Abstract
The utility model discloses a double insulation layer copper flat wire. A copper conductor is used as center; a polyimides film and a terylene glass fiber sintered layer are disposed on the external surface of the copper conductor successively from inside out. The breakdown voltage and the fracture elongation of the double insulation layer copper flat wire of the utility model are much higher than the standards; so the wire has a wide application prospect in large and medium-sized high voltage motor, special electric machine, wind power and electric appliance winding having high safety standard requirements.
Description
Technical field
The utility model relates to a kind of electric wire, the double-insulated layer copper flat wire in particularly a kind of winding that is applied to large high-voltage motor, specific type of electric machine, wind-powered electricity generation and electrical equipment.
Background technology
In the prior art, in the production process of copper strap wire, can produce waste gas, the refuse of excess, cause environmental pollution, the outermost layer of the copper strap wire that majority is traditional is the insulating varnish that applies, and so just need cure copper strap wire, consumes a large amount of energy, the production cost height.
The utility model content
The purpose of this utility model is at above-mentioned technical deficiency, and the double-insulated layer copper flat wire that a kind of cost is low, combination property is high is provided.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of double-insulated layer copper flat wire, its center are copper conductor, and the outer surface of described copper conductor is provided with polyimide film, and described polyimide film outer surface 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: the discharge capacity of waste gas, refuse is few in the manufacturing process of copper strap wire of the present utility model; The skin of copper strap wire of the present utility model need not apply insulating varnish, need not cure energy savings; Good, the long service life of the electrical property of copper strap wire of the present utility model has lowered user's use cost.
Description of drawings
Accompanying drawing 1 is the structural representation of double-insulated layer copper flat wire of the present utility model.
In the accompanying drawing: 1, dacron glass yarn sintered layer; 2, polyimide film; 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 double-insulated layer copper flat wire of the present utility model is a copper conductor 3, the outer surface of copper conductor 3 is surrounded with polyimide film 2, be surrounded with the mixed yarn of dacron thread and glass fiber again in the outside of polyimide film 2, form the dacron glass yarn sintered layer 1 of one deck through numerical control high frequency sintering at outer surface again, polyimide film 2 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. double-insulated layer copper flat wire, its center is a copper conductor, it is characterized in that: the outer surface of described copper conductor is provided with polyimide film, and described polyimide film outer surface is provided with dacron glass yarn sintered layer.
2. a kind of double-insulated layer copper flat 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.
