Aluminum is not only cheaper than copper, but also as an excellent conductor. It has better flexibility than copper. Its density is only 1 / 3 of that of copper. The electric energy transmitted by aluminum with the same weight is twice that of copper. Therefore, aluminum wire needs larger wire gauge than copper wire to conduct the same current. Compared with copper, another advantage of enamelled aluminum wire is that NEMA standard recognizes aluminum wire as a more advanced enamelled wire. For example, by replacing copper wire with aluminum wire and adopting high-temperature polyester composite polyimide finish, the heat resistance grade can be increased from 200 to 220 The reason is that during the aging test of enamelled copper wire, the catalysis of copper ion promotes the aging of paint film. The enamelling principle of aluminum wire is very similar to that of copper wire. The main difference is that the aluminum rod is easy to oxidize and has a lower melting point, resulting in more harsh cleaning, lower curing temperature or lower VD value. Advantages of enamelled aluminum round wire can be summarized as follows:

enamelled aluminum wire
one Copper and aluminum have good conductivity, heat resistance and corrosion resistance, so they are often used to make all kinds of wires, cables and current carrying parts. The flexibility of aluminum conductor is better than that of copper conductor. In contrast, it is easier to make coils. Because there is a solid oxide film on the surface of enamelled aluminum wire, it has good insulation effect and long service life.
two Because of its good insulation, the heat-resistant temperature of aluminum wire is 20 ℃ higher than that of copper wire.
three The biggest advantage of using aluminum wire is that it is 1 / 3 lighter than copper wire, which greatly reduces the production cost and is easy to adhere to the fixed object.
At present, enamelled aluminum wire is mainly used in the field with relatively simple process technology. The application of enamelled aluminum wire can be summarized into the following industries:
Microwave oven transformer and reactor.
Degaussing coil.
Industrial fan motor.
Industrial sewing motor
Ups and power supply
Power transformer
Household small motor
Air conditioning Motor SP motor
Washing induction motor
Power transformer
Electric welding machine
