Description
Technical field
The present invention relates to field of cable technology, specially a kind of high temperature-resistant cable.
Background technology
Cable is in the development of the national economy, as transmitting electric power and propagate the carrier of information, serve huge effect, with the quickening of urbanization process, electric power transmission and the fast development of communication, so that requirement more and more higher of the people to electric wire, the characteristics of not requiring nothing more than cable there is safety and environmental protection, and with relatively low cost.
But the existing most heat-resisting ability of common insulated cable is poor, use requirement is not reached, supply line can not be kept to continue safely and steadly to run under flame condition, when there is fire, cable can ignition quickly, stop power supply, be unfavorable for the evacuation egress and fire rescue of personnel, for this, we devise a kind of high temperature-resistant cable, for solving the above problems.
The content of the invention
It is an object of the invention to provide a kind of high temperature-resistant cable, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of high temperature-resistant cable; including wire core; the wire core is wrapped with insulating barrier; the insulating barrier is wrapped with mica tape flame retardant coating, and packed layer is provided with the outside of mica tape flame retardant coating, and vacuum layer is provided with the outside of the packed layer; inner surface protective layer is provided with the outside of the vacuum layer; armor is provided with the outside of the inner surface protective layer, outer surface protective layer is provided with the outside of the armor, flame-retardant layer is provided with the outside of the outer surface protective layer.
Preferably, the inside of the packed layer is provided with reinforcement.
Preferably, the insulating barrier is rubber insulation or plastic insulating layer.
Preferably, the armor uses coppered steel wire, for strengthening conductor intensity and toughness.
Preferably, the flame-retardant layer is one layer of fine and close carbonized film.
Preferably, the outer surface protective layer uses perfluoroethylene-propylene material or low cigarette IXPE material with inner surface protective layer.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is provided with packed layer using mica tape flame retardant coating and insulating barrier parcel wire core, and packed layer is filled with reinforcement, the intensity of cable is strengthened, is less prone to and is pulled apart, armor and flame-retardant layer are also provided with outer layer, effectively improve the resistance to elevated temperatures of cable
The place higher to high temperature resistant requirement is can apply to, the present invention also has excellent wearability and mechanical strength, and the adaptability to severe use environment is stronger.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
In figure：1 flame-retardant layer, 2 outer surface protective layers, 3 armors, 4 inner surface protective layers, 5 vacuum layers, 6 packed layers, 7 mica tape flame retardant coatings, 8 insulating barriers, 9 wire cores.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Fig. 1 is referred to, the present invention provides a kind of technical scheme：A kind of high temperature-resistant cable,Including wire core 9,Wire core 9 is wrapped with insulating barrier 8,Insulating barrier 8 is rubber insulation or plastic insulating layer,Insulating barrier 8 is wrapped with mica tape flame retardant coating 7,The outside of mica tape flame retardant coating 7 is provided with packed layer 6,The inside of packed layer 6 is provided with reinforcement,Effectively improve the intensity of cable,The outside of packed layer 6 is provided with vacuum layer 5,For completely cutting off the external world,The outside of vacuum layer 5 is provided with inner surface protective layer 4,The outside of inner surface protective layer 4 is provided with armor 3,Armor 3 uses coppered steel wire,For strengthening conductor intensity and toughness,It is not easy to break or breaks down,The outside of armor 3 is provided with outer surface protective layer 2,Outer surface protective layer 2 uses perfluoroethylene-propylene material or low cigarette IXPE material with inner surface protective layer 4,Effectively protect armor 3,The outside of outer surface protective layer 2 is provided with flame-retardant layer 1,Flame-retardant layer 1 is one layer of fine and close carbonized film,For preventing fire damage power cable equipment.
The above; preferably specific embodiment only of the invention; but protection scope of the present invention is not limited thereto; any one skilled in the art the invention discloses technical scope in; technology according to the present invention scheme and its improvement design are subject to equivalent or change, should all cover within the scope of the present invention.
