Abstract
The utility model discloses a cable with high temperature resistance, include the wire that forms by the transposition of stranded carbon fiber exothermic wire, its characterized in that: the wire surface from inside to outside in proper order the cladding have insulating layer, filling layer, insulating layer and ceramic fibre pipe, the insulating layer includes the PVC protective sheath and gathers the tetrafluoroethylene coating, the filling layer is foam sponge, the insulating layer is the glass fiber weaving layer. The utility model has the advantages of it is following and effect: the wire passes through the life that the insulating layer has improved the wire on the one hand, and the on the other hand coating can not receive mechanical damage and chemical attack by the guardwire, and high temperature resistant, the filling layer provides certain clearance at the back foam sponge meeting the thermal expansion that is heated simultaneously, improves the radiating effect, glass fiber can endure 500 DEG C -800 DEG C high temperature, and this makes this cable to use in the high temperature use environment, has enlarged application scope.
Description
Technical field
The utility model relates to connecting line field, is specifically related to a kind of high temperature resistant cable.
Background technology
The application of electric wire is mainly divided into three major types: electric power system, the information transmission system and plant equipment and instrument system.The electric wire product that electric power system adopts mainly contains aerial bare electric wire, bus-bar (bus), power cable, rubber cover cable, aerial insulated cable), branch cable (replace part bus), electromagnetic wire and power equipment electrical equipment electric wire etc.Electric wire for the information transmission system mainly contains local cable, camera cable, electronic cable, radio frequency cable, fiber optic cable, data cable, electromagnetic wire, power communication or other composite cables etc.In plant equipment, instrument system, except aerial bare electric wire, almost other all products all have application, but mainly power cable, electromagnetic wire, data cable, instrument and meter cable etc.
Electric wire product is mainly divided into five large classes: bare wire and bare conductor goods, power cable, electric cable for electric equipment, communication cable and optical fiber and electromagnetic wire.Wherein power cable principal character conductor outward squeeze (around) bag insulating barrier, as aerial insulated cable, or several core stranded (phase line of corresponding electric power system, zero line and ground wire), as the above aerial insulated cable of two cores, or increase restrictive coating again, as plastics/rubber cover electric wire.
But some industries require more and more higher to the resistance to elevated temperatures of electric wire, common multifunctional cable adopts the material such as conventional polyvinyl chloride, cross-linked polyolefin as insulation and sheath material, and these materials are in high temperature occasion, and easily old saying is until cable breaks down rapidly, thus this problem is those skilled in the art's problem demanding prompt solutions.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of high temperature resistant cable meeting high temperature occasion and use.
For achieving the above object; the utility model provides following technical scheme: a kind of high temperature resistant cable; comprise by the stranded wire of multi-strand carbon fiber heating wire; described wire outer surface is coated with insulating barrier, packed layer, thermal insulation layer and ceramic fiber tube from inside to outside successively; described insulating barrier comprises PVC protective sleeve and perfluoroethylene ene coatings; described packed layer is foam sponge, and described thermal insulation layer is fiberglass braided layer.
Of the present utility modelly to be set to further: on described fiberglass braided layer, spraying plating has tin layers.
Of the present utility modelly to be set to further: described fiberglass braided layer is woven mesh.
The utility model has following advantage: wire arranges by PVC protective sleeve in insulating barrier and perfluoroethylene ene coatings the useful life that improve wire on the one hand, and coating can not be mechanically damaged and chemical corrosion by guardwire on the other hand, and high temperature resistant; Packed layer foam sponge meeting expanded by heating after being heated, provides certain gap, improves radiating effect simultaneously; Fiberglass braided layer can well carry out decortication process, wire can be kept to have good circularity simultaneously, and glass fibre can tolerate the high temperature of 500 DEG C ~ 800 DEG C simultaneously, and this makes this cable can use in applied at elevated temperature environment, expands the scope of application.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, wire; 2, insulating barrier; 21, PVC protective sleeve; 22, perfluoroethylene ene coatings; 3, packed layer; 4, thermal insulation layer; 5, ceramic fiber tube; 6, tin layers.
Embodiment
With reference to Fig. 1, the utility model embodiment is described further.
A kind of high temperature resistant cable; comprise by the stranded wire 1 of multi-strand carbon fiber heating wire; described wire 1 outer surface is coated with PVC protective sleeve 21, perfluoroethylene ene coatings 22, foam sponge, fiberglass braided layer and ceramic fiber tube 5 from inside to outside successively; on fiberglass braided layer, spraying plating has tin layers 6, and fiberglass braided layer is woven mesh.
Wire 1 arranges by PVC protective sleeve 21 in insulating barrier 2 and perfluoroethylene ene coatings 22 useful life that improve wire 1 on the one hand, and coating can not be mechanically damaged and chemical corrosion by guardwire 1 on the other hand, and high temperature resistant; Packed layer 3 foam sponge meeting expanded by heating after being heated, provides certain gap, improves radiating effect simultaneously; Fiberglass braided layer in thermal insulation layer 4 can be good carrying out decortication process, wire 1 can be kept to have good circularity simultaneously, glass fibre can tolerate the high temperature of 500 DEG C ~ 800 DEG C simultaneously, this makes this cable can use in applied at elevated temperature environment, expand the scope of application, the thickness of ceramic fiber tube 5 is preferably 15mm, has high temperature resistant, resistance to chemical attack, heat shock resistance, low thermal conductivity, the performance such as high insulation resistance and high elastic modulus.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
1. a high temperature resistant cable; comprise by the stranded wire of multi-strand carbon fiber heating wire; it is characterized in that: described wire outer surface is coated with insulating barrier, packed layer, thermal insulation layer and ceramic fiber tube from inside to outside successively; described insulating barrier comprises PVC protective sleeve and perfluoroethylene ene coatings; described packed layer is foam sponge, and described thermal insulation layer is fiberglass braided layer.
