Oil-immersed Transformers Product Details:
Our oil-immersed transformers are indispensable power equipment, seamlessly integrated into power systems to facilitate voltage conversion and power transmission. Engineered to meet the demands for high current and large capacity, these transformers offer unparalleled stability and reliability, making them a cornerstone in power distribution.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a multi-layer cylindrical, continuous, or connecting continuous structure, enhancing the winding's shock distribution, minimizing magnetic leakage, and ensuring high mechanical strength with robust short-circuit resistance.

2. Iron core design:
Utilizing premium cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, we significantly reduce no-load loss and no-load current, optimizing performance and energy efficiency.

3. Fastening and anti-loosening:
Each core and winding is secured with meticulous fastening techniques. High and low voltage leads boast self-locking anti-loosening nuts within a non-hanging center structure, ensuring resilience against transport vibrations. All fasteners are equipped with fastening nuts, maintaining integrity throughout prolonged operation.

4. Vacuum processing:
Our advanced vacuum drying process for coils and cores, paired with vacuum-filtered transformer oil, meticulously injected, minimizes moisture content within the transformer, ensuring optimal performance.

5. Oil tank design:
The oil tank's innovative corrugated sheet with a breathing function 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:
This product boasts a stunning aesthetic, compact dimensions, and a minimal installation footprint, rendering it the ideal maintenance-free solution for diverse power needs.
Our transformers are extensively deployed across power plants, substations, industrial and mining enterprises, and rural power grids, ensuring efficient power distribution in every sector.

 

Environment and Requirements:
Ambient temperature: Typically, operation requires an ambient temperature ranging from -25°C to +40°C, ensuring adaptability to various climates.
Altitude limit: Our equipment is designed to perform flawlessly at altitudes not exceeding 1000 meters.
Air humidity: Operating conditions require a relative humidity not exceeding 90% at +25ºC, ensuring optimal functionality.
Installation place: Select an installation site devoid of corrosive gases and noticeable dirt to maintain the integrity and longevity of the equipment.

 

Maintenance and upkeep:
Regular inspection: Consistent oil level checks and rigorous oil insulation strength tests are vital. Prompt replacement of transformer oil is necessary upon identifying any discrepancies, ensuring sustained performance.
Stable operation: Guarantee the transformer's stable operation by preventing overloads, short circuits, and other anomalies, preserving system integrity.
Safety attention: Pre-installation assessments should encompass plant ventilation and fire prevention strategies, adhering to technical specifications for precise and safe installation.
