Abstract
本实用新型提供一种单玻璃丝包聚酰亚胺薄膜和云母带绕包铜包铝扁线，包括导体和绝缘层，所述导体为铜包铝扁线(1)；所述绝缘层为层状结构，沿所述铜包铝扁线的径向依次为聚酰亚胺薄膜(2)、云母带(3)、第一绝缘树脂漆层(4)、单层玻璃丝(5)和第二绝缘树脂漆层(6)。本实用新型使用聚酰亚胺薄膜提高了绕包线的耐电压击穿性能；使用云母提高了绕包线的耐电晕性，使用玻璃丝提高绕包线的强度，增加柔韧性。
The utility model provides a copper-clad aluminum flat wire wrapped with a single glass fiber-wrapped polyimide film and mica tape, comprising a conductor and an insulating layer, wherein the conductor is a copper-clad aluminum flat wire (1); the insulating layer is a layered structure, and along the radial direction of the copper-clad aluminum flat wire are polyimide film (2), mica tape (3), a first insulating resin lacquer layer (4), a single-layer glass fiber (5) and a second insulating resin lacquer layer (6). The utility model uses a polyimide film to improve the voltage breakdown resistance of the wrapped wire; uses mica to improve the corona resistance of the wrapped wire; and uses glass fibers to improve the strength of the wrapped wire and increase its flexibility.
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 single glass fibre 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 4, single-glass silk 5 and the second insulating resin enamelled coating 6 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 single-glass silk is an alkali-free glass wool.
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 wrapped copper clad aluminum flat wire of the utility model single glass fibre bag polyimide film and mica tape is as high-performance motor, electrical equipment winding wire, has high-tech, new material characteristics cheaply;
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.
