Abstract
The utility model discloses a copper flat wire. The center of the copper flat wire is provided with a copper conductor, wherein the outer surface of the copper conductor is sequentially provided with a polyamide-imide composite lacquer coating and a terylene glass fiber sintered layer from the inside to the outside. In the utility model, an outer layer of the copper flat wire does not need to be coated with insulating lacquer, and baking is not needed in a manufacturing process, which not only reduces the energy consumption but also reduces the pollution; the copper flat wire has good performances of wear resistance and scraping resistance; and the copper flat wire has high temperature resistance index and good humidity resistance and can be widely applied to the stator windings of a large-sized thermal generator unit and a nuclear generator unit.
Description
Technical field
The utility model relates to a kind of electric wire, particularly a kind of copper strap wire that is widely used in the stator winding of large-scale thermal power machine group and large nuclear-power unit.
Background technology
What copper strap wire of the prior art had carries out copper strap wire earlier after the enamel-cover, again at skin process double glass fiber sintering, the copper strap wire of producing like this wear-resisting, the scratch resistance performance is not high, if be applied to the stator winding of large-scale thermal power machine group and large nuclear-power unit, easy damaged enamel-cover layer, electrical property reduces.
The utility model content
The purpose of this utility model provides a kind of wear-resisting, copper strap wire that the scratch resistance performance is high.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of copper strap wire, its center is a copper conductor, the outer surface of described copper conductor is provided with the compound lacquer coat of polyamides-acid imide, the compound lacquer coat outer surface of described polyamides-acid imide is provided with dacron glass yarn sintered layer, wherein, described dacron glass yarn sintered layer is the blending body of dacron thread and glass fiber yarn.
The beneficial effects of the utility model are:
1. because the skin of copper strap wire of the present utility model need not apply insulating varnish, need not cure, reduce energy consumption.
2. because the skin of copper strap wire of the present utility model is the blending body sinter layer of dacron thread and glass fiber yarn, be that the copper strap wire of double glass fiber sinter layer is wear-resisting, the scratch resistance performance is all good than traditional skin.
3. heatproof index height of the present utility model, good, the long service life of humidity resistance.
Description of drawings
Accompanying drawing 1 is the structural representation of copper strap wire of the present utility model.
In the accompanying drawing: 1, dacron glass yarn sintered layer; 2, the compound lacquer coat of polyamides-acid imide; 3, copper conductor.
Embodiment
Below in conjunction with embodiment shown in the drawings the technical solution of the utility model is done following detailed description the in detail:
As shown in Figure 1, the center of copper strap wire of the present utility model is a copper conductor 3, the outer surface of copper conductor 3 scribbles the compound lacquer coat 2 of polyamides-acid imide, be surrounded with the mixed yarn of dacron thread and glass fiber again in the outside of the compound lacquer coat 2 of polyamides-acid imide, form the dacron glass yarn sintered layer 1 of one deck through numerical control high frequency sintering at outer surface again, the compound lacquer coat 2 of polyamides-acid imide is insulating barrier with dacron glass yarn sintered layer 1.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
Claims (2)
1. copper strap wire, its center is a copper conductor, it is characterized in that: the outer surface of described copper conductor is provided with the compound lacquer coat of polyamides-acid imide, and the compound lacquer coat outer surface of described polyamides-acid imide is provided with dacron glass yarn sintered layer.
2. a kind of copper strap wire according to claim 1 is characterized in that: described dacron glass yarn sintered layer is the sintering cambium layer of the blending body of dacron thread and glass fiber yarn.
