Oil-immersed Transformers Product Details:
Our oil-immersed transformers are vital power systems equipment, excelling in voltage conversion and energy transmission. These transformers meet the demands for high current and large capacity, promising unmatched stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous structure, enhancing shock distribution, minimizing magnetic leakage, and offering superior mechanical strength and remarkable short-circuit resilience.

2. Iron core design:
Incorporating high-quality cold rolled grain-oriented silicon steel with complete diagonal seam stacking substantially cuts no-load loss and current, ensuring energy efficiency.

3. Fastening and anti-loosening:
Each core and winding is securely fastened with specialized measures. The high and low voltage leads of the body are fortified with self-locking anti-loosening nuts and a non-hanging center structure to withstand transport vibrations. Every fastening component includes nuts to prevent loosening during prolonged operation.

4. Vacuum processing:
Our advanced vacuum drying for coils and cores, along with the vacuum filtration and injection of transformer oil, effectively minimizes internal moisture, enhancing performance and longevity.

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

6. Other features:
Showcasing a beautiful appearance with compact size, these transformers require minimal installation space and offer ideal maintenance-free solutions.
These transformers are extensively utilized in power plants, substations, industrial and mining sectors, as well as rural power grids, enhancing efficiency in power distribution systems.

 

Environment and Requirements:
Ambient temperature: The ideal ambient temperature range is from -25°C to +40°C.
Altitude limit: Installation sites should not exceed an altitude of 1000m.
Air humidity: The relative humidity should not exceed 90% at +25ºC.
Installation place: Select an area devoid of corrosive gases and noticeable dirt for installation.

 

Maintenance and upkeep:
Regular inspection: It is essential to frequently monitor the oil level and conduct oil insulation strength tests. Any issues detected should prompt immediate replacement of the transformer oil.
Stable operation: To ensure seamless transformer performance, prevent overloads, short circuits, and any other operational anomalies.
Safety attention: Prior to installation, consider ventilation, fire prevention, and adhere strictly to technical guidelines for correct setup.
