Cable generally uses fire-resisting cable, and requires to adapt to cable under the scene of fire wind occurred, the situation such as drench with rain, shake and still need to power
For a period of time, withdraw so as to personnel, rescue.Now in country's cable fire-resisting cable product, mostly using common phlogopite,
Muscovite or the fire-resisting cable of the wrapped making of synthetic mica, fire resistance are difficult to by fire resisting as defined in the standards of AS/NZS 3013
Experiment, also the insulating barrier of some enterprises is mica tape and ceramics silicon rubber composite band, by actual use as can be seen that this
The fire resistance period of structure is shorter, while the flame temperature that can be born is generally 350-3000 DEG C, runs into more than 3000 DEG C of superelevation
Temperature is difficult to bear.Therefore, a novel flame resistant cable by fire resistance test as defined in the standards of AS/NZS 3013 of design has non-
Often wide market prospects.
The content of the invention
In view of this, the utility model is directed to a kind of low-smoke bittern-free highly fire-proof fire-resisting cable, to solve prior art
Middle fire-resisting cable fire resistance period is short, it is difficult to the problem of bearing superelevation flame temperature.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：A kind of low-smoke bittern-free highly fire-proof is resistance to
Thermoelectricity cable, including cable body, set inside cable body and one layer of oversheath are extruded outside many cable cores, cable core, cable core and outer
Gap portion between sheath is provided with oxygen barrier layer；Cable core includes being extruded with calcining cloud successively outside many conductors, every conductor
Master tape and insulating barrier.
Further, calcining mica tape is overlapped mutually by several layers of calcining mica and formed, and the weight between every layer of calcining mica
Folded rate is 40%-50%.
Further, the thickness of calcining mica tape is 0.1-0.3mm.
Further, the thickness of the oxygen barrier layer between outer layer of cable core and oversheath is 0.4-0.6mm.
Further, insulating barrier is made up of crosslinked polyolefin insulating material, and oversheath is by irradiated crosslinking low-smoke and halogen-free flame retardant
Polyolefine material is made.
Further, oxygen barrier layer is made up of thermoplasticity ceramic polyolefine material.
It is described in the utility model relative to prior art, have the advantage that：
(1) a kind of low-smoke bittern-free highly fire-proof fire-resisting cable described in the utility model, mica is calcined around cladding using multilayer
Cable core, while being combined thermoplasticity ceramic polyolefin fireproof oxygen-separation layer, when running into high temperature, thermoplasticity ceramic polyolefin
The rapid curing caking of fireproof oxygen-separation layer, forms ceramic-like solidifying shell, adds the performance of combustion polyolefin insulation material, while isolation
Contact of the mica tape with flame is calcined, so as to realize the harder effect of the higher oxygen barrier layer of temperature.
(2) a kind of low-smoke bittern-free highly fire-proof fire-resisting cable described in the utility model, is hindered using irradiated crosslinking low-smoke and halogen-free
Polyolefin jacket material is fired, so that oversheath has fabulous protective effect, cable normal power-up under superhigh temperature can be made.
