Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as a cornerstone in modern power systems, designed for efficient voltage conversion and seamless power transmission. Engineered to meet the high current and large capacity demands, these transformers are epitomes of stability and reliability, delivering unmatched performance in every power system application.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding features a sophisticated multi-layer cylindrical design, whether continuous or connecting continuous, enhancing shock distribution, minimizing magnetic leakage, and offering superior mechanical strength with remarkable short-circuit resistance.

2. Iron core design:
Crafted with high-quality cold rolled grain oriented silicon steel sheets, our iron core utilizes a full diagonal seam stacking method, significantly reducing no-load loss and no-load current for superior efficiency.

3. Fastening and anti-loosening:
Each coil and core is securely fastened with precision-engineered measures. With self-locking anti-loosening nuts and non-hanging center structure, they withstand transportation vibrations, ensuring fastener stability throughout long-term operations.

4. Vacuum processing:
Coils and cores undergo meticulous vacuum drying, with transformer oil being vacuum filtered and injected to effectively minimize moisture, ensuring optimal internal conditions for peak performance.

5. Oil tank design:
Our oil tank features a corrugated sheet with an innovative breathing function, adapting to oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Boasting a beautiful, compact design, these transformers occupy minimal installation space and are ideal maintenance-free solutions, harmonizing aesthetics and functionality.
Perfectly suited for power plants, substations, industrial, mining enterprises, and rural power grids, these transformers are essential in any power distribution system.

 

Environment and Requirements:
Ambient temperature: Should ideally range between a temperate -25°C and a warm +40°C to ensure optimal functionality.
Altitude limit: The installation site should not exceed an altitude of 1000m to maintain performance standards.
Air humidity: Should remain below 90% relative humidity at a comfortable +25ºC to prevent adverse effects on equipment.
Installation place: Select an area devoid of corrosive gases and visible dirt to safeguard the longevity and functionality of the product.

 

Maintenance and upkeep:
Regular inspection: Frequently monitor the oil level and conduct oil insulation strength tests. Promptly replace the transformer oil if anomalies are detected to maintain efficiency.
Stable operation: Ensure stable transformer operation by preventing overloads, short circuits, and other irregularities, safeguarding consistent performance.
Safety attention: Prioritize plant ventilation and fire prevention during installation, adhering strictly to technical specifications for accurate and secure setup.
