Comprehensive Oil-immersed Transformers Product Details:
Our oil-immersed transformers are pivotal in power systems, providing exceptional voltage conversion and power transmission capabilities. Crafted to meet the demands of high current and large capacity, they stand out for their unparalleled stability and reliability.

 

Deciphering the Model Meaning:

 

Outstanding Performance Characteristics:

1. Advanced Winding Structure:
High-voltage winding features a multilayer cylindrical, continuous, or connecting continuous structure, enhancing shock distribution, minimizing magnetic leakage, and ensuring high mechanical strength along with formidable short-circuit resistance.

2. Innovative Iron Core Design:
Employing superior cold rolled grain-oriented silicon steel sheets with full diagonal seam stacking, our design significantly minimizes no-load loss and no-load current, elevating efficiency.

3. Enhanced Fastening and Anti-loosening Techniques:
Each core and winding is secured with specialized fastening measures. High and low voltage leads are equipped with self-locking anti-loosening nuts, supported by a non-hanging center structure, ensuring resilience against transportation vibrations. All fasteners are accompanied by locking nuts, guaranteeing stability during prolonged use.

4. Precise Vacuum Processing:
The coils and cores undergo meticulous vacuum drying, while the transformer oil is expertly vacuum-filtered and injected, creating an optimal low-moisture environment within the transformer.

5. Efficient Oil Tank Design:
Featuring corrugated sheets with breathing capabilities to accommodate oil volume changes due to temperature fluctuations, our oil tank eliminates the need for oil storage cabinets, thus reducing transformer height.

6. Distinctive Additional Features:
Showcases a visually appealing design with compact dimensions and a minimal installation footprint, making it the ideal maintenance-free choice.
Extensively utilized across power plants, substations, industrial and mining enterprises, and rural power grids, proving invaluable in power distribution systems.

 

Environmental Conditions and Requirements:
Optimal Ambient Temperature Range: Ideally maintained between -25°C and +40°C for peak performance.
Altitude Specifications: Operates efficiently at altitudes not exceeding 1000m.
Air Humidity Parameters: Humidity should not exceed 90% relative humidity at +25ºC to ensure proper functioning.
Installation Site Guidelines: Select sites free from corrosive gases and significant dirt to maintain transformer integrity.

 

Maintenance and Upkeep Protocols:
Routine Inspection Schedule: Regularly monitor oil levels and conduct oil insulation strength tests, promptly replacing oil if deficiencies are detected.
Ensuring Stable Operation: Maintain stable transformer function by preventing overloads and short circuits through proactive management.
Critical Safety Considerations: Prior to installation, ensure the plant has adequate ventilation and fire prevention measures, installing in adherence to technical specifications.
