Oil-immersed Transformers Product Details:
Our state-of-the-art oil-immersed transformers are integral components in power systems, expertly engineered for the seamless conversion and transmission of voltage. They meet the demands for high current and large capacity, offering remarkable stability and reliability. Ideal for modern power systems, these transformers ensure superior performance.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding features a sophisticated multi-layer cylindrical, continuous or connecting continuous design, significantly enhancing shock distribution, minimizing magnetic leakage, and delivering high mechanical strength. This ensures robust short-circuit resistance, making it a leader in durability.

2. Iron core design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, our core uses a full diagonal seam stacking method. This innovation substantially reduces both no-load loss and no-load current, optimizing energy efficiency and performance.

3. Fastening and anti-loosening:
Each core and winding is meticulously fastened with protective measures, featuring self-locking anti-loosening nuts on high and low voltage leads. The non-hanging center structure withstands transportation vibrations. Our durable fasteners and nuts guarantee long-term operational stability.

4. Vacuum processing:
Our advanced vacuum processing involves drying coils and cores while filtering and injecting transformer oil under vacuum. This precise technique minimizes moisture content, ensuring longevity and reliability.

5. Oil tank design:
The innovative corrugated sheet oil tank features a breathing function to accommodate oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Combining aesthetic beauty with compact design, our transformers offer minimal installation space and are an ideal maintenance-free solution, perfect for diverse applications.
These versatile transformers are widely utilized across power plants, substations, industrial and mining industries, as well as rural power grids, making them essential in power distribution systems.

 

Environment and Requirements:
Ambient temperature: The operational ambient temperature is optimally set between -25°C and +40°C.
Altitude limit: Designed to function flawlessly at altitudes not exceeding 1000m.
Air humidity: Effectively operates under air humidity conditions not exceeding 90% relative humidity (at +25ºC).
Installation place: Select installation areas devoid of corrosive gases and obvious dirt to ensure optimal performance and longevity.

 

Maintenance and upkeep:
Regular inspection: Routine checks of oil levels and insulation strength are crucial. Prompt replacement of transformer oil is necessary when issues are detected to maintain efficiency and safety.
Stable operation: Ensuring the transformer's stable operation is critical. Preventing overloads, short circuits, and other anomalies is essential for sustained performance.
Safety attention: Prioritize ventilation and fire prevention during installation. Adhere strictly to technical specifications for correct and secure setup.
