As an important material, enamel coated copper wire is the main variety of winding wire, which is composed of conductor and insulating layer. After the bare copper wire is softened by annealing, it is painted and baked many times. It has been widely used in motors, transformers, compressors and other industries, as well as new energy vehicles, rail transit, wind power, smart home and other fields.
In order to meet the different requirements in these fields, it is divided into various specifications, such as self-welding polyurethane series, nylon finish paint series, polyester series, polyesterimide coating polyamideimide, polyesterimide series , Corona-resistant paint is used for wires such as frequency conversion motors. In the days to come, the rapid development of modern industry drives a bright future.
The enamel coated copper wires for motors mainly use QZ, QZY, QA and Q(ZY/XY). It has good abrasion and solvent resistance and is able to work in extreme conditions with extreme resistance to very high and very low temperatures. Electric motors are used in many different applications such as fans, pumps, machines, household appliances, power tools.
The enamel coated copper wire for compressors mainly adopts Q(ZY/XY)-2/200. The enameled wire has high requirements on the ambient temperature and refrigerant resistance. Generally, a half-year life test needs to be done in the early stage, and the surface needs to be coated with refrigeration oil.
Plate magnet wire is mainly used for winding coils of electric vehicles, transformers, motors, generators and various electrical equipment. It has excellent electrical conductivity, thermal stability, scratch resistance, solvent resistance, good heat dissipation performance and high magnetic field efficiency when wound into a coil.
Enamelled copper wire for EV mainly uses 180-240 degree flat enameled copper wire. Compared with the round wire, the advantages of the enameled flat wire are that there is no gap, the volume efficiency is large, the space factor is improved, and the motor is miniaturized and high output. The enameled flat wire has low friction coefficient and good winding performance.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for all electrical, electronic and related technologies. Widely used in the European market, also suitable for the Chinese GB standard. For these wires, low-oxygen copper wires are required as conductors, and their production equipment and technology originated in European countries.
Japanese Industrial Standards (JIS) are formulated according to IEC standards for the production and testing of enamel coated copper wires. Widely used in the Japanese market and Japan-related customers. These wires, require low-oxygen copper wire as the conductor and use a different test method than other standards.

The anti-corona square magnet wire can work continuously in an environment of 200 degrees. In addition to good heat resistance, radiation resistance and high abrasion resistance, it also has good corona resistance. Therefore, it is widely used in various frequency conversion speed regulation motors, hoisting motors, elevator motors, etc.
Jintian Copper specializes in the research and development, production, and sales of enameled wire. The main products include corona-resistant enameled copper round (flat) wire, polyester-imide over-coated with Polyamide-imide enameled copper round (flat) wire, and self-solderable polyurethane enameled copper round wire, etc. All products comply with the requirements of the EU ROHS directive and have passed UL safety certification. They are widely used in industries such as new energy vehicles, industrial motors, transformers, compressors, and rail transit. The enameled wire produced by Jintian Copper uses high-quality low-oxygen and oxygen-free copper wire as raw materials, and is equipped with online detection instruments during the production process, which can monitor and adjust the production process in real time, strictly control product quality, and each reel of enameled wire can be traced back. For example, the corona-resistant enameled wires used for inverter-fed motors produced by Jintian Copper can improve the partial discharge performance of the motor and extend the service life of the inverter-fed motors.
