1uew / 2uew / 3uew 155 Enamelled Copper Wire 0.25mm / 0.3mm
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.
