Transformers and Basic Components/Coils

Schmidbauer only selects high quality metal cores complying to DIN regulations. Depending on application requirements special metal alloys or module constructions are used.

By the way – both of our standard series and the special

constructions fulfil national and international regulations.

Automated core welding, vacuum sealing, Testing of every single unit produced.

  • NC controlled welding for cores complying with EI54 to EI195, including simultaneous welding of mounting brackets.
  • Vacuum sealing with synthetic resin system, insulation class F
  • Transformers e.g. in polyamide housings can be completely and automatically sealed with PU resin.
  • PC based testing are used to check every single transformer unit before leaving our production facilities (amperage, voltage, coil and insulation resistance, phase sequence, high-voltage tests).
