We have a professional team to guide the installation, and also support on-site installation. We will provide you with more than 2 years of warranty service.

Key Features

1. Optimized for 35kV Medium Voltage Networks

  • Designed specifically for 35kV distribution systems, a common voltage level in industrial zones, rural power grids, and utility substations.
  • Provides efficient and stable step-down transformation from sub-transmission to distribution voltage levels.
  • Supports regional power grid expansion and rural electrification projects.

2. Stable and Balanced Three-Phase Power Supply

  • Delivers consistent voltage across all three phases, ensuring smooth operation of heavy-duty equipment.
  • Ideal for industrial plants, commercial centers, and large-scale energy consumers.

3. Efficient Oil-Immersed Cooling System

  • Uses mineral or natural ester insulating oil for effective heat dissipation and dielectric insulation.
  • Maintains stable operating temperatures even under high load conditions.
  • Enhances transformer lifespan and reduces thermal aging of insulation materials.

4. High Reliability and Robust Construction

  • Built to withstand electrical, mechanical, and thermal stress in demanding environments.
  • Features hermetic sealing or conservator-type oil tanks to prevent moisture ingress.
