Performance Characteristics That Set Our Transformers Apart:

1. Winding structure:
The high-voltage winding is crafted using advanced multi-layer cylindrical and continuous structures, enhancing shock distribution, minimizing magnetic leakage, and offering superior mechanical strength and exceptional short-circuit resistance.

2. Iron core design:
Utilizing premium cold-rolled grain-oriented silicon steel sheets, our core design with a full diagonal seam stacking method dramatically reduces no-load loss and current.

3. Fastening and anti-loosening:
Each core and winding is secured with robust fastening methods, complemented by self-locking anti-loosening nuts and a non-hanging center structure to withstand transportation vibrations. Fasteners are equipped with nuts for long-term operational security.

4. Vacuum processing:
Our coils and cores undergo vacuum drying, while transformer oil is vacuum filtered and injected to minimize moisture, safeguarding the transformer's integrity.

5. Oil tank design:
The innovative oil tank with corrugated sheets compensates for oil volume changes due to temperature, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Aesthetically pleasing and compact, these transformers are maintenance-free and ideal for limited-space installations.
Extensively used in power plants, substations, and industrial sectors, as well as rural power grids, ensuring reliable power distribution.

 

Environment and Requirements:
Ambient temperature: Typically required to be between -25°C and +40°C for optimal performance.
Altitude limit: Should not exceed 1000 meters above sea level.
Air humidity: Should not surpass 90% relative humidity at +25ºC.
Installation place: Select locations free from corrosive gases and significant dirt for installation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of oil level and insulation strength are crucial. Prompt oil replacement is necessary if issues are detected.
Stable operation: Ensure steady operation by preventing overloads, short circuits, and other anomalies.
Safety attention: Ensure adequate ventilation and fire prevention during installation, adhering to technical specifications.
