Oil-immersed Transformers Product Details:
Our oil-immersed transformers stand as the pinnacle of power equipment, playing a crucial role in modern power systems by enabling efficient voltage conversion and seamless power transmission. Expertly crafted, they cater to the demands of high current and large capacity transformations with unwavering stability and unparalleled reliability.

Performance Characteristics:

1. Winding structure:
The high-voltage winding is ingeniously designed with a multi-layer cylindrical, continuous, or connecting continuous structure. This innovation enhances the winding's shock distribution, minimizes magnetic leakage, bolsters mechanical strength, and fortifies the transformer against short-circuits.

2. Iron core design:
We utilize top-tier, cold-rolled, grain-oriented silicon steel sheets, fashioned with a meticulous full diagonal seam stacking method. This reduces no-load loss and no-load current, enhancing efficiency.

3. Fastening and anti-loosening:
Every core and winding is securely fastened using advanced measures. High and low voltage leads are fortified with self-locking anti-loosening nuts and a non-hanging center structure, ensuring they withstand transport vibrations. Fasteners come with secure nuts to maintain integrity during long-term operation.

4. Vacuum processing:
Through vacuum drying of coils and cores, coupled with vacuum-filtered and injected transformer oil, we minimize internal moisture, ensuring optimal performance.

5. Oil tank design:
Our oil tank, designed with corrugated sheets for breathing, adeptly compensates for oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet decreases the transformer's height, optimizing space.

6. Other features:
With an elegant appearance, compact volume, and minimal installation footprint, our transformers are the epitome of ideal maintenance-free products.
Perfectly suited for power plants, substations, industrial enterprises, mining sectors, as well as rural power networks within power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically ranges from -25°C to +40°C, ensuring adaptability to various climates.
Altitude limit: Ideal for regions not exceeding an altitude of 1000m.
Air humidity: Must be maintained below 90% relative humidity at +25ºC to ensure optimal operation.
Installation place: Select locations devoid of corrosive gases and visible contaminants to ensure longevity and reliability.

 

Maintenance and upkeep:
Regular inspection: Consistently check the oil level and conduct oil insulation strength tests. Promptly replace transformer oil if discrepancies are detected.
Stable operation: Secure the transformer's stable operation by averting overloads, short circuits, and other anomalies.
Safety attention: Prior to installation, assess plant ventilation and fire prevention. Adhere to technical specifications for correct installation.
