, the anti-corrosion separation layer are outer vertically
It is provided with cut-off tooth week.
Further, the conductive core includes conductor and parcel is arranged on the mineral compound inslation of the conductor outer layer
Layer.
Further, the composite insulation layer is cross-linked polyethylene layer.
Further, the screen layer is aluminum metal layer.
Further, the ceramic silastic-layer of the anti-corrosion separation layer.
Further, the fireprotection layer is inorganic mineral insulation layer.
Further, the halogen-free flameproof layer is mica layer.
Further, the Halogen restrictive coating is low smoke halogen-free flame-retardant polyolefin external sheath layer.
Compared with prior art, having the beneficial effect that acquired by the utility model：
The utility model is by setting anti-corrosion separation layer to play the anti-corrosion of metal level and preventing the effect into water, and by setting
It is uniformly to ensure cable fire-proof performance and guarantee cable roundness to ensure that fireprotection layer extrudes thickness to put cut-off tooth.

Embodiment
Further details of narration is carried out to the utility model below in conjunction with accompanying drawing.
A kind of fireproof cable, it includes the conductive core of more than one and is successively set on compound on the outside of the conductive core
Insulating barrier 2, screen layer 3, anti-corrosion separation layer 4, fireprotection layer 5, halogen-free flameproof layer 6, Halogen restrictive coating 7, the edge of anti-corrosion separation layer 4
Axial periphery is provided with cut-off tooth 1, and the conductive core includes conductor 1-1 and parcel is arranged on the ore deposit of the conductor 1-1 outer layers
Thing composite insulation layer 1-2, the composite insulation layer 2 is cross-linked polyethylene layer, and insulating barrier is made using crosslinked polyethylene, and crosslinking is poly-
Ethene insulation is, using chemically or physically, cable insulation polyethylene molecule is changed into main body by linearity molecular structure
Network molecular structure, i.e., thermoplastic polyethylene is changed into heat cured crosslinked polyethylene, so as to greatly improve its heat resistance
And mechanical performance, its shrinkage is reduced, not re-melting, and maintain excellent electric property after making it heated.Therefore,
It is crosslinked polyetylene insulated that there is good superiority in heat-resisting, mechanical properties, so that insulating barrier has heat resistance and Nai Qie
The performance such as cut.The screen layer 3 is aluminum metal layer, and aluminum metal layer has shielded signal and improves the effect of cable intensity, described
Anti-corrosion separation layer 4 is ceramic silastic-layer, extrudes to form inner liner by mineral ceramic powder and silicon rubber, is so running into fire
When, inner liner can form ceramic shell, so that the heat transfer produced when preventing flame combustion is to internal cable core, so that
Avoid cable core from damaging, while inner liner can also prevent erosion of the moisture produced during fire extinguishing to cable core, play isolation and make
With the fireprotection layer 5 is inorganic mineral insulation layer, and the halogen-free flameproof layer 6 is mica layer, and the fire resisting that mica layer is used as cable is exhausted
Edge layer, to ensure that cable can be continued to run with the certain time after catching fire, the Halogen restrictive coating 7 is poly- for low-smoke non-halogen flame-retardant
Alkene external sheath layer, cable outermost sets low smoke halogen-free flame-retardant polyolefin external sheath layer when occurring fire dangerous situation, and burning can
To form porous carbon shell, so as to play heat-blocking action, periphery is provided with cut-off tooth 1 to the anti-corrosion separation layer 4 vertically, described
Conductive core includes conductor 1-1 and parcel is arranged on the mineral composite insulation layer 1-2 of the conductor 1-1 outer layers, anti-by setting
The fire resistance characteristic of rotten separation layer play the anti-corrosion of metal level and prevent insulation intake effect, and by set cut-off tooth be in order to
Ensure that fireprotection layer extrudes thickness and uniformly ensures cable fire-proof performance and ensure cable roundness.
Manufacturing process is as follows：
The utility model is to be extruded material using particular manufacturing craft with conventional extruder in many of fireproof cable or single to prevent
A kind of toothed anti-corrosion separation layer outside thermoelectricity cable metal level, is to play the anti-corrosion of metal level using its fire resistance characteristic and prevent absolutely
The effect of edge water inlet, band tooth is uniformly to ensure cable fire-proof performance and guarantee cable rounding to ensure that fireprotection layer extrudes thickness.
Embodiment described above is only preferred embodiment of the present utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, on the premise of without departing substantially from the utility model principle and spirit, it is made
Any obvious change gone out, should all be contemplated as falling with claims of the present utility model.
