Description

A kind of flame retardant cable
Technical field
The present invention relates to a kind of electric power technical field of transportation, specially a kind of flame retardant cable.
Background technology
Supply of electric power is the guarantee that we live, but the disaster of some bursts can cause the paralysis of circuit system, such as big The disasters such as fire, whole mains breakdown is caused, and it is bigger due to damaging, and the repair in later stage is more time-consuming, gives people Electricity consumption bring difficulty, therefore with flame retardant cable come to reduce the damage of fire be very necessary, but due at this stage Used flame retardant cable only has flame retardant effect, it is impossible to good protection circuit, while fire proofing is easily smoldered, to disappearing Anti- work brings difficulty, it is impossible to meets that we are needed to prior art to this at this stage to fireproofing of cable requirement well Reformed.
The content of the invention
It is an object of the invention to provide a kind of flame retardant cable, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides a kind of following flame retardant cable of technical scheme, including inflaming retarding shell, titanium dioxide Carbon air bag, carbon dioxide compression room, metal retaining wall, jet groove, air nozzle, sealing strip, dry powder floor, steel wire, asbestos insulating layer, Vacuum layer, wire insulation and wire stylet, the inflaming retarding shell are provided with dioxide capsule, inside the dioxide capsule Provided with carbon dioxide compression room, the carbon dioxide compression room is provided with metal retaining wall, the carbon dioxide compression formula in both sides up and down The left and right sides is provided with jet groove, is provided with air nozzle in the jet groove, the jet groove is covered by sealing strip, the resistance Dry powder layer is provided with the inside of combustion shell, steel wire is provided with the dry powder layer, asbestos insulating layer, the stone are provided with the inside of the dry powder layer Vacuum layer is provided with inside cotton insulating layer, wire insulation is provided with inside the vacuum layer, is provided with and leads inside the wire insulation Core.
Preferably, the density that the dioxide capsule is set on cable is 2.5 meters one.
Preferably, the sealing strip is inflammable plastic material.
Preferably, wound on the outside of the wire insulation by glass fiber tape.
Preferably, the space among the wire insulation is filled by dry powder.
Compared with prior art, the beneficial effects of the invention are as follows:The flame retardant cable is provided with dry powder layer and dioxide capsule, Dry powder and carbon dioxide can play certain fire extinguishing and prevent fire spreading in the case that in fire spreading, outer layer is ruptured Effect, the fire-fighting work to the later stage offer convenience, and can ensure the safety of circuit to greatest extent, for some small fires It is unlikely to cause short circuit.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention;
Fig. 2 is dioxide capsule cross section structure schematic diagram of the present invention;
Fig. 3 is the conductor cross-section structural representation of the present invention.
In figure:1st, inflaming retarding shell, 2, dioxide capsule, 3, carbon dioxide compression room, 4, metal retaining wall, 5, jet it is recessed Groove, 6, air nozzle, 7, sealing strip, 8, dry powder layer, 9, steel wire, 10, asbestos insulating layer, 11, vacuum layer, 12, wire insulation, 13rd, wire stylet.
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 carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made Embodiment, belong to the scope of protection of the invention.
Fig. 1, Fig. 2 and Fig. 3 are referred to, the present invention provides a kind of technical scheme:A kind of flame retardant cable, including inflaming retarding shell 1, Dioxide capsule 2, carbon dioxide compression room 3, metal retaining wall 4, jet groove 5, air nozzle 6, sealing strip 7, dry powder floor 8, steel Silk 9, asbestos insulating layer 10, vacuum layer 11, wire insulation 12 and wire stylet 13, the inflaming retarding shell 1 are provided with carbon dioxide Air bag 2, the density that the dioxide capsule 2 is set on cable are 2.5 meters one, it is ensured that fire-retardant effect, simultaneously It is unlikely to cause excessive weight to oppress to cable again, the inside of dioxide capsule 2 is provided with carbon dioxide compression room 3, institute State carbon dioxide compression room and be provided with metal retaining wall 4 in both sides about 3, it is recessed that the left and right sides of carbon dioxide compression formula 3 is provided with jet Groove 5, the jet groove 5 is interior to be provided with air nozzle 6, and the jet groove 5 is covered by sealing strip 7, and the sealing strip 7 is inflammable modeling Expect material, it is ensured that allow sealing strip 7 first to catch fire, then eliminate the blocking to jet thrust 6, it is sprayed two when catching fire Carbonoxide, the inner side of inflaming retarding shell 1 are provided with dry powder layer 8, and steel wire 9 is provided with the dry powder layer 8, and the inner side of dry powder layer 8 is set There is asbestos insulating layer 10, the inside of asbestos insulating layer 10 is provided with vacuum layer 11, and the inside of vacuum layer 11 is provided with wire insulation Layer 12, the space of the centre of wire insulation 12 are filled by dry powder, can play certain protective effect to the wire of inside, Inner lead is prevented to be blown, the outside of wire insulation 12 is wound by glass fiber tape, it is ensured that is strapped in wire Together, while play a part of sharing pulling force, the inside of wire insulation 12 is provided with wire stylet 13.
