Oil-immersed Transformers Product Details: Discover the advanced technology and superior design embedded in our oil-immersed transformers, ensuring robust performance and reliability.
Oil-immersed transformers represent a pinnacle of power equipment innovation, extensively utilized across power systems for efficient voltage conversion and seamless power transmission. They are specially engineered to satisfy the rigorous demands of high-current and large-capacity transformer applications within power systems, offering unparalleled stability and reliability.

 

Model Meaning: Decode the significance behind our model naming conventions to better understand our product line.

 

Performance Characteristics: Experience the exceptional features that make our transformers stand out in the industry.

1. Winding structure: Innovative design for enhanced performance.
The high-voltage winding utilizes a multi-layer cylindrical, continuous, or connecting continuous structure. This sophisticated design enhances shock distribution, minimizes magnetic leakage, ensures high mechanical strength, and offers robust short-circuit resistance.

2. Iron core design: Precision-engineered for efficiency.
By integrating high-quality cold-rolled, grain-oriented silicon steel sheets with a full diagonal seam stacking method, our transformers significantly reduce no-load loss and no-load current, maximizing energy efficiency.

3. Fastening and anti-loosening: Secure and resilient construction.
With rigorous fastening measures, both the core and windings are securely fastened. High and low voltage leads are equipped with self-locking anti-loosening nuts, using a non-hanging center structure to withstand transportation vibrations. All fasteners feature fastening nuts to ensure stability throughout long-term operation.

4. Vacuum processing: Enhanced longevity through precision techniques.
Our coils and cores undergo a meticulous vacuum drying process, while transformer oil is vacuum filtered and injected to minimize internal moisture, thereby extending the transformer's lifespan.

5. Oil tank design: Ingenious, space-saving innovation.
The oil tank is designed with corrugated sheets that incorporate a breathing function to accommodate oil volume changes due to temperature fluctuations. This eliminates the need for an oil storage cabinet, thereby reducing the transformer's overall height.

6. Other features: Sleek and efficient design.
Our transformers boast a beautiful appearance and compact size, minimizing installation space requirements. They are the ideal maintenance-free solution for modern applications.
Widely implemented in power plants, substations, industrial facilities, and rural power grids, our transformers excel within power distribution systems.

 

Environment and Requirements: Adapted to thrive in varying conditions.
Ambient temperature: Optimal range for performance. The transformers are generally designed to operate efficiently between temperatures of -25°C and +40°C.
Altitude limit: Suitable for diverse geographical locations. The maximum operational altitude is limited to 1000 meters to ensure optimal performance.
Air humidity: Enduring high humidity conditions. Designed to function effectively in environments with relative humidity not exceeding 90%, at temperatures of +25ºC.
Installation place: Choose the optimal environment. Select installation areas free from corrosive gases and excessive dirt to maintain the integrity and lifespan of the transformers.

 

Maintenance and upkeep: Promote longevity and efficiency.
Regular inspection: Routine checks for uninterrupted operation. Perform regular inspections of the oil level and conduct oil insulation strength tests. Promptly replace transformer oil if any issues are detected to ensure continued performance.
Stable operation: Safeguard against disruptions. Ensure the transformer operates stably by preventing overloads and short circuits, thereby avoiding any abnormalities.
Safety attention: Prioritize safety in every installation. Prior to installation, assess plant ventilation and fire prevention measures. Adhere strictly to technical specifications for proper and safe installation.
