Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment extensively utilized in power systems for seamless voltage conversion and efficient power transmission. Crafted to meet high current and large capacity demands within power systems, these transformers provide exceptional stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding features a sophisticated multi-layer cylindrical and continuous or connecting continuous structure, enhancing shock distribution for reduced magnetic leakage, heightened mechanical strength, and superior short-circuit resistance.

2. Iron core design:
Incorporating premium cold-rolled grain-oriented silicon steel sheets with an innovative full diagonal seam stacking method to significantly minimize no-load loss and no-load current.

3. Fastening and anti-loosening:
The core and windings are meticulously secured with advanced fastening techniques. High and low voltage leads are equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure to endure transportation vibrations. All fasteners include securing nuts to guarantee robustness during prolonged operation.

4. Vacuum processing:
Coils and cores undergo thorough vacuum drying, while transformer oil is expertly vacuum filtered and injected, ensuring minimal moisture presence within the transformer.

5. Oil tank design:
The oil tank features corrugated sheets with a breathing function, adeptly compensating for oil volume variations due to temperature changes, eliminating the need for an oil storage cabinet, and thereby reducing transformer height.

6. Other features:
The transformer boasts a stunning appearance, compact volume, and minimal installation space, making it an ideal maintenance-free solution.
Versatile application in power plants, substations, industrial and mining enterprises, as well as rural power grids within the power distribution system.

 

Environment and Requirements:
Ambient temperature: Typically required to range between -25°C and +40°C.
Altitude limit: Should not surpass 1000m.
Air humidity: Not exceeding 90% relative humidity (at +25ºC).
Installation place: Select an area devoid of corrosive gases and excessive dirt for optimal performance.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and oil insulation strength test are vital; replace transformer oil promptly upon identifying issues.
Stable operation: Ensure the transformer operates smoothly by avoiding overloads and preventing short circuits and other irregularities.
Safety attention: Prioritize plant ventilation, fire prevention, and adhere to technical specifications for proper installation.
