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 high fire-retardance fireproof power cable, including cable core, outside cable core wrapped alkali-free glass fibre band around
Covering 3, alkali-free glass fibre band lapping layer 3 extrudes LSOH anti-flaming oxygen barrier layer 4 outside, outside LSOH anti-flaming oxygen barrier layer 4
Galvanized steel strip armor 5 is set, low-smoke and halogen-free flame retardant polyolefin jacket layer 6 is extruded outside galvanized steel strip armor 5.The cable core by
Three insulated wire cores 1 are twisted, and the insulated wire cores 1 include conductor 1-1, the wrapped mica tape flame retardant coating 1- on conductor 1-1
2, ceramic composite fire silicone rubber insulation layer 1-3 is extruded on mica tape flame retardant coating 1-2.Conductor 1-1, which is selected, meets GB/
T3956-2008 the 1st kind, the 2nd kind or the 5th kind plating metal or not the annealing copper conductor of metal cladding.The cable core gap filling
Flame retardant inorganic paper string packed layer 2.
The utility model has advantages below：
First, conductor 1-1, which is oxygen-free copper bar, draws the wire formed, wire process puts down its surface using structure is pressed
Whole, mica tape flame retardant coating 1-2 can closely be attached to conductor 1-1 surfaces, be advantageous to electric fields uniform distribution, reduce cost；
Second, setting mica tape flame retardant coating 1-2 outside conductor 1-1, ceramic composite fire silicone rubber insulation layer 1- is extruded
3, effect is when fire occurs, and plays double-deck superposition protective effect, and fire-resistant silicon rubber is exactly to utilize its organosilicon chain combination oxygen
SiClx family, starts catalysis burning crust when flame temperature reaches 500 DEG C, and the cooling of " porcelain " into specific heat capacity very little keeps off fire
Solid, this solid can meet fire resistant requirements.Generate after the wrapped mica tape flame retardant coating 1-2 chance fire on conductor 1-1 and do not melt
White stiff shell silica, there are good insulating properties, and with certain mechanical strength and water-fast, to ensure electricity
The safe operation of certain time is kept when cable catches fire；
Third, filled using flame retardant inorganic paper string packed layer 2, the outer double-deck wrapped alkali-free glass fibre band lapping layer 3 of cable core,
Product fire resistance is set to reach highest level A classes；LSOH anti-flaming oxygen barrier layer 4 is extruded outside alkali-free glass fibre band lapping layer 3,
Caused duricrust after burning, it can effectively resist scene of fire water and pour, prevent water from being permeated to insulating barrier within a certain period of time；Together
When, when cable is by mechanical oscillation, duricrust can play a part of protecting insulating barrier, avoid insulating barrier from being broken by mechanical oscillation
It is bad；
Fourth, by setting galvanized steel strip armor 5 and low-smoke and halogen-free flame retardant polyolefin jacket layer 6, fire-retardant, stop is played
Flame and heat-insulated effect.
High fire-retardance fireproof power cable provided by the utility model, processing and manufacturing is convenient, cost is reasonable, can meet simple resistance to
Fire, the additional spray of fire resisting, the requirement of fire resisting additional mechanical vibration test, the needs of practical application can be met well.
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
