Oil-immersed Transformers Product Details:
Oil-immersed transformers: Essential power equipment seamlessly integrated into power systems for efficient voltage conversion and robust power transmission. Engineered to cater to high currents and large capacities, these transformers are epitomes of stability and reliability, ensuring consistent performance in demanding environments.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding employs a sophisticated multi-layer cylindrical or continuous structure. This design strategically enhances shock distribution, minimizes magnetic leakage, and offers exceptional mechanical strength and superior short-circuit resistance.

2. Iron core design:
Featuring high-grade, cold-rolled, grain-oriented silicon steel sheets utilizing an advanced full diagonal seam stacking method, our design significantly cuts down on no-load loss and current, promoting operational efficiency.

3. Fastening and anti-loosening:
Both the core and windings are secured using robust fastening techniques. Equipped with self-locking anti-loosening nuts, the non-hanging center structure effectively endures transportation vibrations. This comprehensive fastening strategy guarantees that all components remain securely in place during extended operations.

4. Vacuum processing:
Our meticulous vacuum process involves drying coils and cores, along with vacuum-filtering and injecting transformer oil. This process is crucial for minimizing internal moisture, ensuring long-term performance and reliability.

5. Oil tank design:
Crafted with corrugated sheets equipped with a breathing function, the oil tank design compensates for oil volume fluctuations due to temperature changes. Eliminating the need for an oil storage cabinet effectively reduces the transformer's height, optimizing its design.

6. Other features:
With a sleek and compact design, our oil-immersed transformers require minimal installation space and are ideal for maintenance-free operation, combining elegance with functionality.
These versatile transformers are widely implemented in power plants, substations, industrial and mining enterprises, as well as rural power grids, adeptly serving the power distribution system.

 

Environment and Requirements:
Ambient temperature: Optimal operation requires an ambient temperature spanning from -25°C to +40°C.
Altitude limit: The operational altitude should not surpass 1000 meters.
Air humidity: Relative humidity should be maintained below 90% at a temperature of +25ºC.
Installation place: Select an installation site that is free from corrosive gases and apparent dirt for optimal operation and longevity.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent inspections of the oil level and perform oil insulation strength tests. Promptly address any issues by replacing transformer oil as needed.
Stable operation: Ensure the transformer operates stably by preventing overloads, short circuits, and other anomalies that could compromise its functionality.
Safety attention: Prior to installation, address ventilation and fire prevention requirements according to technical specifications to ensure safe and proper placement.
