Delve into the specifics of our top-tier Oil-immersed Transformers:
Engineered for excellence, our oil-immersed transformers are critical in power systems for their essential roles in voltage conversion and power transmission. Crafted to meet the demands for high current and substantial capacity, these transformers are synonymous with superior stability and unmatched reliability.

 

Decoding the Model Meaning with clarity:

 

Unmatched Performance Characteristics that set us apart:

1. Innovative Winding Structure:
Our high-voltage winding boasts a multi-layer cylindrical, continuous or connecting continuous structure, greatly enhancing shock distribution, minimizing magnetic leakage, and ensuring high mechanical strength and robust short-circuit resistance.

2. Advanced Iron Core Design:
Utilizing premium cold rolled grain-oriented silicon steel sheets with a full diagonal seam stacking method, this design significantly reduces no-load loss and no-load current.

3. Superior Fastening and Anti-Loosening Features:
The core and windings are meticulously secured with fastening measures, including self-locking anti-loosening nuts on the high and low voltage leads. Our non-hanging center structure withstands transport vibrations. All fasteners are fortified with fastening nuts to prevent loosening during prolonged operation.

4. Precision Vacuum Processing:
With vacuum-dried coils and cores, and vacuum-filtered transformer oil, our process effectively minimizes internal moisture for optimal performance.

5. Innovative Oil Tank Design:
Our oil tank features a corrugated sheet with a breathing function to adjust for oil volume changes due to temperature shifts, eliminating the need for an oil storage cabinet, thus reducing transformer height.

6. Additional Remarkable Features:
Featuring an aesthetically pleasing appearance, compact volume, and minimal installation footprint, these products are the epitome of maintenance-free solutions.
Ideal for application in power plants, substations, industrial and mining enterprises, as well as rural power grids within power distribution systems.

 

Comprehensive Environment and Requirements Guide:
Optimal Ambient Temperature: Typically recommended to range between -25°C and +40°C for peak performance.
Altitude Limitation: Should not exceed 1000 meters for optimal functioning.
Air Humidity Specifications: Should maintain a relative humidity of no more than 90% at +25ºC.
Ideal Installation Location: Select a site free from corrosive gases and conspicuous dirt for optimal durability.

 

Maintenance and Upkeep Guidance:
Scheduled and Regular Inspection Protocol: Conduct frequent checks of the oil level and perform oil insulation strength tests. If any issues arise, replace the transformer oil promptly.
Ensuring Stable Operation: Maintain stable transformer operation by preventing overload, short circuits, and other irregularities.
Crucial Safety Guidelines: Prior to installation, assess plant ventilation and fire prevention measures, adhering to technical specifications for accurate installation.
