Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as a pivotal component in power systems, distinguished for their ability to efficiently convert voltage and transmit power. Crafted for demands of high current and large capacity, these transformers guarantee exceptional stability and reliability, making them indispensable in the realm of power systems.

Performance Characteristics:

1. Winding structure:
The high-voltage winding employs a multi-layer cylindrical design, available in continuous or connecting continuous structures. This innovation enhances shock distribution, minimizes magnetic leakage, and endows the transformer with superior mechanical strength and robust short-circuit resistance.

2. Iron core design:
By integrating top-tier cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking approach, our design significantly lowers no-load loss and no-load current, optimizing efficiency and sustainability.

3. Fastening and anti-loosening:
Every core and winding is securely fastened, with high and low voltage leads featuring self-locking anti-loosening nuts. Our non-hanging center structure absorbs transportation vibrations, while all fasteners come with fastening nuts to ensure stability during extended operations.

4. Vacuum processing:
With precision vacuum drying of coils and cores, alongside vacuum-filtered and injected transformer oil, this process drastically reduces moisture content, enhancing the transformer's longevity and performance.

5. Oil tank design:
The innovative oil tank features corrugated sheets with a breathing function, adeptly compensating for oil volume changes from temperature fluctuations. The absence of an oil storage cabinet results in a more compact transformer height.

6. Other features:
Boasting a sleek design and compact size, these products require minimal installation space and are the epitome of maintenance-free solutions, perfect for modern applications.
They are extensively utilized in power plants, substations, industrial and mining enterprises, and rural power grids, playing a critical role in power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically required to range from -25°C to +40°C, ensuring optimal performance in varied climates.
Altitude limit: should not exceed 1000m to maintain efficient operation.
Air humidity: must remain below 90% relative humidity at +25ºC, safeguarding the product's integrity.
Installation place: Should be selected in areas devoid of corrosive gases and noticeable dirt, ensuring longevity and efficiency.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of oil level and insulation strength are necessary. If issues are detected, prompt replacement of transformer oil is essential for optimal functionality.
Stable operation: Ensure transformers operate stably by preventing overloads, short circuits, and other anomalies, preserving system integrity.
Safety attention: Pre-installation assessments should address ventilation and fire prevention, following technical specifications for accurate setup.
