Oil-immersed Transformers Product Details:
Oil-immersed transformers stand as a cornerstone in power systems, expertly designed to facilitate voltage conversion and seamless power transmission. Engineered to meet the high current and substantial capacity demands of modern power systems, these transformers promise unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding boasts a sophisticated, multi-layer cylindrical structure, either continuous or connected continuous, enhancing shock distribution and minimizing magnetic leakage. This design ensures exceptional mechanical strength and robust short-circuit resistance.

2. Iron core design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, the iron core's full diagonal seam stacking method substantially reduces no-load loss and current, optimizing efficiency.

3. Fastening and anti-loosening:
Each core and winding is securely fastened, utilizing self-locking anti-loosening nuts on high and low voltage leads. The innovative non-hanging center structure withstands transportation vibrations, and extensive fastening ensures lasting stability against operation-induced loosening.

4. Vacuum processing:
Coils and cores undergo meticulous vacuum drying, while transformer oil is vacuum filtered and injected, effectively curtailing moisture ingress and enhancing transformer longevity.

5. Oil tank design:
Featuring a corrugated sheet with breathing capabilities, the oil tank compensates for volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
With a sleek appearance, compact size, and minimal installation footprint, this transformer is the epitome of maintenance-free excellence.
Ideal for power plants, substations, and industrial or rural applications, this transformer is essential in any power distribution system.

 

Environment and Requirements:
Ambient temperature: The ambient temperature should ideally range between -25°C and +40°C.
Altitude limit: Installation altitude should not exceed 1000m to ensure optimal performance.
Air humidity: Maintain air humidity below 90% at +25ºC for best results.
Installation place: Select a clean area, free from corrosive gases and obvious contaminants, to install.

 

Maintenance and upkeep:
Regular inspection: Consistently monitor oil level and test oil insulation strength; replace transformer oil promptly upon detecting issues.
Stable operation: Ensure uninterrupted operation by preventing overloads, short circuits, and other anomalies.
Safety attention: Prioritize ventilation and fire safety during installation, adhering to technical specifications for a flawless setup.
