Key Features
  • Optimized for 35kV Medium Voltage Networks: Designed for 35kV distribution systems, common in industrial zones and rural power grids. Provides efficient step-down transformation from sub-transmission to distribution voltage levels.
  • Stable and Balanced Three-Phase Power Supply: Delivers consistent voltage across all phases, ensuring smooth operation of heavy-duty equipment and reducing voltage fluctuations.
  • Efficient Oil-Immersed Cooling System: Uses mineral or natural ester insulating oil for effective heat dissipation and dielectric insulation. Maintains stable operating temperatures under high load conditions.
  • High Reliability and Robust Construction: Built to withstand electrical, mechanical, and thermal stress in demanding environments. Features hermetic sealing to prevent moisture ingress.
