RUPATEX®, class B will revolutionize your transformer design.

Maximize safety, minimize costs

Technical and economic benefits:

  • Tinned by solder dipping, mechanical stripping unnecessary
  • Insulation between primary and secondary winding not required
  • Creepage and leakage distances are included in the wire
  • Considerably faster winding time
  • Small quantities available

Examples of application:

  • Schottky diodes / Output rectifiers


  • Enamel insulated copper wires (magnet wire) (0,2 - 1,0mm, AWG 14-24) + triple insulation acc. with IEC 60950
  • Other diameters available on request
