Abstract
The utility model relates to an electric material, in particular to a round enamelling copper wire. The utility model comprises a conductor and a composite insulating layer clad outside the conductor, wherein, the composite insulating layer is composed of a pinhole free polyester-imide primer layer and a polyamide imide insulating paint layer, also a lubricating layer is clad on the surface of the polyamide imide insulating paint layer, and lubricating layer formed through coating end product lubricant. The round enamelling copper wire has the advantages of high temperature resistant, freeze resistant, high mechanical strength, good hot piercing performance, high softening and arcing temperature, and because the pinhole free polyester-imide paint is adopted as the primer layer of the composite insulating layer, the continuity and the pinhole performance evidently improved. By using the round enamelling copper wire of the utility model, the motor manufacturer can effectively avoid the problem that the voltage among the coils is not unqualified and the electric discharging problem caused by the paint film pinhole factors, and the performance of the manufactured motor is greatly improved.
Description
Technical field
The utility model relates to a kind of electrical material, relates in particular to a kind of enamelling cuprum round line.
Background technology
The motor manufacturing generally adopts high-speed automated spooling equipment coiling motor coil at present, therefore the various mechanical performances to enamelled wire have proposed higher requirement, high-speed automated spooling equipment requires enamelled wire to have certain mechanical strength, stronger resistance to wear, scratch resistance power and good sliding property also require it to have high temperature resistant preferably and the freezing-resistance energy in some field.Present common enamelled wire not too can satisfy this requirement.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a kind of enamelling cuprum round line that the modern electrical machine manufacturing is used that is more suitable for.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of enamelling cuprum round line, comprise lead and be coated on its outer composite insulation layer, composite insulation layer is by free of pinholes polyester-imide prime coat and be coated on its outer polyamidoimide insulation enamelled coating and form, also is covered with lubricating layer on the insulate surface of enamelled coating of polyamidoimide.
Further, described lubricating layer is to form by the surface-coated finished lubricants at polyamidoimide insulation enamelled coating.
The beneficial effects of the utility model are: the utility model is high temperature resistant, it is freezing to resist, the mechanical strength height, heat is good towards property, the softening temperature height that punctures, and, make the continuity of paint film and pin hole performance significantly improve owing to adopted the prime coat of free of pinholes polyester-imide lacquer as composite insulation layer.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
1. leads, 2. composite insulation layers, 21. free of pinholes polyester-imide prime coats, 22. polyamidoimides insulation enamelled coating among the figure.
Embodiment
A kind of enamelling cuprum round line as shown in Figure 1, comprise lead 1 and be coated on its outer composite insulation layer 2, composite insulation layer 2 is by free of pinholes polyester-imide prime coat 21 and be coated on its outer polyamidoimide insulation enamelled coating 22 and form, surface at polyamidoimide insulation enamelled coating 22 also is covered with lubricating layer 3, and lubricating layer 3 forms by applying finished lubricants.
The utility model is high temperature resistant, anti-freezing, the mechanical strength height, heat is good towards property, the softening temperature height that punctures, and owing to adopted the prime coat of free of pinholes polyester-imide lacquer as composite insulation layer, make the continuity of paint film and pin hole performance significantly improve.The utility model also is specially adapted to the motor of refrigerant compressors such as refrigerator, refrigerator, air-conditioning.
