Film-wrapped wire refers to an enhanced insulated stranded wire that wraps one or more layers of insulation film around a standard stranded wire at a certain overlap rate. It offers good voltage resistance and high mechanical strength. The product's working voltage is up to 1000Vrms, and the working frequency can reach 500kHz. It is widely used in various high-frequency and high-voltage power conversion equipment.
