Explore the Oil-immersed Transformers Product Details:
Our oil-immersed transformers are indispensable in power systems, expertly designed for seamless voltage conversion and robust power transmission. Engineered to meet high current and large capacity demands, these transformers offer exceptional stability and reliability, setting a new standard in power equipment.

 

Model Meaning: Unveil the significance behind our meticulously designed models, tailored to fit your unique power needs.

 

Performance Characteristics: Unmatched precision, durability, and efficiency define our transformers.

1. Winding structure: Ingenious design for optimal performance.
The high-voltage winding employs a sophisticated multi-layer cylindrical, continuous or connecting continuous structure. This innovation enhances the shock distribution across the winding, minimizes magnetic leakage, boosts mechanical strength, and ensures formidable short-circuit resistance.

2. Iron core design: Crafted for superior efficiency.
By adopting premium cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, our design significantly reduces no-load loss and no-load current, offering remarkable energy efficiency.

3. Fastening and anti-loosening: Built for endurance.
Each core and winding is securely fastened with advanced measures. Equipped with self-locking anti-loosening nuts, the high and low voltage leads are stabilized using a non-hanging center structure, designed to withstand transportation vibrations. All fasteners include fastening nuts, guaranteeing they remain secure during long-term operation.

4. Vacuum processing: Ensuring longevity and reliability.
Our meticulous vacuum drying of coils and cores, alongside vacuum filtering and injecting of transformer oil, effectively minimizes moisture content within the transformer, extending its lifespan.

5. Oil tank design: Innovative and efficient.
The oil tank features a corrugated sheet with a breathing function, adeptly compensating for oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet streamlines the design, reducing the transformer's height.

6. Other features: Excellence in design.
With its sleek appearance and compact form, it requires minimal installation space, making it an ideal maintenance-free product for modern power solutions.
Our transformers are extensively utilized in power plants, substations, industrial and mining enterprises, as well as rural power grids, seamlessly integrating into any power distribution system.

 

Environment and Requirements: Setting the stage for optimal performance.
Ambient temperature: Perfectly conditioned for any climate. Designed to operate efficiently within a temperature range of -25°C to +40°C, ensuring consistent performance.
Altitude limit: Reaching new heights. Recommended for use in areas not exceeding 1000 meters in altitude, maintaining optimal functionality.
Air humidity: Engineered for resilience. Operates flawlessly in environments with a relative humidity not exceeding 90% at 25ºC.
Installation place: Choose the perfect location. Select areas free of corrosive gases and significant dirt to maintain peak performance of the transformers.

 

Maintenance and upkeep: Ensuring enduring reliability.
Regular inspection: Vigilance for sustained excellence. Regularly inspect oil levels and conduct insulation strength tests. Address any issues promptly by replacing transformer oil to uphold efficiency.
Stable operation: Assurance of unwavering performance. Uphold the transformer's seamless operation by preventing overloads, short circuits, and other anomalies, ensuring reliable service.
