Oil-immersed Transformers Product Details:
Oil-immersed transformers are pivotal power solutions, extensively utilized across power systems for efficient voltage conversion and seamless power transmission. Engineered to meet the demands of high current and large capacity requirements, these transformers stand out with unmatched stability and reliability, making them indispensable in power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical, continuous, or connecting continuous structure, enhancing the shock distribution of the winding. This design minimizes magnetic leakage, offers superior mechanical strength, and ensures robust short-circuit resistance.

2. Iron core design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, the iron core employs a full diagonal seam stacking method to significantly reduce no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Each core and winding is secured with reliable fastening measures. High and low voltage leads are equipped with self-locking anti-loosening nuts while adopting a non-hanging center structure to endure transportation vibrations. All fasteners are reinforced with locking nuts to prevent loosening during extended operations.

4. Vacuum processing:
Coils and cores undergo meticulous vacuum drying. Transformer oil is both vacuum-filtered and injected, ensuring minimal moisture presence within the transformer, thus enhancing its durability and performance.

5. Oil tank design:
The oil tank features corrugated sheets with a breathing function, accommodating oil volume changes due to temperature variations. The absence of an oil storage cabinet lowers the transformer's height, offering compactness and efficiency.

6. Other features:
With its elegant appearance, compact size, and minimal installation footprint, this transformer emerges as the ideal maintenance-free solution, perfectly blending aesthetics with functionality.
Widely used in power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers seamlessly integrate into the power distribution system, ensuring reliable performance.

 

Environment and Requirements:
Ambient temperature: Ideally maintained between -25°C and +40°C for optimal performance.
Altitude limit: Installation should not exceed 1000m altitude for best operation.
Air humidity: Should remain below 90% relative humidity at +25ºC to ensure efficient functioning.
Installation place: Select an area devoid of corrosive gases and noticeable dirt for installation, ensuring longevity and safety.

 

Maintenance and upkeep:
Regular inspection: Frequent inspections of oil levels and oil insulation strength are crucial. Prompt replacement of the transformer oil is necessary upon identifying any discrepancies.
Stable operation: Ensuring the transformer's stable operation is paramount. Avoid overloads and short circuits to maintain its optimal functioning and longevity.
Safety attention: Prior to installation, considerations regarding plant ventilation and fire prevention must be addressed, followed by adherence to technical specifications for correct installation.
