Oil-immersed Transformers Product Details:
Oil-immersed transformers are essential power equipment extensively utilized within power systems, primarily serving the purpose of voltage conversion and facilitating power transmission. Engineered to meet the demands of high current and large capacity transformer usage in power systems, these transformers are renowned for their exceptional stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical, continuous or connecting continuous architecture, enhancing shock distribution capabilities. This results in minimized magnetic leakage, heightened mechanical strength, and superior short-circuit resistance.

2. Iron core design:
Employing high-quality cold-rolled grain-oriented silicon steel sheets with a meticulous full diagonal seam stacking method, this design significantly reduces no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
Both the core and windings are meticulously secured with robust fastening strategies. Key fastening components, including the high and low voltage leads, are equipped with self-locking anti-loosening nuts. The innovative non-hanging center design ensures resilience against transportation vibrations. Every fastener is fitted with locking nuts to prevent any loosening during prolonged operation.

4. Vacuum processing:
Coils and cores undergo a vacuum drying process, while transformer oil is vacuum filtered and injected, dramatically reducing internal moisture and enhancing transformer longevity.

5. Oil tank design:
The oil tank employs corrugated sheets with breathing functionality, seamlessly accommodating oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet reduces the transformer's height, contributing to a more compact design.

6. Other features:
With a stunning appearance, compact size, and minimal installation footprint, this transformer is the epitome of maintenance-free excellence.
Versatile and adaptable, these transformers are perfect for deployment in power plants, substations, industrial and mining enterprises, as well as rural power grids.

 

Environment and Requirements:
Ambient temperature: Generally maintained between -25°C and +40°C for optimal performance.
Altitude limit: Operable at altitudes not exceeding 1000 meters.
Air humidity: Humidity levels should not surpass 90% relative humidity at +25ºC to ensure efficiency.
Installation place: Select an installation site devoid of corrosive gases and significant dirt for maximum longevity.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and oil insulation strength test are crucial. Any issues necessitate immediate replacement of the transformer oil.
Stable operation: To guarantee the transformer's stable operation, it is imperative to prevent overloads and short circuits, maintaining seamless functionality.
Safety attention: Prior to installation, address ventilation and fire prevention considerations, following technical specifications for safe and correct installation.
