Oil-immersed Transformers Product Details:
Oil-immersed transformers are quintessential power equipment, extensively utilized across power systems to facilitate voltage conversion and seamless power transmission. Crafted to meet the demands of high current and substantial capacity, these transformers exhibit unmatched stability and reliability, serving as the backbone of advanced power systems.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous, or connective continuous structure, enhancing winding shock distribution, minimizing magnetic leakage, amplifying mechanical strength, and fortifying short-circuit resistance.

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

3. Fastening and anti-loosening:
Each core and winding is securely fastened with dedicated measures, equipped with self-locking anti-loosening nuts for high and low voltage leads. The innovative non-hanging center structure endures transportation vibrations, with all fasteners designed to remain secure throughout extended operations.

4. Vacuum processing:
Through vacuum drying of coils and cores, coupled with vacuum-filtered and injected transformer oil, this process ensures minimal moisture presence, enhancing the transformer's longevity and performance.

5. Oil tank design:
Featuring a corrugated sheet with breathing capability, the oil tank adjusts for volume changes due to temperature variations, eliminating the need for an oil storage cabinet and thereby reducing transformer height.

6. Other features:
Exhibiting a beautiful appearance, compact size, and minimal installation footprint, these transformers are the epitome of maintenance-free utility solutions.
Widely implemented in power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers are integral to power distribution networks.

 

Environment and Requirements:
Ambient temperature: Typically required to range from -25°C to +40°C.
Altitude limit: Should not exceed 1000 meters.
Air humidity: Relative humidity must not exceed 90% at +25ºC.
Installation place: Select an area devoid of corrosive gases and conspicuous dirt for optimal installation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of oil level and oil insulation strength are necessary. Issues identified require prompt transformer oil replacement to ensure optimal functionality.
Stable operation: Achieving stable transformer operation involves preventing overloads, short circuits, and other irregularities.
Safety attention: Prior to installation, it is crucial to assess plant ventilation and fire prevention, ensuring adherence to technical specifications for accurate installation.
