Description
Technical field
This utility model relates to the guider of trachea, particularly superhigh temperature flexible fire-proof cable.
Background technology
Along with the fast development of national economy and improving constantly of living standards of the people, society's power consumption greatly increases.Respectively
Planting the steep increasing of electrical equipment consumption, electrical fire accident increases severely the most therewith.According to statistics, the annual breaking out of fire of China about more than ten ten thousand
Rise, direct property loss more than 10 hundred million yuan.Wherein, the electrically reason such as electric wire short circuit, over loading, electric equipment fault cause
Fire account for the 30% of sum, the frequency of electrical fire and the loss caused and all occupy first of all kinds of fire.Electrically
In fire, electric wire the fire caused accounts for half.Therefore about the fire-retardant of electric wire and fire safety problem people
Increasingly pay attention to, more and more higher to the fire-retardant of electric wire and fire protection requirement.
Fireproof cable in early days refers to the cable with fire-retardant or fire resistance, nowadays typically refers in particular in fireproof cable industry
With magnesium oxide for the mineral insulated cable insulated or the cable with similar performance, and use copper sheath as the protection of cable
Set, its advantage is that resistance is little, can use as earth lead, and its shortcoming is that the fusing point of copper only has 1083 DEG C, limits heatproof effect
Really.
The high-temperature resistant grade of the most most stringent of Britain BS6387 standard regulation fireproof cable is 950 DEG C at present
(180min).
Utility model content
The purpose of this utility model is to overcome the point of prior art, it is provided that temperature resistant grade height, good, the heatproof of flameproof effect etc.
Level is the superhigh temperature flexible fire-proof cable of the twice of transmission fireproof cable.
The purpose of utility model is achieved through the following technical solutions: superhigh temperature flexible fire-proof cable, including core
Unit, ceramic tape, packed layer and oversheath, it is characterised in that: described ceramic tape internal package has five core unit,
Described core unit includes core, Muscovitum belt, insulating barrier and glass belt, and core is arranged on the central shaft position of core unit
Put, core is surrounded with Muscovitum belt, insulating barrier and glass belt successively, blank between described ceramic tape and core unit
Region is provided with packed layer, is surrounded with stainless steel sleeve fireprotection layer, is surrounded with oversheath outside stainless steel sleeve fireprotection layer outside ceramic tape.
The cross section of described core unit is circular, and described core unit circumference each other is tangent.
The external diameter of described core is 4mm, and the thickness of Muscovitum belt is 0.1mm～0.3mm, and the thickness of insulating barrier is
0.5mm～1mm, the thickness of glass belt is 0.1mm～0.5mm, and the thickness of ceramic tape is 0.1mm～1mm, and stainless steel sleeve is prevented
The thickness of fire bed is 0.2mm～0.5mm, and the thickness of oversheath is 1mm～2mm.
The described stainless steel sleeve in stainless steel sleeve fireprotection layer is wrinkle stainless steel sleeve.
This utility model has the advantage that by being respectively provided with the mica tape that thickness is 0.1mm～0.3mm outside core
Layer, thickness be the insulating barrier of 0.5mm～1mm, thickness be the glass belt of 0.1mm～0.5mm, add the heatproof within cable
Grade；By be respectively provided with outside online core unit thickness be the ceramic tape of 0.1mm～1mm, thickness be 0.2mm's～0.5mm
Stainless steel sleeve fireprotection layer, thickness are the oversheath of 1mm～2mm, thus enhance the high temperature resistant grade of Exterior cable, whole cable
Temperature resistant grade high, flameproof effect is good, and temperature resistant grade is the twice of transmission cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-ceramic tape, 2-packed layer, 3-oversheath, 4-core, 5-Muscovitum belt, 6-insulating barrier, 7-glass fibre belt
Layer, 8-stainless steel sleeve fireprotection layer.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described, but protection domain of the present utility model is not limited to
The following stated.
As it is shown in figure 1, superhigh temperature flexible fire-proof cable, including core unit, ceramic tape 1, packed layer 2 and oversheath 3.
Described ceramic tape 1 internal package has five core unit, described core unit to include core 4, Muscovitum belt 5, insulation
Layer 6 and glass belt 7, core 4 is arranged on the cental axial position of core unit, and core 4 is surrounded with Muscovitum belt 5, absolutely successively
Edge layer 6 and glass belt 7, between described ceramic tape 1 and core unit, white space is provided with packed layer 2, Muscovitum belt 5
Having good effect of heat insulation, place the temperature of the heat increase cable outer layer that core 4 produces itself, described insulating barrier 6 is adopted
Using ceramic polyolefine material, it has good heat insulation, thermal insulation, gear fire effect, it is possible to burn in 950 ~ 1000 DEG C of flame
90min, also can extend to more than the 180min time, in the case of superhigh temperature has flame, nonflame, cannot not have meltedly, do not drip, do not take off
The feature such as fall, and does not results in spot fire, can burn till hard ceramic-like armour body, and temperature is the highest, pottery after time the longest burning
Shape armour body is the hardest；It is surrounded with stainless steel sleeve fireprotection layer 8 outside ceramic tape 1, outside stainless steel sleeve fireprotection layer 8, is surrounded with oversheath 3,
The fusing point of stainless steel sleeve fireprotection layer 8 is higher than the fusing point of traditional copper sheathing fireprotection layer, and flameproof effect is more preferable.
In the present embodiment, the cross section of described core unit is circular, and described core unit circumference each other is tangent.
In the present embodiment, the external diameter of described core 4 is 4mm, and the thickness of Muscovitum belt 5 is 0.1mm～0.3mm, insulation
Layer 6 thickness be 0.5mm～1mm, the thickness of glass belt 7 is 0.1mm～0.5mm, the thickness of ceramic tape 1 be 0.1mm～
1mm, the thickness of stainless steel sleeve fireprotection layer 8 is 0.2mm～0.5mm, and the thickness of oversheath 3 is 1mm～2mm, by the conjunction of thickness
Reason is arranged further up to strengthening fireproof effect.
In the present embodiment, the described stainless steel sleeve in stainless steel sleeve fireprotection layer 8 is wrinkle stainless steel sleeve, in being used for preventing
The corrosion and damage of portion's core.
The above is only preferred implementation of the present utility model, it should be understood that this utility model is not limited to herein
Disclosed form, is not to be taken as the eliminating to other embodiments, and can be used for other combinations various, amendment and environment, and
Can be modified by above-mentioned teaching or the technology of association area or knowledge in contemplated scope described herein.And this area
Change that personnel are carried out and change, the most all should be in rights appended by this utility model without departing from spirit and scope of the present utility model
In the protection domain required.
