Abstract
The utility model discloses a Class 240 polyimide/polyamide composite enameled round copper wire which comprises a copper lead; a first insulation layer is coated on the surface of the copper lead; a second insulation layer is coated on the surface of the first insulation layer; the first insulation layer is polyimide paint, and the heat class of the first insulation layer is Class 240; and the second insulation layer is polyamide insulating paint. By adopting the structure, the enameled round copper wire has excellent heat impact resistance, radiation resistance, overload and ultra-low temperature adapting function, lower friction coefficient, good heat resistance, wear resistance and better electrical insulation performance, greatly improves the wear resistance of the product, provides lower friction coefficient, can adapt to high-speed winding, improves the protection to the electrical insulation performance of the enameled round copper wire, and improves the production efficiency; and lubricant is coated on the surface of the second insulation layer, so that the second insulation layer has good lubricity and wear resistance.
Description
Technical field
The utility model relates to enamelling cuprum round line, especially a kind of 240 grades of compound enamelling cuprum round line of polyimide/polyamide.
Background technology
Common enamelling cuprum round line is usually used in the coil windings of common electric machine, electrical equipment, electronic instrument, transformer etc., its temperature resistant grade general all 220 grades and below, for superhigh temperature resistant, radioresistance, overburden enamelling cuprum round line that special purpose needs, the prior art level generally can only provide the highest 220 grades of thermal level enamelling cuprum round line.In addition, common enamelling cuprum round line not fitting into coiling at a high speed and producing owing to the skin-friction coefficient height, wear no resistance, and production efficiency reduces.
The utility model content
The utility model technical issues that need to address are to provide a kind of 240 grades of compound enamelling cuprum round line of polyimide/polyamide, environment such as the superhigh temperature resistant that this enamelling cuprum round line energy special purpose needs, radioresistance, overburden, as high-tech areas such as nuclear reactor, Aero-Space, Aerospace Satellites, simultaneously the surface has lower coefficient of friction, resistance to wear preferably, can adapt to the high speed needs that wind the line.
The technical solution of the utility model is: a kind of 240 grades of compound enamelling cuprum round line of polyimide/polyamide, comprise copper conductor, described copper conductor surface is coated with first insulating barrier, this first surface of insulating layer is coated with second insulating barrier, described first insulating barrier is a polyimide varnish, its thermal level is 240 grades, and described second insulating barrier is a polyamide insulating varnish.
As preferably, described first insulating barrier and second insulating barrier are molten to be one.
As preferentially, described second surface of insulating layer also is coated with lubricant.
The utility model compared with prior art, have following remarkable advantages and innovation: first insulating barrier is 240 grades of polyimide varnishs with radioresistance, excess load, anti-ultralow temperature ability, make enamelling cuprum round line described in the utility model have good heat shock resistance, radioresistance, excess load, ultralow temperature adaptive functions, can be useful for aspects such as special industry such as Aero-Space, nuclear energy, Aerospace Satellite, be that the domestic whole world is the best at present to such an extent as to particularly adapt to the superhigh temperature state; Second insulating barrier is coated to be the insulating varnish of main component with the polyamide, and molten with first insulating barrier be one, have lower coefficient of friction, good thermal endurance, resistance to wear and electrical insulation properties preferably, improved the resistance to wear of product greatly and lower coefficient of friction is provided, can adapts to high speed and wind the line, raising promotes production efficiency to the electrical insulation properties protection of enamelling cuprum round line; Scribble lubricant at second surface of insulating layer, make it have good lubricity and resistance to wear.
