Mult istranded Self Bonding Copper Litz Wire Taped Mylar Litz Wire With High Voltage
High frequency litz wire is made of single insulated copper wires twisted together.
Insulation of copper wires is made of polyurethane. This fact makes it easy to tin terminals of winding. High dielectric strenght can be achieved by one or multiple wrapping polyester tape (Mylar), polimide tape, kapton tape, etc. Despite this, the litz wire has an excellent flexibility.
Usually litz wire is supplied in round cross-section. However it can be profiled and made in square or rectangular cross section to optimize the winding area.
