Characteristics Flexible optimization of construction and conductor material possible acc.:
  • HF-performance, resistance
  • high flexibility, flexlife-performance
  • form stability
  • very high electric break down voltage
  • high mechanical robustness
  • optimal round form stability (e.g. for layered winding)
  • high mechanical robustness
  • high flexibility
  • good resistance against water, oils and grease
  • increased electric break down voltage
  • increase of copper filling factor up to 20 %
  • high flexibility and dimensional stability
  • good windability
  • optional with/out outer coating
  • optimal round form stability
    (e.g. for layered winding)
  • specified distance between windings
  • resistance against splicing in combination with high flexibility
  • support for impregnation- & potting processes
  • very high tensile strength possible
  • smallest litz wire constructions with highest tensile strenght and flexlife performance
  • very good processability also for very small litz wires
  • combination of all conductor and coating materials possible
