Oil-immersed Transformers Product Details:
Our Oil-immersed transformers are premium power equipment, essential for effective voltage conversion and power transmission in power systems. Engineered for high current and large capacity needs, these transformers promise unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical design, whether continuous or connecting continuous. This enhances shock distribution, minimizes magnetic leakage, boosting mechanical strength and exceptional short-circuit resistance.

2. Iron core design:
Utilizing top-tier cold rolled grain oriented silicon steel sheets with a full diagonal seam stacking technique, we achieve a significant reduction in no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
With steadfast fastening methods, both core and windings are securely held. High and low voltage leads feature self-locking anti-loosening nuts, while a non-hanging center design tolerates transportation vibrations. All fasteners include nuts ensuring stability during prolonged operation.

4. Vacuum processing:
Through cutting-edge vacuum drying, coils and cores are prepared, while transformer oil undergoes meticulous vacuum filtering and injection, effectively minimizing internal moisture.

5. Oil tank design:
Our innovative oil tank design incorporates corrugated sheets with a breathing function, accommodating oil volume changes with temperature, eliminating the need for an oil storage cabinet, thus reducing transformer height.

6. Other features:
Exhibiting a beautiful aesthetic, compact size, and minimal footprint, these products epitomize ideal maintenance-free solutions.
Perfectly suited for deployment in power plants, substations, industrial, mining enterprises, and rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to remain between -25°C and +40°C for optimal performance.
Altitude limit: Must not exceed 1000 meters to ensure proper functionality.
Air humidity: Should not exceed 90% relative humidity at a temperature of +25ºC.
Installation place: Choose an area free from corrosive gases and significant dirt buildup for installation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks on oil level and insulation strength tests are crucial. Immediate oil replacement is necessary upon detecting issues.
Stable operation: Guaranteeing stable transformer operation involves preventing overloads, short circuits, and other anomalies.
Safety attention: Ensure considerations for plant ventilation and fire prevention are addressed before installation, adhering to technical specifications for proper setup.
