Polyvinylformal Wire Enamels (PVF)

Polyvinylformal wire enamels are suitable for heavy round and rectangular conductors. They provide excellent mechanical stability, superb adherence to copper, and resistance to transformer oil. These highly sophisticated enamels are mainly used in large generators and transformers due to their excellent mechanical properties. In addition to the good dielectric properties, these enamels also show outstanding chemical resistance, which makes the coated wire suitable for use in hermetic applications and in oil filled transformers according to IEC60 851-4. They are also well-suited for the production of flat wires for transposed cables (CTC).
