Abstract
The utility model discloses a polyester/polyamide composite enameled round copper wire which comprises a round copper wire (1); the surface of the round copper wire (1) is coated with a first insulating layer (2), the surface of which is coated with a second insulating layer (3); and the first insulating layer (2) is polyester paint and the second insulating layer (3) is polyamide paint. The enameled round copper wire has the advantages of good heat resistance, abrasion resistance, endurance, chemical resistance and electric performance, with a thermal level of 180 DEG C, thus being widely applicable to special motors such as high-frequency variable speed motor, heat-resistant motor and cold-resistant motor, windings of electric appliances and the like.
Description
Technical field
The utility model relates to a kind of enamelling cuprum round line, particularly a kind of compound enamelling cuprum round line of polyester/polyamide that is used to produce motor, electric tool.
Background technology
Common enamelling cuprum round line is usually used in common electric machine, electrical equipment, instrument, transformer, but can't be applicable to the electric tool that runs up, because its temperature resistant grade, resistance to wear are not enough, and when being made into winding wire or coil, need the skeletal fixation moulding, its folding ability, proof voltage, anti-wear performance, heat resistance are lower, and film integrity is also relatively low, and greasy property is not enough.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of polyester/polyamide compound enamelling cuprum round line, and this enamelled wire can be applied to electronic worker's instrument of high request and be fit to the requirement of most motors, high-speed induction motor, transformer.
For solving the problems of the technologies described above the technical solution of the utility model: the compound enamelling cuprum round line of a kind of polyester/polyamide.Comprise copper round wire, first insulating barrier is arranged, be coated with second insulating barrier at first surface of insulating layer in the surface-coated of copper round wire; First insulating barrier is the polyester lacquer, and second insulating barrier is a polyamide paint.
In the compound enamelling cuprum round line of above-mentioned polyester/polyamide, first insulating barrier is molten for one after baked and cured with second insulating barrier.
The beneficial effects of the utility model: compared with prior art, the utlity model has two-layer insulation system, it is the insulating varnish of main component that its first insulating barrier is coated with the polyester with superior heat resistance, high strength and superior isolation performance, second insulating barrier is the insulating varnish of main component coated with polyamide, and become one through baked and cured, have lower coefficient of friction, good heat-resisting, wear-resisting, durable, chemical-resistance and good electric property, and conductor do not had influence.Second insulating barrier of the present utility model and the first insulating barrier intermiscibility are good, and have higher thermal endurance class, and thermal level is 180 grades.Insulating barrier of the present utility model is selected the higher insulating varnish of heat-resisting level for use, makes its high heat-stage performance with 180 ℃, and higher resistance to wear and lubricating ability can be widely used in high-frequency timing, special machines and electrical equipment winding such as heat-resisting, cold-resistant.Its directly the property of weldering property greatly facilitate in the use of enamelled wire on electrical electrode.
Description of drawings
Fig. 1 is a cross section structure schematic diagram of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment
Embodiment.As shown in Figure 1, comprise copper round wire 1, in the surface-coated of copper round wire 1 first insulating barrier 2 based on the polyester lacquer is arranged, having molten after baked and cured based on second insulating barrier, 3, the first insulating barriers 2 of polyamide paint and second insulating barrier 3 in first insulating barrier, 2 surface-coated is one.
Execution mode of the present utility model is not limited to the foregoing description, all belongs within the protection range of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
