Description
Technical field
This utility model relates to field of cable technology, particularly to a kind of fireproof cable.
Background technology
Cable industry is the second largest industry that China is only second to automobile industry, and product variety Service Efficiency and domestic market are occupied
Rate is all more than 90%, and China, as one of the most most important cable products development & production base, has possessed fire-retardant resistance to the most
Low-temperature resistance fiery, high temperature resistant, low inductance low noise, environmental protection, low smoke and zero halogen, antitermite protection against rodents, waterproof and dampproof etc. a series of have
Special performance and the cable products of special construction, and the most defined certain productivity.
At present, along with security protection guarantee and security of system requirement are improved constantly by society, accordingly for the requirement of cable
Day by day increase, especially fireproof cable.Fireproof cable be widely used in skyscraper, underground railway, undergrond street, large-scale power station and
The place that important industrial and mining establishment etc. are relevant with fire safety and fire-extinguishing and lifesaving, such as, fire-fighting equipment and promptly should to leading lights etc.
The supply line of anxious facility and control circuit.Existing mineral insulated cable, although remain to maintain a period of time after catching fire
Normal power supply, but there is price, complex process, problem that difficulty of construction is big.
Utility model content
The purpose of this utility model is the defect existed for above-mentioned prior art, it is provided that a kind of fire protecting performance is preferable
Cable.
For the attainment of one's purpose, the technical scheme that this utility model provides is:
A kind of fireproof cable that this utility model relates to includes some conductor elements, packing material and successively around wrapping in filling
The braid of outer material side and protection set, it is characterised in that: described conductor element includes conductor thread core and leads around wrapping in successively
Insulating barrier outside body core and mica tape；It also includes conductor support, if the region that braid is enclosed by conductor support is separated into
Dry less space, conductor element is respectively provided in space, and described conductor support center is provided with toughness guide rod, described
Packing material fills up the space between braid, conductor support and conductor element.
The material of described insulating barrier uses low smoke, zero halogen material, uses the insulating barrier that low smoke, zero halogen material is made in burning
Shi Buhui produces harmful gas, plays minimizing air pollution and the impact on human health.
Preferably, the outside of described conductor support is all fixing with the inner ring of braid to be connected, the toughness in conductor support
Guide rod is steel wire twisted wire.
The material of conductor support is ceramic fibre, and ceramic fibre conductor support is separated by each conductor element so that cable
Will not in the short time whole on fire after lost efficacy, can effectively reduce the infringement that cable is caused by fire, enhance tension, antitorque simultaneously
Performance so that cable has stronger security performance.
Preferably, the Internal and external cycle of described braid all scribbles fireproof coating.
Braid uses quartz sand braiding.
Preferably, the described chain armor of copper that protection set is band ripple.The technical program utilizes the heat resistance of copper,
Improve the fire-resistant rank of cable, reduce the danger coefficient of fire.
The technical scheme using this utility model to provide, compared with prior art, has the advantages that
(1) the outer wrapped mica tape of the fire-resisting cable conductor thread core that this utility model relates to, it is ensured that can also continue when 750 DEG C
It is energized more than 2 hours, it is ensured that the information backup time；Ceramic fibre conductor support is separated by each conductor element so that cable
Will not in the short time whole on fire after lost efficacy, can effectively reduce the infringement that cable is caused by fire, enhance tension, antitorque simultaneously
Performance so that cable has stronger security performance.
(2) outermost layer of the fire-resisting cable that this utility model relates to adds bag one layer is the chain armouring of corrugated copper, improves
Security performance, even if when fire, utilizes the heat resistance of copper, improves the fire-resistant rank of cable, reduces the danger of fire
Coefficient.

Detailed description of the invention
For further appreciating that content of the present utility model, this utility model is described in detail in conjunction with the embodiments, real below
Execute example for this utility model is described, but be not limited to scope of the present utility model.
With reference to shown in Fig. 1, a kind of fireproof cable that this utility model relates to includes three conductor elements 1, packing material 6 and
Successively around the braid 2 wrapped in outside packing material and protection set 3, it also includes the conductor support 4 being placed in braid, described
Conductor support 4 region that braid is enclosed be separated into three less spaces, conductor element 1 is respectively provided in this space,
Conductor support center is provided with toughness guide rod 5, and packing material fills up the sky between braid, conductor support and conductor element
Gap.Described conductor element 1 includes again conductor thread core 11 and successively around the insulating barrier 12 wrapped in outside conductor thread core and mica tape 13.
The material of above-mentioned insulating barrier 12 uses low smoke, zero halogen material, uses the insulating barrier that low smoke, zero halogen material is made in burning
Shi Buhui produces harmful gas, plays minimizing air pollution and the impact on human health.
The material of above-mentioned conductor support 4 is ceramic fibre, and the outside of conductor support is all fixing with the inner ring of braid to be connected,
Toughness guide rod in conductor support is steel wire twisted wire.Ceramic fibre conductor support is separated by each conductor element so that cable is not
In the meeting short time, whole rear inefficacies on fire, can effectively reduce the infringement that cable is caused by fire, enhance tension, resistance to torsion simultaneously
Can so that cable has stronger security performance.
Above-mentioned braid uses quartz sand braiding, and the Internal and external cycle of braid all scribbles fireproof coating.
Above-mentioned protection set uses the chain armor of copper of band ripple, utilizes the heat resistance of copper, improves the fire-resistant of cable
Rank, reduces the danger coefficient of fire.
Above in association with embodiment, this utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
