APPLICATION SCENARIO
✅ 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 in many regions.Provides efficient and stable step-down transformation from sub-transmission to distribution voltage levels (e.g., 35kV to 10kV/0.4kV).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 and reducing voltage fluctuations. Ideal for industrial plants, commercial centers, and large-scale energy consumers requiring reliable three-phase power.
✅ 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 or continuous duty 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 outdoor and indoor environments.Features hermetic sealing or conservator-type oil tanks to prevent moisture ingress and maintain oil quality.
