Oil-immersed Transformers Product Details:
Oil-immersed transformers are an essential component of modern power systems, renowned for their versatility in voltage conversion and power transmission. Expertly engineered to meet high current and large capacity demands, these transformers offer exceptional stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical design with continuous or connecting continuous structures, enhancing shock distribution, minimizing magnetic leakage, and offering unmatched mechanical strength and short-circuit resistance.

2. Iron core design:
Crafted with premium cold-rolled, grain-oriented silicon steel sheets using a full diagonal seam stacking method, this design significantly reduces no-load loss and no-load current for optimized efficiency.

3. Fastening and anti-loosening:
With robust fastening measures, including self-locking anti-loosening nuts for high and low voltage leads, and a non-hanging center structure, the transformer withstands transportation vibrations. Each fastener is securely fitted to ensure unwavering stability during long-term operation.

4. Vacuum processing:
Utilizing advanced vacuum drying for coils and cores, coupled with vacuum-filtered oil injection, this process ensures minimal moisture content within the transformer, enhancing durability.

5. Oil tank design:
The innovative corrugated sheet oil tank design features a breathing function to accommodate thermal oil volume changes, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Boasting a sleek appearance and compact size, these transformers are ideal for maintenance-free applications, optimizing installation space.
These transformers are extensively utilized across power plants, substations, industrial and mining enterprises, as well as rural power grids, forming a critical part of power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically required to range between -25°C and +40°C.
Altitude limit: should not exceed 1000m.
Air humidity: should remain below 90% relative humidity (at +25ºC).
Installation place: Select an area devoid of corrosive gases and significant dirt to ensure optimal operation.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and oil insulation strength are essential. Any issues must be promptly addressed by replacing the transformer oil.
Stable operation: Continuously ensure stable transformer operation, preventing overloads and short circuits.
Safety attention: Prior to installation, consider ventilation, fire prevention, and adhere to technical specifications for correct setup.
