Oil-immersed Transformers Product Details: Unveiling the Core of Power Solutions
Oil-immersed transformers represent a pinnacle of engineering in power equipment, widely embraced in power systems for their exceptional voltage conversion and power transmission capabilities. Tailored for high current demands and substantial capacity, these transformers offer unrivaled stability and reliability, ensuring seamless operation in the most demanding environments.

 

Model Meaning: Decoding the Design

 

Performance Characteristics: Bringing You Unmatched Power Stability

1. Winding structure: A Pledge to Mechanical Excellence
Our high-voltage winding uses a refined multi-layer cylindrical, continuous, or connecting continuous structure, enhancing the shock distribution significantly. Featuring minimized magnetic leakage, this design delivers high mechanical strength and exceptional short-circuit resistance, ensuring robust performance.

2. Iron core design: Maximizing Efficiency and Minimizing Losses
Crafted with premium cold-rolled, grain-oriented silicon steel sheets, our iron core employs a full diagonal seam stacking method. This innovative design dramatically reduces no-load loss and current, optimizing performance and ensuring energy efficiency.

3. Fastening and anti-loosening: Secure and Resilient
Our transformers feature meticulously designed fastening measures for both the core and windings. Equipped with self-locking anti-loosening nuts and a non-hanging center structure, they excel in enduring transportation vibrations. All fasteners include secure nuts, guaranteeing steadfastness during prolonged operation.

4. Vacuum processing: Purity and Performance
Vacuum drying of coils and cores, coupled with vacuum-filtered oil injection, minimizes moisture within the transformer, enhancing longevity and performance.

5. Oil tank design: Adaptive and Space-Efficient
Featuring a corrugated sheet design with a breathing function, our oil tank effortlessly compensates for oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height, offering a compact yet powerful solution.

6. Other features: Aesthetic and Practical Perfection
With an elegantly crafted appearance, compact volume, and minimal installation footprint, our oil-immersed transformers set the standard for maintenance-free operation, making them the preferred choice for diverse applications.
Our transformers are widely integrated into power plants, substations, industrial and mining enterprises, and rural power grids, forming the backbone of robust power distribution systems.

 

Environment and Requirements: Ensuring Optimal Conditions
Ambient temperature: Versatile Climate Adaptability Our transformers are designed to function optimally in ambient temperatures ranging from -25°C to +40°C, accommodating a variety of climatic conditions.
Altitude limit: Reaching New Heights Our equipment is crafted to perform seamlessly at altitudes not exceeding 1000m, ensuring adaptability across various terrains.
Air humidity: Humidity Resilience Our transformers withstand up to 90% relative humidity at +25ºC, maintaining performance integrity even in humid environments.
Installation place: Selecting the Ideal Locale Choose a location devoid of corrosive gases and evident dirt to ensure long-lasting performance and minimal maintenance.

 

Maintenance and Upkeep: Preserving Excellence
Regular inspection: Ensuring Longevity Frequent checks on oil level and insulation strength are essential. Prompt replacement of transformer oil is vital should any discrepancies arise, maintaining optimal performance.
Stable operation: Sustaining Performance For consistent and reliable transformer performance, avoid overloads and short circuits, adhering to operational guidelines.
Safety attention: Prioritizing Safety Consider ventilation and fire prevention measures prior to installation, following technical specifications for safe, correct installation.
