The cable core body is tieed up yarn packed layer 7 by alkali-free glass fiber and isolated.Open the outer surface of the Tao Kai ceramic fire-resistant polyolefin oxygen barriers bed of material 4
If threaded notch.So that in the case where ensureing fire resistance, cable bending degree is improved.By opening up threaded notch so that one kind has
The enviroment protective ceramic cable Integral bending degree of wearing of high life improves 3-6 ° relative to existing cable, is more favorable for connecting up, suitable for more
Wide working environment.Also include, external protection 15；External protection 15 is set on the outside of cable stock, passes through company with cable stock
The wing 16 is connect to be fixedly connected；Filling is by the particle between 0.1-0.25 millimeter of diameter in the space of cable stock and external protection 15
The sand of composition.External protection can be also only arranged in cable stock with the same length of cable stock and easily catches fire or need to protect emphatically
Certain section of shield.The both ends of the surface of external protection can ensure that sand will not flow out by rubber seal.Also other may be selected in the prior art
Sealing means, sand is fixed in the space of cable stock and external protection 15.Quality of rubber materials can be selected in external protection.When one
Enviroment protective ceramic ignition of cable kind with the high life or during by flame calcination, can be damaged therewith after external protection catches fire.
The external protection of fire can drop with sand, so as to delay fire resistance period.Or during calcination damage external protection, sand drippage will reduce fire
Flame size, or even knock down the flame.Also include, cable tray 18, the material of cable tray 18 elects fiberglass as, has corrosion resistance
It is good, high-strength light, the feature that insulation and thermal insulation performance is good and manufacturability is excellent.Cable tray 18 is shaped as cuboid, in cable
String holes 181 is opened up on bracket 18.Cable tray 18 is installed in cable stock 17, cable stock 17 is worn out of string holes 181
Go out.Cable stock and cable tray are installed in bellows.Cable stock is suspended in bellows by the support of cable tray,
Bellows plays a protective role to cable stock.
The temperature acquisition end of temperature sensor 182 is embedded and the side of cable tray 18, the temperature letter of collection cable tray 18
Breath.The model of temperature sensor 182 uses DA-02-CX.The output end of temperature sensor 182 connects with the input of controller 183
Connect, controller 183 elects 80C51 or 89C51 as.Temperature sensor 182 sends the temperature information collected to controller
183, when temperature information is more than design temperature information, the output end of controller 183 is connected with buzzer 184, controls buzzer
184 buzzings, send prompt tone.Generally, cable tray 18 is multiple that two neighboring interval 10m, 15m or 20m are set
Put.
In a kind of optional embodiment, cable tray 18 can be used for fixing on cable, be easy to one kind to have the high life
Enviroment protective ceramic cable distribution.Engaging lug 185 can be set on cable tray, for by screw, rivet etc. by cable support
Frame 18 is installed on wall or other positions.
The oxygen index (OI) of high oxygen index (OI) oxygen barrier layer 5 is more than 38, and the thickness of high oxygen index (OI) oxygen barrier layer 5 is 2-4mm.Tao Kai ceramics
The thickness 5.5-6.5mm of the fire-resistant polyolefin oxygen barrier bed of material 4.Ceramic refers in high molecular polymer, such as plastics, rubber and thermoplastic
Property elastomer, add functional material, in the case of the aerobic or anaerobic more than 300 DEG C, sinter adamantine ceramics into
Shape inorganic matter housing supporter.Fire resisting is to be amenable to that high temperature or high temperature resistance must be lived, that is, meets standard within the regular hour
The ability of stability, integrality thermal insulation and other expectation functions specified in fire resistance test；Oxygen index (OI) (OI) is in regulation bar
Under part, sample maintains the minimum oxygen concentration needed for stable burning (having flame combustion) in N2 and O2 mixed airflows.It is to weigh
High polymer combustibility；But combustibility is weighed nor absolute with oxygen index (OI), if the oxygen index (OI) of polyethylene is 17.4,
The oxygen index (OI) of polystyrene is 18.1, and comparatively, polyethylene should be than polystyrene more easy firing, but actually polystyrene
What is burnt is more violent, because polystyrene flame transmission speed is more fast again than polyethylene.This is due to the specific heat of polystyrene
Hold and decomposition temperature is relatively low caused.In addition to oxygen index (OI), specific heat capacity, thermal conductivity, fusing point, decomposition temperature and the ignition of high polymer
Temperature, flame propagation velocity, surface combustion speed also all reflect the combustibility of high polymer；Oxygen index (OI) is that having the feelings of flame
To a sign of high polymer combustibility, the fireproof oxygen-separation layer of middle pressure fire resisting and the insulating refractory of low-voltage cable, base under condition
It is in the case of nonflame, anaerobic on this；For Tao Kai ceramics fire-resistant polyolefin in the case of nonflame, anaerobic, temperature reaches 300
Start slowly to crust more than DEG C, temperature continues to raise, crust speed accelerate with the ramp-up rate of temperature, formed ceramic without
Casing body supporter.Most important middle pressure fire-resisting cable design is also a bit the most key, seeks to accomplish to crosslinked polyethylene
Insulating barrier carries out temperature protection, protects crosslinked polyetylene insulated layer in loading 10KV, 950~1000 DEG C × 90~180min of flame
Under conditions of, internal crosslinked polyetylene insulated layer does not melt, and does not soften, and is delivered to crosslinked polyetylene insulated layer during off-test
Temperature will be less than 160-180 DEG C, can so make it that crosslinked polyetylene insulated layer is protected well.Cable stock exists
The common cooperation of above-mentioned sandwich construction, progressively absorbing and cooling temperature and insulation under, ensure that the temperature of crosslinked polyetylene insulated layer is less than
160-180 DEG C of requirement.The alkali-free glass fiber yarn main component of alkali-free glass fiber yarn packed layer is silica, is a kind of highly stable
Inorganic material, nontoxic, heat resisting temperature will not produce harmful flue gas up to more than 650-1000 DEG C after heated；Alkali-free
The section of glass fibre yarn is cylindrical, has space between every yarn after filling stranding, forms passage, this passage can play very well
Thermolysis, heat caused by cable normal operation can pass through these various passages and alkali-free glass fiber yarn sheet
Body is radiated；The heat that exterior conductive is come in during fire can also be conducted by these passages and glass fibre yarn.Interior fiber
Belting layer and outer fiber belting layer carry out fire resisting guarantor also due to its excellent heat conduction, radiating and heat-resisting new energy to cable stock
Shield.In order to ensure cable cut convenience, and cause section fire resistance it is stronger, along cable stock every 30m radially open up it is more
Group V-shaped groove, the interior filling Tao Kai ceramics polyolefin of V-shaped groove form V-type ring 13.V-shaped groove when opening up, V-shaped groove
Bottom land is located in the Tao Kai ceramic fire-resistant polyolefin oxygen barriers bed of material 4.When use, cutting V-shaped ring 13, you can smoothly to cable
Cut.And cut surface by the V-type ring 13 that Tao Kai ceramic polyolefin is formed to Tao Kai ceramic fire-resistant polyolefin oxygen barrier material
Layer 4 has bond strength preferably, and low smoke and zero halogen external sheath layer 1, steel-tape armouring layer 2 and outer fiber belting layer 3 are protected
Shield.
In a kind of optional embodiment, the V-type ring opens up some stomatas.It is more favorable for radiating.Stomata opens up direction
To be parallel with diametric(al).
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses
Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power
The protection domain that profit requires is defined.
