In-depth Insights into Oil-immersed Transformers:
Oil-filled transformers use liquids for cooling, making them highly suitable for outdoor applications. They are more efficient, have longer service lives, and feature more reliable overload capabilities.Transformer is isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, enhance the operation reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Harnessing a high-voltage winding with a multi-layer cylindrical, continuous or interconnecting continuous framework, this design enhances shock distribution, minimizes magnetic leakage, and boasts superior mechanical strength alongside exceptional short-circuit resistance.

2. Iron core design:
Employing premium cold-rolled grain-oriented silicon steel sheets with a fully diagonal seam stacking technique, this design significantly reduces no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Every core and winding is securely fastened with robust measures, complemented by self-locking anti-loosening nuts on high and low voltage leads, and a non-hanging center structure to withstand transport vibrations. Comprehensive fastening ensures stability during prolonged operation.

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

5. Oil tank design:
Crafted with corrugated sheets possessing breathing capabilities, the oil tank adeptly adjusts to temperature-induced oil volume changes, eliminating the need for an oil storage cabinet, thereby streamlining transformer height.

6. Other features:
Sleek and compact, the transformer occupies minimal installation space, embodying the ideal maintenance-free solution for modern power systems.
Perfectly suited for power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers form the backbone of power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimally set between -25°C and +40°C for peak performance.
Altitude limit: Restricted to a maximum of 1000 meters above sea level.
Air humidity: Capped at 90% relative humidity when at +25ºC to ensure efficient operation.
Installation place: Select an area devoid of corrosive gases and visible dirt for optimal longevity.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent inspections of oil level and insulation strength; promptly replace transformer oil upon detection of issues.
Stable operation: Ensure uninterrupted transformer functionality by averting overloads, short circuits, and other anomalies.
Safety attention: Prioritize plant ventilation and fire prevention measures in compliance with technical standards for precise installation.
