Oil-immersed Transformers Product Details:
Oil-filled transformers use liquids for cooling, making them highly suitable for outdoor applications. They are more efficient, have longer service lives, and feature more reliable overload capabilities.Transformer is isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, enhance the operation reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical structure, either continuous or connecting continuous, significantly enhancing the shock distribution balance. This design ensures minimal magnetic leakage, boasting high mechanical strength and impressive short-circuit resistance.

2. Iron core design:
Utilizing superior cold rolled grain-oriented silicon steel sheets with an innovatively full diagonal seam stacking method, this design remarkably reduces both no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Both core and windings are meticulously secured with robust fastening measures. Vital components, including high and low voltage leads, are equipped with self-locking, anti-loosening nuts. The non-hanging center structure adeptly withstands transportation vibrations. All fasteners come equipped with fastening nuts, ensuring steadfast operation without loosening over time.

4. Vacuum processing:
Both coils and cores undergo a thorough vacuum drying process, while the transformer oil is meticulously vacuum-filtered and injected. This precise methodology minimizes moisture within the transformer, enhancing longevity and performance.

5. Oil tank design:
The oil tank, crafted with corrugated sheets, features a unique breathing function to adeptly compensate oil volume changes due to temperature fluctuations. Without an oil storage cabinet, the transformer's height is significantly reduced, promoting a more compact design.

6. Other features:
Boasting a sleek and elegant appearance, the design ensures a compact volume with minimal installation space requirements, making it the quintessential maintenance-free product.
This transformer finds extensive application in power plants, substations, as well as industrial, mining enterprises, and rural power grids, serving as a cornerstone in power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically necessitated to range between -25°C and +40°C for optimal operation.
Altitude limit: Should not surpass 1000 meters above sea level.
Air humidity: Should not exceed 90% relative humidity, particularly at +25ºC.
Installation place: An area devoid of corrosive gases and conspicuous dirt must be selected for installation.

 

Maintenance and upkeep:
Regular inspection: Frequent assessments of the oil level and oil insulation strength are essential. Any issues should prompt immediate transformer oil replacement.
Stable operation: Ensuring the transformer's stable operation is paramount. Preventing overload, short circuits, and other anomalies is crucial.
Safety attention: Prior to installation, considerations for plant ventilation, fire prevention, and adherence to technical specifications for correct installation are vital.
