Oil-immersed Transformers Product Details: Discover the superior features and technology integrated into our transformers.
Oil-immersed transformers are essential power tools widely utilized in power systems for seamless voltage conversion and efficient power transmission. They are meticulously crafted to meet high current demands and large capacity requirements with outstanding stability and reliability, ensuring uninterrupted power flow.

 

Model Meaning: Decode the specifications and attributes of our transformer models.

 

Performance Characteristics: Unveiling the superior features that set our transformers apart.

1. Winding structure: Innovative design for enhanced performance.
The high-voltage winding employs a multi-layer cylindrical, continuous, or connecting continuous structure to enhance winding shock distribution. This design ensures minimal magnetic leakage, high mechanical robustness, and exceptional resistance to short circuits.

2. Iron core design: Engineered for efficiency and reduced energy loss.
Crafted from premium quality cold rolled grain-oriented silicon steel sheets, our iron core design employs a full diagonal seam stacking method. This approach significantly minimizes no-load loss and reduces no-load current, maximizing efficiency.

3. Fastening and anti-loosening: Built for durability and stability.
Each core and winding is tightly secured with advanced fastening measures, including self-locking anti-loosening nuts on the high and low voltage leads. The non-hanging center structure can withstand transportation vibrations, ensuring all fasteners remain secure during extended operation.

4. Vacuum processing: Ensuring optimal moisture control.
Our transformers undergo vacuum drying for coils and cores, with transformer oil vacuum-filtered and injected. This process is designed to minimize internal moisture, enhancing the transformer's longevity and performance.

5. Oil tank design: Intelligent design for adaptability.
The oil tank features corrugated sheets with a breathing function to accommodate oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height, optimizing space usage.

6. Other features: Compact, efficient, and aesthetically pleasing.
Showcasing a beautiful appearance and compact size, these transformers require minimal installation space and present a maintenance-free solution, ideal for various applications.
Widely used across power plants, substations, industrial and mining enterprises, as well as in rural power grids, these transformers excel in power distribution systems.

 

Environment and Requirements: Ensuring optimal operational conditions.
Ambient temperature: Engineered to perform between -25°C and +40°C. For optimal performance, the ambient temperature should typically range from -25°C to +40°C.
Altitude limit: Designed for high-altitude reliability. Operational altitude should not exceed 1000m to maintain efficiency.
Air humidity: Keeping humidity in check. To ensure longevity, relative humidity should remain under 90% at a temperature of +25ºC.
Installation place: Optimal conditions for peak performance. Choose an installation site free from corrosive gases and noticeable dirt, to maintain the integrity and performance of the equipment.

 

Maintenance and upkeep: Ensuring longevity and reliability.
Regular inspection: Routine checks for sustained efficiency. Conduct frequent inspections of oil levels and perform oil insulation strength tests. Should any issues arise, replace transformer oil promptly to maintain optimal function.
Stable operation: Safeguarding consistent performance. To maintain stable transformer operation, prevent overloads, short circuits, and other irregularities to ensure continuous efficient power supply.
Safety attention: Prioritizing safety and compliance. Before installation, evaluate the plant's ventilation and fire prevention measures, ensuring compliance with technical specifications for secure, correct installation.


Order process: Streamlined for your convenience.

Factory Scene: Where innovation meets craftsmanship.

Certificates: Assuring quality and compliance.
