Comprehensive Oil-immersed Transformers Product Details:
Oil-immersed transformers are pivotal power equipment, extensively used across power systems for seamless voltage conversion and power transmission. Tailored to meet the demands of high current and large capacity, these transformers promise unmatched stability and reliability, making them indispensable in modern power infrastructure.

 

Understand the Model Meaning:

 

Performance Characteristics that Set Us Apart:

1. Innovative Winding Structure:
The high-voltage winding employs a multi-layer cylindrical structure, which is either continuous or connecting continuous. This design optimizes shock distribution, minimizes magnetic leakage, and achieves exceptional mechanical strength and short-circuit resistance.

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

3. Robust Fastening and Anti-loosening Measures:
Each core and winding is secured with high-grade fastening measures. With self-locking anti-loosening nuts on high and low voltage leads and a non-hanging center structure, the design withstands transportation vibrations. All fasteners include sturdy fastening nuts, ensuring stability and reliability throughout prolonged operation.

4. State-of-the-art Vacuum Processing:
Employing advanced technology, both coils and cores undergo vacuum drying. Transformer oil is vacuum filtered and injected, minimizing moisture content and enhancing the transformer's longevity and efficiency.

5. Ingenious Oil Tank Design:
The oil tank features a corrugated sheet with a breathable function, accommodating oil volume changes due to temperature fluctuations. Without an oil storage cabinet, the transformer's height is reduced, ensuring space efficiency.

6. Additional Distinctive Features:
Showcasing an aesthetic design, compact size, and minimal installation footprint, these transformers are the epitome of maintenance-free excellence.
Prominently utilized in power plants, substations, industrial and mining sectors, as well as rural power grids within power distribution systems.

 

Optimal Environment and Requirements:
Ideal Ambient Temperature: Generally maintained between -25°C and +40°C to ensure optimal performance.
Altitude Specifications: Operational altitude should not exceed 1000 meters to maintain efficiency and safety.
Air Humidity Control: Relative humidity should remain below 90% at +25ºC to prevent any adverse effects.
Installation Site Requirements: Choose an area devoid of corrosive gases and significant dirt accumulation for installation.

 

Maintenance and Upkeep Best Practices:
Regular Inspection Protocols: Consistently monitor oil levels and conduct insulation strength tests. Promptly address any issues by replacing transformer oil when necessary.
Ensuring Stable Operation: Maintain steady transformer operations by preventing overloads, short circuits, and other anomalies.
Critical Safety Considerations: Prior to installation, assess plant ventilation and fire prevention measures, adhering strictly to technical specifications for accurate installation.
