Product Description

Product Overview
This 33kV/35kV-class dry-type power transformer is developed for medium-voltage power conversion in demanding industrial and infrastructure environments. Its dry insulation system avoids the use of liquid dielectric and can be configured for mining operations, renewable-energy facilities, utility substations and commercial power distribution.

Technical Highlights

  • Suitable for 33kV and 35kV-class medium-voltage networks with customized low-voltage output.
  • Cast resin insulation provides mechanical strength and stable dielectric performance.
  • Oil-free construction is suitable for locations with strict fire-safety or environmental requirements.
  • Designed for continuous operation under variable load conditions with appropriate thermal management.
  • Optional forced-air cooling can increase the usable capacity where required.
  • Temperature sensors, digital temperature controllers, protective enclosure and alarm functions can be integrated.
  • Transformer construction can be adapted to high-temperature, dusty and humid conditions commonly encountered in African projects.
