Our Process
Step 1: Consultation & Design

We will respond to your inquiry within 1 hour and recommend suitable transformer according to your needs. At the same time, we will provide you with reasonable quotations and payment terms. We have a professional and independent drawing team and technical team, and we will confirm all the contents on the drawing with you within 7 days after payment. The drawing usually contains technical data, weight and parts list.

Step 2: Production & Quality Control

After designing the production drawing, the factory will prepare the stock, produce, and conduct quality inspection before shipment. If you have special accessory requirements, we can provide you with accessories. Our raw materials are strictly screened. In the quality inspection stage, we will provide you with the dual guarantee of QC report and test report to escort your products.

Step 3: Installation & Support

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
  • 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 to10kV/0.4kV). Supports regional power grid expansion and rural electrification projects.
  • 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.
  • 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.
  • 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.
