1UEW / 2UEW / 3UEW 155 0.25mm / 0.3mm copper enameled magnet wire
There are two uses of magnet wire:
①General purpose, mainly used in motors, electrical appliances,
instruments, transformers, etc., to generate electromagnetic
effects by winding coils, and use the principle of electromagnetic
induction to achieve the purpose of converting electrical energy
and magnetic energy;
②Special purpose, used in electronic components, new energy
vehicles and other fields with special characteristics
requirements, such as fine electronic wires are mainly used for the
transmission of information in the electronics and information
industries, and special wires for new energy vehicles are mainly
used in the production of new energy vehicles manufacture.
