It is provided with ground wire inside total screening braid and positioned at position of the line between shielding aluminum plastic composite band.
Preferably, the line is to there are four shielding aluminum plastic composite band settings, and being uniformly arranged on total screening braid
Inside.
Preferably, there are two the refractory material settings, and line is uniformly arranged on in shielding aluminum plastic composite band
Portion.
Preferably, the material of the refractory material is set as band, and processing method is wrapped.
Optionally, the refractory material is set as fiber, and processing method is braiding.
Optionally, the refractory material is set as plastics, and processing method is to squeeze out.
Preferably, fireproof data cable be applied to skyscraper, megastore, network center, undergrond street, marine ship or
Person's fire safety and the related place of fire-extinguishing and lifesaving.
Preferably, the minimum temperature of fireproof data cable fire resisting is 750 DEG C.
Preferably, the shortest time of fireproof data cable fire resisting is 90 minutes.
Advantageous effect
The utility model provides a kind of fireproof data cable.Has following advantageous effect：The spy of insulation core wire outer cladding
Different refractory material will not melt because of the effect of flame and high temperature or fragmentation, this characteristic determine that it can effectively be reduced absolutely
Contact between edge layer and air and open fire reduces the production quantity of flame.In addition, ambroin is in the cladding of refractory material
It can be decomposed because of high temperature, but residue will not be scattered flame retardant coating, while conductor can be isolated because of the cladding of refractory material with open fire, i.e.,
It can guarantee that data cable conductor in flame is not short-circuit, breaking, and electric power sum number more basic under fire condition can be met
According to transmission requirement.
Description of the drawings
Fig. 1 is the utility model fireproof data cable structural schematic diagram；
In figure：1- fireproof data cables, 3- oversheaths, the total screening braids of 4-, 5- lines are to shielding aluminum plastic composite band, 6-
Refractory material, 7- insulating layers, 8- conductors, 9- ground wires.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The all other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of fireproof data cable, including fire resisting data electricity
Cable 1 is provided with oversheath 3 outside fireproof data cable 1, and the inner homogeneous of oversheath 3 is enclosed with total screening braid 4, total to shield
The inner homogeneous setting for covering braiding layer 4 is wired to shielding aluminum plastic composite band 5, and line is equal to the inside for shielding aluminum plastic composite band 5
Even to be provided with refractory material 6, refractory material 6 is internally provided with insulating layer 7, and the inside of insulating layer 7 is enclosed with conductor 8, total to shield
It covers 4 inside of braiding layer and position of the line between shielding aluminum plastic composite band 5 is provided with ground wire 9.
Line is to there are four the shielding settings of aluminum plastic composite band 5, and being uniformly arranged on the inside of total screening braid 4.It is resistance to
There are two the settings of fiery material 6, and is uniformly arranged on inside of the line to shielding aluminum plastic composite band 5.The material of refractory material 6 is first
Choosing is set as band, and optional material is fiber, plastics.Applied to skyscraper, megastore, network center, undergrond street, ocean
Ship or the related place of fire safety and fire-extinguishing and lifesaving.
In use, by the refractory material of insulation core wire outer cladding, will not melt because of the effect of flame and high temperature or
Fragmentation, this characteristic determine that it can effectively reduce the contact between air and open fire of insulating layer 7, reduce the generation of flame
Amount.In addition, ambroin can decompose in the cladding of refractory material 6 because of high temperature, but residue will not be scattered flame retardant coating, simultaneously
Conductor 8 can be isolated because of the cladding of refractory material with open fire, and it is not short-circuit, continuous to have reached guarantee data cable conductor in flame
Road, and the transmission requirement of electric power more basic under fire condition and data can be met.
Different from the data cable of conventional structure, the utility model is coated with outside the insulating layer 7 of every insulation core wire
Special refractory 6.The refractory material can effectively obstruct adjacent conductor 8 under flame condition and prevent short circuit, and can keep away
Exempt from conductor and blown by open fire to lead to open circuit.In Initial Stage of Fire, cable still has the guarantees such as low-voltage power supply and communication transfer rescue
Function.
The slow-burning wire after refractory material is coated according to performance requirement with different pitches pair twist two-by-two, forms four altogether
The twisted pair wire of color line pair, when stranding, each pair of twisted pair wire was all coated with shielding aluminium-plastic tape 5, at cable four to shielded pair
Center addition ground wire 9.
Total screening braid 4 outside at cable is that braiding coats, and then outermost one layer of extrusion meets requirement of mechanical strength
Oversheath 3.The fireproof data cable after sheath is squeezed out by one timing of thermal-flame (standard recommendation temperature is 750 DEG C) burning
Between after (standard recommendation time be 90min), open circuit will not be formed because conductor is blown, and due to special fire proofed wood between conductor
Effective barrier of material, will not occur short circuit phenomenon.Moreover, the fireproof data cable after burning still has most
Basic data transmission capabilities.
Meet GB/T 19216 and IEC 60331 and other about circuit integrity test required standard to obtain
The fire resistance of defined.The fireproof data cable transmission performance cover Cat5E, Cat6, Cat6A, Cat7, Cat7A, Cat8 with
