Performance Characteristics:

1. Winding structure:
Our high-voltage winding features a multi-layer cylindrical design, either continuous or connecting continuous, which optimizes shock distribution and minimizes magnetic leakage. This design ensures superior mechanical strength and exceptional short-circuit resistance, making it a cornerstone of transformer resilience.

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

3. Fastening and anti-loosening:
For robust construction, the core and windings are meticulously fastened, with high and low voltage leads secured by self-locking anti-loosening nuts. The innovative non-hanging center structure endures transport vibrations, while comprehensive fastening ensures long-term operational stability.

4. Vacuum processing:
Advanced vacuum drying of coils and cores, coupled with vacuum filtration and injection of transformer oil, ensures minimal moisture levels, thereby optimizing performance and longevity.

5. Oil tank design:
Our oil tank boasts a corrugated sheet design with breathing functionality, accommodating oil volume changes due to temperature shifts without the need for an oil storage cabinet, thus reducing the transformer's height for more versatile installations.

6. Other features:
With a sleek appearance, compact size, and minimal installation footprint, these maintenance-free transformers are the epitome of modern efficiency and sophistication.
Engineered for excellence, our transformers find widespread application in power plants, substations, industrial and mining enterprises, and rural power grids, seamlessly integrating into power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimally designed to function within ambient temperatures ranging from -25°C to +40°C, ensuring versatile application across diverse climatic conditions.
Altitude limit: Operational efficacy guaranteed at altitudes not surpassing 1000 meters, maintaining performance integrity across various geographical locations.
Air humidity: Functionality is preserved in environments with a maximum of 90% relative humidity at +25ºC, safeguarding against moisture-related challenges.
Installation place: Select installation locales that are devoid of corrosive gases and conspicuous dirt to maintain optimal operational conditions.

 

Maintenance and upkeep:
Regular inspection: Proactive maintenance necessitates frequent oil level checks and insulation strength tests. Prompt transformer oil replacement is advised at the first sign of potential issues, ensuring ongoing efficiency.
Stable operation: Safeguard the enduring stability of your transformer by preventing overloads, short circuits, and other abnormalities, ensuring reliable power distribution.
Safety attention: Prior to installation, address plant ventilation and incorporate fire prevention measures in line with technical standards to guarantee safe and correct setup.
