Oil-immersed Transformers Product Details:
Oil-immersed transformers, a cornerstone in power systems, excel in converting voltage and transmitting power. Crafted for high-current and extensive capacity needs, they offer unmatched stability and reliability, making them indispensable in the realm of power equipment.

 

Model Meaning:

 

Performance Characteristics:

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

2. Iron core design:
Incorporating top-tier cold-rolled grain-oriented silicon steel sheets, with a full diagonal seam stacking method, these transformers significantly cut down on no-load loss and no-load current, boosting efficiency.

3. Fastening and anti-loosening:
Rigorous fastening measures for the core and windings, coupled with self-locking anti-loosening nuts on high and low voltage leads, ensure the robust structure withstands transportation vibration. Fasteners equipped with locking nuts guarantee long-term stability.

4. Vacuum processing:
Through vacuum drying of coils and cores, combined with vacuum filtering and injection of transformer oil, moisture within the transformer is minimized, enhancing longevity and performance.

5. Oil tank design:
The oil tank's innovative corrugated sheet design with breathing capability accommodates oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and thereby reducing transformer height.

6. Other features:
Sleek and compact, these transformers are maintenance-free and occupy minimal installation space, making them an ideal choice for diverse settings.
Commonly deployed in power plants, substations, industrial and mining enterprises, as well as in rural power grids, these transformers are integral to the power distribution system.

 

Environment and Requirements:
Ambient temperature: Optimal ambient temperature ranges from -25°C to +40°C, ensuring efficient operation.
Altitude limit: Recommended installation at altitudes not exceeding 1000m for optimal performance.
Air humidity: Should not exceed 90% relative humidity at temperatures of +25ºC to maintain efficiency.
Installation place: Select an area devoid of corrosive gases and significant dirt to ensure longevity and performance.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on the oil level and insulation strength. Promptly address any issues by replacing transformer oil as necessary.
Stable operation: To maintain stable operations, prevent overloads and short circuits by adhering to recommended specifications.
Safety attention: Prioritize plant ventilation and fire prevention during installation, and follow technical specifications meticulously to ensure safety.
