1. Anti-corona composite enameled wire is the main trend of new product development and the main new growth point of the future market

According to the country's industrial policy of developing products with "low consumption and high efficiency" in the future, variable frequency motors are the key products developed by the country in the future. Anti-corona enameled wires are used in variable frequency motors, which can improve the insulation performance under variable frequency conditions and meet the requirements of anti-corona. , Anti-high frequency pulse current requirements, especially with high partial discharge voltage (corona resistance) performance. Compared with ordinary enameled wires, the pulse resistance life of insulation in the same thick enamel layer is increased by more than 100 times.

The frequency conversion motor is the key development direction of the motor industry. Because it is 30-40% more energy efficient than the general motor, it is a new product that will be promoted and popularized before 2020. After 10 years, the output of variable frequency motors will account for more than 50-70% of all motors, which is a major innovation for the enameled wire industry. According to the forecast, the application of enameled wire in the motor industry will reach 190,000 tons in 2010, 250,000 tons in 2015, and 300,000 tons in 2020. According to the 50-70% frequency conversion motor, the demand for anti-corona enameled wire is 100,000 tons and 150,000 tons respectively. Tons, 200,000 tons, any variety of enameled wire can not reach this development speed. However, the current variable frequency motor is still under development and has not been widely used in industrialization. At present, the national demand for anti-corona enameled wire is less than 10,000 tons, and the domestic supply is less than 5,000 tons, and most of them still rely on imports. It can be seen that the anti-corona enameled wire has a large space for future development and is a new variety with the most development potential. my country's market is huge, and we must catch up and develop vigorously.
