Oil-immersed Transformers Product Details:
Delve into the world of Oil-immersed Transformers, essential power equipment that stands as a cornerstone in power systems. Renowned for their efficiency, these transformers excel in voltage conversion and power transmission, tailored for systems with high current and large capacity demands. Their design promises exceptional stability and unwavering reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical, continuous or connecting continuous structure. This innovation enhances shock distribution, minimizes magnetic leakage, and boasts impressive mechanical strength, ensuring robust short-circuit resistance.

2. Iron core design:
Employing premium cold-rolled grain-oriented silicon steel sheets, this design utilizes a precision diagonal seam stacking method. The result? Drastically reduced no-load loss and minimized no-load current, epitomizing cutting-edge efficiency.

3. Fastening and anti-loosening:
Each core and winding is secured with meticulous fastening techniques. Equipped with self-locking anti-loosening nuts throughout, they feature a non-hanging center structure to endure transport vibrations. Fasteners are meticulously secured with nuts to ensure steadfast operation over time.

4. Vacuum processing:
Incorporating advanced vacuum processing, coils and cores undergo vacuum drying. Transformer oil is filtered and injected under vacuum conditions, effectively minimizing internal moisture to ensure optimal performance.

5. Oil tank design:
The oil tank showcases an innovative corrugated sheet with breathing capabilities, adeptly accommodating oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Boasting a striking appearance, compact size, and minimal installation footprint, these transformers are the epitome of ideal maintenance-free products for any power system.
Widely embraced across power plants, substations, and various industrial and mining enterprises, as well as rural power grids, these transformers are integral to efficient power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to range between -25°C and +40°C for optimal performance.
Altitude limit: Operation needs to be within an altitude not exceeding 1000m.
Air humidity: Maintain relative humidity below 90% at +25ºC for reliable operation.
Installation place: Choose areas devoid of corrosive gases and significant dirt accumulation for proper installation.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent checks on oil levels and perform oil insulation strength tests. Any issues detected should prompt immediate transformer oil replacement.
Stable operation: Ensuring stable transformer operation is crucial to preventing overloads, short circuits, and other anomalies.
Safety attention: Prior to installation, evaluate ventilation and fire prevention measures, adhering strictly to technical specifications for a flawless setup.
