Development of Different Types of Enameled Wire


    Xinyu-enameledwire manufacture a good range of Enameled Copper Wire that ensures high insulation and the capability to withstand extreme of high temperature and other mechanical aberration and wear and tear. These wires are utilized among various application areas like that of electric equipment/appliance and household.

    Acetal Enameled Wire: The acetal enameled wire is one of the earliest varieties in the world. It was put into the market by Germany and the United States in 1930, and the Soviet Union has also developed rapidly. There are two kinds of polyvinyl formal and polyvinyl acetal. The study of the age is successful. Although the enameled wire has a low temperature resistance (105 ° C, 120 ° C), it is widely used in oil-immersed transformers due to its excellent high temperature hydrolysis resistance. This property has been notarized by countries all over the world. There is a small amount of production, especially the acetal enamelled flat wire used to make transposition conductors for use in large transformers.

    Polyester Enameled Wire: In the mid-1950s, the polyester enameled wire lacquer based on dimethyl terephthalate was first developed by West Germany. Due to its good heat resistance and mechanical strength, the paint process is wide and the price is low. It has become the main product that dominates the enameled wire market. However, due to the poor thermal shock resistance of polyester enameled wire and easy hydrolysis under high temperature and high humidity conditions, the polyester enameled wire as a single coating in the late 1970s is no longer produced in West Germany and the United States, but in Japan, China and Southeast Asia. Still in large quantities and used. The statistics in 1986 show that the output of polyester enameled wire in China accounts for 96.4% of the total output. After 10 years of hard work, the varieties of enameled wire have been developed, but the gap is very large compared with developed countries.

    Domestic polyester modification has also done a lot of work. THEIC modification and imine modification have been researched and developed. However, due to the slow adjustment of the enameled wire structure, the production of these two kinds of paints is still not large. So far, the voltage drop problem of modified polyester enameled wire still needs to be paid attention to everyone.
