UEW 155 / 180 Self bonding Enameled Copper Wire
Ultrafine self bonding enameled copper wire is a a copper conductor covered with two layers of coating self bonding which may be thermoplastic or thermosetting resins over an monolayer insulating copepr wire made of polyurethane,polyester or other insulation resins.
We expertly conbined diversified self bonding copper wires according to different kinds of insulating coatings and self bonding film.
