Oil-immersed Transformers Product Details:
Oil-immersed transformers are an integral part of modern power systems, renowned for their exceptional performance in voltage conversion and power transmission. Expertly crafted for high-current and large-capacity demands, these transformers offer unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding is meticulously designed with a multi-layer cylindrical, continuous, or connected continuous structure. This innovative design enhances shock distribution, minimizes magnetic leakage, and boasts high mechanical strength with robust short-circuit resistance.

2. Iron core design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, the iron core implements a full diagonal seam stacking method, significantly reducing no-load loss and current.

3. Fastening and anti-loosening:
Both core and windings are securely fastened with advanced measures. The integration of self-locking anti-loosening nuts and a non-hanging center structure ensures resilience against transportation vibrations, guaranteeing long-term operational stability.

4. Vacuum processing:
Utilizing vacuum drying for coils and cores, alongside vacuum-filtered and injected transformer oil, this process effectively minimizes moisture within the transformer, enhancing its durability and performance.

5. Oil tank design:
Featuring a corrugated sheet oil tank with a breathing function, it smartly compensates for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and thus reducing the transformer's height.

6. Other features:
With a stunning appearance, compact volume, and minimal installation footprint, this transformer is the epitome of maintenance-free efficiency.
Ideal for power plants, substations, industrial sites, mining enterprises, and rural power grids, these transformers are indispensable in modern power distribution systems.

 

Environment and Requirements:
Ambient temperature: Designed to operate efficiently between -25°C and +40°C.
Altitude limit: Suitable for altitudes not exceeding 1000m.
Air humidity: Optimal performance at no more than 90% relative humidity (at +25ºC).
Installation place: Select an area devoid of corrosive gases and obvious dirt for optimal performance and longevity.

 

Maintenance and upkeep:
Regular inspection: Frequent checks of the oil level and insulation strength are essential. Issues should be promptly addressed by replacing the transformer oil.
Stable operation: To ensure optimal function, it's crucial to prevent overloads, short circuits, and other operational anomalies.
Safety attention: Prior to installation, thoroughly consider plant ventilation and fire prevention, adhering strictly to technical specifications for correct setup.
