Abstract
The utility model discloses a high-temperature-resistant freezing-resistant double-coating copper flat wire. The high-temperature-resistant freezing-resistant double-coating copper flat wire comprises a copper flat wire conductor adopted as an inner core, and a double-coating layer wrapped at the outer side of the copper flat wire conductor; and the double-coating layer comprises a polyamide-imide layer and a polyesterimide layer. The high-temperature-resistant freezing-resistant double-coating copper flat wire of the utility model has the following advantages that: the double-coating layer not only has excellent adhesion performance, great thermal shock resistance as well as favorable cold resistance and heat resistance, but also can eliminate eddy current and skin effect under high frequency and solve the problem of heat emission of the conductor itself; after a surface is coated with a paint surface layer, the problem of voltage drop which occurs in a situation where a single coating is adopted can be solved, and the high-temperature-resistant freezing-resistant double-coating copper flat wire can greatly satisfy the requirements of enameled copper flat wires used for transformers.
Description
Technical field
The utility model relates to the copper strap wire field, specifically, specially refers to a kind of high temperature resistant cold-resistant two coated copper lenticular wires that freeze.
Background technology
At present, directly weldering property polyester-imide enameling copper strap wire structure is by copper conductor, directly weldering property polyester-imide paint applies and forms, and is mainly used in transformer industry.But, because product thermal endurance class, softening breakdown performance, heat bonding performance, film integrity, freeze-resistant performance etc. do not reach the requirement of special transformer product and the shortcoming such as transformer enameled sheet wire self-heating is fast, cause the transformer of special purpose to damage in the ultralow temperature situation because of long-time the use, cause difficulty and economic loss to manufacturing enterprise.
The utility model content
The purpose of this utility model is to provide a kind of high temperature resistant cold-resistant two coated copper lenticular wires that freeze, and adopts high cold-resistant, heat resistance insulating varnish by the skin at copper strap wire, has overcome the deficiency in the conventional art, thereby has realized the purpose of this utility model.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of high temperature resistant cold-resistant two coated copper lenticular wires that freeze, it comprises that described pair of dope layer comprises polyamide imide layer and polyester-imide layer as the copper strap wire conductor of inner core and two dope layers of being wrapped in the copper strap wire conductor outside.
In an embodiment of the present utility model, described polyamide imide layer is the internal layer of two dope layers, and the polyester-imide layer is the skin of two dope layers.
In an embodiment of the present utility model, the cross section of described copper strap wire internal layer is rectangle.
In an embodiment of the present utility model, the length of described copper strap wire conductor is 2-16mm, and width is 0.8-5.6mm.
The beneficial effects of the utility model are: two dope layers have good adhesion property, good high thermal shock resistance properties and good cold-resistant, heat resistance, and can eliminate generation eddy current and kelvin effect under high frequency, reduce the problems such as conductor self-heating.Surface-coated lacquer painting layer has solved the voltage drop problem of single coating afterwards, can very well adapt to the needs that transformer is used enameling copper strap wire.
Description of drawings
Fig. 1 is high temperature resistant cold-resistant two coated copper lenticular wires that freeze described in the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
As shown in Figure 1, a kind of high temperature resistant cold-resistant two coated copper lenticular wires that freeze described in the utility model, it comprises copper strap wire conductor 100 and two dope layer 200.
Wherein, copper strap wire conductor 100 is as the inner core of whole copper strap wire, and the cross section of copper strap wire internal layer 100 is rectangle, by this structural design, has improved copper strap wire crooked position adhesive force.The length of copper strap wire conductor 100 is 2-16mm, and width is 0.8-5.6mm, can select suitable numerical value according to concrete demand in actual production, and all satisfiability can requirement.
Two dope layers 200 are wrapped in the outside of copper strap wire conductor 100, and two dope layers comprise polyamide imide layer 210 and polyester-imide layer 220.In a preferred embodiment of the present utility model, polyamide imide layer 210 is the internal layer of two dope layers 200, and polyester-imide layer 220 is the skin of two dope layers.Above-mentioned two kinds of coating have improved respectively resistance to elevated temperatures and the high voltage performance of copper strap wire.
The utility model not only can be applied to electronic apparatus, transformer industry widely, and the application of this technology substituted traditional straight weldering polyester-imide enameled sheet wire production Technology, realized the lifting of high cold-resistant, heat-resisting transformer enameling copper strap wire product quality.This novel process technology can be applied in Production of Enamel Wires enterprise widely, for market provides better more high cold-resistant, heat-resisting transformer enameling copper strap wire, and raising surface quality and stable performance guarantee, thereby drive the raising of producing enamelled wire industry technology level, filled up domestic blank, popularizing application prospect is extensive, has promotional value and exemplary role.
The two dope layers of the utility model have good adhesion property, good high thermal shock resistance properties and good cold-resistant, heat resistance, and can eliminate generation eddy current and kelvin effect under high frequency, reduce the problems such as conductor self-heating.Surface-coated lacquer painting layer has solved the voltage drop problem of single coating afterwards, can very well adapt to the needs that transformer is used enameling copper strap wire.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
