Brief introduction of enamelled wire industry in China
1.1 definition and classification of enamelled wire industry
Enamelled wire is coated with a layer of insulating coating on the conductor with high purity and high conductivity.
Classification of enamelled wire: general purpose enamelled wire (ordinary wire): it is mainly used for winding wires in general motors, electrical appliances, instruments, transformers and other working places, such as polyester enamelled wire and modified polyester enamelled wire.
Heat resistant enamelled wire: it is mainly used for winding wires of motors, electrical appliances, instruments, transformers and other working places working at 180 ℃ and above. Such as: polyester imide enamelled wire, polyimide enamelled wire, polyester imide / polyamide imide composite enamelled wire.
Enamelled wire for special purpose: it refers to enamelled wire with certain quality characteristics and winding wire used in specific occasions. Such as polyurethane enamelled wire (direct weldability), self-adhesive enamelled wire and anti corona enamelled wire.
1.2 characteristics of enamelled wire industry
With the continuous progress of society and the continuous development of industry, enamelled wire has an extremely broad application field and has become an indispensable main supporting raw material for motor, electrical appliances, household appliances, electronics, communication and transportation products. Especially in recent years, the rapid development of household appliances, the progress of electronic technology and the rise of communication industry, It provides a new space for the application of enamelled wire, adjusts the application proportion in various fields, puts forward higher and updated technical requirements for enamelled wire, and adjusts the structural proportion of enamelled wire. After China's entry into WTO, the enameled wire industry will face competition in domestic and international markets, which also adds a layer of thinking and pressure to the enterprise leaders.
1.3 analysis on industrial chain of enameled wire industry
Enamelled wire products belong to the basic material industry supporting industries such as motor, electrical appliances, household appliances, communication, electronic information, instruments and meters, electric tools and automobiles. They are a long-term product and there are many downstream industries. The upstream industries of enamelled wire mainly include copper, aluminum, paint and other industries.
