Oil-immersed Transformers Product Details: Explore the features that set our transformers apart in quality and design.
Oil-immersed transformers are indispensable in modern power systems, expertly engineered for exceptional voltage conversion and seamless power transmission. These transformers cater to the high current and large capacity demands of power systems, ensuring top-notch stability and reliability.

 

Model Meaning: Unlock the significance behind our model numbers.

 

Performance Characteristics: Witness the extraordinary attributes that make our transformers stand out.

1. Winding structure: Innovative designs for superior performance.
The high-voltage winding features a multi-layer cylindrical, continuous or connecting continuous structure, enhancing shock distribution, minimizing magnetic leakage, and providing outstanding mechanical strength and short-circuit resistance.

2. Iron core design: Cutting-edge technology for optimum efficiency.
Our transformers utilize high-quality cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, ensuring reduced no-load loss and minimal no-load current.

3. Fastening and anti-loosening: Precision engineering for durability.
Both core and windings are securely fastened, with high and low voltage leads equipped with self-locking anti-loosening nuts. The non-hanging center structure enhances transportation vibration resistance, and all fasteners come with nuts to prevent loosening during extended operation.

4. Vacuum processing: Advanced techniques for purity and performance.
Coils and cores undergo vacuum drying, while transformer oil is vacuum filtered and injected, minimizing internal moisture and ensuring optimal functionality.

5. Oil tank design: Ingenious engineering for adaptability.
The oil tank's corrugated sheet with breathing function compensates for oil volume changes due to temperature variations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features: Aesthetic and practical advantages.
With its sleek appearance and compact size, our transformer occupies minimal installation space, making it the perfect maintenance-free solution.
Widely utilized in power plants, substations, industrial and mining enterprises, as well as rural power grids, our transformers are integral to power distribution systems.
