Oil-immersed Transformers Product Details:
Oil-immersed transformers, a cornerstone in power systems, excel in voltage conversion and power transmission. Crafted to meet high current and large capacity demands, they promise unparalleled stability and dependability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding employs a meticulously designed multi-layer cylindrical, continuous, or connecting continuous structure. This advanced configuration enhances shock distribution, minimizes magnetic leakage, and ensures high mechanical strength coupled with formidable short-circuit resistance.

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

3. Fastening and anti-loosening:
Fastening measures secure the core and windings, while self-locking anti-loosening nuts on high and low voltage leads ensure a sturdy structure capable of withstanding transport vibrations. All fasteners are equipped with nuts to prevent loosening during prolonged operation.

4. Vacuum processing:
In a stringent vacuum process, coils and cores are thoroughly dried and transformer oil is filtered and injected to minimize internal moisture, ensuring optimal performance.

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

6. Other features:
Boasting an elegant design and compact size, it occupies minimal installation space and is the epitome of an ideal maintenance-free product.
These transformers find extensive applications in power plants, substations, industrial sectors, mining enterprises, and rural power grids, proving invaluable in power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically ranges between -25°C and +40°C.
Altitude limit: should not exceed 1000 meters.
Air humidity: should remain below 90% relative humidity at 25ºC.
Installation place: Select locations devoid of corrosive gases and significant pollution to ensure optimal performance.

 

Maintenance and upkeep:
Regular inspection: Routine checks of oil level and insulation strength are essential. Prompt replacement of transformer oil is necessary if issues are detected.
Stable operation: Maintaining stable transformer operation is crucial to prevent overloads and short circuits. Vigilance against operational anomalies is imperative.
Safety attention: Before installation, address plant ventilation, fire safety, and adhere to technical specifications for accurate setup.
