Description
Technical field
The invention belongs to field, and in particular to a kind of flame retardant cable of fibrage.
Background technology
It is well known that electricity does using nichrome, Aludirome and Cu alloy material in the big portion of the electric heater of the prior art
Hot body.Due to these electric heating element materials itself inherent characteristics, many deficiencies are there are in use, such as：General nickel chromium triangle
Alloy material, Aludirome and electric heating element made of Cu alloy material, though having plasticity and flexible, electric heating element is in electricity
Surface is oxidizable during heating use, thereby results in that local current is excessive, and temperature is excessive and is blown.At the same time during electric heating
With the presence of visible ray, therefore the thermal efficiency is low.So carbon fiber electrically hot type cable is widely used in a variety of applications now, but current state
Outer import and the domestic carbon fibre of composite material cable cored structure announced all are internal layer carbon fiber glass outer fibrous coverings
The core after cocurrent and parallel constructed dip resin heating cure is used, but it is all in uneven thickness there are fiberglass insulation,
In the presence of by bending, torsion is easy to crack the defects of, when applied to power cable core due to certain point the defects of, just forms whole electricity
Cable damages.
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the present invention provides a kind of flame retardant cable of fibrage.
Technical solution：A kind of flame retardant cable of fibrage, including conductor wire core, core separation layer, insulating layer, cable every
Absciss layer and flame retardant sheath layer；The cross section of the conductor wire core is semicircle, and conductor wire core is externally provided with insulating layer, the conductor wire
Core separation layer is equipped between core and insulating layer；The cable separation layer is using 3K carbon fibers, 6K carbon fibers, 3K nickel-coated carbon fibers
Either 6K nickel-coated carbon fibers wrap up in that bag two is twisted or hinge joint conductor wire cores braiding together form braiding number of spindles for 16 ingots or
24 ingots；The flame retardant sheath layer is extruded on the cable separation layer.
As an optimization：The core separation layer is non-woven fabrics separation layer.
As an optimization：The insulating layer is flame-proof polyvinyl chloride or low-smoke halogen-free polyolefin insulated with material layer.
As an optimization：The restrictive coating is flame-proof polyvinyl chloride or low-smoke halogen-free polyolefin material guards layer.
Beneficial effect：The present invention is not only simple in structure, service life is long, plasticity is good, and the cable produced is in identical work(
Under the conditions of rate (5 watts or so), the temperature that each fiber is reached is essentially identical (60-70 DEG C), but the voltage phase difference used is very big,
3K carbon fibers 21V, 6K carbon fiber 16V, 3K nickel-coated carbon fibers 4.5V, 6K nickel-coated carbon fibers 3.7V.

Fig. 2 is the detection structure schematic diagram of the present invention.
Embodiment
The technical solution in the embodiment of the present invention will be clearly and completely described below, so that the technology of this area
Personnel can be better understood from advantages and features of the invention, so as to make apparent boundary to protection scope of the present invention
It is fixed.Embodiment described in the invention is only part of the embodiment of the present invention, instead of all the embodiments, based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Embodiment
As shown in Figure 1, a kind of flame retardant cable of fibrage, including conductor wire core 1, core separation layer 2, insulating layer 3, cable
Line separation layer 4 and flame retardant sheath layer 5；The cross section of the conductor wire core 1 is semicircle, and conductor wire core 1 is externally provided with insulating layer 3,
Core separation layer 2 is equipped between the conductor wire core 1 and insulating layer 3；The cable separation layer 4 is fine using 3K carbon fibers, 6K carbon
Dimension, 3K nickel-coated carbon fibers or 6K nickel-coated carbon fibers are wrapped up in the braiding of conductor wire core 1 that bag two is twisted or links together and are formed, and compile
It is 16 ingots or 24 ingots to knit number of spindles；The flame retardant sheath layer 5 is extruded on the cable separation layer 4.The core separation layer 2 is
Non-woven fabrics separation layer.The insulating layer 3 is flame-proof polyvinyl chloride or low-smoke halogen-free polyolefin insulated with material layer.The restrictive coating 5
It is flame-proof polyvinyl chloride or low-smoke halogen-free polyolefin material guards layer.
Using carbon fiber and nickel-coated carbon fibers as basic material in the present invention, compare different size fiber heating power, temperature
