Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as a cornerstone in modern power systems, expertly designed for seamless voltage conversion and robust power transmission. Tailored to meet high current demands and large capacity requirements, these transformers epitomize stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Boasting a high-voltage winding with multi-layer cylindrical, continuous, or connecting continuous structures, this design enhances shock distribution, minimizes magnetic leakage, and boasts superior mechanical strength and short-circuit resilience.

2. Iron core design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets using a diagonal seam stacking technique, this design significantly reduces no-load losses and no-load current.

3. Fastening and anti-loosening:
Each core and winding is secured with advanced fastening methods. High and low voltage leads are reinforced with self-locking anti-loosening nuts, employing a non-hanging center design for optimal vibration resistance during transport. All fasteners are outfitted with secure nuts, ensuring steadfast operation over time.

4. Vacuum processing:
Utilizing vacuum drying for coils and cores, and vacuum filtering for transformer oil, this meticulous process effectively minimizes internal moisture, enhancing performance.

5. Oil tank design:
The oil tank features corrugated sheets with an ingenious breathing function to adjust for oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet and consequently reducing the transformer's height.

6. Other features:
Aesthetically pleasing with a compact footprint, this maintenance-free marvel is an ideal solution, offering a small installation area.
Widely employed across power plants, substations, and industrial and mining enterprises, as well as throughout rural power grids within the power distribution network.

 

Environment and Requirements:
Ambient temperature: Ideally maintained within a range of -25°C to +40°C.
Altitude limit: should not exceed 1000 meters above sea level.
Air humidity: should not surpass 90% relative humidity, especially at +25ºC.
Installation place: Choose locations devoid of corrosive gases and noticeable dirt for optimal installation.

 

Maintenance and upkeep:
Regular inspection: Routine checks of the oil level and insulation strength are essential. Prompt oil replacement is crucial upon detection of issues.
Stable operation: Maintaining transformer stability requires vigilance against overloads and short circuits, ensuring uninterrupted performance.
Safety attention: Before installation, evaluate plant ventilation and fire prevention measures. Adhere strictly to technical guidelines for proper setup.
