Discover the Details of Our Oil-Immersed Transformers:
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.

 

Interpretation of Model Specifications:

 

Key Performance Characteristics:

1. Advanced Winding Structure:
Our high-voltage winding utilizes a multi-layer cylindrical, continuous or connecting continuous structure, significantly enhancing shock distribution, minimizing magnetic leakage, ensuring high mechanical strength, and providing formidable short-circuit resilience.

2. Innovative Iron Core Design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, the full diagonal seam stacking method significantly reduces no-load loss and no-load current, optimizing energy efficiency.

3. Secure Fastening and Anti-Loosening Measures:
Each core and winding is meticulously fastened with specially designed measures. High and low voltage leads are secured with self-locking anti-loosening nuts, utilizing a non-hanging center structure to endure transport vibrations. All fasteners feature secure nuts to maintain integrity during extended operations.

4. State-of-the-Art Vacuum Processing:
Our meticulous vacuum drying process for coils and cores, combined with vacuum filtration and injection of transformer oil, effectively minimizes internal moisture, enhancing longevity and performance.

5. Cutting-Edge Oil Tank Design:
The corrugated sheet oil tank, with its innovative breathing function, compensates for oil volume variations due to temperature changes, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Additional Noteworthy Features:
Boasting a sleek appearance, compact size, and minimal installation footprint, our transformers are the quintessential maintenance-free solution.
Perfectly suited for power plants, substations, industrial enterprises, mining operations, and rural power grids, these transformers play a pivotal role in power distribution systems.

 

Environmental Conditions and Requirements:
Ambient Temperature Range: Optimal operational temperature ranges from -25°C to +40°C.
Altitude Limitations: Designed for altitudes not exceeding 1000 meters.
Air Humidity Constraints: Relative humidity should not surpass 90% at +25ºC.
Installation Site Selection: Choose installation sites free from corrosive gases and significant dirt for optimal performance.

 

Maintenance and Upkeep Guidelines:
Routine Inspection Protocols: Regularly monitor oil levels and conduct oil insulation strength tests. Promptly replace transformer oil if irregularities are detected.
Ensuring Stable Operation: Maintain stable transformer operations by preventing overloads, short circuits, and any irregularities.
Safety Precautions: Prioritize plant ventilation and fire prevention during installation in accordance with technical specifications to ensure correct setup.
