Oil-immersed Transformers Product Details:
Our oil-immersed transformers stand as a cornerstone of modern power systems, expertly engineered for seamless voltage conversion and efficient power transmission. Designed to meet the rigorous demands of power systems requiring high current and large capacity, these transformers offer unparalleled stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
The high-voltage winding features a sophisticated multi-layer cylindrical design with continuous or connecting structures, significantly enhancing shock distribution, minimizing magnetic leakage, and providing exceptional mechanical strength and robust short-circuit resistance.

2. Iron core design:
Crafted with top-grade cold rolled grain-oriented silicon steel sheets and an expertly executed full diagonal seam stacking, our transformers minimize no-load loss and no-load current, setting a new standard in efficiency.

3. Fastening and anti-loosening:
Our transformers boast an innovative fastening system for both the core and windings, equipped with self-locking anti-loosening nuts and a non-hanging center structure, ensuring remarkable resilience during transportation vibrations. All fasteners are meticulously secured with nuts to guarantee stability throughout prolonged operation.

4. Vacuum processing:
The coils and cores undergo a meticulous vacuum drying process, while the transformer oil is expertly vacuum filtered and injected to virtually eliminate moisture within the transformer, enhancing longevity and performance.

5. Oil tank design:
Our innovative oil tank employs a corrugated sheet design with breathing functionality to adeptly compensate for oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet and thereby reducing the transformer's height.

6. Other features:
With a visually appealing design and compact size, these transformers are the epitome of space-efficient, maintenance-free solutions, perfectly suited for modern installations.
Universally applicable across power plants, substations, industrial and mining enterprises, as well as rural power grids, these transformers are essential in today's power distribution systems.

 

Environment and Requirements:
Ambient temperature: Optimally required to consistently range between -25°C and +40°C.
Altitude limit: Should not exceed 1000 meters to ensure optimal performance.
Air humidity: Maintain a maximum of 90% relative humidity at +25ºC for best results.
Installation place: Select an area devoid of corrosive gases and significant dirt to ensure longevity and efficiency.

 

Maintenance and upkeep:
Regular inspection: Frequent monitoring of the oil level and conducting oil insulation strength tests are essential. If any issues arise, timely transformer oil replacement is crucial.
Stable operation: Ensuring the transformer's stable operation involves preventing overloads, short circuits, and other irregularities.
Safety attention: Prioritize ventilation and fire prevention by adhering to technical guidelines to guarantee accurate and safe installation.
