High voltage FIW3 / FIW 4 enameled copper winding wire for transformer

FIW enameled wire fully insulated and weldable (zero defect) technology makes it have better winding performance and welding performance than traditional TIW three-layer insulated wire, so it can be used as a substitute for TIW wire, allowing customers to use it at a lower cost Produce smaller size transformers. The finished outer diameter of FIW enameled wire has a wide range of choices, which allows customers to choose the appropriate specifications more flexibly to optimize product performance and cost.
