Quality Control
We apply a documented quality system across incoming, in-process, and final inspection. Quality certifications, QC staffing, and procedures are available on request.
Quality control runs through the whole manufacturing process, from the incoming core steel and conductor to the final test report that leaves with the unit.
Our plant is equipped for both oil-immersed and dry-type distribution transformer production. Detailed equipment lists, automation level, and annual capacity are available on request.
Control points
- Incoming inspection: core steel, conductor, insulation, oil, resin, steel plate
- In-process inspection: core stacking, winding dimensions, insulation clearances
- Drying and impregnation: vacuum, temperature and time records
