Oil-immersed Transformers Product Details:
Our Oil-immersed transformers are renowned for their excellence in power conversion and transmission. Engineered for high current and voluminous capacity demands within power systems, they exemplify superior stability and dependability, ensuring seamless voltage adjustments for diverse applications.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Crafted with precision, the high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous structure. This design enhances shock distribution, minimizes magnetic leakage, and boasts high mechanical strength, ensuring robust resistance to short-circuits.

2. Iron core design:
Utilizing premium cold rolled grain-oriented silicon steel sheets, and an innovative full diagonal seam stacking method, our transformers significantly reduce no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Every component, including the core and windings, is secured with advanced fastening techniques. Equipped with self-locking anti-loosening nuts and a non-hanging center structure, our transformers endure transportation vibrations and maintain integrity over long-term operations.

4. Vacuum processing:
Advanced vacuum drying of coils and cores, and meticulous vacuum filtering and injection of transformer oil, ensures minimal moisture presence and optimal internal conditions for enhanced performance.

5. Oil tank design:
The intelligently designed oil tank features corrugated sheets with breathing functionality, accommodating oil volume changes due to temperature fluctuations. This eliminates the need for an oil storage cabinet, effectively reducing the transformer's height.

6. Other features:
Distinguished by its elegant appearance and compact size, our transformers are the quintessential maintenance-free solution, ideal for limited installation spaces.
Perfectly suited for power plants, substations, industrial, mining enterprises, and rural power grids, our transformers are integral to efficient power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimized for environments with temperatures ranging from -25°C to +40°C.
Altitude limit: Functional at altitudes not exceeding 1000 meters, ensuring versatile applications.
Air humidity: Operates efficiently in conditions with relative humidity up to 90% at 25ºC.
Installation place: Choose installation sites free from corrosive gases and significant dirt accumulation for optimal performance.

 

Maintenance and upkeep:
Regular inspection: Ensure regular checks of the oil level and insulation strength. Promptly replace the transformer oil when issues are detected to maintain operational integrity.
Stable operation: Commit to stable transformer operation by preventing overloads, short circuits, and other anomalies, safeguarding longevity and performance.
Safety attention: Prior to installation, evaluate plant ventilation and fire prevention measures. Adhere strictly to technical specifications for a flawless setup.
