Abstract
The utility model provides a polyester double glass fiber-covered polyimide film and mica tape wrapped copper-clad aluminum flat wire, which comprises a conductor and an insulating layer, wherein the conductor is a copper-clad aluminum flat wire (1); the insulating layer is of a laminated structure, and a polyimide film (2), a mica tape (3), a first insulating resin paint layer (4), a double-layer glass fiber (5), a second insulating resin paint layer (6), a polyester layer (7) and a third insulating resin paint layer (8) are sequentially arranged along the radial direction of the copper-clad aluminum flat wire. The utility model uses the polyimide film to improve the voltage breakdown resistance of the wrapping wire; the mica improves the corona resistance of the lapped wire, the glass fiber improves the strength of the lapped wire, and the flexibility is improved.
Description
Technical field
The utility model relates to a kind of wrapped copper clad aluminum flat wire.
Background technology
Enamelled wire is a principal item of winding wire, is made up of conductor and two ones of insulating barriers, and bare wire forms through repeatedly painting, curing behind annealing softening again.But producing is the conformance with standard requirement, satisfy the product of customer requirement again and be not easy, it is subjected to raw material quality, technological parameter, production equipment, factor affecting such as environment, therefore, the mass property of various enamelled wires has nothing in common with each other, but all possesses mechanical performance, chemical property, electrical property, hot property four big performances.
Because motor manufacture level development both at home and abroad is rapid; particularly external high-output power, the try one's best small and exquisite electric machine structure and the environmental protectionization of production process have proposed harsh specification requirement for the lapped wire of motor stator parts: as require lapped wire to have proof voltage, anti-corona, high strength and the good performance of pliability.At present, also there is not to reach fully the lapped wire that as above requires.
Summary of the invention
The purpose of this utility model is to provide a kind of can satisfy proof voltage, anti-corona, high strength and the good lapped wire of pliability simultaneously.
The purpose of this utility model is achieved in that a kind of terylene double glass fiber bag polyimide film and the wrapped copper clad aluminum flat wire of mica tape, comprises conductor and insulating barrier, and described conductor is a copper clad aluminum flat wire; Described insulating barrier is a layer structure, radially is followed successively by polyimide film, mica tape, the first insulating resin enamelled coating, double glazing silk, the second insulating resin enamelled coating, terylene layer and the 3rd insulating resin enamelled coating along described copper clad aluminum flat wire.
The described first insulating resin enamelled coating is silk-covered wire lacquer 1448-2; The described second insulating resin enamelled coating is silk-covered wire lacquer 1448-2; Described the 3rd insulating resin enamelled coating is silk-covered wire lacquer 1448-2.
Described double glazing silk is the two-layer alkali-free glass wool of rightabout coiling.
The beneficial effects of the utility model are:
1, the utility model uses polyimide film to improve the proof voltage breakdown performance of lapped wire; Use mica to improve the corona resistance of lapped wire, use glass fiber to improve the intensity of lapped wire, increase pliability;
2, the utility model terylene double glass fiber bag polyimide film and the wrapped copper clad aluminum flat wire of mica tape be as high-performance motor, electrical equipment winding wire, has high-tech, new material characteristics cheaply; With behind the terylene layer, intensity height, good springiness, resistance to wear are good
3, the utility model uses the partly copper metal of the alternative high price of aluminum metal of low price, saved a large amount of copper resources, in addition, the density of copper cover aluminum is 1/2.45 of fine copper, thereby can alleviate the weight of wire rod unit length significantly, more help China's motor, transformer, and even client unit such as IT information industry uses conveniently and reduces cost;
4, the utility model is a kind of proof voltage, anti-corona, high strength and the good lapped wire of pliability, and simple in structure, easily manufactured, dependable performance, can be widely used in high-voltage motor, and its withstand voltage is 1.3～1.7 ten thousand Kv.
