On July 12, 2023, Henan Tengyi Electric welcomed three clients from an Iranian oil extraction company for an on-site visit and acceptance of the second batch of 12 custom 20kV-2500kVA oil-immersed transformers. This visit aimed not only to ensure the quality of the power transformers met customer requirements but also to pave the way for future cooperation opportunities.

Tengyi custom-produced 26 units of 20kV oil-immersed transformers for the Iranian oil company, meticulously designed to meet the client’s specific needs, featuring the following outstanding characteristics:

• Model: 20/0.4kV-2500kVA Oil-Immersed Transformer
• Main Materials: High-quality cold-rolled silicon steel sheets, T1 pure copper coils, Class B high-temperature insulation materials
• Impedance Voltage: 7%
• Connection Group: DYN5
• Temperature Rise: 55/50℃
• Special Customization: Protective boxes for high and low voltage bushings

During performance testing, these transformers excelled, fully meeting the needs of the Iranian clients. Additionally, Tengyi introduced the clients to our production processes and quality control systems. We have fully automated production facilities, from smart robots cutting silicon steel sheets to rigorous quality inspections and testing before each machine leaves the factory, ensuring compliance with local Iranian electrical standards and customer requirements.

Advanced Manufacturing Processes: Tengyi employs high-temperature vacuum drying techniques, effectively enhancing the insulation and explosion-proof performance of power transformers. Meanwhile, an online monitoring system provides real-time surveillance of key production stages to ensure consistent product quality.

Strict Quality Control: We have established a comprehensive quality management system, overseeing every step from raw material procurement and component processing to product dispatch. Our quality inspections cover various aspects such as appearance, performance, and reliability, ensuring stable operation of power transformers in oil extraction enterprises.

Following this visit and acceptance, the Iranian clients expressed great satisfaction with the performance and advantages of the custom 20kV-2500kVA oil-immersed transformers. Tengyi believes this type of power transformer has broad application prospects in the Iranian oil extraction industry.

According to People’s Daily, the Iranian government reports rapid development in the country’s energy sector, with crude oil reserves exceeding 154 billion barrels and natural gas reserves over 33 trillion cubic meters, both ranking first globally. Power transformers with excellent performance and reliable quality will significantly enhance the production efficiency and safety of Iranian oil extraction enterprises, reduce operating costs, and further boost Iran’s competitiveness and standing in the international oil market.

Tengyi looks forward to collaborating with Iranian oil extraction companies to create a bright future together!
