On the basis of litz wire, served litz wire is coated by layers of textile yarn for better mechanical properties, including nylon, polyester, dacron or natural silk. It consists of plural strands of fine wires that are individually insulated, according to specific design and application. USTC wire has a nylon top coat over the regular litz wires to enhance the mechanical properties of insulation coat. Besides, it’ s also conducive to further with impregnation process.
•High frequency application
•Compared with regular litz wire, served litz wire with nylon as protection layer suffers less wire damage during winding and its electrical performance is better
•Solderable and no residue
•High “Q” value and excellent construction
•High flexibility and optimum insulation distance
•Lower temperature on the top of litz wire
•Impregnation solderability above temperatures of 410℃
