Comprehensive Oil-Immersed Transformers Product Details:
Witness the power of oil-immersed transformers! These indispensable power equipment marvels are widely embraced in power systems for their unmatched capabilities in voltage conversion and power transmission. Crafted for high current and large capacity demands in sophisticated power systems, they stand out with their remarkable stability and reliability.

 

Intricate Model Meaning:

 

Outstanding Performance Characteristics:

1. Ingenious Winding Structure:
Our high-voltage winding is a testament to advanced engineering, featuring a multi-layer cylindrical, continuous, or connecting continuous structure. This design significantly enhances the shock distribution, minimizes magnetic leakage, and offers high mechanical strength coupled with robust short-circuit resistance.

2. Innovative Iron Core Design:
Crafted from premium cold-rolled grain-oriented silicon steel sheets, our iron core utilizes an advanced full diagonal seam stacking method to significantly reduce no-load loss and no-load current, optimizing efficiency and performance.

3. Secure Fastening and Anti-Loosening Features:
To ensure utmost stability, the core and windings are meticulously fastened. High and low voltage leads are secured with self-locking anti-loosening nuts and feature a non-hanging center structure, making them resilient to transport vibrations. All fasteners come with specialized nuts to ensure they remain secure during extended operations.

4. Advanced Vacuum Processing Techniques:
Our innovative vacuum processing involves precise drying of coils and cores, complemented by vacuum-filtered and injected transformer oil, effectively minimizing moisture presence within the transformer for optimal performance.

5. Ingenious Oil Tank Design:
The thoughtfully designed oil tank features a corrugated sheet with breathing capability, accommodating oil volume changes due to temperature fluctuations while eliminating the need for an oil storage cabinet, thereby reducing the transformer's height.

6. Distinct Features & Advantages:
Boasting a beautiful aesthetic, compact form, and minimal installation footprint, this transformer is the epitome of a maintenance-free design, ideally suited for modern applications.
Extensively employed in power plants, substations, industrial and mining enterprises, alongside rural power grids, these transformers play a pivotal role within power distribution systems.

 

Environmental Conditions and Prerequisites:
Optimal Ambient Temperature: Typically recommended to range between -25°C and +40°C for best performance.
Maximum Altitude Limit: Should not surpass 1000 meters to ensure optimal functionality.
Permissible Air Humidity: Should remain under 90% relative humidity at +25ºC for ideal performance conditions.
Strategic Installation Place: Select locations free from corrosive gases and apparent dirt to ensure longevity and optimal functioning.

 

Routine Maintenance and Upkeep:
Regular Vigilant Inspection: Frequently monitor the oil level and conduct oil insulation strength tests. Address any issues promptly by replacing the transformer oil as necessary.
Consistent Stable Operation: Ensure the transformer's stable operation by safeguarding against overloads, short circuits, and other anomalies.
Imperative Safety Considerations: Prior to installation, ensure adequate plant ventilation and consider fire prevention measures in alignment with technical specifications for precise and secure installation.
