High thermal conductivity polyester glass fiber aluminum fla

At present, large and medium sized motors are widely used. Motor winding is usually made by mixing glass wire copper clad wire and glass fiber wrapped hollow copper flat wire and winding by winding machine. Because the motor is often in a high temperature or overload service environment, it seriously affects the reliability and life of the motor. Because of this heat dissipation problem, it is a crucial problem to affect the performance and life of the motor. The traditional solution to the problem of heat dissipation is to introduce coolant fluid into the stator of motor for cooling, or to use fan to cool, or to work in low temperature environment. At present, the winding wires used in the motor are copper enameled wires. Copper enameled wire has the advantages of high conductivity and low resistivity. However, because of the high price of copper and the double increase in recent years, the production cost of copper paint coating line is higher. In order to reduce the cost, aluminum coating line appears in the market. The research on the winding wire of motor increases the heat conductivity, and it is also one of the methods to solve the heat dissipation of the motor. Due to the rapid development of electric power industry in China, especially the rapid development of hydropower, high thermal conductivity poly glass fiber aluminum flat wire for hydro generators is still blank in China. This electromagnetic line needs high temperature resistance grade, thin edge thickness, high voltage resistance requirements and strong mechanical characteristics.

aluminum solves the problem of heat dissipation of motor winding and develops high thermal conductivity polyester glass fiber aluminum flat wire, which has good thermal conductivity to meet the technical requirements of heat resistance of motor winding wire.

High thermal conductivity polyester glass fiber aluminum flat wire can meet the requirements of high temperature resistance grade, thin insulation thickness, high voltage resistance requirements and strong mechanical characteristics of winding group.

The polyester fiber with polyester layer melts first and then cools in the whole process, which can bond glass fiber and enameled aluminum flat wire. Therefore, it is required that the lower the melting point is, the better the melting point is, and the better the levelness is required after melting. After cooling, the flat wire, glass fiber and lacquered fiber are melted into one; These properties of polyester fiber depend on the polymerization degree of lacquered fiber. In the utility model, the polymerization degree of the polyester fiber is 50-80, the optimum ratio between the glass filament and polyester wire in the winding is 35-45%, which makes the polyester wire and glass filament sintering, which can make the electromagnetic wire have excellent electrical properties and good mechanical properties.

High thermal conductivity polyester glass fiber aluminum flat wire is used to draw the conductor in the middle of the winding wire by extrusion drawing method, so that the size of the conductor can reach high precision. It is completed by setting out, annealing, silicone coating, painting, baking, cooling, winding, painting, baking, cooling, polyester coating and cooling process. The whole process is controlled by start-up, stop program and production process programmed by digital driver, which realizes the purpose of utility model.
