For above-mentioned problems of the prior art, the purpose of this utility model is that providing one kind can avoid the occurrence of
State the A class flame-retardant fire-resistant power cables of technological deficiency.
In order to realize above-mentioned purpose of utility model, the technical scheme that the utility model is provided is as follows：
A kind of A classes flame-retardant fire-resistant power cable, including cable core, the cable core are twisted by 3 insulated wire cores；The sky of cable core
Mineral wool rope packed layer is provided with gap；Be sequentially provided with from inside to outside outside cable core low-smoke bittern-free highly fire-proof band lapping layer, high fire-retardance without
The low cigarette oxygen barrier layer of halogen, armor, oxygen barrier belt, high flame resistance, low smoke Halogen external sheath layer；The insulated wire cores by conductor, be coated on
Ceramic fire resistant silicone rubber insulation layer outside conductor is formed.
Further, armor is wrapped using galvanized steel strip bilayer.
Further, external sheath layer is made of the low-smoke halide-free fireproof composite polyolefine material of high fire-retardance.
Further, one layer of oxygen barrier band is extruded outside armor.
A classes flame-retardant fire-resistant power cable provided by the utility model, fire resistance is good, and fire resistance is good, it is compact, not on
Do not ftractureed when sticking up, bending, mounting and installation convenience, simple production process, cost are relatively low, can meet the need of practical application well
Will.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1- insulated wire cores, 1-1- conductors, 1-2- insulating barriers, 2- mineral wool rope packed layers, 3- lapping layers, 4- oxygen barrier layers,
5- armors, 6- oxygen barrier belts, 7- external sheath layers.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with the accompanying drawings and specifically
Embodiment is described further to the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality
With new, it is not used to limit the utility model.Based on the embodiment in the utility model, those of ordinary skill in the art are not having
There is the every other embodiment made and obtained under the premise of creative work, belong to the scope of the utility model protection.
As shown in figure 1, a kind of A classes flame-retardant fire-resistant power cable, including cable core, the cable core it is twisted by 3 insulated wire cores 1 and
Into；The gap of cable core is provided with mineral wool rope packed layer 2；It is wrapped that low-smoke bittern-free highly fire-proof band is sequentially provided with from inside to outside outside cable core
Layer 3, the low cigarette oxygen barrier layer (inner liner) 4 of high-flame-retardanthalogen-free halogen-free, armor 5, oxygen barrier belt 6, high flame resistance, low smoke Halogen external sheath layer 7；
The insulated wire cores 1 are made up of conductor 1-1, the ceramic fire resistant silicone rubber insulation layer 1-2 being coated on outside conductor 1-1.Armor 5 is adopted
It is wrapped with galvanized steel strip bilayer.External sheath layer 7 is made of the low-smoke halide-free fireproof composite polyolefine material of high fire-retardance.Outside armor 5
Extrude one layer of oxygen barrier band.
The beneficial effects of the utility model are：
First, extruding ceramic fire resistant silicone rubber insulation layer 1-2 on conductor 1-1, start when flame temperature reaches 500 DEG C
Generation catalysis burning crust, the cooling of " porcelain " into specific heat capacity very little keep off fiery solid, and this solid can meet fire resistant requirements；
Second, the gap of cable core is provided with mineral wool rope packed layer 2, mineral wool rope is using glass fibre as primary raw material, through surface
Processing forms with special-purpose machinery and sth. made by twisting, has the characteristics such as anti-flammability is strong, oxygen index (OI) is high；Filled using mineral wool rope, it can be ensured that electricity
Cable has preferable roundness, increases cable tensile strength, while also ensure that cable low-smoke non-halogen flame-retardant performance；
Third, using low-smoke bittern-free highly fire-proof band lapping layer 3, not only with high flame resistance, and enable cable more
It is compact, do not ftracture when not upwarping, bending；
Fourth, what inner liner (i.e. the low cigarette oxygen barrier layer 4 of high-flame-retardanthalogen-free halogen-free) material crusted after having heat-insulated, cooling, being thermally decomposed
Effect, substantial amounts of hydrous oxide is filled in material；Hydrone evaporates when heated, can absorb substantial amounts of heat, reduces electricity
The temperature of cable；The vapor of formation can water down the concentration of cable ambient oxygen；The Metal oxide product of burning forms duricrust,
It is coated on outside cable core, prevents flame and heat from spreading and transmit to cable inside；
Fifth, armor 5 using galvanized steel strip bilayer it is wrapped, not only with excellent mechanical performance, and play fire insulation and
Conductive force, one layer of oxygen barrier band is extruded outside armor 5, on the one hand can improve the anti-flammability of cable, on the other hand can reduce
The probability of sheath cracking；
Sixth, external sheath layer 7 is made of the low-smoke halide-free fireproof composite polyolefine material of high fire-retardance, in cable normal operation
Cable can be protected, is not damaged by external mechanical power；In the environment of burning, low-smoke halide-free fireproof composite polyolefine material is swollen rapidly
It is swollen, form the porous carbon layer of densification, fire retardant during burning in sheath is decomposed, absorb comburant surface heat play it is fire-retardant
Effect；Fire retardant discharges the oxygen of large quantity of moisture dilution combustible surface simultaneously, and the activated magnesia for decomposing generation is attached to
Combustible surface, the progress of burning is further prevented, play cable-flame retardant effect.
A classes flame-retardant fire-resistant power cable provided by the utility model, fire resistance is good, and fire resistance is good, it is compact, not on
Do not ftractureed when sticking up, bending, mounting and installation convenience, simple production process, cost are relatively low, can meet the need of practical application well
Will.
Embodiment described above only expresses embodiment of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model patent scope can not be interpreted as.It should be pointed out that the ordinary skill for this area
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
