Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment, highly favored for their efficacy in voltage conversion and power transmission across various power systems. Engineered to meet the demands of high current and substantial capacity requirements, these transformers boast exceptional stability and reliability, making them indispensable in power systems.

 

Model Meaning:

 

Performance Characteristics:

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

2. Iron core design:
Incorporating premium quality cold-rolled grain-oriented silicon steel sheets with a full diagonal seam stacking technique, this design significantly reduces no-load loss and minimizes no-load current for improved efficiency.

3. Fastening and anti-loosening:
Core and windings are meticulously secured with fastening measures. High and low voltage leads are equipped with self-locking anti-loosening nuts, adopting a non-hanging center structure to withstand transportation vibrations. This ensures all fasteners remain steadfast, preventing loosening during prolonged operation.

4. Vacuum processing:
Utilizing advanced vacuum processing, coils and cores undergo vacuum drying, while transformer oil is meticulously vacuum-filtered and injected, remarkably minimizing internal moisture for enhanced performance.

5. Oil tank design:
Featuring a corrugated sheet oil tank with breathing capability, this design effectively compensates for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and reducing transformer height.

6. Other features:
Showcasing a beautiful appearance, compact volume, and minimal installation space requirement, these transformers are the epitome of maintenance-free reliability.
Widely used in power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers are vital components in power distribution systems.

 

Environment and Requirements:
Ambient temperature: Ensuring optimal performance, the ambient temperature is generally required to be maintained between -25°C and +40°C.
Altitude limit: The recommended installation altitude should not exceed 1000m to ensure operational efficiency.
Air humidity: The relative humidity should not surpass 90% at +25ºC, preserving the integrity of the equipment.
Installation place: Choose installation locations free from corrosive gases and visible dirt, ensuring longevity and performance.

 

Maintenance and upkeep:
Regular inspection: Conduct frequent inspections on the oil level and perform oil insulation strength tests. Immediate replacement of transformer oil is necessary if issues are discovered.
Stable operation: For reliable transformer operation, it is crucial to prevent overloads and short circuits, ensuring consistent performance.
Safety attention: Prior to installation, consider adequate plant ventilation and fire prevention measures. Adhere to technical specifications for a correct and safe installation process.
