  • Three-phase high current transformer1 or 3 phases
  • Vacuum varnished
  • Power from 1 VA to 50 kVA
  • Cheap and economical production due to several company locations
  • Small transformers wound automatic
  • Large transformers wound with a thick wire machine with 1700 mm width for the bobbin and automatic wire positioning
  • More power due to optimisation via computer program
  • Each transformer is calculated individually according to customer specification and standards
High current transformer


Field of application


Welding transformers, heating technology, testing transformers, resistance welding technology


Description


Three-phase transformers, built as high current transformers. The mounting must be done in a way that a convection through the cooling channels is possible. The block terminals are shock proof conform to VBG4. With our impregnation under vacuum the transformers have a very low hum-noise.
