Oil-immersed Transformers Product Details:
Oil-immersed transformers serve as a vital component in power systems, primarily utilized for efficient voltage conversion and seamless power transmission. These transformers are meticulously crafted to meet the high current demands and large capacity requirements, ensuring unparalleled stability and reliability in power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical design, utilizing continuous or connecting continuous structures. This configuration substantially enhances the shock distribution, minimizes magnetic leakage, and offers superior mechanical strength, ensuring exceptional short-circuit resistance.

2. Iron core design:
Crafted from premium-quality cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, this design significantly reduces no-load loss and minimizes no-load current, optimizing the transformer's performance.

3. Fastening and anti-loosening:
Each core and winding is meticulously secured with robust fastening measures. High and low voltage leads feature self-locking anti-loosening nuts and a non-hanging center structure, capable of withstanding transportation vibrations. All fasteners are equipped with secure nuts, ensuring they remain intact during prolonged operation.

4. Vacuum processing:
Employing advanced vacuum drying techniques for coils and cores, along with vacuum filtering and injecting of transformer oil, this process minimizes moisture presence, ensuring optimal operational efficiency.

5. Oil tank design:
Engineered with a corrugated sheet oil tank featuring a breathing function, it compensates for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing the transformer's height.

6. Other features:
With an aesthetically pleasing design, compact size, and minimal installation footprint, this maintenance-free product is the ideal choice for modern power systems.
Our transformers are extensively utilized in power plants, substations, industrial and mining enterprises, as well as rural power grids, serving as a cornerstone in power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically required to be maintained between -25°C and +40°C for optimal performance.
Altitude limit: should not surpass 1000m to ensure efficiency and reliability.
Air humidity: should not exceed 90% relative humidity at +25ºC to maintain optimal operational conditions.
Installation place: Choose a location free from corrosive gases and evident contamination to prolong the product's lifespan.

 

Maintenance and upkeep:
Regular inspection: Frequent checks on oil level and oil insulation strength are essential. Address any discrepancies promptly by replacing transformer oil to maintain performance.
Stable operation: Ensure consistent transformer operation, avoiding overloads and preventing short circuits or other anomalies.
Safety attention: Prior to installation, consider plant ventilation and fire prevention measures, adhering strictly to technical specifications for proper installation.
