0.06mm * 1000 Film Wrapped Stranded Copper Enameled Wire Profiled Litz Wire
Film wrapped shaped litz wire has all the features of litz wire any Mylar wire:high frequency and high voltage. More strands with higher frequency, film wrapped that increase the breakdown voltage over 8000volts, up to 11000volts if there are three layers, that is greatly satisfy the demand of high voltage transformer. Meanwhile Rectangular or flat shape help the design could be smaller and compact, but with better heat dissipation compare with round Mylar Litz wire. Therefore, film wrapped shaped litz wire is an ideal option for high frequency and high voltage application.
1.High voltage withstand: Not matter which film PET or PI, the withstand breakdown voltage is at least 6000 volts with single layer. If the application need higher voltage, we choose double or triple layers, that will be over 10000 volts, that is enough for such application: high frequency, high voltage transformers, E-motors
2.Better sealing performance: No crevice on the film and when the film is wrapped on the wire, there is no gap between two adjacent layers, that protect the wire from water or any other liquid. However, we don’t suggest to immerse the wire into water
3.Double insulated film materials options
