Product Details
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.
