Three-phase transformers from THS-Transformatoren Franz Hölsch GmbH are designed for applications where stable and uniform energy distribution in the three-phase network is essential. They are used wherever systems must be reliably supplied with multiple phases while maintaining constant voltage conditions. Thanks to the precise design of the windings and the robust construction, these transformers ensure safe operation even under continuous load conditions.

The designs range from classic three-phase isolation transformers to autotransformers and individually tailored solutions. Standards-compliant construction according to DIN VDE, stable connection solutions and various designs – open or enclosed – allow flexible integration into industrial systems. THS-Transformatoren Franz Hölsch GmbH focuses on functional technology without unnecessary complexity: three-phase transformers that deliver exactly what is required in operation – reliable, resilient and stable over the long term.
