Abstract
The invention provides a high-temperature-resistant cable which comprises a cylindrical conductor made of high-strength pure copper, the diameter of the conductor is 0.2-4 mm, and a layer of silver is sprayed and plated on the surface of the pure copper conductor. A glass fiber layer wraps on the outer surface of the silver-plated layer, and the thickness of the glass fiber layer is 0.02-0.06 mm. A carbon fiber layer coated with Si is arranged on the outer side of the glass fiber layer, and a heat insulation layer formed by mixed powder of graphite and silicon carbide is filled between the carbon fiber layer and the glass fiber layer. A layer of insulation protection sleeve made of polyvinyl chloride wraps on the periphery of the carbon fibers. High temperature resistance of the cable is greatly enhanced due to the glass fiber layer and the carbon fiber layer coated with Si. In addition, high temperature resistance of the cable is also greatly improved due to filling of graphite and silicon carbide.

Background technology
At present, high temperature place electric power supply system equipment link has both at home and abroad reached higher level with power cable, 30 traditional high temperature-resistant cables are started with from the material of cable often, choose resistant to elevated temperatures insulation or sheath material, to reach resistant to elevated temperatures purpose, but often namely be no more than 300 degrees centigrade, from some high temperature occasion, also have one section gap, the cable of therefore being badly in need of developing a kind of superhigh temperature resistant and stablizing continuous firing.Therefore, the cable that a kind of superhigh temperature resistant is provided and can stablizes continuous firing is those skilled in the art's urgent problems.
Summary of the invention
In order to solve the problems of above-mentioned existence, the present invention aims to provide a kind of superhigh temperature resistant and can stablize the high temperature-resistant cable of continuous firing.
The invention provides a kind of high temperature-resistant cable, comprise conductor, described conductor is the high strength fine copper, and described pure cu conductor is cylindric, and diameter is 0.2mm-4mm, surperficial spraying plating one deck silver of described pure cu conductor; Described silver coating appearance coats the layer of glass layer, and the thickness of described glass layer is 0.02-0.06mm; Described glass layer is provided with one deck outward and applies the carbon fiber layer of Si, stuffed heat insulated layer between described carbon fiber layer and described glass layer, and described thermal insulation layer consists of the mixed-powder of graphite and carborundum; Periphery parcel one deck insulating sheath of described carbon fiber, described insulating sheath consists of polyvinyl chloride, after described cable parcel protective jacket, is drawn into type through at the temperature of 80-120 degree centigrade in the pressing element model.
Further, described conductor can be two, and described two conductors are parallel is spaced,
Described glass layer parcel.
Further, the thickness of described thermal insulation layer is 1mm-2mm, and the mass ratio of graphite and carborundum is 2:1.
Further, the temperature of the drawing of described cable processing is 100 degrees centigrade.
In the present invention, this high temperature-resistant cable comprises conductor, and described conductor is the high strength fine copper, and described pure cu conductor is cylindric, and diameter is 0.2mm-4mm, surperficial spraying plating one deck silver of described pure cu conductor; Described silver coating appearance coats the layer of glass layer, and the thickness of described glass layer is 0.02-0.06mm; Described glass layer is provided with one deck outward and applies the carbon fiber layer of Si, stuffed heat insulated layer between described carbon fiber layer and described glass layer, and described thermal insulation layer consists of the mixed-powder of graphite and carborundum; Periphery parcel one deck insulating sheath of described carbon fiber, described insulating sheath consists of polyvinyl chloride, after described cable parcel protective jacket, is drawn into type through at the temperature of 80-120 degree centigrade in the pressing element model.
At first, described glass layer and apply the setting of the carbon fiber layer of Si, strengthened the heat-resisting quantity of cable greatly; In addition, the filling of graphite and carborundum, also significantly improved the heat-resisting quantity of cable.
