Technical and economic benefits:

  • 50% reduction in the size
    of transformers
  • 65% reduction in the
    weight of transformers
  • Insulation between
    primary and secondary
    winding no longer
    necessary
  • Inter-layer insulation no
    longer necessary
  • Creepage and leakage
    distances are included
    in the wire
  • Encapsulation not necessary
  • Much faster winding time


Examples of application:

  • High Frequency transformers
  • High Frequency transmission devices
  • High Frequency chokes
  • Electronic ballasts

Construction:

  • Enamel insulated copper
    wires (magnet wire)
    (0.02-1.6 mm dia.,
    AWG 13-52)
  • Conductor cross-section
    in compliance with DIN
    or customer requirements

Isolation material:

  • *Polyester foil, 150 °C
    (Mylar©)
  • P.E.N. foil (XR 20), 155 °C
  • **Polyimide foil, 220 °C
