Performance Characteristics:

1. Winding structure:
Our high-voltage winding is crafted with a multi-layer cylindrical, continuous, or connecting continuous design, enhancing shock distribution and reducing magnetic leakage. The result is high mechanical strength and robust short-circuit resistance.

2. Iron core design:
Incorporating high-grade, cold-rolled grain-oriented silicon steel sheets with full diagonal seam stacking, our design significantly cuts down no-load loss and no-load current.

3. Fastening and anti-loosening:
Each core and winding is reinforced with robust fastening measures. Our innovative fastening parts, including self-locking anti-loosening nuts, are designed to withstand transport vibrations, ensuring stability during extended operations.

4. Vacuum processing:
State-of-the-art vacuum drying techniques for coils and cores, along with precision vacuum filtering and oil injection, minimize moisture, ensuring peak performance.

5. Oil tank design:
The oil tank features a corrugated sheet with a breathing function, adapting seamlessly to temperature-induced oil volume changes without requiring an oil storage cabinet, thus lowering the transformer's height.

6. Other features:
Sleek in design with a compact footprint, our transformers are maintenance-free and perfect for installations with limited space.
Our transformers are optimally used across power plants, substations, industrial and mining enterprises, and rural power grids, enhancing the efficiency of power distribution systems.

 

Environment and Requirements:
Ambient temperature: Ideal operational temperatures range between -25°C and +40°C.
Altitude limit: Effective up to altitudes not exceeding 1000m.
Air humidity: Maintained at a maximum of 90% relative humidity at +25ºC.
Installation place: Select installation sites that are free from corrosive gases and significant dirt to ensure durability and performance.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on oil levels and insulation strength. Prompt oil replacement is crucial if irregularities are detected.
Stable operation: Commit to preventing overloads and short circuits for unwavering transformer performance.
Safety attention: During installation, factor in ventilation, fire prevention, and adhere closely to technical protocols for flawless setup.
