Oil-immersed Transformers Product Details:
Our oil-immersed transformers are distinguished power equipment, integral to power systems for their superior voltage conversion and seamless power transmission. Expertly crafted to meet high current and large capacity transformer demands, they offer unparalleled stability and reliability in power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding Structure:
With advanced multi-layer cylindrical, continuous, or continuous connection structures, the high-voltage winding showcases refined shock distribution, minimal magnetic leakage, exceptional mechanical strength, and formidable short-circuit resistance.

2. Iron Core Design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets using a full diagonal seam stacking technique, it significantly diminishes no-load loss and no-load current, ensuring efficiency and sustainability.

3. Fastening and Anti-Loosening:
Incorporating robust fastening measures, each core and winding is secured with self-locking anti-loosening nuts, adopting a non-hanging center structure to withstand transport vibrations. All fasteners are diligently outfitted with securing nuts ensuring steadfast stability during years of operation.

4. Vacuum Processing:
Employing precision vacuum technology, coils and cores undergo vacuum drying while transformer oil is meticulously vacuum filtered and injected, significantly curtailing internal moisture.

5. Oil Tank Design:
The innovative oil tank features a corrugated sheet with a breathing function, adeptly accommodating oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet, thus reducing the height of the transformer.

6. Other Features:
Boasting an aesthetically pleasing design, compact size, and minimal installation space requirement, these transformers are the epitome of maintenance-free excellence.
Expertly incorporated into power plants, substations, industrial, mining enterprises, and rural power grids, these transformers are crucial components within power distribution systems.

 

Environment and Requirements:
Ambient Temperature: Typically required to range between -25°C and +40°C.
Altitude Limit: Installation is recommended at altitudes not exceeding 1000m.
Air Humidity: Should not exceed 90% relative humidity at +25ºC for optimal performance.
Installation Place: Choose areas devoid of corrosive gases and noticeable contamination to ensure longevity.

 

Maintenance and Upkeep:
Regular Inspection: Conduct frequent checks on oil levels and perform oil insulation strength tests. Promptly replace transformer oil if any issues are detected.
Stable Operation: Maintain steady operation by preventing overloads, short circuits, and other anomalies, ensuring transformer integrity.
Safety Attention: Prioritize plant ventilation and fire prevention during installation, adhering to technical specifications for correct setup.
