Oil-immersed Transformers Product Details:
Oil-immersed transformers are powerful and essential equipment extensively utilized in power systems, primarily designed for voltage conversion and efficient power transmission. Engineered for high current and large capacity demands within power systems, these transformers promise exceptional stability and unwavering reliability, making them indispensable in modern energy infrastructure.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding utilizes a sophisticated multi-layer cylindrical, continuous, or connecting continuous layout. This enhances the shock distribution across the winding, minimizes magnetic leakage, and delivers superior mechanical strength with robust short-circuit resistance.

2. Iron core design:
Incorporating premium cold-rolled grain-oriented silicon steel sheets with a precise full diagonal seam stacking approach, this design significantly reduces no-load loss and minimizes no-load current, ensuring performance efficiency.

3. Fastening and anti-loosening:
Both the core and windings are meticulously secured with advanced fastening techniques. High and low voltage lead fastening components feature self-locking anti-loosening nuts, supported by a non-hanging center structure that endures transportation vibrations. All fasteners are reinforced with fastening nuts to guarantee stability during prolonged operation.

4. Vacuum processing:
Coils and cores undergo vacuum drying, while transformer oil is meticulously vacuum-filtered and injected, ensuring minimal moisture levels within the transformer for optimal performance.

5. Oil tank design:
The oil tank, crafted with corrugated sheets featuring a breathing function, compensates for oil volume fluctuations due to temperature changes. This design eliminates the need for an oil storage cabinet, thereby reducing the transformer's overall height.

6. Other features:
Exhibiting a beautiful, compact design with minimal installation space requirements, this maintenance-free product is ideal for modern energy solutions.
Perfect for deployment in power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers serve as a vital component in power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to range between -25°C and +40°C.
Altitude limit: Should not exceed 1000m above sea level.
Air humidity: Should not surpass 90% relative humidity at +25ºC.
Installation place: Opt for areas free from corrosive gases and visible dirt to ensure optimal operation.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on oil levels and test oil insulation strength. Promptly replace transformer oil when issues are identified to maintain optimal functionality.
Stable operation: Ensure the transformer operates stably by preventing overloads, short circuits, and other anomalies.
Safety attention: Before installation, consider factors like plant ventilation and fire prevention. Follow technical specifications for correct installation to ensure safety and performance.
