Project Background and Customer Requirements

 

The delivered 10kV 800kVA oil immersed transformers are designed for an industrial power distribution project in Russia, where equipment reliability and long-term operational stability are critical. Due to the local operating conditions, the customer placed particular emphasis on continuous load performance, insulation reliability, and adaptability to harsh climate environments.

 

Based on the project's technical specifications, GNEE ELECTRIC worked closely with the client during the early design stage to confirm key parameters such as rated voltage, cooling method, insulation system, and structural configuration. The final solution was developed to ensure safe and stable operation within the local power network.

Manufacturing Process and Technical Design

 

All 10 units of 800kVA oil immersed transformers were manufactured at GNEE ELECTRIC's production facility under a standardized quality management system. High-quality silicon steel cores and carefully selected winding materials were used to ensure low losses, stable electrical performance, and mechanical strength.

 

The transformers adopt an oil-immersed insulation structure combined with ONAN (Oil Natural Air Natural) cooling, allowing efficient heat dissipation during long-term operation. Special attention was given to the tank structure and sealing process to improve resistance against moisture, dust, and temperature variations, which are common challenges in long-distance transportation and outdoor installation.

 

Throughout the manufacturing process, GNEE ELECTRIC's engineering team carried out multiple internal inspections to ensure each transformer met the approved design drawings and technical requirements.

 

Factory Testing and Quality Assurance

 

Before shipment, every 10kV 800kVA oil immersed transformer underwent comprehensive routine testing in accordance with applicable international standards and project specifications.

 

The testing scope included:

• Winding resistance measurement
• Voltage ratio and vector group verification
• Insulation resistance and dielectric strength tests
• No-load and load loss tests
• Oil tank sealing and visual inspection

 

These tests were conducted by qualified technicians using calibrated testing equipment to ensure accuracy and consistency. Only transformers that passed all inspection stages were approved for final packing and delivery.

 

This rigorous testing process helps minimize on-site commissioning risks and ensures that the equipment can be safely energized upon installation.

Export Packing and Logistics Arrangement

 

Considering the long-distance transportation route to Russia, GNEE ELECTRIC implemented a reinforced export packing solution for this shipment. Each transformer was carefully prepared with moisture protection, shock-resistant support, and secure fixing inside export-grade packaging.

 

The logistics plan was arranged to optimize safety and efficiency during transportation, reducing potential risks associated with handling, loading, and transit. The successful shipment once again demonstrated GNEE ELECTRIC's experience in bulk export delivery and international logistics coordination for power equipment.

 

Supporting Overseas Projects with Practical Experience

 

Russia remains an important market with high technical requirements for electrical equipment, particularly in medium-capacity and high-reliability distribution transformers. The successful delivery of this batch of 10 units of 10kV 800kVA oil immersed transformers highlights GNEE ELECTRIC's ability to support overseas customers with practical engineering solutions rather than standardized products alone.

 

Beyond manufacturing, the company also provides technical documentation, installation guidance, and after-sales support to ensure smooth project execution. This integrated service approach has helped GNEE ELECTRIC build long-term cooperation with customers across different regions.

 

Commitment to Quality and International Cooperation

 

As global demand for stable power infrastructure continues to grow, GNEE ELECTRIC remains committed to delivering reliable, well-tested, and application-oriented transformer solutions. Each overseas project is treated as a long-term partnership, with a strong focus on transparency, product performance, and technical responsibility.

 

The successful shipment to Russia further strengthens GNEE ELECTRIC's international delivery portfolio and reinforces the company's position as a dependable supplier of oil immersed distribution transformers for industrial and utility applications.
