Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment, highly acclaimed across power systems for their crucial roles in voltage conversion and power transmission. Crafted to meet high current and large capacity demands, these transformers stand out with unparalleled stability and reliability, making them indispensable in modern power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous structure, significantly enhancing winding shock distribution. This design ensures minimal magnetic leakage, superior mechanical strength, and exceptional short-circuit resistance.

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

3. Fastening and anti-loosening:
Robust fastening measures secure the core and windings, with self-locking anti-loosening nuts fortifying high and low voltage leads. Our non-hanging center structure withstands transportation vibrations, ensuring fasteners remain secure throughout prolonged operation.

4. Vacuum processing:
Our advanced vacuum processing technique involves vacuum drying of coils and cores, alongside vacuum filtration and injection of transformer oil, effectively minimizing internal moisture.

5. Oil tank design:
The innovative oil tank design features corrugated sheets with a unique breathing function, accommodating oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet, and reducing the transformer's height.

6. Other features:
Exuding elegance with its aesthetically pleasing appearance, this compact transformer requires minimal installation space, positioning it as the ideal maintenance-free solution.
Our oil-immersed transformers are extensively utilized in power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: generally required to be between -25°C and +40°C.
Altitude limit: not exceeding 1000m.
Air humidity: not more than 90% relative humidity (at +25ºC).
Installation place: Select a location devoid of corrosive gases and obvious dirt for optimal installation.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on the oil level and perform oil insulation strength tests. Promptly replace transformer oil if any issues arise.
Stable operation: Maintain the transformer's stable operation by preventing overloads, short circuits, and other anomalies.
Safety attention: Prior to installation, ensure adequate plant ventilation and address fire prevention measures, adhering to technical specifications for correct installation.
