Oil-immersed Transformers Product Details:
Oil-immersed transformers serve as the backbone of power systems, essential for efficient voltage conversion and seamless power transmission. Crafted for high current and extensive capacity requirements, these transformers are meticulously engineered to ensure unparalleled stability and reliability across power networks.

 

Model Meaning:

 

Performance Characteristics:

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

2. Iron core design:
Utilizing premium cold rolled grain-oriented silicon steel sheets, and a full diagonal seam stacking method, the design significantly reduces both no-load loss and no-load current, optimizing overall transformer efficiency.

3. Fastening and anti-loosening:
The transformer's core and windings are securely fastened. High and low voltage leads are equipped with self-locking anti-loosening nuts, utilizing a non-hanging center structure to withstand transportation vibrations. Every fastener is meticulously secured with fastening nuts, ensuring long-term operational integrity.

4. Vacuum processing:
By employing vacuum drying for coils and cores, and vacuum filtering and injection of transformer oil, we dramatically reduce moisture levels within the transformer, enhancing durability and performance.

5. Oil tank design:
Our innovative oil tank design features corrugated sheets with a breathing function, accommodating oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height, offering a compact solution.

6. Other features:
Boasting a sleek appearance and compact dimensions, it occupies minimal space, ideal for maintenance-free operations, making it the perfect choice for modern installations.
These transformers find broad applications in power plants, substations, industrial and mining enterprises, as well as rural power grids, making them indispensable components in power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to range between -25°C and +40°C for optimal functionality.
Altitude limit: Installation should not exceed an altitude of 1000m.
Air humidity: Must not exceed 90% relative humidity at +25ºC to ensure operational efficiency.
Installation place: Choose an installation area free from corrosive gases and noticeable dirt to maintain transformer longevity.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and oil insulation strength test are crucial. Any anomalies should be addressed promptly by replacing the transformer oil.
Stable operation: To guarantee the transformer's stable performance, it is vital to prevent overloads and short circuits, ensuring consistent and reliable operation.
Safety attention: Prior to installation, ensure adequate ventilation and fire prevention measures are in place, adhering strictly to technical specifications for proper setup.
