2UEW / 3UEW self adhesive enameled copper wire for speaker voice coils

The use of self-adhesive enameled wire (Self-Bonding Wire) with composite coating to wind the coil has changed the traditional transformer manufacturing mode. The coil can be made into a whole by only hot melting, which has certain mechanical properties and moisture-proof insulation properties. Therefore, the self-adhesive magnet wire can be wound into a skeletonless coil and without dipping, which can shorten the manufacturing cycle of magnetic components such as electro-acoustic equipment, and greatly improve the efficiency of mass production.
