Oil-immersed Transformers Product Details:
Oil-immersed transformers are quintessential power tools extensively utilized in power systems, primarily for seamless voltage conversion and power transmission. Crafted to meet the demands of high current and large capacity requirements in power systems, these transformers offer superior stability and unwavering reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical design with continuous or connecting continuous structures. This enhances winding shock distribution, minimizes magnetic leakage, and offers high mechanical strength along with robust short-circuit resistance.

2. Iron core design:
Incorporating premium cold rolled grain-oriented silicon steel sheets, our transformers utilize a full diagonal seam stacking method, significantly cutting down on no-load loss and no-load current.

3. Fastening and anti-loosening:
Each core and winding is securely fastened with advanced fastening measures. The high and low voltage leads are equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure to withstand transport vibrations. All fasteners come with locking nuts to ensure long-term operational stability without loosening.

4. Vacuum processing:
Our meticulous vacuum drying process for coils and cores, combined with vacuum-filtered oil injection, minimizes internal moisture, ensuring optimal transformer performance.

5. Oil tank design:
Featuring a corrugated oil tank with a breathing function, this design compensates for oil volume fluctuations due to temperature changes, eliminating the need for an oil storage cabinet, thus reducing the transformer's overall height.

6. Other features:
Our transformers not only boast a stunning appearance and compact size but also require minimal installation space, making them the quintessential maintenance-free solution.
Harnessed in power plants, substations, industrial, mining enterprises, as well as rural power grids, these transformers are integral to power distribution systems.

 

Environment and Requirements:
Ambient temperature: The ambient temperature should preferably range between -25°C and +40°C to ensure optimal performance.
Altitude limit: Operational altitude should not exceed 1000 meters for guaranteed efficiency.
Air humidity: Relative humidity should remain below 90% at a comfortable +25ºC to prevent any performance issues.
Installation place: Choose installation spots that are free from corrosive gases and visible contaminants to maintain transformer integrity.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent inspections of oil levels and perform oil insulation strength tests. Replace transformer oil promptly if any issues are detected.
Stable operation: Ensure consistent transformer operation by preventing overloads, short circuits, and other anomalies.
Safety attention: Prior to installation, consider plant ventilation, fire prevention, and adhere strictly to technical guidelines for accurate and safe installation.
