A resin carbon fiber bundle and a resin metal wire are wound outside the fireproof insulating layer. The resin carbon fiber bundle and the resin metal wire are coated with a conductive metal layer. The conductive metal layer is coated with a heat conducting insulating layer. The cable provided by the invention has the advantages that the cable has the characteristics of simple structure, long service life, high electricity-heat conversion efficiency, wide working temperature range, no visible light in a working process, small heat hysteresis, fast heating, uniform heating temperature, adjustable electric heating power, wide geometry variation range and the like; in a practical application process, the cable can be used in a standard or non-standard unit form; the electrical performance is stable and reliable; the service life is more than 5 years; and the cable can be used in liquid and air, and can be widely applied to the heating of liquid, air and the like in industry, agriculture and civil fields.
Description
Technical field
The present invention relates to a kind of carbon fiber heating cable, especially relate to a kind of twin-core winding type carbon fiber heating cable.
Background technology
Oneself is widely used the electric-heating technology that the metal material of take is heater in every field.But wire, in the easy oxidation of condition of high temperature lower surface, because oxide layer constantly thickens, has caused effective area by electric current to reduce, and has increased the load of electric current, therefore easily blows.Under the current capacity area of identical permission, low 10 times of strength ratio carbon fiber wiry, in use frangibility.The carbon fiber characteristic intrinsic with it given the performance of its composite material excellence, it has a series of excellent properties such as high specific strength, high ratio modulus, high temperature resistant, corrosion-resistant, endurance, creep resistant, conduction, heat transfer and thermal coefficient of expansion be little, thereby the application in wires and cables industry provides possibility for it.
Summary of the invention
The invention provides a kind of twin-core winding type carbon fiber heating cable, simple in structure, long service life, electric conversion efficiency is high, operating temperature range is wide, in the course of work without the multicore carbon-fibre wire of visible ray.
For addressing the above problem, the present invention adopts following technical scheme: a kind of twin-core winding type carbon fiber heating cable, comprise metal core wire, and its metal core wire is enclosed with fire lagging, and fire lagging is wound with resin carbon fibre bundle and resin metallic wire outward; Described resin carbon fibre bundle and resin metallic wire are wrapped with conductive metal layer, and conductive metal layer is wrapped with the heat conductive insulating layer.
Optimize, above-mentioned twin-core winding type carbon fiber heating cable, be provided with the interference shielding layer of metal wire knitted in its heat conductive insulating layer.
Optimize, above-mentioned twin-core winding type carbon fiber heating cable, its resin carbon fibre bundle forms by some carbon fiber wires are stranded, bonding by resin prepreg between carbon fiber wire.
Optimize, above-mentioned twin-core winding type carbon fiber heating cable, its resin metallic wire forms by some conductive copper wires are stranded, between conductive copper wire, by resin prepreg is bonding, forms.
Advantage of the present invention has: there is simple in structure, long service life, electric conversion efficiency is high, operating temperature range is wide, in the course of work without characteristics such as visible rays; Thermo-lag is little, quick heating, and heating temp is even; Electrical heating power is adjustable; The geometry range of variation is wide, therefore, in actual application, can adopt standard or non-standard unit mode to use; Electric property is stable, and reliable, up to more than 5 years, can be used useful life in liquid and air, can be applied in widely the liquid of industry, agricultural, civil area and air heat etc., thereby the present invention has good value for applications.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below with best embodiment, the present invention is described in detail
.
As shown in Figure 1, the present invention is a kind of twin-core winding type carbon fiber heating cable, comprises metal core wire 1, and its metal core wire 1 is enclosed with fire lagging 2, outer resin carbon fibre bundle 3 and the resin metallic wire 4 of being wound with of fire lagging 2; Described resin carbon fibre bundle 3 and resin metallic wire 4 are wrapped with conductive metal layer 5, and conductive metal layer 5 is wrapped with heat conductive insulating layer 6.Be provided with the interference shielding layer 7 of metal wire knitted in heat conductive insulating layer 6.Resin carbon fibre bundle 3 is by stranded the forming of some carbon fiber wires 31, bonding by resin prepreg between carbon fiber wire 31.Resin metallic wire 4, by stranded the forming of some conductive copper wires 41, forms by resin prepreg is bonding between conductive copper wire 41.Advantage of the present invention has: there is simple in structure, long service life, electric conversion efficiency is high, operating temperature range is wide, in the course of work without characteristics such as visible rays, except above characteristics, thermo-lag of the present invention is little, quick heating, heating temp is even; Electrical heating power is adjustable; The geometry range of variation is wide, therefore, in actual application, can adopt standard or non-standard unit mode to use; Electric property is stable, and reliable, useful life is up to more than 5 years; Applied environment: can use in liquid and air.Can be applied in widely the liquid of industry, agricultural, civil area and air heat etc.Thereby the present invention has good value for applications.
Finally it should be noted that: obviously, above-described embodiment is only for example of the present invention clearly is described, and is not the restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection scope of the present invention.
