Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment, extensively utilized in power systems for efficient voltage conversion and power transmission. Precision-engineered for high current and large capacity demands, these transformers are renowned for their exceptional stability and unwavering reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous or connecting continuous structure. This design optimizes shock distribution, minimizes magnetic leakage, enhances mechanical strength, and provides robust resistance to short circuits.

2. Iron core design:
Crafted from high-quality cold rolled grain-oriented silicon steel sheets, employing the full diagonal seam stacking method, this design significantly reduces no-load loss and no-load current.

3. Fastening and anti-loosening:
Integrated fastening measures secure both the core and windings. High and low voltage leads feature self-locking anti-loosening nuts and a non-hanging center structure, ensuring stability during transport. All fasteners come with fastening nuts for long-term reliability.

4. Vacuum processing:
Coils and cores undergo vacuum drying, while transformer oil is vacuum filtered and injected, effectively minimizing moisture content within the transformer.

5. Oil tank design:
The oil tank features a corrugated sheet design with a breathing function, accommodating oil volume changes due to temperature fluctuations without the need for an oil storage cabinet, thus reducing transformer height.

6. Other features:
Exuding a beautiful appearance, with a compact volume and minimal installation footprint, these maintenance-free products are the ideal choice.
Widely employed in power plants, substations, industrial, mining enterprises, and rural power grids within the power distribution system.

 

Environment and Requirements:
Ambient temperature: Typically required to be within the range of -25°C to +40°C.
Altitude limit: Should not exceed 1000 meters.
Air humidity: Not more than 90% relative humidity, especially at +25ºC.
Installation place: Choose an area devoid of corrosive gases and noticeable dirt for installation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and oil insulation strength are essential. Any issues should prompt immediate replacement of the transformer oil.
Stable operation: To maintain stable transformer operation, prevent overloads, short circuits, and other irregularities.
Safety attention: Consider ventilation, fire prevention, and adhere to technical specifications for proper installation.
