Tortech Pty Ltd specialises in designing custom made and stock standard transformers utilising the vast knowledge and technical experience of its Engineering team.

We are capable of designs within the following scope:

  • Three Phase Dry Type Power Transformers up to 2.5MVA and 33kV ratings.
  • Single to Three Phase Converters up to 22kW.
  • Current Transformers and Voltage Transformers at MV and HV ratings.
  • Single Phase Toroidal Transformers up to 10kVA ratings.
  • Three Phase Inductors/Chokes.

Our Single Phase and Three Phase Transformers have been implemented into applications for Commercial, Defence, Medical, Mining, Light Rail & Railway Installation projects.

CAD Drawings and Designs

Our Engineering team are highly proficient at designing and constructing full 2D and 3D AutoCAD drawings. These drawing relate to the transformers, enclosures and all other relevant details required by the client, project managers and manufacturing team. The AutoCAD program used by our team is referred to as BricsCAD.
