According to the classification of insulating materials, enamelled wires can be divided into acetal enamelled wires, polyester enamelled wires, polyurethane enamelled wires, modified polyester enamelled wires, polyesterimide enamelled wires, polyesterimide / polyamide imide enamelled wires, polyimide enamelled wires, etc.
According to the purpose of enamelled wire, it can be divided into:
1. General purpose enamelled wire (ordinary wire) is mainly used for general motors, electrical appliances and instruments. Winding wires in transformer and other working places, such as polyester enamelled wire and modified polyester enamelled wire.
2. Heat resistant enamelled wire; It is mainly used for winding wires of motors, electrical appliances, instruments, transformers and other working places working at 180 ° C and above, such as polyester imide enamelled wire, polyimide enamelled wire, polyester imide / polyamide imide composite enamelled wire, etc.
3. Enamelled wire for special purpose; It refers to the enamelled wire with certain quality characteristics and winding wire used in specific occasions, such as polyurethane enamelled wire (direct weldability), self-adhesive enamelled wire, etc.
