Oil-immersed Transformers Product Details:
Our Oil-immersed transformers are the cornerstone of power systems, expertly crafted for seamless voltage conversion and power transmission. With a design tailored to meet high current and large capacity demands, they guarantee unparalleled stability and reliability within any power system.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding is crafted with a multi-layer cylindrical, continuous, or connecting continuous structure. This innovative design enhances the shock distribution of the winding, minimizes magnetic leakage, ensures high mechanical strength, and provides robust short-circuit resistance.

2. Iron core design:
Utilizing premium cold-rolled, grain-oriented silicon steel sheets with a full diagonal seam stacking method, our design significantly reduces no-load loss and minimizes no-load current, setting a new benchmark for efficiency.

3. Fastening and anti-loosening:
Our cores and windings are securely fastened with advanced fastening measures. High and low voltage leads are equipped with self-locking anti-loosening nuts, complemented by a non-hanging center structure to endure transport vibrations. All fasteners include nuts that ensure long-term stability without loosening.

4. Vacuum processing:
Through meticulous vacuum drying of coils and cores, along with vacuum filtering and injection of transformer oil, we achieve minimal moisture presence within the transformer, ensuring optimal performance.

5. Oil tank design:
Our ingeniously designed oil tank features corrugated sheets with a breathing function, adeptly compensating for oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet allows a reduced overall transformer height.

6. Other features:
Boasting a stunning appearance, compact size, and minimal installation footprint, our products are the epitome of maintenance-free excellence.
Our transformers find widespread application in power plants, substations, industrial, mining enterprises, and rural power grids within the power distribution system.

 

Environment and Requirements:
Ambient temperature: Optimally required to range between -25°C and +40°C.
Altitude limit: Should not exceed 1000m to ensure proper functionality.
Air humidity: Should maintain a maximum of 90% relative humidity (at +25ºC).
Installation place: Choose an area devoid of corrosive gases and significant dirt for installation.

 

Maintenance and upkeep:
Regular inspection: Regularly monitor oil levels and conduct oil insulation strength tests. Promptly replace transformer oil whenever issues are identified to maintain optimal performance.
Stable operation: Ensure stable transformer operation by preventing overloads and short circuits, thereby averting potential anomalies.
Safety attention: Prior to installation, consider plant ventilation, fire prevention, and adhere to technical specifications for correct installation.
