Comprehensive Oil-immersed Transformers Product Details:
Oil-immersed transformers are a vital component in power systems, expertly crafted for efficient voltage conversion and reliable power transmission. Engineered to meet high demand for current and capacity, these transformers offer exceptional stability and dependability.

 

Understanding the Model Meaning:

 

Distinctive Performance Characteristics:

1. Advanced Winding Structure:
The high-voltage winding utilizes a multi-layer cylindrical, continuous, or connecting continuous structure, enhancing shock distribution efficiency, minimizing magnetic leakage, and providing robust mechanical strength along with superior short-circuit resistance.

2. Innovative Iron Core Design:
Utilizing premium cold-rolled grain-oriented silicon steel sheets, the full diagonal seam stacking method efficiently reduces both no-load loss and no-load current.

3. Enhanced Fastening and Anti-Loosening Features:
Core and windings are securely fastened with state-of-the-art measures, complemented by self-locking anti-loosening nuts for high and low voltage leads. The non-hanging center structure adeptly withstands transportation vibrations, ensuring fasteners remain intact during prolonged operation.

4. Superior Vacuum Processing Techniques:
Coils and cores undergo meticulous vacuum drying, with transformer oil being vacuum filtered and injected to significantly reduce internal moisture.

5. Ingenious Oil Tank Design:
The corrugated sheet oil tank features a breathing function, adapting to oil volume changes due to temperature fluctuations. The absence of an oil storage cabinet streamlines the design, reducing the transformer's height.

6. Additional Outstanding Features:
Exquisite aesthetics, compact size, and minimal installation footprint make these transformers ideal maintenance-free solutions.
Extensively utilized across power plants, substations, industrial and mining enterprises, and rural power grids in power distribution systems.

 

Environmental Considerations and Operating Requirements:
Optimal Ambient Temperature Range: Typically maintained between -25°C and +40°C for optimal performance.
Altitude Specifications: Should not exceed 1000 meters above sea level.
Air Humidity Guidelines: Relative humidity should not exceed 90% at +25ºC.
Preferred Installation Location: Choose an area devoid of corrosive gases and noticeable dirt for optimal installation conditions.

 

Maintenance and Upkeep Guidelines:
Routine Inspection Protocols: Regular assessment of oil levels and dielectric strength is crucial. Prompt replacement of transformer oil is necessary upon identifying any issues.
Ensuring Stable Operation: Maintain steady transformer operation by preventing overloads, short circuits, and other abnormalities.
Safety Precautions and Considerations: Prior to installation, address ventilation and fire prevention in compliance with technical specifications for correct setup.
