Oil-immersed Transformers Product Details:
Oil-immersed transformers are indispensable power equipment prominently utilized in power systems for seamless voltage conversion and efficient power transmission. Specifically crafted for meeting high current and large capacity transformer demands, these transformers boast exceptional stability and reliability.

 

Model Meaning:

 

Performance Characteristics:

1. Winding structure:
Our high-voltage winding utilizes a multi-layer cylindrical, continuous or connecting continuous structure. This design enhances shock distribution, minimizes magnetic leakage, ensures superior mechanical strength, and provides robust short-circuit resistance.

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

3. Fastening and anti-loosening:
Employing meticulous fastening measures for both core and windings, the high and low voltage leads come equipped with self-locking anti-loosening nuts. The innovative non-hanging center structure withstands transportation vibrations, while all fasteners come with sturdy nuts ensuring unwavering stability during prolonged operations.

4. Vacuum processing:
Both coils and cores undergo meticulous vacuum drying. Additionally, the transformer oil is vacuum filtered and injected to effectively minimize internal moisture, ensuring optimal performance.

5. Oil tank design:
The oil tank is ingeniously designed with corrugated sheets possessing a breathing function that compensates for oil volume variations due to temperature changes. Absence of an oil storage cabinet reduces transformer height, optimizing space.

6. Other features:
Featuring a stunning appearance, compact dimensions, and minimal installation space, this product is the quintessential maintenance-free solution.
Their widespread application spans power plants, substations, industrial and mining enterprises, and rural power grids within power distribution systems.

 

Environment and Requirements:
Ambient temperature: Typically required to stay within the range of -25°C to +40°C.
Altitude limit: Should not exceed 1000 meters.
Air humidity: Should remain below 90% relative humidity (at +25ºC).
Installation place: Choose a location devoid of corrosive gases and noticeable dirt for optimal performance.

 

Maintenance and upkeep:
Regular inspection: Consistently monitor oil levels and test oil insulation strength. Address any issues promptly by replacing transformer oil as necessary.
Stable operation: Ensure the steady operation of the transformer by preventing overloads and short circuits, among other potential anomalies.
Safety attention: Prior to installation, consider crucial aspects such as plant ventilation and fire prevention. Adhere to technical specifications for accurate installation practices.
