Oil-immersed Transformers Product Details:
Oil-immersed transformers are a highly efficient category of power equipment, extensively utilized across power systems for their prowess in voltage conversion and power transmission. Expertly engineered to meet the high-current and large-capacity demands of power systems, these transformers exemplify unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

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

2. Iron core design:
Crafted from premium cold-rolled, grain-oriented silicon steel sheets, the iron core employs a meticulous full diagonal seam stacking method to dramatically reduce no-load loss and no-load current, optimizing efficiency.

3. Fastening and anti-loosening:
The robust core and windings are securely fastened with state-of-the-art fastening techniques. High and low voltage leads are reinforced with self-locking anti-loosening nuts, while adopting a non-hanging center structure to endure transportation vibrations. All fasteners are equipped with specialized nuts to guarantee long-term operational security.

4. Vacuum processing:
With precision, coils and cores undergo vacuum drying, and transformer oil is meticulously vacuum-filtered and injected to minimize moisture levels within the transformer, ensuring optimal performance.

5. Oil tank design:
The oil tank features an innovative corrugated sheet with a breathing function to accommodate oil volume fluctuations due to temperature changes, eliminating the need for an oil storage cabinet and thereby reducing the transformer's height.

6. Other features:
Featuring a sleek and attractive appearance, compact dimensions, and a minimal installation footprint, these transformers stand as the epitome of ideal maintenance-free products.
Ideal for deployment in power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: typically falling within -25°C to +40°C.
Altitude limit: should not surpass 1000 meters.
Air humidity: should remain below 90% relative humidity (at +25ºC).
Installation place: Should be chosen in areas devoid of corrosive gases and noticeable dirt for optimal installation conditions.

 

Maintenance and upkeep:
Regular inspection: Mandates frequent checking of oil levels and performing oil insulation strength tests. If issues arise, timely replacement of transformer oil is essential.
Stable operation: To ensure the transformer operates stably, it's crucial to prevent overload, short circuits, and other anomalies.
Safety attention: Prior to installation, ventilation and fire prevention measures must be addressed in accordance with technical specifications to guarantee correct installation.
