Oil-immersed Transformers Product Details:
Our oil-immersed transformers represent a pinnacle of power equipment excellence, extensively utilized across power systems. Their primary function lies in the seamless conversion of voltage and efficient power transmission. Crafted to meet the demands of high current and large capacity, these transformers are renowned for their exceptional stability and unmatched reliability.

Performance Characteristics:

1. Winding structure:
The high-voltage winding employs a sophisticated multi-layer cylindrical structure, whether continuous or connecting continuous, enhancing the winding's shock distribution. It features minimal magnetic leakage, boasts remarkable mechanical strength, and displays robust short-circuit resistance.

2. Iron core design:
Incorporating the finest cold rolled grain oriented silicon steel sheets with a full diagonal seam stacking method, this design significantly reduces both no-load loss and no-load current, ensuring superior efficiency.

3. Fastening and anti-loosening:
The core and windings are meticulously secured with precise fastening measures. High and low voltage leads are reinforced with self-locking anti-loosening nuts, and the innovative non-hanging center structure withstands transportation vibrations. All fasteners are equipped with locking nuts to prevent loosening during prolonged operation.

4. Vacuum processing:
Through a meticulous vacuum processing technique, coils and cores are dried, and transformer oil is vacuum filtered and injected to ensure minimal moisture infiltration, safeguarding the transformer's longevity.

5. Oil tank design:
The innovative oil tank design utilizes corrugated sheets with a unique breathing function. This compensates for oil volume changes due to temperature fluctuations, allowing for a streamlined design without an oil storage cabinet, thereby reducing the transformer's overall height.

6. Other features:
Our transformers boast an aesthetically pleasing design, compact size, and a minimal installation footprint, making them the ideal choice for maintenance-free operations.
These transformers find widespread application in power plants, substations, industrial and mining enterprises, and rural power grids, making them an integral part of any power distribution system.

 

Environment and Requirements:
Ambient temperature: Typically, an ideal operating range is from -25°C to +40°C to ensure optimal performance.
Altitude limit: Designed for locations not exceeding an altitude of 1000 meters.
Air humidity: Operating best in environments with a relative humidity of no more than 90% at +25ºC.
Installation place: Select sites devoid of corrosive gases and excessive dirt to promote longevity and performance.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent assessments of oil levels and perform oil insulation strength tests. Promptly replace transformer oil if deficiencies are detected to maintain peak function.
Stable operation: For optimal transformer performance, ensure stable operations by preventing overloads, short circuits, and other potential anomalies.
Safety attention: Prior to installation, consider factors such as site ventilation and fire prevention. Adhere strictly to technical specifications for a flawless installation.
